Gear shafts refer to mechanical parts that support rotating parts and rotate with them to transmit motion, torque or bending moment. Generally, it is in the shape of a metal round rod, and each segment can have different diameters. The parts that perform rotary motion in the machine are mounted on the shaft.

Jinyan Laser recently received a damaged gear shaft from a factory in Ghana, Africa. The material is 20CrMnMo. After inspection, the workpiece has two damages: angle drop and tooth surface damage.

Our company uses advanced repair technology to repair the gear shaft. After repairing the tooth shape, a hard layer is made on its surface to increase its hardness and wear resistance. After heat treatment, it is colored and inspected, and no other defects are displayed.

Analysis of the causes of gear shaft wear

Gear shaft wear is a common problem in enterprise equipment management and maintenance, and the number is large and damage is frequent.

The main reasons for wear are as follows:

1. The equipment is not installed properly, the maintenance is not timely, and the lubrication is poor;

2. Affected by vibration, pressure, impact and other forces, the impact of the matching parts is caused. Due to the high strength of the metal material and the poor concessionality, the long-term operation will inevitably cause the gap to continue to increase, so wear, cracks, fractures and other phenomena are also cannot be avoided;

3. The manufacturing quality is not high, and the heat treatment does not meet the requirements, which will cause wear and tear, and the shaft head will be broken in severe cases, which will have a major impact.
