Product Advantage
Slewing driver plays a very important role in the slewing bearing device. It can control the running speed of slewing bearing and adjust the speed of slewing bearing according to the reducer in emergency. Here are the four advantages of slewing bearing reducer.
1. High integration of slewing bearing reducer
Rotary type reducer is highly integrated, large and small rotary bearing reducer can drive the parts and load gap of tens of times, but their size, especially the axial size of the transmission chain is not big difference, this advantage is conducive to the series transmission connecting parts of the structural form of flat, so that the whole mechanical equipment to reduce.
2. The modularization of slewing bearing reducer
Because of the high integration of slewing bearing reducer, it is unnecessary for users to purchase and process each part of the rotating device, which also reduces the preparation process at the beginning of product production to a certain extent, thus greatly improving labor productivity.
3. Safety of slewing bearing reducer
Worm gear drive has the characteristic of reverse self-locking, which can realize reverse self-locking, that is, only worm drive worm gear, but not worm drive motion.This characteristic makes the slewing bearing reducer can be widely used in lifting, aerial work and other equipment, in improving the scientific and technological content of the main engine at the same time, also improve the stability of the main engine and the safety factor of the operation.Compared with the traditional rotary bearing reducer, it has the advantages of simple installation, easy maintenance and more saving installation space.
4. Simplified main engine design of slewing bearing reducer
Compared with the traditional gear transmission, worm gear transmission can obtain a relatively large reduction ratio. In some cases, it can save the reducer parts for the main engine, thus reducing the procurement cost for customers and greatly reducing the failure rate of the main engine.
