1. Definition of slew drive
Slew drive device is a new type of rotary products, which is made of worm gear, slewing ring, shell and motor. Since the core part adopts slewing bearing, so it can bear axial force, radial force and overturning moment at the same time. Slew drive and traditional rotary products compared, it has the characteristics of simple installation, easy maintenance and saving installation space to a greater extent. This product can be widely used in heavy plate transport vehicle, container crane, truck mounted crane and high-altitude operation.
2. Slew drive structure
Slew drive can be divided into single worm drive, double worm drive and special type rotary drive. Xuzhou Wanda slewing bearing co.,ltd could supply the slew drive in SE Seires and WEA Series.
SE series adopts toroidal worm structure design, multi-tooth contact, strong impact resistance, suitable for light load and low speed applications. Such as solar tracker system,Small environmental protection equipment etc..
WEA series adopts curved tooth surface structure design, which has much stronger anti-fatigue and gluing ability. It is suitable for heavy-duty and medium-speed applications. Such as Construction machinery, construction machinery etc..
3. Three advantages of slew drive
a.)Modularization
Due to the high integration of the slew drive, users do not have to purchase and process each part of the rotary device one by one. To a certain extent, it also reduces the preparation process at the beginning of production, thus greatly improving the labor productivity.
b.)Security
Worm gear transmission has the characteristics of reverse self-locking, which can realize reverse self-locking, that is, only worm can drive worm gear, but not worm gear. The safety factor of main engine and slewing equipment can be greatly improved in high-altitude operation. Compared with traditional rotary products, slew drive has the advantages of simple installation, easy maintenance and saving installation space.
c.)Simplify host design
Compared with the traditional gear transmission, worm gear transmission can get a relatively large reduction ratio. In some cases, it can save the reducer parts for the main engine, so as to reduce the purchase cost for customers and greatly reduce the failure rate of the main engine.
