轴承座孔严重磨损后,轴承的外圆就会和座孔产生相对转动,这种故障俗称“走外圆”。常见的修理方法是: 1.拉毛修理法这种方法多在轴承座孔磨损不大时采用。将轴承放在电焊机搭线上,用焊钳夹一根废锯条,接通电源,使锯条与轴承外圆接触,在轴承外圆表面拉出一层麻点后,即可装配使用。操作时应注意,麻点要细密均匀,轴承温度不能超过100℃。 After the bearing seat hole is severely worn, the outer circumference of the bearing will rotate relative to the seat hole, which is commonly known as “running outside”. Common repair methods are: 1. Brushed repair method This method is used in the bearing seat hole wear less. The bearing on the welding machine take the line, with a clamp clamp a waste sawn, turn on the power, the saw blade and the bearing outer circle contact, the outer surface of the bearing pull out a layer of pits, you can assemble use. Should pay attention to the operation, pitting should be fine and uniform, the bearing temperature can not exceed 100 ℃.
