Slewing Drive is a slewing bearing upgrade product, usually made of worm.Worm wheel slewing support.Housing. Composition of power source.The casing is made of high quality steel with very high strength. The worm gear and worm gear are all made of 42CrMo and diluted by glow ion, and the wear resistance is higher than the traditional domestic material of 50Mn made of gas nitride. Compared with other enveloping ring surface worm in China, the hardness is stronger and the service life is longer.

The slewing drive device can be basically divided into (single worm drive and double worm drive)

Features of worm gear and worm mechanism:

1. Can get a lot of power transmission, than the staggered shaft helical gear mechanism compact.

2. The meshing surfaces of the two wheels are in line contact, and the bearing capacity is much higher than that of the staggered shaft helical gear mechanism.

3. Worm transmission is equivalent to spiral transmission, which is mostly tooth meshing transmission, so the transmission is stable and the noise is very small.

4. With self-locking, when the leading Angle of the worm is less than the equivalent friction Angle between the meshing gear, the mechanism has self-locking, which can realize reverse self-locking, and can only drive the worm gear by the worm, but not by the worm gear.Such as in its heavy machinery used in the self-locking worm mechanism.Its reverse self - locking can play a role of security protection.

5. Low transmission efficiency and severe wear.When worm gear meshing transmission, the relative sliding speed between meshing gear teeth is large, so the friction loss is large and the efficiency is low.On the other hand, the tooth surface of the relative sliding speed is severely worn and heated. In order to dissipate heat and reduce wear, expensive materials with good wear resistance and good lubrication devices are often used, so the cost is relatively high.

6. Large axial force of worm
