Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic torque converter manufacturing, and in particular relates to a bearing disassembly device for a hydraulic torque converter. Background Art

[0002] The turbine of the torque converter is mainly used for torque converter power output. In order to ensure the smooth rotation of the turbine, a bearing is installed on the turbine assembly. Since the internal space of the torque converter is very small, the bearing installation space is also very small. After the bearing is installed, it is difficult to disassemble when a problem is found and it needs to be disassembled. The existing technology uses a common bearing disassembly puller on the market to disassemble the bearing. Its disadvantages in use are that due to the small gap between the bottom of the bearing and the turbine assembly, the puller's claws are thin, low in strength, and cannot be centered, which can easily cause pulling and pulling, and the puller claws are easy to break. In order to ensure the intact disassembly of the bearing and improve work efficiency, an improved design is needed. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a bearing disassembly device for a hydraulic torque converter, so as to achieve complete disassembly of the bearing and improve work efficiency.

[0004] To achieve the above-mentioned purpose, the utility model provides a bearing disassembly device for a torque converter, comprising a three-jaw chuck, a pressure plate, a mounting bolt, an ejector bolt, an ejector block and an arc-shaped claw, wherein arc-shaped claws are respectively arranged below the three claws of the three-jaw chuck, and the ends of the arc-shaped claws are provided with inward arc-shaped bosses, and a pressure plate is arranged above the three-jaw chuck; the two ends of the pressure plate are fixed to the upper surface of the three-jaw chuck by mounting bolts, a threaded through hole is arranged in the center of the pressure plate, and the ejector bolt passes through the threaded through hole and downwardly enters the bottom of the three-jaw chuck; an ejector block is arranged at the lower end of the ejector bolt.

[0005] Furthermore, the arc-shaped jaws are welded below the three jaws of the three-jaw chuck.

[0006] By adopting the above technical scheme, the beneficial effect of the utility model is that the arc-shaped claw is inserted into the gap between the bottom of the bearing and the turbine assembly, the ejection block is pressed on the surface of the turbine assembly, and the ejection bolt is rotated to disassemble the bearing. The operation of the device is time-saving and labor-saving, and the work efficiency is improved without damaging the bearing. The arc-shaped claw is concentric with the bearing and will not move radially. The overall force is uniform and the arc-shaped claw has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0012] See also Figure 1 , Figure 2 , Figure 3 A bearing disassembly device for a torque converter comprises a three-jaw chuck 1, a mounting bolt 2, a pressure plate 3, an ejector bolt 4, an ejector block 401, an arc-shaped claw 5, a turbine assembly 6 and a bearing 7. Arc-shaped claws 5 are respectively arranged below the three claws 101 of the three-jaw chuck 1, and the ends of the arc-shaped claws 5 are provided with inward arc-shaped bosses 501. A pressure plate 3 is arranged above the three-jaw chuck 1; the two ends of the pressure plate 3 are fixed to the upper surface of the three-jaw chuck 1 by mounting bolts 2, a threaded through hole is arranged in the center of the pressure plate 3, and the ejector bolt 4 passes through the threaded through hole and downwardly enters the bottom of the three-jaw chuck 1; the lower end of the ejector bolt 4 is provided with an ejector block 401.

[0013] Furthermore, the arc-shaped jaws 5 are welded below the three jaws 101 of the three-jaw chuck 1 .

[0014] Working principle:

[0015] 1. First, rotate the three-jaw chuck 1 counterclockwise to drive the arc-shaped jaw 5 to move outward until the bearing 7 can enter the arc-shaped jaw 5;

[0016] 2. Then rotate the three-jaw chuck 1 clockwise so that the arc-shaped claw 5 locks the outer ring of the bearing 7, and the arc-shaped boss 501 clamps the lower end surface of the bearing 7;

[0017] 3. Rotate the ejector bolt 4 clockwise to eject the turbine assembly 6 through the ejector block 401 to separate it from the bearing 7;

[0018] 4. Release the arc-shaped claw 5 and remove the bearing 7 to complete the disassembly operation.
