Description

Scraper conveyer is the main transport equipment in underground coal mine, and its sprocket shaft group is the part that is easy to break down. In the working environment surrounded by coal and water for a long time, various failure forms will occur. The improvement of its working performance is the key to improve the performance of scraper conveyor.

Failure mode of sprocket body

Tooth surface pressure (scraper conveyor overload sprocket manufacturing poor quenching), fatigue broken teeth (long time overload), overload broken teeth (scraper conveyor overload start and sprocket material poor), abrasive wear (coal slag wear), plastic fold (scraper conveyor overload).

Failure mode of sprocket shaft

External spline wear (under overload and impact load for a long time), external spline fracture (sprocket shaft material is too poor), step or spline outlet fracture (service time exceeds life, it is fatigue fracture; Chronically overloaded).

Floating seal failure mode

Wear and deformation of O-ring (excessive surface pressure during assembly), wear and burn of floating sealing ring (excessive surface pressure during assembly); The design of the V port of the floating sealing ring is unreasonable, and the floating sealing ring has not been fully lubricated), oil leakage (the surface pressure is too small during assembly).

To understand the failure mode of sprocket components, analyze their causes and deal with the faults, so as to avoid affecting the operation of sprocket components of scraper conveyor due to the faults. To learn more about sprocket components, pay attention to the official website of Henan Shuanzhi.
