Detaching tool for bearing and use method of detaching tool

Abstract

The invention provides a detaching tool for a bearing and a use method of the detaching tool, and belongs to the field of bearing related hardware tools. The problem that a sealing ring of an existingbearing is not easily detached is solved. The detaching tool for the bearing comprises the bearing. The bearing comprises an inner ring, an outer ring, a sealing ring and a reinforcing plate. Multiple pull rods with internal thread grooves formed in the ends are fixed to the reinforcing plate. The detaching tool comprises a detaching rod and a detaching sleeve. A baffle ring is fixed to the wallof the detaching rod, an external thread is arranged on the portion, between the baffle ring and the front end of the detaching rod, of the wall of the detaching rod, and the diameter of the portion,between the baffle ring and the rear end of the detaching rod, of the detaching rod is identical to the internal diameter of the inner ring. A baffle is fixed to the outer wall of the front end of thedetaching sleeve, multiple penetrating holes are formed in the baffle, the detaching sleeve is movably screwed with the detaching rod, the rear end of the detaching rod penetrates through the inner ring, one side of the baffle ring abuts against one side of the inner ring, and the other side of the baffle ring abuts against the baffle. The detaching tool further comprises screws penetrating through the penetrating holes, the front ends of the screws are screwed to the internal thread grooves, and heads are arranged at the rear ends of the screws. By means of the detaching tool, the sealing ring on the bearing can be stably and efficiently detached.

Description

technical field [0001] The invention belongs to the technical field of hardware tools related to bearings, and relates to a dismantling tool for bearings and a using method thereof. 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 above-men...

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 reinforcing plate to bend and deform, At the same time, the difficulty of disassembly will increase, making the disassembly efficiency low;

[0005] 3. 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
