Rotary drive device really appeared in the domestic market around 2006, when only one or two enterprises engaged in the production of the product, the market is mainly to meet the needs of foreign markets. In recent years, the domestic market has increased demand driven by rotation, which is mainly due to the state's investment in new energy exploitation. Rotary drive is mainly used in mechanical equipment which needs automatic tracking and positioning. During this period, it was also tried to be used in construction machinery. In the early stage, Xugong on-board crane and other units were tentatively used in engineering machinery equipment, and ultimately failed.

With the gradual rise of new energy fields, the accompanying equipment manufacturers have sprung up. The slewing drives are derivatives of slewing bearings, which are used in different fields.

Slewing drive is a kind of all-circumferential deceleration transmission mechanism which integrates driving power source. It uses rotary bearing as driving follower and mechanism attachment. By attaching the driving part, driving source and cover on one ring of the inner and outer rings of the rotary bearing, the other ring is regarded as both driving follower and connecting base of the driven working parts. It is the characteristic of the circumferential rotary connector itself. It is equipped with driving power source and main transmission parts efficiently, which makes it a universal deceleration transmission mechanism with the functions of rotation, deceleration and drive, simple structure and convenient manufacture and maintenance. The following article briefly introduces different types of slew drive and their applications, hoping to help you better understand the slew drive.

The dual axis slew drive is a new type of rotary product, usually called a slewing bearing, which is usually composed of a worm, a slewing ring, a case, a motor and the like. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and tipping moments. Compared with the traditional rotary products, the dual axis slew drive has the characteristics of simple installation, easy maintenance and more installation space saving. Slewing drives are mainly used in aerospace, tower cranes, excavators, construction machinery, conveyor machinery, elevators, aerial work, satellite receiving systems, solar tracking systems and many other industries.

Slewing drives function with standard worm technology, in which the worm on the horizontal shaft acts as the driver for the gear. The rotation of the horizontal screw turns a gear about an axis perpendicular to the screw axis. This combination reduces the speed of the driven member and also multipli

The solar trackers can be divided into single-axis trackers and dual-axis trackers by taking into account the mechanical characteristics. Since dual-axis systems are able to obtain an optimal tracking of the sun, they are more popular in all the types of concentrated solar technologies, with the exc
