VE9 Vertical Worm Gear Slew Drive, Compact and High-Strength for Lifting and High-Altitude Operations
Vertical Worm Gear Slew Drive Description
1. Modularity
Due to the high integration of the rotary drive, users do not need to purchase and process each part of the rotating device one by one. To a certain extent, it also reduces the preparation procedures at the beginning of product production, thereby greatly improving labor productivity.
2. Safety
The worm gear drive has the characteristics of reverse self-locking, which can realize reverse self-locking, that is, the worm can only be driven by the worm, and the worm cannot be driven by the worm. This feature makes the rotary drive can be widely used in lifting, high-altitude operations and other equipment. While improving the scientific and technological content of the main engine, it also greatly improves the operation stability and safety factor of the main engine.
3. Simplify the host design
Compared with the traditional gear transmission, the worm gear transmission can obtain a relatively larger reduction ratio. In some cases, the reducer parts can be omitted for the main engine, thereby reducing the purchase cost for customers, and also greatly reducing the occurrence of main engine failure.
