1·The repair of ventilator axle journal with serious wear was achieved by using the method of laser cladding.

采用基于激光熔覆的方法实现了大磨损量的风机轴颈的修复。

2·With the axle journal protection sleeve in disassembling of wheels, the problem of down grading can be solved well.

应用解轮轴颈保护套可以较好地解决“降级”问题。

3·With this scheme, the automatic positioning and measurement of the axle journal is realized, the manual measurement error is reduced, and the scheme is fairly practical.

该方案实现了轴颈的自动定位和测量，减小了人工测量误差，实用性较强。
