We often encounter in the use of the process such as these cases is how to form, has been the biggest headache of the technical staff of the major companies, what is the solution when forming the following points the more mechanical bearings in use Causes and solutions in overheating phenomenon is detailed:
Instantaneous temperature can make the surface of the grinding zone of a certain depth (10 ~ 100nm) is heated to a temperature higher than the workpiece tempering heating. The austenitizing temperature is not reached, with the increase in temperature is heated, the surface layer by layer will be generated corresponding to the heating temperature retempered or tempering organizational changes, the hardness decreases. The higher the heating temperature, the hardness of the decline is also more powerful.
1, bearing maintenance: cleaning of the bearing: Removing the lower bearing maintenance, the appearance of the first record bearing, to confirm the residual amount of the lubricant, the sample check of the lubricant used, wash the bearings. As a cleaning agent, ordinary gasoline, kerosene. The removed bearing cleaning, cleaning and fine cleaning sub-coarse, were placed in the container, first put the metal bottom of the network, bearing no direct contact with the container dirt. The rough cleaning the bearing with dirt rotation, will damage the bearing rolling surface, it should be noted. Rough cleaning oil, use a brush to remove to grease, adhesive material, generally clean, transferred to sperm washing.
2, bearing maintenance required: in good condition for as long as possible to maintain bearing the original performance, maintenance, overhaul, order to prevent accidents in the first place, to ensure the reliability of operation, improve the productive economy. Operating standards, maintenance of the best corresponding mechanical operation conditions on a regular basis. The content includes monitoring the operation state, to supplement or replace the lubricant periodic disassembly inspection. Maintenance matters, in the operation of the rotation of the bearing sound, vibration, temperature, lubricant status, etc..
3, bearing overhaul and judgment: In order to determine whether the removed bearing can be used to check bearing wash. Check raceway, rolling surface, with the surface state, cage wear, increased bearing clearance and damage decreased unrelated dimensional accuracy exception. Non-separable type of small ball bearings, the inner ring with one hand and the level of support the rotating outer ring to confirm whether smooth. Sperm washing, cleaning oil bearing while rotating, while carefully cleaning. In addition, cleaning the oil should be kept clean.
