High brightness axle bar is a cylindrical object which is worn between high brightness axle bar bearing or wheel or gear, but a few of them are square. High brightness axle bar is a mechanical part which supports and rotates with rotating parts to transfer motion, torque or bending moment. Generally, it is a metal rod with different diameters. The rotating parts of the machine are mounted on the high-brightness axle bar.

Cause of wear

The wear of high brightness axle rod is the most common equipment problem in the use of high brightness axle rod. There are many reasons for wear of high-brightness axle bar, but the main reason is that the metal characteristics used to make high-brightness axle bar are determined. Although the metal has high hardness, it has poor concession (it can not be restored after deformation), poor impact resistance and poor fatigue resistance, so it is easy to cause adhesion wear, abrasive wear, fatigue wear, fretting wear and so on, most of which are high. The wear of bright axle bars is not easy to detect. Only when there is high temperature, large jump range and abnormal noise of the machine, it will cause people to notice. But when people find out, most of the bright axle bars have been worn, resulting in machine shutdown.
