Description

Technical Field

[0001] The utility model relates to the field of bearing removal, in particular to a bearing remover. Background Art

[0002] The main function of bearings is to support rotating shafts and reduce friction to ensure smooth operation of equipment. However, over long-term use, bearings may need to be replaced or repaired due to wear, fatigue or damage.

[0003] Current bearing removal methods often rely on hand tools. Some specialized bearing removal tools often have disadvantages such as single function and poor adaptability. The bearing sleeve is connected to the outer wall of the shaft, and some tools can only remove specific types of bearings. In other words, the bearing will be at different positions on the shaft, and the bearing removal tools cannot remove bearings at different positions or bearings of different sizes. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a bearing remover.

[0005] The technical solution adopted by this utility model:

[0006] The top of the two lever is connected with the up-down knob of the lifting link, and the limit of each pin is connected with the up-down knob of the lifting link, and the limit of each pin is connected with the up-down knob of the lifting link.

[0007] The opposite ends of the two splints are concave in an arc shape.

[0008] Beneficial effects of the utility model:

[0009] The utility model can adapt to bearings of different lengths by adjusting the distance between the upper threaded rod and the lower threaded rod. The distance between the two clamping plates can be conveniently adjusted through the sliding groove, so that bearings of different diameters can be removed, thereby increasing its practicality and flexibility.

DETAILED DESCRIPTION

[0014] like Figure 1-3 As shown: A bearing remover, including a cross bar 1, a push rod 2 running through the middle of the cross bar 1, the middle of the cross bar 1 and the push rod 2 are threadedly connected, the push rod 2 extends up and down, the bottom end of the push rod 2 is fixedly connected with a head 3, the top of the push rod 2 is vertically fixedly connected with a rotating handle 4, the top of the cross bar 1 is provided with two slide grooves 5, the two slide grooves 5 are symmetrically distributed on the left and right sides of the push rod 2, the tops of the two upper threaded rods 6 are respectively in the two slide grooves 5, the tops of the upper threaded rods 6 are slidably matched with the slide grooves 5, and the top screws of the upper threaded rods 6 are screwed in The threads are connected with a fixing nut 7, which is tightly pressed against the top of the cross bar 1. A lower threaded rod 11 is provided below the upper threaded rod 6. The thread directions of the upper threaded rod 6 and the lower threaded rod 11 are opposite. The outer walls of the upper threaded rod 6 and the lower threaded rod 11 are respectively threadedly connected with an upper collar 8 and a lower collar 10. Two symmetrically distributed connecting rods 9 are fixedly connected between the outer walls of the upper collar 8 and the lower collar 10. The bottom end of the lower threaded rod 11 is fixedly connected with a pull rod 12, and the bottom end of the pull rod 12 is fixedly connected with a splint 13.

[0015] The opposite ends of the two clamping plates 13 are arc-shaped and concave.

[0016] The arc-shaped concave design of the clamping plate 13 helps to maintain a stable clamping of the bearing during the removal process, preventing the bearing from slipping or being damaged during the removal process.

[0017] First, align the arc-shaped concave part of the splint 13 with the outer wall of the bearing to be removed, and the arc-shaped concave part of the splint 13 fits with the shaft where the bearing to be removed is located. According to the position and length of the shaft where the bearing to be removed is located, adjust the position of the upper ring 8 and the lower ring 10 by rotating the connecting rod 9.

[0018] Since the thread directions of the upper threaded rod 6 and the lower threaded rod 11 are opposite, moving the connecting rod 9 will cause the upper threaded rod 6 and the lower threaded rod 11 to move toward or away from each other, thereby adjusting the distance between them.

[0019] The upper threaded rod 6 moves along the sliding groove 5 to adjust the distance between the two clamping plates 13 until the clamping plates 13 can tightly clamp the side walls of the bearing.

[0020] After adjusting the spacing, tighten the fixing nut 7 to ensure that the upper threaded rod 6 is fixed to the slide groove 5 at the top of the cross bar 1 to prevent movement during the removal process.

[0021] The push rod 2 is rotated by rotating the handle 4 so that the push head 3 gradually presses against the end of the shaft.

[0022] As the push rod 2 rises, the bearing is gradually pushed out of its installation position until it is completely disengaged.
