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.

Slewing drive is consist of slewing bearing,worm shaft,housing,bearing,motor and so on. Motor drive the worm shaft, the outer ring of slewing bearing will rotate, the outer ring output the torque through flange while the inner ring of slewing bearing is fixed in housing.Slewing drive is able to sustain more axial load, radial load and tilting moment.Turntable or frame rotate at azimuth and elevation driven by slewing drive.Typical applications include solar trackers, wind turbines, satellite and radar dishes, truck cranes, man lifts, utility equipment, hydraulic equipment attachments, oil tool equipment, tire handlers, digger derricks, and automotive lifts.
 

Rotary drive slewing drive worm gear is a perfect combination of turbine worm products, worm ring surface envelope form, its tooth contact area is large, so the transmission torque is large, stable operation.
