【 HRB bearing common sense 】 Analyses the inner hole and shaft and the diameter and hole between cooperate

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Rolling bearing is a standard parts, so the bearing inner ring hole with the shaft with the use of hole system, ( Due to the bearing inner hole deviation adopts negative deviation, so the bearing inner hole and shaft with a more general matters similar cooperate in cylindrical tolerance) The bearing outer ring with a hole using the basic shaft system. Correct selection of bearing fit should guarantee the bearing function, prevent, outer ring and inner ring on the shaft hole relative rotation occur at work. Coordinates the consideration should be given the choice of the main factors are: (1) the type of load, rotating load-bearing ring ( General for the inner ring) Should choose a tight fit; Under fixed load ring ( Generally for outer ring) Can choose a loose fit; Under oscillating load ring can be used a little loose than rotary load. (2) the load size, the heavy load, the interference fit most should be. (3) the size of the bearing, with the increase of the bearing size, choose the interference fit of interference, the greater the clearance fit clearance. (4) working temperature, the bearing inner ring may be due to thermal expansion and shaft and loose, outer ring may be affected by thermal expansion of bearing axial winding. So you should think about the cooperate with the influence of the temperature rise and thermal conduction direction. (5) bearing rotating accuracy, when the rotation accuracy and operating stability requirements for bearing high, try to avoid using the clearance fit. 6. The convenience of installation and disassembly for the convenience of installation and removal, using clearance fit. 7) the displacement of the winding end bearing outer ring and hole clearance fit should be adopted, but cannot be too loose and rotate.
