The importance of bearing inner ring is installed

Bearing inner ring is installed the Importance of the Importance of the Proper Fits inside is installed under the condition of rolling bearings for roller bearing only slight disturbance, harmful may occur between internal circular sliding ring and shaft. Inner ring of the slide, this is known as' creep ', if lead to circular ring relative to the axis displacement interference fit tight enough. Creep occurs, the surface of assembly become wear, lead to wear and considerable damage to the shaft. Also may be due to abnormal heat and vibration grinding and went into the inner bearing metal particles. There is enough to prevent the creep are the important interference firmly fixed rotating ring shaft and shell. Creep does not always eliminate the tighten bearing ring by axial surface only. In general, it is not necessary, however, in order to offer ring by ring interference is limited to a fixed load. Sometimes ready to cooperate with internal and external ring has any interference, so as to adapt to certain operating conditions, or with convenient installation and disassembly. In this case, prevent due to creep damages to the fitting surface, other applicable methods of lubrication should be considered. The importance of bearing inner ring installation: to select suitable ( 1) Can load condition and the adaptation from table 9. 1 select the correct fitting load and operating conditions. （ 2) Load interference and disturbance variable inner ring slightly reducing the bearing load; Therefore, the loss of the interference interference should be estimated using the following equation. But, in the case of heavy load, radial load by more than 20% of the basic C 0 r rated static load under the condition of the business, often interfere with shorter.
