Hydraulic drive detaching device of bearing

Abstract

The invention discloses a hydraulic drive detaching device of a bearing. The device is mainly characterized in that a round boss which is of an integrated structure and upwards protrudes is arranged on the center of a round top plate, being of the integrated structure, of the upper end of a detaching head, a limiting cylinder which is of an integrated structure and protrudes upwards is arranged onthe center of the round boss, guide holes are formed in the centers of the limiting cylinder, the round boss and the round top plate, hydraulic drive piston rods which is used for ejecting a bearingwhen the bearing on a bearing position shaft neck on the upper end of a transmission shaft are arranged in the guide holes, the lower end of the detaching head is provided with a round bottom plate which is of the integrated structure and used for ejecting the bearing when the bearing is detached, the left end of the round bottom plate is provided with a lower opening groove used for transferringthe transmission shaft into the center of the round bottom plate when the bearing is detached, the lower left end of the cylinder wall of the detaching head is provided with a measuring opening groovefor moving the bearing into the inner hollow center of the dismounting head when the bearing is detached, the worn bearing on the bearing position shaft neck on the upper end of the transmission shaft can be simply, easily and rapidly detached, labor intensity is reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bearing removal tools, in particular to a hydraulic removal device for bearings. Background technique [0002] In the maintenance of mechanical equipment, the worn bearings must be replaced. When replacing bearings, professional maintenance manufacturers use hydraulic presses to press the worn bearings from the bearing journal of the transmission shaft, and then use hydraulic presses to press new bearings. Install it back on the bearing journal of the transmission shaft. However, the general manufacturers do not have the conditions for professional maintenance manufacturers. When replacing the bearings, they can only use three claws to lift the worn bearing from the bearing journal of the transmission shaft. When the three claws are used to eject the worn bearing on the bearing journal of the transmission shaft, there is a problem that the three claws are not easy to be stuck on one end face of the inner ...

AI Technical Summary

Problems solved by technology

[0002] In the maintenance of mechanical equipment, the worn bearings must be replaced. When replacing bearings, professional maintenance manufacturers use hydraulic presses to press the worn bearings from the bearing journal of the transmission shaft, and then use hydraulic presses to press new bearings. Install it back on the bearing journal of the transmission shaft. However, the general manufacturers do not have the conditions for professional maintenance manufacturers. When replacing the bearings, they can only use three claws to lift the worn bearing from the bearing journal of the transmission shaft. When the three claws are used to eject the worn bearing on the bearing journal of the transmission shaft, there is a problem that the three claws are not easy to be stuck on one end face of the inner ring of the worn bearing at the same time. The worn bearings on the bearing journal of the transmission shaft are not only cumbersome and laborious to operate, but also slow in speed and low in work efficiency

[0003] The bearing puller combined with a jack and three claws on the market also has the problem that the three claws are not easy to be stuck on one end face of the inner ring of the worn bearing at the same time, and there is a problem of troublesome operation. At the same time, there are problems when shaking the operating handle of the jack. The problem of labor is that using a jack and three-jaw bearing remover to remove the worn bearing on the bearing journal of the transmission shaft also has the problems of troublesome operation, laborious, slow speed and low work efficiency
