Guangzhou yunfu bearing manufacturer to probe into the inner hole and outside diameter hole to cooperate

Guangzhou yunfu bearing manufacturer to probe into the inner hole and outside diameter hole with rolling bearings are standard parts, so the bearing inner ring hole with the shaft with the use of hole system, ( Due to the bearing inner hole to the negative bias, so the bearing inner hole and shaft with a common cylindrical tolerance in much similar with matters) The bearing outer ring with a hole using the basic shaft system. Correct selection of bearing fit should guarantee the normal operation of high temperature bearing, avoid, outer ring and inner ring on the shaft hole relative rotation during the course of work. Cooperate with choice should think about the main elements are: (1) the type of load, accept the slewing ring load ( Common for the inner ring) Should choose a tight fit; Accept the ring of fixed load ( Common for outer ring) Can choose a loose fit; Accept the oscillating load ring with a little loose than rotary load can be used. (2) the load, the size of the load weight, should cooperate with interference. (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 contraction and shaft and loose, outer ring may be affected due to thermal contraction of bearing axial winding. So should be consider the influence of temperature rise and thermal conduction direction to cooperate. (5) bearing rotating accuracy, when the bearing rotating accuracy and operating stability request high, as far as possible to prevent the clearance fit. 6 the device and remove the lunch and for lunch device and remove, with the 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.
