What is the function of slewing bearing?

The slewing bearing is a very useful machine part, and it has very powerful functions and help. It is very important for many factories to develop and study this product. How to choose a slewing bearing and do a good job in daily use? Let's take a look together, shall we?

How is the current development of the slewing bearing industry?

With the rapid development of various main engine industries, whether it is self-development, or imported technology, joint ventures or cooperation, the requirements for slewing bearings are increasing day by day. As a professional slewing bearing factory, it strengthens the development of new products, continuously improves product quality, and meets the development of main engines. Need is our duty and the fundamental requirement of market competition and self-development. However, how to correctly choose the structure type of the slewing bearing (single-row ball type, cross-roller type, double-row ball type, three-row column type, etc.) and size (roller center diameter D0, rolling body diameter d0), but due to the external load It is a complex force system and the mechanism of the bearing capacity of the raceway has not been deeply understood. There are some unreasonable conditions in the selection, which affect the economic benefits of the main engine industry, and even lead to major quality accidents, thus causing the main engine industry and the slewing bearing industry. common attention.

What is the root cause of the early failure of the slewing bearing due to broken teeth?

The working condition of the excavator is worse than that of the main engine in most industries that use slewing bearings, such as tower cranes and truck cranes. Indisputable fact. Therefore, the modulus of the slewing bearing for excavators is one step larger than that of the slewing bearing for the main engine of other industries with the same raceway diameter, and it is a hard tooth surface (generally, different hardness segments are selected between 47HRC and 58HRC), which basically meets the requirements. Excavator requirements for slewing bearing gears. Although statistics show that the probability of early tooth breakage of the slewing bearing for excavators is greater than that of other main engines, it is limited to very few two or three types of excavators, and most models rarely have slewing bearing early broken teeth accidents.

How to maintain the slewing bearing?

Before introducing the method, let's first understand that there are two common causes of slewing bearing failures. The first is the normal wear and tear during the construction of the machine, and the second is that you have wrong operation or improper maintenance during the operation and maintenance process!

For example, the slewing bearing is not greased in time, or more butter is added at one time to save trouble, because adding too much butter will push the sealing ring out, and some machine friends think that it is more difficult to handle and do not install it, which will accelerate wear and tear. A bigger failure occurs.

The slewing bearing has achieved an irreplaceable position in industrial production. LYXQL slewing bearing Co., Ltd. , Ltd. is committed to providing various slewing bearings of high quality for all customers from all over the world.
