Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and testing technology, specifically to a main bearing gear ring testing device. Background Technology

[0002] The main bearing gear ring is typically made of steel, and its basic structure consists of an inner ring, a gear ring, and an outer ring. The gear ring connects the inner and outer rings, and is fixed by the meshing of its teeth with the grooves of the inner and outer rings. The main bearing is a triaxial bearing with an internal gear ring for transmitting the torque of the cutterhead. It is designed based on maximum propulsion load, especially to anticipate strong overturning forces generated in curved sections or along the course of the curve, and in unstable surrounding rock.

[0003] The manufacturing precision, installation quality, and maintenance of the main bearing gear ring have a significant impact on the bearing's stability, accuracy, and lifespan. Poor manufacturing precision, severe wear, or improper installation of the gear ring can lead to unstable bearing operation, noise, or even failure, severely impacting machine production and operation. Therefore, strict quality control of the main bearing gear ring is essential during the manufacturing, installation, and maintenance of bearings to ensure it meets usage requirements and extends bearing life. Furthermore, regular inspection and maintenance of the main bearing gear ring are necessary during use to promptly identify and address potential problems, ensuring normal machine operation and production efficiency.

[0004] However, in practical applications, the flatness of the main bearing gear ring is one of the important indicators for measuring its manufacturing quality, directly affecting the operational stability and service life of mechanical equipment. Traditional testing methods mostly rely on manual measurement using tools such as dial indicators and gauge blocks, resulting in low measurement efficiency and accuracy that is greatly affected by human factors. Utility Model Content

[0005] The purpose of this invention is to provide a main bearing gear ring inspection device to address the issue mentioned in the background art, where the flatness of the main bearing gear ring is a crucial indicator of its manufacturing quality, directly impacting the operational stability and service life of mechanical equipment. Traditional inspection methods often rely on manual measurement using tools such as dial indicators and gauge blocks, resulting in low measurement efficiency and accuracy significantly affected by human factors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a testing platform, with a first drive motor fixedly mounted at its top. A first pulley is fixedly mounted on the upper drive shaft of the first drive motor. A second pulley is connected to the outer end of the first pulley via a belt drive. A rotating shaft is fixedly mounted in the middle of the second pulley. A horizontal rotating platform for driving the main bearing gear ring to rotate horizontally is fixedly mounted on the top of the rotating shaft. A second drive motor is fixedly mounted on the rear side of the upper end of the testing platform. A transmission screw is fixedly mounted on the front drive shaft of the second drive motor. The transmission screw has an outer curved screw in the middle. A movable platform is connected to the upper part of the movable platform. First limiting slide rods are movably connected to both sides of the lower end of the movable platform. An electric telescopic rod is fixedly installed through the middle of the front end of the movable platform. A lifting plate is fixedly installed on the lower telescopic part of the electric telescopic rod. Second limiting slide rods are fixedly installed on both sides of the upper end of the lifting plate. A detection rod is movably connected through the front end of the lifting plate. A distance measuring disk is fixedly installed at the top of the detection rod. A detection ball wheel is rotatably connected to the bottom of the detection rod. A support spring is fixedly installed on the outer curved surface of the lower end of the detection rod. A U-shaped frame is fixedly installed on the front side of the upper end of the lifting plate. A distance measuring sensor is fixedly installed through the upper end of the U-shaped frame.

[0007] Preferably, a control power cabinet is fixedly installed at the bottom of the testing platform, and a testing display is fixedly installed at the top side of the testing platform.

[0008] Preferably, the rotating shaft is rotatably connected to the front side of the upper end of the testing platform via a rotating shaft.

[0009] Preferably, there are two first limiting slide bars, which are symmetrically distributed on both sides of the lower end of the moving platform.

[0010] Preferably, there are two second limiting slide rods, which are symmetrically distributed on both sides of the upper end of the lifting plate, and the upper end of the second limiting slide rod is connected to both sides of the front end of the moving platform through and fitting together.

[0011] Preferably, the upper end of the support spring is fixed to the lower end face of the lifting plate.

[0012] Preferably, the ranging sensor and the ranging disk are on the same vertical line.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the bottom of the detection ball wheel remains in contact with the outer surface of the main bearing gear ring, the first drive motor is activated. When the first drive motor is activated, it sequentially drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the horizontal rotating table to rotate horizontally. When the horizontal rotating table rotates horizontally, it drives the main bearing gear ring to rotate horizontally. When the main bearing gear ring rotates horizontally, the detection ball wheel rolls on the outer surface of the main bearing gear ring. When the outer surface of the main bearing gear ring is uneven, the detection ball wheel will follow the up-and-down movement of the outer surface of the main bearing gear ring. When the detection ball wheel moves up and down, it drives the measuring disk to move up and down linearly through the detection rod. When the measuring disk moves up and down linearly, the distance of the measuring disk is detected by the measuring sensor, which makes it easy to detect the flatness of the outer surface of the main bearing gear ring.

[0015] This invention also features a second drive motor that, when activated, drives the transmission screw to rotate. When the transmission screw rotates, the force generated by the threaded connection causes the moving table to move linearly back and forth along the outer curved surface of the first limit slide bar. As the moving table moves linearly back and forth, it simultaneously drives the detection ball wheel to move linearly back and forth to adjust the detection position. This allows for the detection of the flatness of the outer surface of the main bearing gear ring while facilitating linear adjustment of the detection position. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a main bearing gear ring testing device: it includes a testing platform 1, and a control power cabinet is fixedly installed at the bottom of the testing platform 1, and a testing display is fixedly installed at the top side of the testing platform 1.

[0023] A first drive motor 2 is fixedly installed at the top of the inner support of the testing table 1. A first pulley 3 is fixedly installed on the upper drive shaft of the first drive motor 2. A second pulley 4 is connected to the outer end of the first pulley 3 via a belt drive. A rotating shaft column 5 is fixedly installed in the middle of the second pulley 4, and the rotating shaft column 5 is rotatably connected to the front side of the upper end of the testing table 1 through a rotating shaft. A horizontal rotating table 6 for driving the main bearing gear ring to rotate horizontally is fixedly installed at the top of the rotating shaft column 5. A second drive motor 7 is fixedly installed on the rear side of the upper end of the testing table 1. A transmission screw 8 is fixedly installed on the front drive shaft of the second drive motor 7. A movable table 9 is connected to the outer curved thread of the transmission screw 8. Two first limiting slide rods 10 are movably connected through and fitted on both sides of the lower end of the movable table 9, and the first limiting slide rods 10 are symmetrically distributed on both sides of the lower end of the movable table 9. An electric telescopic rod 11 is fixedly installed through the middle of the front end of the movable table 9. The lower telescopic part of the electric telescopic rod 11 is telescopically connected. A lifting plate 12 is fixedly installed. Two second limiting slide rods 19 are fixedly installed on both sides of the upper end of the lifting plate 12, and are symmetrically distributed on both sides of the upper end of the lifting plate 12. The upper ends of the second limiting slide rods 19 are connected to the front ends of the moving platform 9 through and fit together, so that the moving platform 9 can be linearly limited by the second limiting slide rods 19. A detection rod 13 is connected to the front end of the lifting plate 12 through and fit together. A distance measuring disk 14 is fixedly installed on the top of the detection rod 13. A detection ball wheel 15 is rotatably connected to the bottom of the detection rod 13. A support spring 16 is fixedly installed on the outer curved surface of the lower end of the detection rod 13, and the upper end of the support spring 16 is fixed to the lower end face of the lifting plate 12, so that the detection rod 13 is elastically supported by the support spring 16. A U-shaped frame 17 is fixedly installed on the front side of the upper end of the lifting plate 12. A distance measuring sensor 18 is fixedly installed through the upper end of the U-shaped frame 17, and the distance measuring sensor 18 and the distance measuring disk 14 are on the same vertical line.

[0024] Working principle: In use, this utility model fixes the main bearing gear ring to be tested to the upper end of the horizontal rotating table 6. When the main bearing gear ring is fixedly connected to the upper end of the horizontal rotating table 6, the electric telescopic rod 11 is extended downward by control. When the electric telescopic rod 11 extends downward, it will drive the lifting plate 12 to move downward in a straight line. When the lifting plate 12 moves downward in a straight line, it will simultaneously drive the detection rod 13 to move downward in a straight line. When the detection rod 13 moves downward in a straight line, it will drive the detection ball wheel 15 to move downward in a straight line and fit against the outer surface of the main bearing gear ring. When the detection ball wheel 15 fits against the outer surface of the main bearing gear ring, the elastic support of the detection rod 13 by the support spring 16 will keep the bottom of the detection ball wheel 15 always in contact with the outer surface of the main bearing gear ring.

[0025] When the bottom of the detection ball wheel 15 remains in contact with the outer surface of the main bearing gear ring, the first drive motor 2 is activated by control. When the first drive motor 2 is activated, it drives the first pulley 3 to rotate. When the first pulley 3 rotates, it drives the second pulley 4 to rotate via belt drive. When the second pulley 4 rotates, it drives the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, it drives the horizontal rotating table 6 to rotate horizontally. When the horizontal rotating table 6 rotates horizontally, it drives the main bearing gear ring to rotate horizontally. When the main bearing gear ring rotates horizontally, the detection ball wheel 15 rolls on the outer surface of the main bearing gear ring. When the outer surface of the main bearing gear ring is uneven, the detection ball wheel 15 will follow the up and down movement of the outer surface of the main bearing gear ring. When the detection ball wheel 15 moves up and down, it drives the measuring disk 14 to move up and down linearly via the detection rod 13. When the measuring disk 14 moves up and down linearly, the distance of the measuring disk 14 is detected by the measuring sensor 18, which makes it easy to detect the flatness of the outer surface of the main bearing gear ring.

[0026] Simultaneously, by controlling the activation of the second drive motor 7, when the second drive motor 7 is activated, it will drive the transmission screw 8 to rotate. When the transmission screw 8 rotates, the force generated by the threaded connection will drive the moving table 9 to move linearly back and forth along the outer curved surface of the first limit slide bar 10. When the moving table 9 moves linearly back and forth, it will synchronously drive the detection ball wheel 15 to move linearly back and forth to adjust the detection position. This allows for the detection of the flatness of the outer surface of the main bearing gear ring while facilitating the adjustment of the detection position by linear movement back and forth.
