Bearing, disassembling tool, and using method of disassembling tool

Abstract

The invention provides a bearing, a disassembling tool, and a using method of the disassembling tool, and belongs to the field of bearings and relevant hardware tools. The problem that a sealing ringof an existing bearing is not easy to disassemble is solved. The bearing comprises an inner ring, an outer ring, a retainer and steel balls, first annular sealing grooves are formed in the outer surface of the inner ring respectively and located on the two sides of the steel balls, and second annular sealing grooves are formed in the inner surface of the outer ring respectively and located on thetwo sides of the steel balls. The bearing further comprises an annular sealing ring, an inner reinforcing plate is arranged in the sealing ring, the surface of the inner reinforcing plate is perpendicular to the axis of the inner ring, and a plurality of rod-shaped pull rods positioned in the sealing ring are fixed on the inner reinforcing plate. A dismounting groove is formed in the outer end face of the sealing ring, an outer reinforcing plate is arranged in the disassembling groove, connecting holes are formed in the outer reinforcing plate, and the pull rods penetrate through the connecting holes and are connected with the outer reinforcing plate. Disassembling holes are formed in the walls of the pull rods, and the axis of each pull rod is parallel to the axis of the inner ring, and the axis of each disassembling hole is arranged in the radial direction of the inner ring. The strength of the bearing is higher, and meanwhile, the disassembling tool can reduce the disassembling difficulty of the sealing ring of the bearing.

Description

technical field [0001] The invention belongs to the technical field of bearings and related hardware tools, and relates to a bearing, a removal tool and a method for using the removal tool. Background technique [0002] The bearing seal is mainly to prevent the lubricant inside the bearing from leaking out, and to prevent external moisture, dust, foreign matter, etc. from entering the inside of the bearing, which in turn affects the operating performance and service life of the bearing. The existing patent number is ZL2016102443836, which is a Chinese invention patent named "a detachable deep groove ball bearing sealing structure". A pull rod with an internal thread groove at the end is installed on the top, and a dismantling device with an external thread is used to screw the internal thread groove at the end of the pull rod, and the sealing ring is pulled outward to separate the sealing ring from the bearing, and then lubricant can be added to the inside . However, the a...

AI Technical Summary

Problems solved by technology

[0003] 1. Since several pull rods are distributed and fixed on the sealing ring, and several pull rods are respectively connected to several dismantling devices, it is impossible to guarantee that several dismantling devices pull several pull rods with the same force at the same time, so the pull rod with greater force will be pulled out of the sealing ring first , resulting in bending and deformation of the sealing ring and the reinforcement plate;

[0004] 2. During the disassembly process, it is impossible to ensure that the disassembly device pulls the pull rod axially along the inner ring. Since the sealing ring, the inner ring and the outer ring will always rotate relative to each other, if force is applied in other directions, it will not only cause the sealing ring and the reinforcement plate to bend and deform, At the same time, it may also cause the tie rod to break, and the difficulty of unloading will also increase;

[0005] 3. Several dismantling devices need to be connected to the internal thread grooves of several pull rods one by one, resulting in low efficiency in connecting the pull rods to the dismantling devices;

[0006] 4. During the disassembly process, it is necessary to hold the bearing by hand and use the disassembly device to pull the pull rod, which is not only unhygienic, but also directly exerts force on the bearing with the hand, which may affect the bearing structure
