采煤机行星头“抱死”原因分析

Analysis of Planetary Reduction Gearis Lock

行星头是采煤机的重要零件,在采煤机中起到重要的作用,因其工作原理和工况特殊,一旦出现问题将直接导致采煤机停产,而行星头抱死的主要原因是润滑油,因此及时注意行星头润滑情况,对防止行星头损坏的发生具有十分重要的意义。

The planetary reduction gearis is an important part of coal winning machine, because of its working principle and special working conditions. Mechanical failure will force production stopped of coal winning machine. Lubricating oil is main cause of planetary gear reducer, consequently in order to prevent the lock, we must pay more attention to the lubrication of planetary reduction gearis.
