Device for unloading shaft end bearing

Abstract

The invention discloses a device for unloading a shaft end bearing. The device comprises an oil cylinder and a round base. Clamping jaws are uniformly arranged at the periphery of the round base. Each clamping jaw is constituted by an L-shaped bent rod. Each clamping jaw is connected with the round base in a hinged manner. A piston rod of the oil cylinder is provided with a movable sleeving ring. Connecting rods are arranged on the movable sleeving ring. One end of each connecting rod is connected with the middle of the corresponding clamping jaw in a hinged manner, and the other end of each connecting rod is connected with the movable sleeving ring in a hinged manner. A fixed circular ring / disc is arranged at the top end of the piston rod. A compression spring is arranged between the movable sleeving ring and the fixed circular ring / disc. According to the bearing unloading device of the structure, the top end of the piston rod abuts against the shaft end of a rotating shaft; by means of the compression spring, all the clamping jaws are gathered together and folded; an inner ring of the bearing is pulled tightly through bent ends of the clamping jaws; the oil cylinder is started, the piston rod jacks, and the clamping jaws pull the bearing to move from the rotating shaft till the bearing completely breaks away from the rotating shaft; and rapid dismounting of the bearing is achieved.

Description

[0001] The present invention is a divisional application of an invention patent with an application date of September 9, 2014, an application number of 201410456396.0, and an invention title of "shaft end bearing unloading device". technical field [0002] The invention relates to the field of disassembly and maintenance of mechanical equipment, in particular to a device for unloading shaft end bearings. Background technique [0003] Bearings are often used in the installation of shafts or rollers in mechanical equipment. After long-term operation of mechanical equipment, the bearings are severely worn and need to be replaced, especially for mechanical equipment that requires high precision. When the traditional bearing is replaced, its operation is difficult, and workers need to use a hammer or other tools to continuously knock the bearing, so that the bearing is removed from the rotating shaft. This method is not only labor-intensive, but also the bearing is easily broken,...

AI Technical Summary

Problems solved by technology

When replacing traditional bearings, the operation is difficult, and workers need to use hammers or other tools to continuously tap the bearings to remove the bearings from the shaft

This method is not only labor-intensive, but also the bearing is easy to be broken, and the steel ring fragments are easy to cause damage when it pops up. At the same time, it will also cause bending deformation and surface damage of the shaft, which is not conducive to the replacement of bearings and the performance guarantee of mechanical equipment.
