Brief introduction of precision reducer

A precision variable ratio gearbox is a power transmission mechanism that utilizes the speed converter of the gear to decelerate the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. Worm gear speed reducer is a relatively sophisticated machine, the purpose of using it is to reduce the speed, increase the torque.
PC gear reducer according to the accuracy can be divided into standard accuracy and high precision; according to the use can be divided into military and civilian; according to the operating environment can be divided into standard environment, low temperature environment, clean room environment and vacuum environment.

Cause of Worm Wear of Worm Gear Reducer

Worm gear generally used tin bronze, matching the worm material with 45 steel hardened to HRC4555, or 40Cr hardened HRC5055 after grinding by the worm grinding to roughness Ra0.8μm. vertical gear reducer normal wear and tear when the normal operation, some reducer can use more than 10 years. If the wear speed is faster, it is necessary to consider whether the selection is correct, whether the overload operation, and the worm PC gearboxes, assembly quality or use of the environment and other reasons.

What is the oil added to the cycloid reducer at the factory?

If the factory refueling, then, are generally grease, the use of molybdenum disulfide-2 or ZL-2 lithium grease and other grease
Because the factory single stage gearbox in order to facilitate handling and transport. Generally do not inject lubricants, before the injection of lubricants, recommended at room temperature using N150 extreme pressure industrial gear oil. Lubricant replacement cycle: reducer in the initial operation after 200 hours to be the first to replace the oil, the replacement should be to the residual oil. After the initial oil change, after continuous work every day lO hours or more Cycloidal Speed Reducer Gearbox. Should be replaced every 3 months of lubricants, work every day not more than 10 hours of reducer, should be replaced every 6 months a lubricant. Long-term use of the combined gearbox (usually more than 12 months) before re-use, you must replace the oil, different types of lubricants can not mix!

In the reducer family, high efficiency gearbox for its small size, high transmission efficiency, a wide range of deceleration, high precision and many other, and is widely used in servo, step, DC and other transmission systems. Its role is to ensure that the premise of precision transmission, mainly used to reduce the speed increase torque and cycloidal reducers the load / motor moment of inertia ratio. In the past few years, some users in the use of reducer, due to unauthorized installation and other human factors, which led to the output shaft of the reducer broken, so that enterprises suffered unnecessary losses. Therefore, in order to better help the majority of users with a good reducer, to you in detail how to correctly install the Hypoid Gear Reducer.
Correct installation, use and maintenance of reducer, is to ensure the normal operation of mechanical equipment important link. Therefore, when installing the planetary reducer, be sure to use the following installation in strict accordance with the following, carefully assembled and used.

Analysis on the Structure and Characteristics of Variable Speed ​​Reducer
Variable speed PC gear boxes, is a power transmission mechanism, which uses the gear speed converter, the motor speed of the number of deceleration to the desired number of revolutions, and get a larger torque device. Variable speed reducer is a relatively sophisticated machine, the purpose of using it is to reduce the speed, increase the torque. In the case of
wuma gearmotor mainly by the compression of the drive wheel device, friction Sassafras drive mechanism, speed control mechanism. In the case of
AC Motor Worm Gearbox performance is stable, high speed accuracy, variable speed range, combination of strong, and other advantages, widely used in food machinery, printing, paper machinery, rubber, plastic machinery, ceramic machinery, pharmaceutical machinery and various production lines Requires changes in process parameters and continuous changes in the speed of the occasion.

Reducer wear repair

The reducer is the key equipment of the vertical mill system. Since the mission of the helical bevel worm gearmotor is particularly bad, it is necessary to run continuously under the condition of shock, vibration and overload, and the service life is more than 15 years, and the reliability requirement is particularly high. , The use of vertical mill on the Hypoid speed gearbox design and manufacture of a higher demand.
Parts in the repair process, always in the normal temperature state, does not produce internal stress, no thermal deformation, crack, annealing, softening phenomenon, without breaking, the potential impact of cracking. Combined with high strength, does not produce off the phenomenon, no hard points, high surface finish, hardness adjustable.
Stainless steel, cast steel, cast iron, copper and copper alloys, aluminum and aluminum alloys, low carbon steel and low carbon alloy steel, medium carbon steel and medium carbon alloy steel, high carbon steel and high carbon alloy steel, high strength alloy steel , Zinc and zinc alloy, chromium, nickel, chromium nickel steel and unknown materials to repair.

Repair position accurate, flexible, repair the amount of control accuracy, but also can not disintegrate the scene repair, repair position can be tooling grinding technology to accurately restore the size. combined worm reducer for grinding cement, coal and other construction, chemical, ceramics and other industrial raw materials, with small size, light weight, small footprint, low power consumption, energy efficiency agreement more than 30%, long life and a series of advantages.
