First, the definition of slewing drive

The slewing drive is a full-cycle rotary reduction transmission mechanism integrated with a driving power source. The slewing bearing is used as a transmission follower and a mechanism attachment member, and an active member, a driving source, and a ring are attached to a ring in the inner and outer rings of the slewing ring. The casing is used as both the transmission follower and the connecting base of the driven working part, so that the slewing bearing itself is a feature of the full-circle rotary joint, and the driving power source and the main transmission part are efficiently arranged. It makes it a general-purpose reduction transmission mechanism that integrates the functions of rotation, deceleration and drive, while having a simple structure and convenient manufacture and maintenance.

Second, the difference between rotary drive and slewing bearing

Due to the high integration of the rotary drive, the user does not have to purchase and process each component that constitutes the rotating device one by one, which also reduces the preparation process at the beginning of the production to a certain extent, thereby greatly improving the labor productivity. Compared with the traditional gear transmission, the worm gear transmission can obtain a relatively large reduction ratio. In some cases, the reducer components can be omitted for the main machine, thereby reducing the procurement cost for the customer and greatly reducing the host failure. rate.

Third, the classification and characteristics of the rotary drive

The slewing device adopts the transmission mode of the plane double enveloping toroidal worm and the slewing bearing to realize multi-tooth meshing, featuring large transmission torque and stable operation; at the same time, it can withstand large radial and axial loads and strong Overturning moment. Products are widely used in heavy-duty flat transport vehicles, aerial work vehicles, truck cranes, truck cranes, automated machine tool manufacturing, aerospace communications, and new energy fields represented by solar photovoltaic power generation and wind power generation.

Fourth, the application case of the slewing drive

    After years of practical application, ANHUI CHENGGUANG SEIKO ELECTROMECHANICAL TECHNOLOGY CO., LTD. summarizes the application fields: solar power, engineering machinery, forestry machinery, foundry, operation platform, organization, engineering, measurement technology, railcar, deep well mining,

Fifth, the selection basis of the slewing drive

The choice of reducer is a process of repeated calculations. First, select the reducer based on the load parameters, and then calculate whether the working point is at the limit load curve of the corresponding model. The starting torque of the reducer is not more than twice the rated torque. The mechanical efficiency of the reducer is 33%-40%
