Slewing ring slewing drive

worm gear

The worm-gear type slewing drive is developed by the slewing bearing. It is composed of housing, a turbine ferrule, a worm gear, a motor and kits. Compared with the conventional slewing bearing, the structure is compacted, safe and modularity. The characteristics of modify the main engine. Nowadays, due to the demand for heavy loading, the duplex worm slew drive device has been developed. It has better product structure compactness and high loading ability and higher output torque. Slew drive can be widely used for 360° rotating and speed shifting, large torque smoothly transmission, high precision matching or compacted mechanism is mostly relied on slew drive, for its special solution and widely application below: Heavy loading gantry crane The slewing drive has changed the traditional mode of heavy loading gantry cranes in this field, greatly reducing operating costs and maintenance costs, it has been adopted by more and more host manufacturers by its effective. Aerial work vehicle field The slewing bearing motivates slewing drive which has developed rapidly and has obvious advantages in this field. Heavy loading flatbed truck (beam truck) Due to the heavy load, duplex worm slew drive are widely used for providing a large output torque. Port cranes While using a slew drive to fulfill the loading moment, the conventional hydraulic cylinder is another way to modify the rotating of slewing ring. New energy field With the support of national policies, the prospects of the rotary drive in this field are very impressive.
