Description

Technical Field

[0001] The utility model relates to the technical field of speed reducer bearing assembly and disassembly, and more specifically, to an integrated tool for press-assembling and disassembling a rotary speed reducer bearing. Background Art

[0002] A reducer matches speed and transmits torque between the prime mover and the working machine or actuator. A reducer is a relatively precise machine used to reduce speed and increase torque. A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is commonly used as a reduction gear between the prime mover and the working machine.

[0003] When installing and removing the reducer bearing, it is necessary to first remove the reducer cover, and then take out the gear set inside the reducer. Then the bearing on the gear shaft can be removed, or the bearing can be press-fitted onto the gear shaft. In this process, the gear shaft needs to be fixed, and the existing gear shaft fixing method is generally to clamp and fix the gear shaft through two sets of clamping blocks. Since the outer side of the gear shaft is relatively smooth, the fixing effect of the gear shaft is not firm. When installing and removing the bearing, it is easy to cause the gear shaft to shift, making it inconvenient to install and remove the bearing.

[0004] In view of this, we propose an integrated tooling for press-fitting and disassembling the bearings of a rotary reducer. Utility Model Content

[0027] A rotary reducer bearing press assembly and disassembly integrated tooling, comprising a fixing frame 1, a mounting frame 2 is fixedly provided on the upper side of the fixing frame 1, a first electric push rod 3 is provided under the mounting frame 2, one end of the first electric push rod 3 is connected to the mounting frame 2, and the other end of the first electric push rod 3 is provided with a mounting block 4, a limit plate 5 is movably provided on the lower side of the mounting block 4, a first positioning plate 9 is provided on the outer side of the limit plate 5, and a fixing block 14 is fixed on the upper side of the mounting block 4, a second electric push rod 15 is provided on the outer side of the fixing block 14, and one end of the second electric push rod 15 is connected to the mounting frame 2. It is connected to the fixed block 14, and the other end of the second electric push rod 15 is provided with a fixed rod 16, the outer end of the fixed rod 16 is fixedly provided with a second positioning plate 17, and a hydraulic cylinder 18 is provided on the inside of the fixed frame 1. The power end of the hydraulic cylinder 18 is fixedly provided with a support rod 19, and the outer end of the support rod 19 is fixedly provided with a bearing push ring 20. By arranging the first positioning plate 9 and the second positioning plate 17, the two ends of the gear shaft can be easily supported, so that when the bearing is pressed or disassembled, the stability of the gear shaft is guaranteed and the gear shaft is prevented from moving.

[0028] Specifically, a fixing cylinder 6 is fixedly provided on the outside of the limit plate 5, and a threaded rod 7 is movably inserted into the inside of the fixing cylinder 6. The threaded rod 7 passes through the fixing cylinder 6 and extends to the outside, and the outer end of the threaded rod 7 is located on the outer part of the fixing cylinder 6 and is fixedly provided with a connecting rod 8. The connecting rod 8 is fixedly connected to the first positioning plate 9. The position of the positioning plate 9 can be easily adjusted so that it can be used for gear shafts of different lengths, and has better applicability.

[0029] Furthermore, a turntable 10 is rotatably provided on the outside of the fixed cylinder 6, and a threaded ring 11 is fixedly provided on the inside of the turntable 10. The threaded ring 11 is threadedly connected to the threaded rod 7. Through the threaded connection relationship between the threaded ring 11 and the threaded rod 7, the threaded rod 7 can be fixed, thereby improving the installation stability of the threaded rod 7, thereby ensuring the stability of use of the first positioning plate 9.

[0030] It is worth mentioning that a plurality of anti-skid grooves are provided on the outside of the turntable 10 . The anti-skid grooves can improve the friction of the turntable 10 , making the rotation of the turntable 10 more convenient.

[0031] It is worth noting that a square block 12 is fixedly provided on the inner side of the fixed cylinder 6, and a square groove 13 for docking with the square block 12 is penetrated on the inner side of the threaded rod 7. When the turntable 10 is rotated, the threaded rod 7 can be driven to rotate. Since the threaded rod 7 is limited by the square block 12 at this time, the threaded rod 7 cannot rotate, but will move parallel to the square block 12, thereby facilitating the movement of the connecting rod 8 and the first positioning disk 9.

[0032] In addition, a threaded rod 21 is rotatably provided on the upper side of the limit plate 5. The thread of the threaded rod 21 passes through the mounting block 4 and extends to the upper side, and two groups of limit rods 22 are fixedly provided on the upper side of the limit plate 5. Both groups of limit rods 22 are movable through the mounting block 4 and extend to the upper side. By rotating the threaded rod 21, the limit plate 5 can be easily driven to move upward or downward, thereby facilitating fine-tuning the use height of the limit plate 5 and the first positioning plate 9, further improving the applicability of the device.

[0033] Working principle: When disassembling the gear, first place the gear shaft on the fixed frame 1 so that the gear shaft passes through the bearing push ring 20 until the bearing fits the bearing push ring 20, and then turn on the first electric push rod 3 through an external power supply. The first electric push rod 3 drives the mounting block 4 and the limit plate 5 to move downward until the limit plate 5 is pressed on the upper side of the gear shaft, and then turn on the second electric push rod 15 to drive the fixing rod 16 to move. When the fixing rod 16 moves, it drives the second positioning plate 17 to move until the second positioning plate 17 fits the outer end of the gear shaft, and finally turn on the hydraulic cylinder 18 to push the support rod 19 and the bearing push ring 20 to move. When the bearing push ring 20 moves, it can apply thrust to the bearing until the bearing is pushed away from the gear shaft. Similarly, when installing the bearing, you only need to put the bearing sleeve on the outside of the gear shaft first, and then push the bearing to the appropriate position on the gear shaft by moving the bearing push ring 20.
