The disassembly method of cone hole and cylinder hole of rolling mill bearing and the function requirement of retainer are briefly analyzed


A: the pressure oil feeding disassembly method of taper mill bearing


Take apart the relatively small imported rolling mill bearing with tight set, support the inner ring with the gear block fastened on the shaft, turn the nut back several times, and knock it open with a hammer using the pad block. Large rolling mill bearings, the use of oil pressure to open more simple, in the cone hole shaft in the oil hole under pressure to send oil, make the inner ring swell, open the imported rolling mill bearings. In operation, there are rolling mill bearings suddenly out of perhaps, it is better to use the nut as a block.


Two: Pull out and disassemble method of cylindrical hole rolling mill bearing


The inner ring of rolling mill bearing can be disassembled by pressure machinery. At this moment, we should pay attention to let the inner ring accept its pulling force.


The functional requirements of rolling mill bearing cage material are mainly as follows:


1. Small friction coefficient with tumbling body, good wear resistance function;


2. Because the cage structure is generally complex, the data used are required to have outstanding processing function;


3. With a certain strength and toughness, the cage can accept a certain load and impact, has better elasticity and stiffness;


4. Must have excellent thermal conductivity function;


5. The bearing cage is required to have excellent injection molding function.


6. The vehicle cage data require that the bearing cage has excellent cutting function;


7. The data of die casting cage should have excellent casting function;


8. The specific gravity is small and has a swelling coefficient similar to that of the tumbling body;


9. The stamping molding cage information requires that the bearing cage has outstanding plasticity and ductility.
