Slew drive is derived on the rotary bearing products with a high level of integration and big reduction ratio, and simple structure, convenient use and maintenance of special rotary reduction products, as a result of slewing bearing as the follower and frame foundation, using the rotary bearing inner and outer circle respectively drive power input and output, making 360 degrees rotation drive not only can realize the whole slew of weeks without dead point, and at the same time on the basis of slewing bearing frame installation drive power supply, so its high transmission efficiency, is a new member of the family of mechanical transmission device.Because its essence is a kind of reduction gear, so also can be called rotary speed reducer, wheel speed reducer or drive wheel.

Slewing drive according to different transmission can be divided into two categories, gear transmission and worm gear and worm drive, according to different transmission pair of closed form and can be divided into two categories, the open and closed, form the simplest rotation drive is used on the excavators, cranes and other construction machinery products of the drive wheel, as the final step of reduction drive chain, the rotation drive to open gear transmission, the front end also need to configure a big reduction ratio of the planetary gear reducer as its power input, so can only be called the embryonic form of rotation drive, to enlarge the application range of such products, further improve the product use and maintenance convenience,Developed integrated rotation drive worm gear and worm drive, in order to further improve the product's drive ability, enveloping worm drive has been applied in such products, equipped with enveloping worm rotation drive not only the drive torque increase, drive also further improve the precision, more can digitally control, therefore widely used in solar and wind power generation equipment on the track and fine-tuning device, the other in the robot, radar, lifting, lifting equipment, precision nc rotary table of low speed and heavy loading, and other areas of the product has good application effect.

Precision as backlash between worm shaft and slewing gear is very important for ensuing the working life and
efficiency.For all of the slewing drive made by Coresun Drive,we make the backlash testing 100%.
