Description

Technical Field

[0001] This utility model relates to the field of bearing fixture technology, specifically a rotor bearing press-fit fixture. Background Technology

[0002] Rotor bearings are widely used in equipment such as motors, turbines, various pumps and turbo compressors. Their main function is to support and stabilize rotating parts, reduce friction, improve operating efficiency, and ensure that mechanical equipment operates in a high-efficiency and stable state by precisely controlling the rotation of the rotor.

[0003] Existing rotor bearing press-fit fixtures, due to their unique structure, struggle to precisely limit the relative positions of the gearbox, female rotor, and male rotor during actual operation. This necessitates manual intervention from installers. Specifically, operators must continuously support the male and female rotors during the press-fit process to ensure proper alignment and positioning with the gearbox. Furthermore, improper force control or operational errors during rotor support can damage the rotor surface, negatively impacting the durability and reliability of the rotor bearing in later production. Therefore, we offer a rotor bearing press-fit fixture. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a rotor bearing press-fit fixture.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotor bearing press-fit fixture, comprising a mounting base, a gearbox movably connected to the outer wall of the top of the mounting base, and a female rotor and a male rotor rotatably connected to both sides of the bottom surface of the gearbox, a set of positioning holes being simultaneously opened on both sides of the top surface of the mounting base, and multiple mounting holes being opened on both sides of the bottom surface of the mounting base, multiple positioning pins penetratingly connected to both sides of the inside of the gearbox, with the bottom of the outer wall of the positioning pin located at the center inside the positioning hole, a movable rotating shaft being fixedly connected to the center inside the female rotor and the male rotor, and a mounting shim being provided on the outer wall of the bottom end of the movable rotating shaft, one side of the top surface of the mounting shim fitting against the outer wall of the bottom end of the movable rotating shaft, and the bottom end of the outer wall of the mounting shim located at the top of the mounting hole, and a set of screws rotatably connected to both sides of the inside of the gearbox, with a mounting knob fixedly connected to the outer wall of the top end of the screw.

[0006] As described above, the bottom outer wall of the positioning pin is connected through to one side of the top surface of the gearbox, and the top of the outer wall of the positioning pin is slidably connected to one side of the inside of the gearbox.

[0007] As described above, the outer wall of the bottom end of the positioning pin is connected through to the top end of the positioning hole, and the bottom of the outer wall of the positioning pin is slidably connected to the center of the positioning hole.

[0008] As described above, the outer walls of the top of the plurality of movable shafts are respectively connected through to the center of the bottom surface of the female rotor and the male rotor, and the outer walls of the plurality of movable shafts are respectively fixedly connected to the center of the inside of the female rotor and the male rotor. One side of the bottom surface of the gearbox is connected through to the top of the inside of the movable shaft, and one side of the bottom surface of the gearbox is rotatably connected to the top of the inner wall of the movable shaft.

[0009] As described above, one side of the top surface of the mounting pad is connected through to the bottom of the inner side of the movable shaft, and the top of one side of the mounting pad is rotatably connected to the bottom of the inner wall of the movable shaft.

[0010] As described above, one side of the bottom surface of the mounting pad is connected through the center of the mounting hole, and the other side of the bottom surface of the mounting pad is slidably connected to the top of the mounting hole.

[0011] As described above, the outer wall of the bottom end of the screw is connected through to one side of the top surface of the gearbox, and the top end of the outer wall of the screw is slidably connected to one side of the inside of the gearbox. The outer wall of the bottom end of the screw is connected through to one side of the top surface of the mounting pad, and the bottom end of the outer wall of the screw is rotatably connected to one side of the inside of the mounting pad through a thread.

[0012] Compared with the prior art, this rotor bearing press-fitting fixture has the following advantages:

[0013] 1. In the press-fitting process of the rotor bearing, the gearbox is placed on the top surface of the mounting base, and the openings on both sides inside the gearbox are aligned with the positioning holes on the top surface of the mounting base. Then, the positioning pins are inserted from the openings on both sides of the top surface of the gearbox into the positioning holes, which can effectively limit the gearbox and restrict it to the center of the top of the mounting base in the horizontal direction, which facilitates the subsequent installation of the female rotor and male rotor at the bottom of the gearbox.

[0014] II. In the press-fitting process of the rotor bearing, the mounting shim is first fixed to the bottom of the mounting base through the mounting hole. Then, the female and male rotors are placed into the mounting base in sequence, ensuring that the top surface of the mounting shim can be inserted into the bottom of the movable shaft. At this time, the mounting shim plays a preliminary limiting role for the female and male rotors. Next, the openings on both sides of the gearbox are aligned with the positioning holes and placed on the top of the mounting base. Then, multiple positioning pins are inserted from one side of the gearbox into the positioning holes, so that the gearbox, mounting shim, female and male rotors form a mutually restrictive relationship. Finally, by inserting multiple screws from one side of the top surface of the gearbox and rotating the mounting knob, the mounting shim is pulled upward by the thread action of the screw outer wall, thus successfully installing the female and male rotors at the bottom of the gearbox. Thus, through the above steps, the mutual interlocking and precise limiting between the mounting shim, gearbox and movable shaft are achieved, and the yield rate of the rotor bearing during the installation process is effectively improved.

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a rotor bearing press-fit fixture, including a mounting base 1, a gearbox 2 movably connected to the outer wall of the top of the mounting base 1, and a female rotor 3 and a male rotor 301 rotatably connected to both sides of the bottom surface of the gearbox 2, respectively. A set of positioning holes 201 are simultaneously opened on both sides of the top surface of the mounting base 1, and multiple mounting holes 302 are opened on both sides of the bottom surface of the mounting base 1. Multiple positioning pins 202 are penetratingly connected to both sides of the inside of the gearbox 2, and the bottom of the outer wall of the positioning pins 202 is positioned... At the center of the positioning hole 201, a movable shaft 303 is fixedly connected to the center of both the female rotor 3 and the male rotor 301. A mounting shim 304 is provided on the outer wall of the bottom end of the movable shaft 303. One side of the top surface of the mounting shim 304 is in contact with the outer wall of the bottom end of the movable shaft 303. The bottom end of the outer wall of the mounting shim 304 is located at the top of the mounting hole 302. A set of screws 305 are rotatably connected to both sides of the inside of the gearbox 2. An installation knob 306 is fixedly connected to the outer wall of the top end of the screws 305.

[0023] During the press-fitting of the rotor bearing, the mounting shim 304 is first fixed to the bottom of the mounting base 1 through the mounting hole 302. Then, the female rotor 3 and the male rotor 301 are placed in sequence, ensuring that the top side of the mounting shim 304 is inserted into the bottom of the movable shaft 303 to initially limit the female rotor 3 and the male rotor 301. Next, the openings on both sides of the gearbox 2 are aligned with the positioning holes 201 and placed on the top of the mounting base 1. Then, multiple positioning pins 202 are inserted into the positioning holes 201 from the inside of the gearbox 2 to restrict the gearbox 2, the mounting shim 304, the female rotor 3 and the male rotor 301. Finally, the screw 305 is inserted from the top side of the gearbox 2, and the mounting knob 306 is rotated to pull the mounting shim 304 upward using the thread action, completing the installation of the female rotor 3 and the male rotor 301 at the bottom of the gearbox 2.

[0024] like Figure 1-4 As shown, the bottom outer wall of the positioning pin 202 is connected through to one side of the top surface of the gearbox 2, and the top of the outer wall of the positioning pin 202 is slidably connected to one side of the inside of the gearbox 2, so that the positioning pin 202 can be smoothly inserted into one side of the inside of the gearbox 2.

[0025] As described above, the bottom outer wall of the positioning pin 202 is connected through to the top of the positioning hole 201, and the bottom of the outer wall of the positioning pin 202 is slidably connected to the center of the positioning hole 201, so that the positioning pin 202 can be inserted into the center of the positioning hole 201 to limit the gearbox 2.

[0026] like Figure 1-4As shown, the outer walls of the top of multiple movable shafts 303 are respectively connected through the center of the bottom surface of the female rotor 3 and the male rotor 301, and the outer walls of multiple movable shafts 303 are respectively fixedly connected to the center of the inside of the female rotor 3 and the male rotor 301. One side of the bottom surface of the gearbox 2 is connected through the top of the inside of the movable shaft 303, and one side of the bottom surface of the gearbox 2 is rotatably connected to the top of the inner wall of the movable shaft 303. By passing through the top of the inside of the movable shaft 303 from one side of the bottom surface of the gearbox 2, the female rotor 3 and the male rotor 301 can be initially limited.

[0027] The top surface of the mounting shim 304 is connected through to the bottom of the inner side of the movable shaft 303, and the top of one side of the mounting shim 304 is rotatably connected to the bottom of the inner wall of the movable shaft 303, so that the mounting shim 304 can further limit the female rotor 3 and the male rotor 301 through the movable shaft 303.

[0028] The bottom side of the mounting pad 304 is connected through the center of the mounting hole 302, and the bottom side of the mounting pad 304 is slidably connected to the top of the mounting hole 302, allowing the mounting pad 304 to be placed at the bottom of the mounting base 1 through the mounting hole 302.

[0029] The outer wall of the bottom end of the screw 305 is connected through to one side of the top surface of the gearbox 2, and the top of the outer wall of the screw 305 is slidably connected to one side of the inside of the gearbox 2. The outer wall of the bottom end of the screw 305 is connected through to one side of the top surface of the mounting pad 304, and the bottom end of the outer wall of the screw 305 is rotatably connected to one side of the inside of the mounting pad 304 by a thread. By rotating the screw 305, the mounting pad 304 is driven to abut against the movable rotating shaft 303, thereby fixing the female rotor 3 and the male rotor 301 to the bottom of the gearbox 2.

[0030] Working principle: The positioning pin 202 can be smoothly inserted into one side of the gearbox 2, and the positioning pin 202 can be inserted into the center of the positioning hole 201 to limit the gearbox 2. The bottom side of the gearbox 2 passes through the top of the movable shaft 303, which can initially limit the female rotor 3 and the male rotor 301. The mounting shim 304 can further limit the female rotor 3 and the male rotor 301 through the movable shaft 303. The mounting shim 304 can be placed at the bottom of the mounting base 1 through the mounting hole 302. By rotating the screw 305, the mounting shim 304 is driven to abut against the movable shaft 303, thus fixing the female rotor 3 and the male rotor 301 to the bottom of the gearbox 2.
