Features and functions gear reducer

It uses a wide vertical gear reducer, as China's machinery manufacturing industry, transportation industry, construction industry and the textile and other industries have used. Lift the gear reducer is familiar, but not everyone could understand it, then the next gear reducer Xiaobian talk about what are the features and functions.
Gear reducer gears produced using advanced CNC grinding process, but also by the high carbon content of carbon steel and other metal alloys quenched from the combination. Between the gear set can make very precise fit, but also to have a long life, in favor of gear reducer to provide good mechanical power transmission equipment.
Gear reducer slowdown compared to similar products, the design more humane, higher carrying capacity. More lightweight, compact design saves lumber, does not occupy space, but also the mechanical equipment running more stable, reliable and can achieve high deceleration requirements in order to achieve a more perfect slowing effect.
In addition, the gear reducer can also be achieved by changing the device shifting torque requirements, for example spinning device can be achieved by setting the torque value different Shalei textile yarn, especially when the bobbin yarn of varying thickness To convert weaving, apart from the outside to set the appropriate weft density, the use of gear reducer to change the torque value is also very important.

Sealing requirements gearmotors

Worm gear reducer is usually installed in places with poor environmental conditions, the intake air containing particulate matter, dust, corrosive gases will affect the compressor lubricant life, proposals should consider installing intake filter, and should be regularly cleaned and replaced regularly intake air filter.
Seal gear reducer to note the following points:
Do not allow to fill the cabinet split between 1. face any pads, but can be applied sealant or water glass to ensure the seal;
2. When assembled, the cabinet before tightening the bolts, use of 0.05mm feeler cover and box seat sealing surface between the combination;
3. The shaft extension seal should be coated with grease. Each sealing device shall be strictly in accordance with the requirements of the installation.

Gear reducer oil change system

Gear reducer use in order to reduce the wear and tear require regular oil change, will introduce today RV Worm Gear Reducer oil change system you:
The first oil change is recommended after the machine run 300 to 400 hours lubricating oil should be replaced after every 1500 to 2000 hours to replace oil.
In poor working conditions, high temperature, large dust in the workplace should be every two weeks to conduct an inspection of the lubricating oil, lubricating oil dirt that is found to replace oil, lubricating oil in order to maintain clean and prolong the service life of the gearhead increase economic efficiency.
When gear reducer gearbox oil change to cool down to wait no fire danger so far, but should remain warm, because after completely cooled, increasing the viscosity of the oil, put the oil difficult. (Note: To cut off the transmission power to prevent inadvertently energized!).

Gear reducer temperature

I do not know how much you know about the problem cycloidal gear reducer, gear reducer easily affected by temperature. Here we give the analysis under the gear reducer is affected by temperature:
1, insulation material limit operating temperature means a gear reducer within the design life expectancy, the runtime hottest temperature insulation winding. If the operating temperature exceeds the limit long working temperature of the material, the insulation aging intensified greatly shorten life. So gear reducer in operation, the temperature is one of the main factors of life;
2, temperature is the temperature gear reducer and the environment is poor, is caused by the heat of the gear reducer. Temperature gear reducer design and operation is an important indicator, heating degree marks gear reducer, in operation, such as a Hypoid Gear Reducer temperature suddenly increases, indicating that the gear reducer is faulty, or duct obstruction or load is too heavy;
3, the operation of the gear reducer core in an alternating magnetic field will produce iron loss, will produce copper loss, there are other stray loss Once windings are energized. These will make the gear reducer temperature. On the other hand gear reducer will be cooling. When the heating and cooling that is equal to the equilibrium state, the temperature will not rise at a stable level. When the heat increase or decrease the heat will destroy the balance, so that the temperature continues to rise, expand temperature, then increase the heat to reach a new equilibrium at another higher temperature.

The highest gear reducer motor speed adaptation

Enter the maximum speed PC gear reducer motor adaptation, the general control of about 2000 rpm, high speed bearing seals for tolerance is a test for a long time there may be oil leakage. Here to tell you in detail below.
1, the rotation of the rotary gear reducer supported mainly by two bearings on which to support the increase of two bearing spacing, increase rotational stability and carrying capacity of the rotary gear. Using a round nut adjust the axial clearance between the two bearings, adjust convenient and reliable. To better ensure the normal operation of the rotary gear reducer;
2, gear reducer drive fast parametric modeling, the shape of the same or similar parts and serialization of products, a set of parameters can be used to characterize the structure size and attributes, by modifying the components of the various parameters to obtain different specification of components, to achieve parametric design;
3, for the gear reducer, the adoption of parametric modeling, users simply enter or modify some basic parameters of the gear (such as gear reducer teeth, modulus, pressure angle and tooth width, etc.), the software system will automatically generate three-dimensional geometric model of a certain type of gear or rebuild geometry, to improve design efficiency;
4, the geometric parameters of the gear teeth modulus gear name gear tooth pressure angle wide pitch circle diameter gear, the gear parametric modeling gear gearbox Hypoid Gear Reducer drive to establish virtual prototype model development set modeling, solving, visualization technology in one of the mechanical system dynamics simulation software can be used to predict the performance of mechanical systems, range of motion, collision monitoring, peak load and finite element calculation of input load and the like.

Gear motor means reducer and motor (motor) integrated body.

This integrated body would normally be referred to the vertical gear reducer or gear motor.
After integration usually assembled sets are supplied by professional reducer plant. variable gear motor are widely used in iron and steel industry, machinery industry and so on. The advantage of using gear motor is to simplify design, save space. After World War II, the rapid development of military electronic equipment to promote the United States, the Soviet Union and other countries of micro gear motor, DC geared motor development and production. With the continuous development of motor industry slowdown, more and more industries and businesses can use to slow down the motor, there are a number of companies into the motor industry slowdown. Currently, in the world of micro gear motor, DC geared motor on the market, Germany, France, Britain, the United States, China, South Korea and other countries to maintain a leading level. Chinese micro gear motor, DC geared motor industry was founded in the 1950s, from weapons and equipment to meet the need to start supporting, through imitation, to design, research and development, large-scale manufacturing stage, has formed a product development, large-scale production, the key components The key materials, manufacturing equipment, testing equipment and other supporting complete, increasing the degree of internationalization of the industrial system.

Geared Motor Description:

AC Motor Worm Gearbox AC single capacitor run motor, coupled with a suitable gear speed reducer, to achieve the required output of some kind, suitable for low-speed gear driven element, can play a simplified mechanical structure and reduce the role of energy consumption, according to their function points YY induction motor and YN type reversible motor are two, each can also increase the infinitely variable speed control. Some motors can be equipped with micro electromagnetic brake. YY induction motor suitable for continuous operation in one direction of the workplace, such as production lines, automatic machine tools, printing machinery. YN reversible motor is suitable for frequent start or commutation running applications, such as vending machines, packaging machines, voltage regulators, electric lift, electric actuators.

Geared Motor mounting arrangement

Features geared motors are high efficiency and reliability, long life, easy maintenance, widely used and so on. Its progression can be divided into single-stage, two and three gear motors, installation layout mainly expansion, coaxial and Split.
1, the two-stage expansion inside the cylindrical gear motor, gear position relative to the support asymmetry, when the shaft bending and torsion deformation generated, the uneven distribution of the load in the tooth width, and therefore should be designed with a large shaft stiffness, and the gear away from the input or output.
2, two hypoid gearbox Split features: external shunt geared motor shaft extension position may extend on either side, to facilitate the overall configuration of the machine, split level have Pc Helical Gear Box are made, while the right hand, while the left-handed to counteract the axial force, should make them do a little bit of a shaft axial swimming, so as not to get stuck gear.
3 features Helical geared motors: radial compact size, but larger axial dimension. Since the intermediate shaft is large, larger axis of flexing when under load, thus along the tooth width load on centralized phenomenon is more serious. And because the center of a two-stage gear must be consistent, so tell the carrying capacity level is difficult to make full use of the gear, and is located in the middle part of the deceleration bearing lubrication is also more difficult. The input and output of geared motors are located at both ends of the same axis, the overall configuration of the actuator to bring restrictions

Features geared motor

Characteristics of tough sturdy variable gear motor: internal material using a special heat treated alloy steel structure of a solid, wear-resistant, durable, superior performance and long life:
West Germany precision gear processing machinery, gear lease agreement dense vibration, low noise with a solid base to facilitate horizontal installation, vertical flange install it
In conjunction with the machine. Small AC Motor Worm Gearbox, light weight, quiet operation, with optional to follow with electromagnetic brake

Calculation of gearmotor reduction ratio

1, define the calculation method: reduction ratio = input speed ÷ output speed.
2. General Calculation method: Use a torque reduction ratio = ÷ 9550 ÷ × motor power motor power input revolutions ÷ utilization factor.
3. Calculation gear train: reduction ratio = ÷ driven gear driving gear teeth (if it is a multi-stage gear, the number of teeth will be driven initiative ÷ number of teeth all meshed pair of gears set, and then the results obtained by multiplying.
Representation is a general reduction ratio denominator, with ":" The ratio of input speed and output speed connections, such as the input speed is 1500r / min, the output speed is 25r / min, then the reduction ratio was: i = 60: 1. General reduction ratio marked reduction mechanism is the actual reduction ratio, but some special gear such as cycloid reducer or mechanical variable speed gearbox sometimes rounded by rounding, and do denominator, such as the actual reduction ratio may be 28.13, And when labeling generally designated 28.

Folding common types of geared motors

1) The main characteristics of the AC Motor Worm Gearbox is a reverse self-locking feature, you can have a greater reduction ratio, the input shaft and the output shaft axis is not the same, nor in the same plane. But generally larger, the transmission efficiency is not high, accuracy is not high.
2) Harmonic Harmonic Drive gear motor is controlled using a flexible element is elastically deformed to pass the motion and power, small size, high precision, but the downside is limited flexible wheel life, the impact of intolerance, rigidity and metal parts compared to the poor. Input speed is not too high.
3) the advantage of helical worm gearmotor structure is compact, small backlash, high precision, long life, rated output torque can do great. But the price is slightly more expensive. The input shaft of the gear teeth less output shaft of the large gear motors are generally used for low speed high torque transmission device, the internal combustion engine or other high speed electric motor powered by a gear motor to achieve the reduction goal, Common Geared motors on the same principle will also have a few gears to achieve the desired reduction effect than the size of the gear teeth is gear ratio.

Gear motor maintenance and how to maintain it? Oil change should pay attention to what the problem?

Maintenance method:
1, Cycloidal Speed Reducer Gearbox shall not exceed the rated load use.
2, after the gear is installed, check whether flexible. Official use please load test must be carried out under normal operating conditions, gradually loading operation.
3, deceleration machine before use and work should check the oil level is normal, the machine at the factory filled with oil, lubricants name: load industrial gear oil GB5903-86220.
Oil Change Note:
1, the first oil change after running gear 300 to 400 hours lubricant should be replaced after every 1500 to 2000 hours to replace oil. In poor working conditions, high temperature, large dust in the workplace should be every two weeks to conduct an inspection of the lubricating oil, lubricating oil dirt that is found to replace oil, lubricating oil in order to maintain clean and prolong the service life of the gearhead increase economic efficiency.
2, gear oil change to cool down to wait no fire danger so far, but should remain warm, because after completely cooled, increasing the viscosity of the oil, put the oil difficult. (Note: To cut off the transmission power to prevent inadvertently energized!)

Gearmotor is how oil change it?

helical bevel worm gearmotor at work after a certain time is needed for an oil change, usually run 200 to 300 hours after the first oil change should be carried out in future use should regularly check the quality of the oil, the incorporation of impurities or deterioration of the oil to be timely replacement. In general, for a long continuous operation since reducer speed machine, press run 5000 hours or once replaced with new oil every year, long-term disabled reducer, before re-operation should be replaced with new gear oil should be added to the same grade as the original Oil, not with different grades of oil mixed with, different grades of the same viscosity oil and allowed to mix.
variable gear motor to wait reducer oil change to cool down so far no fire hazard, but should remain warm, because after completely cooled, the viscosity of the oil increases, put the oil difficult.
