Analysis of structure and construction principle of slewing bearing

2020-05-26

Parts often have their basic structure and related construction principles, and slewing bearings are all like this. Next, I will explain to everyone the basic structure and construction principles of related slewing bearings in detail.

　　Slewing ringThe basic structure:

The slewing ring is the same as the general bearing. It often has a turning body and a ring with a dovetail rail. But what is different is that the slewing ring has many different characteristics, as listed below:

1. The standard of slewing bearing is relatively large, and its straight length is generally 0.2-10 meters, and some straight lengths exceed 40 meters.

2. Slewing bearings generally need to accept loads of multiple levels of force, not only radial force and axial force, but also large overturning torque. Therefore, a slewing ring generally has the effect of multiple ordinary bearings.

3. The operating speed of the slewing bearing is slow, generally less than 50 revolutions per minute. In many places, the slewing bearing does not continue to operate, but only reverses the rolling within the angle of view, which is equivalent to "swaying the bearing".

4. At the level of production, manufacturing and processing technology such as raw materials and quenching and tempering, the slewing ring and the roller bearing are also quite far apart.

5. Generally, the slewing bearing contains the abs gear ring for the rolling drive and the sealing ring for anti-fouling, but the general roller bearing does not.

6. The installation method is different. The slewing bearing is not put on the mandrel and installed in the bearing cabinet like ordinary bearings, but it is fixed on the upper and lower rubber bearings by anchor bolts.

The construction principle of slewing ring:

The slewing ring is a giant bearing that can accept comprehensive loads. Its appearance design resembles a dish, so it is also called "slewing bearing". It can accept large radial loads, axial loads and overturning torque, and can replace several bodies. The general bearing is composed of functions used. Generally applicable to accept large overturning force

The industrial equipment for the relative rolling fitness exercise is a kind of combined bearing with high efficiency and high bearing capacity.

Because of the common characteristics of the slewing bearing itself, in more aspects, the slewing bearing has been used in various fields.
