Description
Technical Field
The invention relates to a disassembling tool, in particular to a novel cylindrical roller disassembling device
Background
At present, in some bearing application fields with higher precision requirements, a simulation installation test is carried out on a bearing before formal installation so as to know whether the bearing can meet working conditions. Therefore, the roller needs to be frequently disassembled to observe the working conditions of the bearing raceway and the retaining edge so as to know whether the bearing operates normally or not in time. Meanwhile, in some industries, the bearing needs to be periodically disassembled to repair the raceway and the roller. Therefore, a simple roller dismounting device is urgently needed.
Disclosure of Invention
The invention aims to provide a novel cylindrical roller dismounting device.
The technical solution of the invention is as follows: the utility model provides a novel cylindrical roller dismantles device comprises two threaded rods, removal holder, fixed holder, nut and dismantlement lever, its characterized in that: one end of the two threaded rods is fixedly connected with the rear part of the fixed clamp holder through threads, the other end of the two threaded rods penetrates through the through hole in the rear part of the movable clamp holder and is provided with a nut on the outer side, the middle part of the other threaded rod is provided with a dismounting lever, the two ends of the other threaded rod respectively penetrate through the threaded through holes in the middle front parts of the fixed clamp holder and the movable clamp holder, and the nut is arranged on the.
Compared with the prior art, the invention has the advantages of no damage to the roller when the roller is disassembled, time and labor saving and the like.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present invention
FIG. 2 is a schematic diagram of the usage status of the embodiment of the present invention
In the figure: 1. the bearing comprises a threaded rod, 2, a nut, 3, a movable clamp, 4, a disassembly lever, 5, a fixed clamp, 6, a bearing roller, 7, a bearing inner ring, 8 and a bearing retainer.
Detailed Description
The embodiments are described below with reference to the accompanying drawings:
the invention is assembled by two threaded rods 1, a movable clamp 2, a fixed clamp 5, a nut 3 and a disassembly lever 4 according to the attached drawing 1. The dismounting device is suitable for a cylindrical roller bearing with a locking point on the outer diameter of a bearing retainer 8, does not damage the bearing roller 6, the bearing retainer 7 and the raceway of the bearing inner ring 7 in the dismounting process, and is a simple, convenient and quick dismounting device. Particularly, for the bearing used on the testing machine, the running states of the bearing roller, the raceway and the like can be repeatedly observed in stages, and technicians can know the test conditions in time. Meanwhile, the invention can also be applied to the field of bearing repair.
The invention utilizes the lever principle to place a bearing horizontally, a fixed clamp 5 is horizontally contacted with the bottom of a bearing roller 6, then a movable clamp 3 is slowly lowered through a threaded rod 1 until being contacted with the upper end surface of the bearing roller 6, and is locked through a nut 2, the upper clamp and the lower clamp are held by the last hand, a disassembly lever 4 is held by the other hand, the disassembly lever is contacted with the bearing roller 6, and then the roller comes out with force.
