The installation of jiaxing bearing precision bearing

Jiaxing bearing group sales co. , LTD. , is the spot sales center of jiaxing bearing factory, specializing in HRB bearings, application in production design and related machinery has a wealth of technical experience, today we are together and we learn the installation of precision bearing. Precision bearing installation cooperates: in order to ensure that do not produce too large deformation of the bearings after installation, must do: ( 1) Shaft and hole of the roundness and block shoulder perpendicularity to according to the corresponding precision of bearing requirements. ( 2) Should not only precise calculation of rotating ring with the amount of interference, also to accurate calculation of the fixed ring with right quantity. The rotating ring burning interference quantity within may also should be made smaller. As long as to ensure that work under the temperature of thermal expansion effect, and under the maximum speed of centrifugal force effect, not cause peristalsis or sliding on the surface of the tight fit. Fixed ring according to the size of the working load and bearing size, choose the smallest clearance fit or interference fit, too loose or too tight is unfavorable to keeping the original precise shape. ( 3) Bearing such as under the condition of high speed operation and high working temperature, should pay special attention to the matching of the rotating ring is too loose, to prevent the eccentric vibration, and the matching of the fixed ring is a gap, in order to prevent the ferrule deformation and vibration under load. ( 4) Conditions for surplus with fixed circle take transgressions is suitable surface on both sides have high shape accuracy and smaller roughness, cause otherwise in installation and removal harder, in addition, also need to consider the influence of the spindle thermal elongation. ( 5) Using double angular contact ball bearing of the spindle in pairs, for the most part load lighter, its interference such as large amount, the amount of axial preload is its internal significantly larger, causing adverse effects. Using double row short cylindrical roller bearing of the spindle and spindle taper roller bearings, the load is opposite bigger, so its interference also relatively large.
