Dual worm shaft slew drive is a new slew product, it is consisted of housing, worm gear ring, worm shaft, motor and other small parts. Compared with the single worm drive, dual worm slew drive still have the advantages of modularity, safety, and simplification of main engine design.
Rotation drive slewing drive, it is a kind of integration of driving power source of the week rotary reducer drive mechanism, its slewing bearing as transmission follower and adhesion mechanism, through the rotary bearing inner and outer circle a circle on the initiative of the cover, driving source and shell, and the other a circle both as a follower, and the connection of the base as driven working parts, so using the rotary bearing itself is the week characteristics of rotary joints, efficient allocation of driving power source and the main transmission parts, make it become a kind of rotary, slow down and drive function in a body and at the same time, simple structure, manufacture and maintenance convenient universal reduction drive mechanism.
According to the variable speed drive of rotation drive form, can be divided into type rotary gear rotation drive and the worm and worm wheel drive, inherit the characteristics of gear transmission and worm gear and worm drive each, are the two kinds of rotation drive can be adapted to high speed and low speed applications, in terms of bearing capacity, performance is superior to the tooth worm gear and worm type, and when envelope worm drive is used, its bearing capacity, deformation resistance and transmission have further improve rigidity, but the worm gear and worm type rotary drive in efficiency is inferior to tooth rotation drive.
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.
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.
