Advantages

1.For the situations where high torque is required, we introduce and recommend dual worm slewing drives which equip with worm wheel and have high scuffing resistance.

2.Driven by two worm, its output torque and performance is higher than that of single worm slew drive

3.Through excellent heat treatment,hardness of its is high

4.In the common case,our worm reducer is connect to hydraulic motor by universal input hole.

Production Photo and Application

Heavy-Duty Dual Worm Slewing Drive

Dual-worm slewing drive is usually installed horizontally, and mainly used in engineering machinery. As the worm gear is driven by two worm, it can output larger driving moment, more reliable self-locking performance and better safety performance in restricted space.And it is usually applied in occasions of low speed but larger moment, such as flat-form tire trolley and overhead traveling crane.  

Coresun Drive makes the metallographic analysis to ensure the quality of raw material to meet the requirement on slewing drive slewing bearing application.
