internal radial clearance

The factor affecting bearing internal radial clearance, the relationship between clearance and operating life time and fan failure process were discussed.

讨论了影响轴承游隙的因素和轴承游隙与轴承寿命的关系，并对轴承游隙过小而导致整个风机损坏的逻辑过程进行了推理。

The direct cause of this bearing 'failure was its improper assembly caused by improper maintenance procedure, and the root cause was too small internal radial clearance after mounting.

而非驱动端轴承损坏的直接原因是由于检修程序不完善使轴承在大修中安装不当所造成的，其根本原因则是轴承安装后游隙过小。

Through analyzing relative factors of effecting radial internal clearance and effecting degree to matching, so that relative size parameters were controlled, matching quality was raised.

调心滚子轴承配套时，受多种因素影响，通过对影响径向游隙的相关因素进行分析，来判断其影响程度，以便控制相关尺寸参数，提高配套质量。
