Bearing dismantling device

Abstract

The invention relates to a bearing dismantling device, comprising a pull rod, a press ring and a regulating pad; the press ring is fixedly arranged in the dismantling direction of a bearing outer ring, the end surface of the press ring is matched with the that of a part provided with a bearing bush, a step arranged on the press ring is matched with the end surface of the bearing bush, the pull rod is in clearance fit with the bottom of the press ring, a disc is arranged at one end of the pull rod, the end surface of the disc is in contact with the end surface of the bearing outer ring and can move toward the dismantling direction along with the pull rod. The axial limiting of the bearing bush and the part provided with the bush during the disassembling of the bearing outer ring is realized, the bearing bush is prevented from being separated under the action of a disassembling force, the use safety is ensured, unnecessary repair or cost loss caused by replacement of a new product is reduced, and the production period is shortened.

Description

technical field [0001] The invention relates to a dismantling device, in particular to a bearing dismantling device. Background technique [0002] Bearings are widely used rotating components in mechanical transmission, and are generally installed between the shaft and the bearing bush on the casing. For tapered roller bearings, an interference fit is used between the outer ring and the bearing bush on the casing during design. Since the inner and outer rings of the tapered roller bearing can be separated, the inner ring is separated with the shaft when disassembled, and the outer ring remains in the machine. In the mounting hole of the bearing bush on the box, it is necessary to apply force on the end face of the outer ring of the bearing for separate decomposition. Since the outer ring of the bearing and the bush are in an interference fit, it is easy to drive the bush during the force application process, thereby deviating from the Its correct installation position excee...

Problems solved by technology

For tapered roller bearings, an interference fit is used between the outer ring and the bearing bush on the casing during design. Since the inner and outer rings of the tapered roller bearing can be disassembled, the inner ring is separated with the shaft when disassembled, and the outer ring remains in the machine. In the mounting hole of the bearing bush on the box, it is necessary to apply force on the end face of the outer ring of the bearing to disassemble it separately. Since the outer ring of the bearing and the bush are in an interference fit, it is easy to drive the bush during the force application process, thereby deviating from the Its correct installation position exceeds the design requirements

For devices that require continuous use, abnormal bearings and large vibrations are likely to occur during continuous use, which will affect the safety of use. Repairing or replacing new products will increase the cost and prolong the production cycle, resulting in unnecessary waste of resources.
