feature

Helical worm gearmotor using a worm gear and worm can get large transmission ratio, compact than interlaced helical gear mechanism for line contact between the two gear tooth surface, its carrying capacity and much higher than the interlaced helical gear mechanism, worm drive is equivalent to the spiral transmission, multiple tooth meshing transmission, so the stable transmission, noise is small, with self-locking. When the lead Angle of the worm is less than the equivalent friction Angle between the meshing teeth, the mechanism has self-locking and can realize reverse self-locking, i.e. it can only be driven by worm gear, and can not be driven by worm gear. If the self-locking worm mechanism is used in its heavy machinery, its reverse self-locking can play a safe and protective role. The transmission efficiency is low, the wear is more serious. When the worm gear meshing drive, the relative sliding speed between the meshing teeth is large, so the friction loss is large and the efficiency is low. Relative sliding velocity, on the other hand, ambassador of tooth surface wear serious, fever, in order to heat and reduce the wear and tear, often using relatively expensive antifriction and wear resistance of good material and good lubrication device, so the high cost, worm axial force is larger.

helical worm gearmotor

Advantages:

The two wheel meshes of helical worm gearmotor transmission are line contact, which can get better meshing effect than staggered shaft gear mechanism, and the transmission ratio and carrying capacity are higher. Worm gear and worm reducer drive is a kind of screw drive, drive in the main form of tooth meshing transmission, thus driving more smoothly, little vibration, low noise, suitable for need solid state machine. Worm gear and worm drive mechanism than other prominent advantage of the self-locking function, worm gear and worm drive mechanism of the worm lead Angle is less than the equivalent friction Angle between meshing tooth, will reverse self-locking worm gear and worm drive mechanism, it is also a worm drive the worm gear, the reason of unable to drive the worm and worm gear, so may not be into the shaft (hole) when the output shaft (hole) to use, or the output shaft (hole) when the shaft (hole) is used, it realized to protect the safety of the machine.

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.
