China Good quality EGE21 Series Slewing Drive with Free Design Custom

The slewing drive is a slewing reduction mechanism with an integrated driving power source. The slewing ring is the central transmission part and the mechanical attachment. Its essence is a permanent magnet motor with ample torque. This product is also called a slewing reducer, a slewing drive. Compared with traditional rotary products, it is easy to install, maintain, and saves installation space to a greater extent. It is mainly used in beam trucks, aerial work vehicles, industrial robots, photovoltaic power generation, wind power generation, construction machinery claws, etc. field.

EGE21 series slewing drive, it is a kind of integration of driving power source of the week Slewing drive mechanism, it is 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 Slewing bearing itself is the week characteristics of Slewing 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.

Slewing Drive Characteristics

Slewing drives are unique on the market due to their versatility. While slewing drives are standard in size and external dimensions, custom and customer-specific requirements can be followed in the early design stages. The worm gear input can be modified to accommodate different motor input shaft sizes according to application requirements. Cast iron or aluminum end caps are bolted to both sides of the worm shaft to press the gears into place. This prevents axial play and provides better backlash control.

The standard orientation of the slewing drive is horizontal, allowing high axial loads and minimal radial loads. However, the vertical direction is widely distributed in different applications. The number of bolts and their distribution on the slewing drive surface play an essential role in the load capacity of the slewing drive. Still, custom modifications can be made to fit/replace the current models used by our customers.
