For Grab 21 inch Single Worm Slewing Drive
The characteristics of the slewing drive of Maanshan jingwei slewing ring Co., Ltd.:
1. It can get a lot of transmission force and is more compact than the staggered shaft helical gear mechanism.
2. The two-wheel meshing tooth surface is in line contact, and its bearing capacity is much higher than that of the crossed-axis helical gear mechanism.
3. The worm drive is equivalent to the screw drive, mostly the tooth mesh drive, so the drive is stable and the noise is very small.
4. Self-locking

Application in the field of engineering machinery claws: Engineering machinery auxiliary equipment is a brand-new application field of slewing drive. It adopts slewing drive as the claw of the swing mechanism, which makes the design structure more concise, more conducive to use and maintenance, and the worm gear drive has more The large reduction ratio makes the positioning accuracy of engineering tools such as claws greatly improved.
