套圈沟道精度是构成轴承精度的主要部分。但是沟道精度究竟包括哪些方面?又怎样提高?我们从使用和制造工艺的实践中逐步认识逐步理解。特别是文化大革命以来通过厂内三结合攻关和与使用厂结合攻关,使轴承沟道精度逐步有所提高,反映在主机上是振动减小,寿命提高。现将这方面的工作汇报如下。 Ferrule channel accuracy constitutes the main part of the bearing accuracy. But what are the aspects of channel accuracy and how to improve? We gradually understand the practice of using and manufacturing process. Especially since the Cultural Revolution through the three-in-the-field research and the use of plant integration research, the bearing channel accuracy has gradually improved, reflected in the host is to reduce vibration and improve life expectancy. Now report on the work in this area as follows.
