为什么了解轴承清除变得如此重要

轴承间隙也称为轴承清除。当轴承未安装在轴或轴承盒中时,它将是其固定的内环或外环,然后在侧面进行径向或轴向运动时,不固定。

轴承内部间隙是指相对于总距离(径向内部清除率)或轴向运动(轴向内部清除)的另一个轴承圆径向运动的轴承圆。

轴承间隙

1,所谓的轴承间隙,即,当轴承未安装在轴或轴承盒中时,其侧面的内环或外环是固定的,然后不固定侧面进行径向或轴向运动当运动量时。根据运动的方向,可以将其分为径向间隙和轴向间隙。
  2, Running clearance (called work clearance), the size of the bearing rolling fatigue life, temperature rise, noise, vibration and other performance has an impact.
  3, Measurement of bearing clearance, to get stable measurement value, generally on the bearing to apply the specified measurement load. Therefore, the measurement value obtained from the actual clearance (called theoretical clearance) is significant, increasing the amount of elastic deformation generated by the measurement load. For roller bearings, because the elastic deformation is small, it can be neglected.
  4, The internal clearance of the bearing before the theoretical clearance generally expresses installation.
  5, From the theoretical clearance minus bearing installed in the shaft or shell because of interference with the collar expansion or contraction of the clearance called “installation clearance”. The installation clearance plus or minus the bearing internal temperature difference generated by the amount of dimensional change after the clearance is called “effective clearance”.
  6, Bearing installation has mechanical bearing a specific load placed clearance, that is, adequate clearance plus bearing load generated after the amount of elastic deformation so-called “work clearance”.
  7, When the work clearance for micro-negative value, bearing fatigue life is the longest, but with the increase of negative clearance, fatigue life significantly declines. Therefore, choosing the bearing clearance, generally making the work clearance zero or slightly vivacious, is appropriate. In addition, need to improve the rigidity of the bearing or need to reduce the noise, work clearance to take the negative value further, and in the bearing temperature rise is intense, work clearance is to take the positive value further, etc., also must be used according to the conditions to do specific analysis.
