Description

Technical Field

[0001] This invention relates to the field of large bearing repair technology, specifically a bearing grinding kit or a bearing grinding process. Background Technology

[0002] Large bearings such as tunnel boring machine main drive bearings, ship hoisting slewing bearings, and wind turbine bearings are all precision components, especially bearing raceways with very high precision. However, these bearings operate in harsh environments and often suffer damage such as rust, dents, and peeling on the raceway surface. These damages need to be repaired in time, otherwise the bearing's load-bearing capacity will decrease and the bearing will fail prematurely, which may cause significant economic losses or accidents in severe cases.

[0003] Currently, the repair of damaged raceways in large bearings typically involves transporting them back to the bearing factory for precision grinding. For example, Chinese patent CN101797710A, published on August 11, 2010, entitled "Repair Grinding Machine Tool for Large Rolling Bearing Raceways," can be used for repair. Large bearings range in diameter from several meters to over ten meters, making transportation difficult, expensive, and time-consuming, thus delaying project schedules. Summary of the Invention

[0060] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] A bearing grinding kit, comprising:

[0062] The grinding assembly includes a grinding wheel 15, a grinding wheel drive unit 13, a grinding feed assembly 14 and a grinding support frame 16 connected in sequence. The grinding wheel 15 is capable of grinding the surface of the bearing to be processed.

[0063] The drive assembly is capable of driving the moving ring 1 of the bearing to rotate.

[0064] The bearing grinding kit is mainly used for on-site grinding and repair of bearings, specifically large bearings such as slewing bearings. A detailed description is given below using a slewing bearing as an example. The bearing includes a moving ring 1, a first fixed ring 2, a second fixed ring 12, an auxiliary thrust roller 3, radial rollers 8, and a main thrust roller 10. The first fixed ring 2 and the second fixed ring 12 are connected vertically by bolts. Figure 1 and Figure 2 As shown. The moving ring 1 can be fitted inside the first fixed ring 2 and the second fixed ring 12, or it can be fitted outside the first fixed ring 2 and the second fixed ring 12. When the moving ring 1 is fitted inside the first fixed ring 2 and the second fixed ring 12, the inner circumferential surface of the moving ring 1 is provided with internal teeth 101. When the moving ring 1 is fitted outside the first fixed ring 2 and the second fixed ring 12, the outer circumferential surface of the moving ring 1 is provided with external teeth.

[0065] The moving ring (moving ring 1) of the bearing is driven by a drive assembly, and the raceway of the bearing ring to be processed can rotate with the moving ring. The grinding assembly is fixed on the fixed ring (first fixed ring 2 or second fixed ring 12) of the bearing, and the grinding assembly is used to grind the bearing ring to be processed. During the rotation, the axial grinding accuracy of the bearing ring is guaranteed by the rotational accuracy of the bearing itself, thereby achieving high-precision grinding and repair of the raceway of the bearing ring to be processed.

[0066] In this embodiment, the grinding support frame 16 is used differently depending on the raceway being ground. The grinding support frame 16 includes a moving ring auxiliary push raceway grinding frame 1601, a first fixed ring auxiliary push raceway grinding frame 1602, a first fixed ring lower stop grinding frame 1603, a moving ring main push raceway grinding frame 1604, a moving ring radial raceway grinding frame 1605, a second fixed ring main push raceway grinding frame 1606, a second fixed ring upper stop grinding frame 1607, and a second fixed ring radial raceway grinding frame 1608. When processing different raceways, the corresponding grinding support frame 16 is selected.

[0067] There are eight types of grinding support frames 16, but these eight types also share common features. Specifically, each type of grinding support frame 16 includes a lower horizontal plate 1611, a middle horizontal plate 1612, and an upper horizontal plate 1613 arranged sequentially from bottom to top. The lower horizontal plate 1611, the middle horizontal plate 1612, and the upper horizontal plate 1613 are connected and fixed by the grinding frame column 1614. Figure 3 As shown.

[0068] In use, the lower horizontal plate 1611 and the middle horizontal plate 1612 of the grinding head can clamp and fix the first fixed ring 2 or the second fixed ring 12 of the bearing. When the moving ring 1 is fitted inside the first fixed ring 2 and the second fixed ring 12, the grinding head column 1614 is located outside the first fixed ring 2 or the second fixed ring 12 along the diameter direction of the bearing. When the moving ring 1 is fitted outside the first fixed ring 2 and the second fixed ring 12, the grinding head column 1614 is located inside the first fixed ring 2 or the second fixed ring 12 along the diameter direction of the bearing. The grinding wheel drive unit 13 is connected to the upper horizontal plate 1613 of the grinding head through the grinding feed assembly 14, which enables the grinding wheel drive unit 13 and the grinding wheel 15 to move radially and axially along the bearing.

[0069] The grinding feed assembly 14 can employ existing technology; any mechanism that allows an object to move along the X and Y axes can be used. For example, the grinding feed assembly 14 includes a radial movement assembly and an axial movement assembly connected in sequence. The radial movement assembly enables the axial movement assembly and the grinding wheel drive unit 13 to move radially along the bearing. The radial movement assembly includes a radial movement seat, a radial lead screw, and a radial slider connected in sequence, while the axial movement assembly includes an axial movement seat, an axial lead screw, and an axial slider connected in sequence. The axial movement assembly is fixedly connected to the radial slider, and the grinding wheel drive unit 13 is fixedly connected to the axial slider.

[0070] In this embodiment, the grinding wheel drive unit 13 is a grinding motor. The output shaft of the grinding motor is coaxially connected and fixed to the grinding wheel 15. The axis of the output shaft of the grinding motor coincides with the axis of the grinding wheel 15. The grinding motor can drive the grinding wheel 15 to rotate. In use, the grinding support frame 16 is connected and fixed to the first fixed ring 2 or the second fixed ring 12 of the bearing. The output shaft of the grinding motor can be parallel to the axis of the bearing, and the grinding wheel 15 can contact the raceway of the bearing to be processed. Figure 3 As shown.

[0071] In this embodiment, the bearing grinding kit further includes a drive support frame 19. The drive support frame 19 varies depending on the raceway being ground. It includes a moving ring auxiliary push raceway grinding support frame, a first fixed ring auxiliary push raceway grinding support frame, a first fixed ring lower stop grinding support frame, a moving ring main push raceway grinding support frame, a moving ring radial raceway grinding support frame, a second fixed ring main push raceway grinding support frame, a second fixed ring upper stop grinding support frame, and a second fixed ring radial raceway grinding support frame. When processing different raceways, the appropriate drive support frame 19 is selected.

[0072] In this embodiment, the drive assembly includes a drive motor 17, a reducer 18, and a gear 21 connected sequentially from top to bottom. The drive motor 17 can drive the gear 21 to rotate, and the gear 21 can mesh with the internal or external teeth of the moving ring 1 of the bearing. The drive assembly can be connected to the first fixed ring 2 or the second fixed ring 12 of the bearing via a drive support frame 19. Alternatively, the drive assembly can rotate at the center of the bearing and connect to the internal gear ring via a rod to achieve the drive function. Alternative solutions offer better versatility, but require a reducer or a speed-regulating motor, such as... Figure 4 As shown.

[0073] There are eight types of drive support frames 19, but they also share common features. Specifically, each drive support frame 19 includes a lower drive frame horizontal plate 1911, a middle drive frame horizontal plate 1912, and an upper drive frame horizontal plate 1913, arranged sequentially from bottom to top. These three horizontal plates are connected and fixed via drive frame columns 1914. The drive motor 17 is connected and fixed to the upper drive frame horizontal plate 1913. The reducer 18 is located between the middle and upper drive frame horizontal plates 1912 and 1913, and the gear 21 is located between the lower and middle drive frame horizontal plates 1911 and 1912. In use, the lower drive frame horizontal plate 1911 can be connected and fixed to the first retaining ring 2 or the second retaining ring 12 of the bearing. When the moving ring 1 is fitted inside the first fixed ring 2 and the second fixed ring 12, the drive frame column 1914 is located inside the first fixed ring 2 or the second fixed ring 12 along the diameter direction of the bearing. When the moving ring 1 is fitted outside the first fixed ring 2 and the second fixed ring 12, the drive frame column 1914 is located outside the first fixed ring 2 or the second fixed ring 12 along the diameter direction of the bearing.

[0074] Preferably, the drive support frame 19 further includes a drive frame connecting rod 1921, which comprises an upper horizontal section 1922, a vertical section 1923, and a lower horizontal section 1924 connected sequentially from top to bottom. In use, one end of the upper horizontal section 1922 is fixedly connected to the upper cross plate 1913 of the drive frame, and the other end of the upper horizontal section 1922 is fixedly connected to the upper end of the vertical section 1923. One end of the lower horizontal section 1924 can be fixedly connected to the first fixed ring 2 or the second fixed ring 12 of the bearing, and the other end of the lower horizontal section 1924 is fixedly connected to the lower end of the vertical section 1923. When the moving ring 1 is fitted inside the first fixed ring 2 and the second fixed ring 12, the vertical section 1923 is located outside the first fixed ring 2 or the second fixed ring 12 along the diameter direction of the bearing. When the moving ring 1 is fitted outside the first fixed ring 2 and the second fixed ring 12, the upright section 1923 is located inside the first fixed ring 2 or the second fixed ring 12 along the diameter direction of the bearing. The function of the drive frame connecting rod 1921 is to make the drive assembly connection more stable, such as... Figure 4 As shown.

[0075] As needed, the bearing grinding kit may further include a first fixed ring support fixture 20. After the first fixed ring 2 rotates 180° around its diameter, the first fixed ring 2 can be coaxially connected and fixed to the moving ring 1 via the first fixed ring support fixture 20. The first fixed ring support fixture 20 can be a metal strip or a metal ring, preferably a metal strip, and the number of first fixed ring support fixtures 20 is at least three. In use, at least three first fixed ring support fixtures 20 are evenly spaced along the circumference of the bearing, and the first fixed ring support fixtures 20 extend along the diameter direction of the bearing. The two ends of the first fixed ring support fixtures 20 are detachably connected (e.g., bolted) to the first fixed ring 2 and the moving ring 1, respectively. Figures 4 to 6 As shown.

[0076] As needed, the bearing grinding kit may further include multiple radial concentric adjustment components, each containing a guide wheel 22 and a support arm 24. The support arm 24 extends horizontally, with the guide wheel 22 located at one end. In use, at least three radial concentric adjustment components are evenly spaced along the circumference of the bearing. The axis of the guide wheel 22 is parallel to the axis of the bearing. After the first fixed ring 2 rotates 180° around its diameter, the support arm 24 is vertically and vertically fixed to the first fixed ring 2 via a clamping screw 23. The clamping screw 23 passes through the lower stop 201 of the first fixed ring 2, allowing the outer circumferential surface of the guide wheel 22 to contact the outer circumferential surface of the moving ring 1. The distance from the guide wheel 22 to the axis of the bearing is adjustable. By adjusting the distance from the guide wheel 22 to the axis of the bearing, the position of the axis of the first fixed ring 2 can be adjusted, thereby aligning the axis of the first fixed ring 2 with the axis of the moving ring 1. Figure 7 As shown.

[0077] In use, the grinding assembly and drive assembly are arranged at uniform intervals along the circumference of the bearing, as are multiple first fixed-ring support fixtures 20 and multiple radial concentric adjustment assemblies. The grinding assembly, drive assembly, first fixed-ring support fixtures 20, and radial concentric adjustment assemblies are all arranged at uniform intervals along the circumference of the bearing. All components are detachably connected to the bearing. During the grinding process, axial accuracy is ensured by the rotation of the bearing auxiliary thrust roller raceway, while radial accuracy is ensured by the guidance of the radial concentric adjustment assemblies.

[0078] In addition to the components mentioned above, a grinding fluid supply system can be added to provide cooling for the grinding process, depending on the grinding requirements. To improve grinding accuracy, a post-grinding inspection system can also be added. This system promptly feeds back the inspection data to the grinding system, allowing the grinding feed mechanism to adjust the grinding depth in a timely manner, providing accuracy compensation for the grinding process. The grinding machine and principles of this invention can also be used to perform grinding processes when there are multiple bearing rings.

[0079] The following describes a bearing grinding method. The bearing grinding method uses the aforementioned bearing grinding kit and includes one or more of the following steps: moving ring auxiliary push raceway grinding, first fixed ring auxiliary push raceway grinding, first fixed ring lower stop grinding, moving ring main push raceway grinding, moving ring radial raceway grinding, second fixed ring main push raceway grinding, second fixed ring upper stop grinding, and second fixed ring radial raceway grinding.

The drive assembly is connected to the second fixed ring 12 via the drive support frame 19 (specifically, the moving ring auxiliary push raceway grinding support frame). The drive assembly drives the moving ring 1 to rotate, and the lower end face of the grinding wheel 15 grinds the moving ring auxiliary push raceway 5. The specific dimensions and shapes of the moving ring auxiliary push raceway grinding support frame 1601 and the moving ring auxiliary push raceway grinding support frame should ensure the smooth progress of the moving ring auxiliary push raceway grinding process.

The first fixed ring 2 is then coaxially connected and fixed to the moving ring 1 via the first fixed ring support fixture 20. The grinding support frame 16 (specifically, the first fixed ring auxiliary push raceway grinding frame 1602) is connected to the second fixed ring 12. The drive assembly is connected to the second fixed ring 12 via the drive support frame 19 (specifically, the first fixed ring auxiliary push raceway grinding support frame). The drive assembly drives the moving ring 1 and the first fixed ring 2 to rotate, and the lower end face of the grinding wheel 15 grinds the first fixed ring auxiliary push raceway 4. The specific dimensions and shape of the first fixed ring auxiliary push raceway grinding frame 1602 and the first fixed ring auxiliary push raceway grinding support frame should ensure the smooth progress of the moving ring auxiliary push raceway grinding step. Figure 4 and Figure 5 As shown.

[0084] The grinding process for the first fixing ring's lower stop includes:

[0085] After removing the first fixed ring 2 and the auxiliary push roller 3, the first fixed ring 2 rotates 180° around its diameter.

The grinding support frame 16 (specifically, the first fixed ring lower stop grinding support frame 1603) is connected to the second fixed ring 12. The drive assembly is connected to the second fixed ring 12 via the drive support frame 19 (specifically, the first fixed ring lower stop grinding support frame). The drive assembly drives the moving ring 1 and the first fixed ring 2 to rotate, and the lower end face of the grinding wheel 15 grinds the lower stop 201 of the first fixed ring 2. The specific dimensions and shape of the first fixed ring lower stop grinding support frame 1603 and the first fixed ring lower stop grinding support frame should ensure the smooth progress of the moving ring auxiliary push raceway grinding step.

By adjusting the distance from the guide wheel 22 to the axis of the bearing, the position of the axis of the first fixed ring 2 can be adjusted so that the axis of the first fixed ring 2 coincides with the axis of the moving ring 1.
