转轴磨损,是一种经常出现的机械故障,特别是在庞大笨重的胶辊、石辊、圆网笼等两端带紧定套的滚动轴承,在维修中更难于处理。产生这类机械故障的主要原因是:1、滚动轴承紧定套与转轴的配合公差不符。2、紧定套与滚动轴承的锥度配合接触面不均。3、紧定套与滚动轴承在装配中的紧度不适。4、滚动轴承缺油、润滑脂变质硬化等。维修处理方法通常采用:1、堆焊复原法。其结果:堆焊过程中容易造成转轴变形,尤其是磨损位于中间,如果堆焊后退火处理不当,还会导
Rotor shaft wear, is a frequent mechanical failure, especially in bulky cots, roller, cage and other ends with a fixed sleeve bearing, more difficult to repair in the maintenance. The main reason for this type of mechanical failure is: 1, rolling bearing adapter sleeve and shaft with the tolerance does not match. 2, tight sets and rolling bearing taper with uneven contact surface. 3, tight sets and rolling bearings in the tightness of the assembly does not apply. 4, rolling bearing shortage of oil, grease hardening and so on. Maintenance methods are usually used: 1, surfacing recovery method. As a result: the process of surfacing easily lead to shaft deformation, especially wear in the middle, if the annealing after welding is not properly handled, but also guide
