Parts often have its basic structure and related establishment principles, and slewing bearings are all like this. Next, let everyone explain the basic structure and establishment principles of related slewing bearings.
The basic structure of the slewing ring:
The slewing ring is the same as the general bearing. It often has a turning body and a ring with a dovetail rail. But the difference 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 usually plays the role of multiple general 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 run, but only rolls back in the angle of view, which is tantamount to "shaking the bearing".
4. At the level of production and processing technology such as raw materials and quenching and tempering treatment, 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. Only anchor bolts are used to fix it on the upper and lower rubber bearings.
The establishment 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 industrial equipment that accepts extremely large overturning moments for relative rolling fitness exercises is a combined bearing with high efficiency and high bearing capacity. Due to the common characteristics of the slewing bearing itself, in more aspects, the slewing bearing has been used in various fields.
