The turntable bearing plays a supporting role in machinery. It is usually used in motors and engines. The material for making the turntable bearing needs to have a certain strength, and the production technology also needs to have a certain precision. There are many manufacturers of machinery that do not have this. Qualification, it is necessary to outsource this kind of parts to other qualified companies, so it is very important to choose a reliable turntable bearing manufacturer.
How to see the parameters of turntable bearing?
What is the reason for the broken teeth in the early stage of the turntable bearing?
What is the control method for the turntable bearing to produce scar sound?
The protection level of the turntable bearing is represented by IP X X, IP is the acronym for INGRESS PROTECTION, and X X is two numbers.
The first number indicates the level of dustproof and foreign object intrusion prevention of the rotary drive (foreign objects, including tools, foreign objects, human fingers, etc., should not come into contact with the internal moving parts of the rotary drive to avoid personal injury or equipment damage).
The second number indicates the waterproof ability of the slewing drive, and the larger the value, the better the waterproof ability of the slewing drive.
The first digit of the degree of protection of the slewing drive (dust rating).
There are two main reasons for the early failure of the turntable bearing for excavators: one is broken teeth; the other is raceway damage. Among them, broken teeth are the main reason, accounting for more than 90%, and most of them occur within six months after the excavator leaves the factory. This not only seriously troubles the product quality and reputation of the slewing ring manufacturer, but also has a negative impact on the product market of the main engine factory. Therefore, it is the common goal and responsibility of the slewing ring manufacturer and the main engine factory to solve this problem seriously, and it is also the further cooperation between the two parties. The fundamental guarantee of common development.
If the rolling surface of the turntable bearing is cracked, indented or corroded, periodic vibration and noise like riveting rivets will occur. The period may be fixed but most of them have a certain corresponding relationship with the rotation speed, and the scars will be continuous on the channel. Occurs, scars appear and disappear on the steel ball, and this noise varies with installation and lubrication conditions.
The control method of this kind of noise: do not knock the bearing during installation, prevent the bearing from tilting when assembling the bearing and the shaft and then put it into the bearing seat; prevent the bearing from rusting during stocking and prevent shock and vibration during transportation; use high-viscosity grease.
