The precision of the interference of non-standard bearing and the service life of the method

The precision of the interference of non-standard bearing and the method of service life of the source: bearing | last updated: - 2020 10 - 14 interference non-standard bearing precision and service life of the installation of automatic self-aligning ball bearing is appropriate, immediately interference precision, service life and bearing application features. ( 1) Clean up a lot of automatic self-aligning ball bearings, with temperature is 90 ~ 100 ℃ heat automobile engine oil pour hot make its encapsulated oil melting, in addition with seamless splicing hard mouth and exfoliation of net special tools to dig all the old oil, then pour hot for a few minutes, then clean with gasoline car engine oil, the final is mud in gasoline cleaning again. Clean up after cleaning, need to put on film gloves will automatic self-aligning ball bearing on the work table of dry clean cloth or paper. ( 2) Before automatic self-aligning ball bearing installation, should use appropriate measuring instruments in accordance with the requirements of technical standards on the design drawing, check the shaft and hole and its related parts production and processing quality ( Such as specifications, precision, appearance precision and roughness, etc. ) 。 ( 3) Open when installed in the automatic self-aligning ball bearing encapsulation, infiltration described it to handle the brisk pace of liquids such as motor gasoline in rotation, to ensure that the ball bearing, double twist and the raceway surface of the encapsulated oil was completely clean clean. Lubrication of non-standard bearings, grease the more the better? Lubrication of non-standard bearings, grease coating, the more the better, this is a common misconception. Too much oil in the bearing and the bearing can lead to excessive oil gathering, lead to high temperature. Rolling bearing lubricating oil quantity should be bearing internal 1/2 ~ 1/3 of the space, during high-speed operation can be reduced to one-third.
