The drive bearing connects the traction gear to the hollow axle sleeve of the wheelset drive unit, transmitting the torque of the traction motor and enabling locomotive operation. Two sets of drive bearings of different specifications are installed inside the traction gear. According to traditional methods, the installation steps for the drive bearings on the traction gear are as follows: First, the first type of matching drive bearing is placed into the mounting hole of the traction gear; multiple people need to stand around the traction gear and use a copper rod to evenly tap it in.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figure 1-3 As shown, a press-fitting device for a fully suspended locomotive drive bearing includes a processing table 1, with support legs 2 on both sides of the bottom wall of the processing table 1, a base 3 on the front side of the top wall of the processing table 1, cylinders 4 on both sides of the top wall of the base 3, and a clamping seat 5 on the inner drive end of the cylinder 4.

[0026] A bearing limiting mechanism is provided on the left side of the top wall of the processing table 1.

[0027] Furthermore, the bearing limiting mechanism includes a lifting mechanism and a telescopic mechanism. The lifting mechanism includes a cylinder 9, with multiple grooves on the inner wall of the cylinder 9. A motor 10 is installed on the inner bottom wall of the cylinder 9. The output end of the motor 10 is locked with a lead screw 11 via a coupling. A circular block 12 is threaded onto the outer wall of the lead screw 11. Multiple sliders 13 are installed on the outer wall of the circular block 12 and are slidably connected in the grooves. A circular rod 14 is installed on the top wall of the circular block 12. A top seat 15 is installed on the top wall of the circular rod 14. A telescopic mechanism is installed on the outer wall of the top seat 15. The motor 10 causes the lead screw 11 to rotate, and the lead screw 11 causes the circular block 12 to drive the sliders 13, the circular rod 14, the top seat 15, the connecting cylinder 16, the sliding rod 19, and the limiting seat 20 to move downward.

[0028] Furthermore, the round rod 14 has a hollow structure, and the outer wall of the lead screw 11 extends into the round rod 14. By tucking the outer wall of the lead screw 11 into the round rod 14, the overall height of the lifting mechanism can be reduced.

[0029] Furthermore, the telescopic mechanism includes a connecting cylinder 16, with a hydraulic telescopic rod 17 on the inner wall of the connecting cylinder 16. A connecting block 18 is provided at the driving right end of the hydraulic telescopic rod 17, and a sliding rod 19 is provided on the right end wall of the connecting block 18. The right end wall of the sliding rod 19 extends out of the connecting cylinder 16 and is provided with a limiting seat 20. Through holes are provided on both the left and right sides of the outer wall of the limiting seat 20. The connecting block 18 is driven by the hydraulic telescopic rod 17 to move the sliding rod 19 and the limiting seat 20 to the left, so that another through hole on the limiting seat 20 is aligned with the mounting hole of the traction gear bearing.

[0030] Furthermore, the limiting seat 20 is located between the pressure block 8 and the base 3. The pressure block 8 is driven to move downward by the hydraulic cylinder 7, and the bearing is easily pressed into the traction gear through the pressure block 8.

[0031] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art.

The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0032] One specific application of this embodiment is:

[0033] When in use, place the traction gear on the top of the base 3, and drive the clamp 5 to move inward through the cylinders 4 on both sides, and clamp and fix the traction gear through the clamp 5.

[0034] The motor 10 causes the lead screw 11 to rotate, which in turn causes the round block 12 to move the slider 13, round rod 14, top seat 15, connecting cylinder 16, slide rod 19 and limit seat 20 downward, so that a through hole on the limit seat 20 is aligned with the bearing mounting position of the traction gear. The bearing is then placed into the through hole, and the hydraulic cylinder 7 drives the pressure block 8 to move downward, pressing the bearing into the traction gear, thus completing the pressing of one bearing.

[0035] By reversing the start motor 10, the limit seat 20 is moved upward. The hydraulic telescopic rod 17 drives the connecting block 18 to move the slide rod 19 and the limit seat 20 to the left, aligning another through hole on the limit seat 20 with the traction gear bearing mounting hole. The motor 10 drives the limit seat 20 downward, placing the bearing into the through hole. The hydraulic cylinder 7 drives the pressure block 8 downward to perform the pressing operation on the bearing, thus completing the pressing operation on the traction gear bearing.
