VE7 Hourglass Enveloping Worm Gear Slewing Drive For Single Solar Tracking System
Hourglass Worm Gear Slewing Drive Description
Slewing drives, also known as slewing ring drives or slewing ring bearings, are a type of gearbox that provides rotational movement in machinery applications. They consist of a slewing ring (a large bearing) and a drive mechanism, typically a worm gear or a spur gear system.
Hangtuo Mechanical, located in Changzhou, China, have enrich and expert knowledge on designing, developing and manufacturing slewing drives. We have more than 10 years’ experience. Our team is specialized in researches and developments in that particular area. Our experience covers the fields of tracking technologies for photovoltaic systems, mechanical engineering, slewing drive technology.

Working principle
The working principle of slewing drive is based on gear transmission. Through the torque provided by the motor or power source, the planetary gears in the drive mechanism transmit the torque to the outer ring gear and the inner ring gear, thereby rotating the entire slewing drive. The outer ring gear is connected to the slewing ring, and the inner ring gear is connected to the driving mechanism. By controlling the rotation of the drive mechanism, the rotation of the load connected to the slewing drive can be controlled.
Applications
Solar trackers including single axis solar tracking systems and dual axis solar tracking systems, wind turbines, satellite and radar dishes, truck cranes, man lifts, utility equipment, hydraulic equipment attachments, oil tool equipment, tire handlers, diggers, and automotive lifts.
