Brief introduction

Bearing lock is the bearing in the operation process to produce a lot of heat, but in a short time can not be dissipated in time, resulting in a sharp rise in bearing temperature, after all, bearing locking phenomenon, if not found and repaired in time, will affect the normal operation of the hammer crusher, and then affect its production efficiency. So what is the cause of the heavy hammer crusher bearing? How to fix it? This article will give you a detailed introduction.

First, the reasons for the bearing of the heavy hammer crusher

1. Assembly problems
   The bearing size is not measured and the inner hole is not trimmed during assembly, resulting in the bearing outer ring and the bearing seat hole or the bearing inner ring and the shaft are not matched. In this case, the machine will squeeze the outer ring of the bearing during operation, resulting in smaller radial clearance, uneven rolling of the rolling element, aggravating wear, generating a lot of heat, and eventually resulting in the bearing being locked. In addition, improper control of the bearing heating temperature will also lead to tempering, reducing hardness and accuracy, raising the bearing temperature and intensifying wear.
2. Oil seal problem
   Heavy hammer crusher is prone to produce a lot of dust pollutants during the working process, affecting the quality of the oil seal, resulting in dry friction and damage to the oil seal, so that the bearing temperature rise is too high in a short time.
3. Gap problem
   Improper adjustment of bearing clearance can also lead to bearing lock. If the axial clearance is too small, it will cause the bearing to heat; If the axial clearance is too large, it will increase the impact force of the moving pair, reduce the stiffness, and lead to abnormal sound and violent vibration.
4. Lubrication problems
   The grease in the bearing should not be too much, and the grease is too large, which will increase the friction torque and increase the bearing temperature. However, if the amount of grease is too small, it can not obtain reliable lubrication and dry friction occurs. Generally speaking, the appropriate amount of grease is 1/3 to 1/2 of the total void volume in the bearing. Therefore, in accordance with the requirements of use, the appropriate amount of grease should be injected regularly.

Second, the method to solve the bearing of the heavy hammer crusher
1, detailed inspection: in the assembly process or equipment inspection and repair, check the size of the bearing diameter and bearing seat hole and other parts to ensure that the size is consistent.
2, increase the support flexibility of the bearing seat: add the appropriate thickness of the rubber plate between the bearing seat and the support frame, improve the bearing support flexibility, reduce the impact load on the bearing.
3, ensure that the oil between the lips: to ensure the right amount of grease filling, avoid too much or too little, regularly check and replace the grease.
4, replace the oil seal: if there is a problem with the oil seal, the oil seal should be replaced in time and tested.
Through the above method, the problem of bearing lock of the heavy hammer crusher can be effectively solved to ensure the normal operation and production efficiency of the equipment.
