Description

Technical Field

[0001] The utility model relates to the field of bearing inspection and maintenance equipment, in particular to a bearing disassembly tool. Background Art

[0002] After a period of use or when new equipment arrives, bearings require cleaning, maintenance, and oil changes. Traditionally, the cleaning method involved removing the bearings and placing them directly in a container with bearing cleaner. However, deep grooves in the bearings are difficult to reach with a brush, leaving residual oil that can impact the bearing's lifespan. Cleaning these deep grooves requires a large amount of bearing cleaner, which wastes both human resources and material costs. To thoroughly clean the bearings, the bearings must be disassembled and the balls removed, allowing brushes to reach the deep oil deposits. First, the ball retainer is removed, the balls are aligned, and a screwdriver is used to pry one side up, dislocating the inner and outer races and releasing the balls. This method not only tests the operator's skill but can also damage the bearings with even the slightest care, shortening their service life. Consequently, bearing disassembly and cleaning has always been a complex, labor-intensive, and time-consuming process, with the bearings susceptible to damage during disassembly. Existing bearing disassembly tools vary in structure, each with varying degrees of complexity and inconvenience in handling and movement. Utility Model Content

DETAILED DESCRIPTION

[0013] The following describes in detail the technical solution of an embodiment of the present invention in conjunction with the accompanying drawings, so as to make a clearer and more complete description of the protection scope of the present invention. Obviously, the embodiment described is only one embodiment of the present invention, not all.

[0014] Referring to the embodiment shown in the accompanying drawings, the utility model is a bearing disassembly tool, comprising a fixer, a connecting rod and a jack structure, wherein the fixer structure comprises a fixed plate 101, three groups of transverse limiters 102 and a longitudinal limiter 103 installed in the fixed plate 101; the fixer structure is fixedly connected to the connecting rod structure by welding the fixed plate 101; each group of transverse limiters 102 comprises a transverse limiter rod 104, and each group of longitudinal limiters 103 comprises a longitudinal limiter base 109; one end of the transverse limiter rod 104 passes through the wall hole on the fixed plate 101 and is welded and fixedly connected to the longitudinal limiter base 109, and the transverse limiter rod 104 is slidably connected in the wall hole of the fixed plate 101; the jack structure is placed below the fixer structure, and a chassis 301 is provided on the bottom surface of the jack structure, which is welded and fixedly connected to the connecting rod structure, and a force transmission rod 304 is provided on the top of the jack 302.

[0015] The transverse limiting rod 104 is provided with a transverse adjusting nut A 105 and a transverse adjusting nut B 106 which are threadedly connected. The transverse adjusting nut A 105 is located on the inner side of the fixed plate 101 , and the transverse adjusting nut B 106 is located on the outer side of the fixed plate 101 .

[0016] The longitudinal limiter 103 consists of a longitudinal limiter rod 107, a longitudinal adjustment nut C108, and a longitudinal limiter base 109, wherein the longitudinal adjustment nut C108 is welded and fixedly connected to the longitudinal limiter base 109. The longitudinal limiter base 109 is provided with a base hole opposite to the screw hole of the longitudinal adjustment nut C108. One end of the longitudinal limiter rod 107 is threadedly connected to the longitudinal adjustment nut C108.

[0017] A supporting cover 303 is provided on the top of the jack 302 of this embodiment, and the supporting cover 303 is vertically welded and fixedly connected to the force transmission rod 304 .

[0018] The force transmission rod 304 of this embodiment is a thin rod that can precisely contact the inner ring of the bearing.

[0019] The connecting rod structure of this embodiment is composed of three equal-length tubes 201 divided into equilateral circles.

[0020] When using the present invention, the transverse limit rod 104 and the longitudinal limit rod 107 are adjusted, and the three sets of transverse limiters 102 and longitudinal limiters 103 are adjusted to their widest and highest points. The bearing to be disassembled is placed in the three sets of longitudinal limiter bases 109. At the same time, the transverse adjustment nuts A 105 and B 106 threaded on the three transverse limit rods 104 are adjusted to clamp the bearing to be disassembled. The transverse adjustment nuts A 105 and B 106 are tightened to fix the transverse limit rod 104 so that the bearing is located in the center of the fixture structure. The three longitudinal limit rods 107 are then adjusted to compress the bearing longitudinally. At this time, the jack 302 is raised, the rotating support cover 303 is moved, and the force transmission rod 304 is aligned with the part of the bearing inner ring without the bearing ball. An upward force is applied to the bearing inner ring, and the fixture structure now forms a reaction force on the bearing outer ring. Under the premise of continuously applying force, the inner ring of the bearing is tilted to form a large angle with the outer ring of the bearing. The bearing balls are squeezed out of the bearing under the condition of mutual compression, so that the bearing can be disassembled easily.

[0021] The purpose of setting the transverse limiter is to enable transverse adjustment according to the size of the bearing. The purpose of welding the longitudinal limiter 103 to the transverse limiter 102 is to enable longitudinal adjustment according to the thickness of the bearing. In this way, effective adjustment can be made according to different models and sizes, which is convenient for the fixer to fix the bearing.

[0022] The jack structure welds a chassis 301 to a connecting rod structure, with the jack 302 placed on the chassis 301 for easy removal and movement. A support cap 303 is located on top of the jack 302, and a force transmission rod 304 is welded perpendicularly to the support cap 303. To disassemble the bearing, align the force transmission rod with the inner race of the bearing and press the jack 302, which dislocates the inner and outer races, allowing the bearing balls to be removed and the entire bearing to be disassembled.

[0023] The connecting rod structure is composed of three equal-length tubes 201, which are divided into equilateral circles. The purpose is to connect the fixer structure and the jack structure. At the same time, the equilateral circles make it balanced and can be placed horizontally on the ground, serving as a handle for easy handling when moving.

[0024] The above description is only one embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structure or equivalent transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the scope of patent protection of the present invention.
