Gear Type Slewing Drive
Gear type slewing drive
A gear-driven slewing drive is a type of drive mechanism that utilizes spur or helical gears meshing with a slewing bearing gear ring to achieve high-precision rotation. It converts the high speed and low torque of a motor into low speed and high torque 360° rotation. Its core difference from worm gear drives lies in the rigid gear meshing of the transmission pair, which lacks self-locking characteristics. Complementary to worm gear slewing drives, it excels in high transmission efficiency, high-speed adaptability, and heavy load capacity. It is a core rotating component for engineering machinery and heavy equipment, suitable for heavy-duty equipment such as port cranes, tunnel boring machines, rotary drilling rigs, and large industrial turntables.
