Radial clearance adjustment method for Cylindrical Roller Bearing:
Cylindrical roller bearings Bearing NJ204E CYSD are available in a wide range of options. The Cylindrical Roller Bearing combined radial load on the load of the fixed load is exposed from the local ring raceway retaining ring and transmitted to the corresponding shaft or bearing. The characteristic of this load is that the radial load vectors are relatively static composites and rings. Bear the load ring, you can use relatively loose.
Cylindrical Roller Bearing Rotary load is a full complement cylindrical roller bearing ring acting on a synthetic radial load acting on a drum rotating in a circumferential direction, rotating each part such as the load of rotation, which is rotated by the radial load of the composite vector phase loop, bearing . Bearing NJ204E CYSD The rotating load ring is closely fitted, in special cases, the load, such as the elected, is light or heavy under low speed load, only occasionally rings, the bearing is made of hard material and the surface roughness is high, the rotating load bearing ring can also be Used to be looser.
Cylindrical Roller Bearing The third load swinging load or non-directional load, the combined direction of the radial load of the load ring is uncertain, it is characterized by the role of the synthetic ring radial load vector ring raceway, in a certain area within the impact load, vibration, The load, its direction is swinging, the roller has to bear a certain area, or the load on the bearing, the load value often changes. To bear the weight swing, the outer ring and the outer ring, the bearing and the hole should be used in close cooperation.
The common method of adjusting the radial clearance of a full complement cylindrical roller bearing is as follows:
1. The backlash of cylindrical and elliptical bearings can be adjusted by hand-scraping or by lapping in the bearing after lapping.
2. For the top clearance of cylindrical and elliptical bearings, the method can be adjusted by means of hand-scraping or when the situation permits.
3. For multiple oil wedge fixed bearing bushes, it is in principle not allowed to shave and adjust bearing gaps. Replace the new ones if the clearance is not appropriate.
4. For multi-oil wedge tilting bearing bushes, it is not allowed to repair the brake pads. If the clearance is not suitable, replace the pads. For tiles with adjustable thickness, the wattage can be adjusted by adding a stainless steel pad underneath the tile adjustment block or by thinning the adjustment block thickness. Note that for multiple oil wedge tilting bearings, the thickness difference between the same group of tiles should be less than 0.01mm.
