The clearance of the rolling bearing is usually divided into the original clearance, the device clearance and the application clearance. The original clearance is also called the production clearance; it is produced by the bearing manufacturer according to the national or industry standard requirements based on different bearing types. The bearing clearance selected by the organizer at the end is also the clearance. The bearing is in the process of the device; because the inner ring and the shaft, the outer ring and the bearing hole have different degrees of interference devices; the clearance behind the bearing device will be based on When the device is installed, the amount of interference of the shaft and the hole is changed; the interference is large when the device is installed; the clearance after the bearing device is changed. å²¢.å²¢é‚ªæ²§æ²§èŸ®èŸ®ä¾—æµ ä¾—æµ å†‰å†‰å†‰ä¼²ä¼²If it is a corner touch bearing; the device can be used with a pre-interference device; the bearing has no play behind the device; perhaps a negative play. The pre-interference device can improve the rigidity of the bearing and The accuracy of the reversal of the organization is also improved. The bearing is in the process of use; because the conflict generates heat; the clearance of the bearing will be smaller than the clearance after the device; so the original clearance of the bearing must be greater than the use of the clearance. Of course To make the diameter of the bearing The gap is changed. The tip of the arm and the worm, the worm, the cymbal, the cymbal, the cymbal, the 1 set, the 2 sets of clearance, and perhaps the interference between the bearing and the shaft and the hole (excessive interference) It will make the bearing device very difficult; it may also cause the bearing ring to rise.) The rotation speed of the bearing is determined by the type, layout, precision and smoothing method of the bearing; it has little to do with the clearance of the bearing.
