However, when measuring large and heavy gears with an outer diameter greater than 800mm, it is difficult to move the product to be tested, resulting in inconvenience in measurement.

The mounting body is moved to make the standard gear mesh with the slewing ring gear product to be measured, and then the mounting body is fixed on the assembly workbench, and the standard gear is driven by the elastic member to always have a tendency to move toward the direction of the slewing ring gear product to be measured. Then, the driving motor on the assembly workbench drives the power arm to rotate the slewing ring gear. Due to the coupling effect of the slewing ring gear product to be measured and the standard gear, the slewing ring gear product rotates during the rotation process. There will be radial runout, and the gear ring product transfers the movement to the standard gear, so that the standard gear drives the sliding body to move back and forth in the radial direction of the slewing bearing.

[0022] The following combination Figure 1-Figure 5 This application is described in further detail.

[0023] At present, large and heavy gear ring slewing bearing products usually need to be placed on the assembly workbench for assembly. Figure 1 The assembly workbench mainly includes a base 14 and a support seat 15. The cross section of the base 14 is circular. There are multiple support seats 15 fixed at intervals along the circumference of the base 14. The length direction of the support seat 15 is arranged along the radial direction of the base 14. In order to facilitate the installation and fixation of the slewing bearing gear ring product, a strip hole and a mounting hole are opened on the support seat 15. The length direction of the strip hole is parallel to the length direction of the corresponding support seat 15. When assembling the slewing bearing gear ring product, it is placed on multiple support seats 15. In order to facilitate the rotation of the inner ring or outer ring of the slewing bearing, a drive motor 16 is usually provided at the center of the base 14. A force arm 17 is installed on the output shaft of the drive motor 16. The force arm 17 is slidably provided with an insertion rod. By extending the insertion rod on the force arm 17 into the mounting hole on the inner ring or outer ring of the slewing bearing gear ring product, the drive motor 16 can drive the inner ring or outer ring of the slewing bearing to rotate through the force arm 17.

[0024] Example 1: The present application discloses a slewing gear radial comprehensive total deviation measuring instrument applicable to large and heavy slewing gear ring products with a diameter greater than 800 mm. Figure 2 and Figure 3 The slewing bearing gear radial comprehensive total deviation measuring instrument includes a mounting body 1, a sliding body 2, a standard gear 3, an elastic part and a measuring part; wherein, the mounting body 1 is a rectangular plate, and the mounting body 1 is used to be mounted on the assembly workbench of the slewing bearing gear ring product to be measured; the upper surface of the mounting body 1 is fixed with a guide rail 9, and the guide rail 9 adopts a linear guide rail 9, and the length direction of the guide rail 9 is parallel to the length direction of the mounting body 1, and the sliding body 2 is slidably set on the guide rail 9 along the length direction of the guide rail 9, and the sliding body 2 is a rectangular plate, and the length direction of the sliding body 2 is parallel to the length direction of the mounting body 1.

[0025] Reference Figure 2 and Figure 3 The standard gear 3 is rotatably mounted on the sliding body 2 via a bearing seat 21, with its axis of rotation arranged vertically. The standard gear 3 is located at the end of the sliding body 2 away from the mounting body 1 and is used to couple with the slewing ring gear being tested. Specifically, the standard gear 3 features a high-precision tooth profile and pitch, with all parameters consistent with the theoretical design values ​​of the ring gear being tested, and minimal machining errors.

[0026] Reference Figure 2 and Figure 3 The elastic member is provided on the mounting body 1 and is used to drive the standard gear 3 to always have a tendency to move toward the direction close to the slewing bearing gear ring product to be measured; the measuring member is provided on the mounting body 1 and is used to measure the displacement change of the sliding body 2.

[0027] After the slewing ring gear product is assembled, for example, after the internal gear slewing ring gear product is installed on the assembly workbench, the mounting body 1 of the measuring instrument is passed from the inner side of the slewing ring gear product under the gear ring product to be measured and extended outward, and the standard gear 3 is located on the inner side of the gear ring product to be measured, so that the length direction of the mounting body 1 and the sliding direction of the sliding body 2 are both arranged along the radial direction of the slewing ring gear product, and then the standard gear 3 is meshed with the gear ring product to be measured, and the elastic member drives the standard gear 3 to always have a tendency to move toward the direction close to the slewing ring gear product to be measured, and then the mounting body 1 is fixed on the base 14 of the assembly workbench, and then the driving motor 16 on the assembly workbench drives the power arm 17 to rotate the inner ring and gear ring of the slewing bearing, and the gear ring product to be measured The standard gear 3 is driven to rotate. Due to the coupling effect between the ring gear product under test and the standard gear 3, the ring gear product will experience radial runout during the rotation process. The ring gear product transfers the movement amount to the standard gear 3, thereby causing the standard gear 3 and the sliding body 2 to reciprocate in the radial direction of the slewing bearing. The displacement change of the sliding body 2 is measured by the measuring piece, and the movement change of the center of the standard gear 3 is obtained, and then the change of the double meshing center distance is obtained. In this application, there is no need to move the assembled slewing bearing ring gear product under test during measurement. Instead, the measuring instrument only needs to be installed on the assembly workbench of the slewing bearing ring gear product under test to complete the measurement operation, thereby facilitating the measurement of large and heavy slewing bearing ring gear products with an outer diameter greater than 800 mm. It is convenient, practical, and has a wide range of applications.

[0028] Reference Figure 2 and Figure 3 In order to facilitate the installation and fixation of the installation body 1, installation and fixing holes 18 are opened at both ends of the installation body 1. The installation body 1 can be fixed to the required position of the assembly workbench through the installation and fixing holes 18 by bolts or by the cooperation of screws and nuts.

[0029] Reference Figure 2 and Figure 3 The end of the sliding body 2 away from the standard gear 3 is connected to the connecting seat 19 by a bolt, and a sliding rod 6 is fixed to the side of the connecting seat 19 away from the sliding body 2. The length direction of the sliding rod 6 is parallel to the sliding direction of the sliding body 2. A vertical plate 20 is fixed to the mounting body 1 by bolts, and the sliding rod 6 is slidably penetrated on the vertical plate 20; in order to facilitate the standard gear 3 to always have a tendency to move toward the direction close to the slewing bearing gear ring product to be measured during measurement, the elastic member includes a spring 5, the spring 5 is movably mounted on the sliding rod 6, and the spring 5 is located on the side of the vertical plate 20 away from the sliding body 2, one end of the spring 5 is fixed on the vertical plate 20 of the mounting body 1, and the other end is arranged on the side of the sliding rod 6 away from the sliding body 2.

[0030] The elastic force of the spring 5 makes the standard gear 3 on the sliding body 2 always tend to move toward the product direction of the slewing support ring gear, ensuring that the standard gear 3 always remains in meshing with the ring gear when the slewing support ring gear rotates, and can move back and forth in the radial direction with the radial runout of the ring gear. The setting of the slide rod 6 facilitates the installation of the spring 5.

[0031] Reference Figure 2 and Figure 3 In order to facilitate the adjustment of the compression or extension of the spring 5 as needed, an adjusting member for adjusting the compression or extension of the spring 5 is provided on the slide rod 6. Specifically, the adjusting member includes an adjusting nut 7, which is threadedly sleeved on the end of the slide rod 6 away from the sliding body 2, and the end of the spring 5 away from the vertical plate 20 is fixed on the adjusting nut 7.

[0032] When the measuring instrument is mounted and fixed on the assembly workbench and spans under the gear ring product to be measured, the adjusting nut 7 is rotated to make the adjusting nut 7 squeeze the spring 5, thereby adjusting the compression amount of the spring 5. The thrust of the spring 5 on the adjusting nut 7 is realized to achieve the tightening force, so that the standard gear 3 and the slewing bearing outer teeth or the slewing bearing inner teeth product are kept coupled; when the measuring instrument is mounted and fixed on the assembly workbench and is located on the outer side of the external gear slewing bearing or the inner side of the internal gear slewing bearing, the adjusting nut 7 is rotated to make the adjusting nut 7 away from the spring 5, thereby adjusting the stretching amount of the spring 5. The pulling force of the spring 5 on the adjusting nut 7 makes the sliding body 2 have a tendency to move in the direction away from the mounting body 1, thereby achieving the tightening force on the coupling of the standard gear 3 and the slewing bearing outer teeth or the slewing bearing inner teeth, so as to ensure the coupling effect of the standard gear 3 and the slewing bearing gear ring product.

[0033] Reference Figure 2 and Figure 3 To facilitate measurement of the displacement of the sliding body 2, the measuring device includes a measuring gauge 4 with a stylus. Measuring gauge 4 is fixedly mounted on the mounting body 1. An L-shaped abutment piece 8 is fixedly mounted on the side of the sliding body 2, and the end of the stylus of the measuring gauge 4 contacts the abutment piece 8. Measuring gauge 4 is electrically connected to an external control platform. Specifically, measuring gauge 4 can be an electronic micrometer, a displacement sensor, or the like, without limitation.

[0034] When the installation of the mounting body 1 is completed and the adjusting nut 7 is fully adjusted, the end of the stylus of the measuring gauge 4 is in contact with the abutment piece 8 and is in the initial position. The measured data is the initial value and is sent to the external control platform. During the rotation of the slewing bearing ring gear product, the data detected by the measuring gauge 4 is sent to the external control platform. The difference with the initial value can be calculated to obtain the moving distance of the center of the standard gear 3, and then the change in the double meshing center distance can be obtained.

[0035] Reference Figure 3In order to be able to replace the standard gear 3 according to different types of slewing ring gear products, the standard gear 3 and the bearing seat 21 are detachably fixed by bolts; and a strip groove 25 for the sliding bearing seat 21 is opened on the sliding body 2. The length direction of the strip groove 25 is parallel to the length direction of the sliding body 2. The bearing seat 21 is fixed to the sliding body 2 by bolts, which helps to adjust the position of the standard gear 3.

[0036] Reference Figure 2 and Figure 3 In order to expand the applicable scenarios, the side of the sliding body 2 close to the standard gear 3 extends out of the mounting body 1, so that when the distance between the lower surface of the slewing ring gear and the base 14 is less than the height of the sliding body 2, the measuring instrument can be placed inside the internal gear slewing bearing product or outside the external gear slewing bearing product for measurement, and the mounting body 1 is not likely to interfere with the measured gear ring product.

[0037] Reference Figure 2 and Figure 3 Furthermore, the distance from the axis of the standard gear 3 to the side of the sliding body 2 away from the mounting body 1 is smaller than the outer diameter of the standard gear 3, so that the outer edge of the standard gear 3 extends out of the sliding body 2. When the measuring instrument is placed inside the internal gear slewing bearing product or outside the external gear slewing bearing product for measurement, the sliding body 2 will not interfere with the slewing bearing product.

[0038] The implementation principle of Example 1 of the present application is as follows: after the assembly of the slewing bearing ring gear product is completed, taking the internal gear slewing bearing product as an example, the mounting body 1 of the measuring instrument is passed from the inner side of the slewing bearing ring gear product through the bottom of the inner gear ring product to be measured, and extended outward, so that the length direction of the mounting body 1 and the sliding direction of the sliding body 2 are arranged along the radial direction of the slewing bearing ring gear product, and then the standard gear 3 is meshed with the gear ring product to be measured, and the spring 5 is in a compressed state, and then the mounting body 1 is fixed to the base 14 of the assembly workbench by bolts, and then the adjusting nut 7 is turned to adjust the compression amount of the spring 5 to implement the tightening force to ensure that the standard gear 3 is meshed with the slewing bearing ring gear. At this time, the measuring needle of the measuring gauge 4 is in abutment with the abutment plate 8 in the initial state, and the measured value is the initial value.

[0039] Then, the driving motor 16 on the assembly workbench drives the power arm 17 to make the inner ring and the gear ring of the slewing bearing rotate synchronously, and the gear ring product to be tested drives the standard gear 3 to rotate. Due to the coupling effect of the gear ring product to be tested and the standard gear 3, the gear ring product to be tested will experience radial jump during the rotation process, and the gear ring product to be tested will transfer the movement amount to the standard gear 3, so that the standard gear 3 and the sliding body 2 will move back and forth in the radial direction of the slewing bearing. The moving distance of the sliding body 2 and the standard gear 3 can be measured by the measuring needle of the measuring table 4, and then the change in the double meshing center distance can be obtained. In this application, there is no need to move the assembled slewing bearing gear ring product to be tested during measurement. Instead, the measuring instrument only needs to be installed on the assembly workbench of the slewing bearing gear ring product to complete the measurement operation, thereby facilitating the measurement of large and heavy slewing bearing gear ring products with an outer diameter greater than 800 mm. It is convenient, practical, and has a wide range of applications.

[0040] Example 2: Reference Figure 4 and Figure 5 The difference between the embodiment of the present application and embodiment 1 is that a connecting plate 10 is fixed to the end of the sliding body 2 away from the standard gear 3, and a slide 11 is slidably sleeved on the connecting plate 10. The sliding direction of the slide 11 is parallel to the sliding direction of the sliding body 2, and the measuring meter 4 is fixed on the slide 11; a fixed platform 12 is fixed on the mounting body 1, and a screw 13 is threaded through the slide 11. The screw 13 is located between the fixed platform 12 and the connecting plate 10, and the rotation axis of the screw 13 is parallel to the arrangement direction of the fixed platform 12 and the connecting plate 10. Fixing parts are fixed at both ends of the screw 13, and the fixing parts are used to fix the screw 13 relative to the corresponding connecting plate 10 or the corresponding fixed platform 12.

[0041] Reference Figure 4 and Figure 5 Specifically, the fixing member includes a suction cup 22, which is used to absorb and fix to the corresponding connecting plate 10 or the corresponding fixing platform 12. When the suction cup 22 at one end of the screw 13 is attached to the connecting plate 10, the suction cup 22 at the other end is separated from the fixing platform 12; when the suction cup 22 at one end of the screw 13 is attached to the fixing platform 12, the suction cup 22 at the other end is separated from the connecting plate 10. In other embodiments, the suction cup 22 can be replaced by a tightening bolt head.

[0042] Reference Figure 4 and Figure 5A fixing groove 23 is provided on the side of the fixed platform 12 near the slide 11. The cross-section of the fixing groove 23 is T-shaped, and the screw 13 slides through the fixing groove 23. The length of the fixing groove 23 is parallel to the sliding direction of the sliding body 2, thus providing sliding of the slide 11. A disengagement groove 24 is provided on the inner wall of the slide 11. The end of the screw 13 near the connecting plate 10 is located in the disengagement groove 24, thus providing space for the suction cup 22 on the screw 13 to disengage from the connecting plate 10. To facilitate the rotation of the screw 13, a rotating handle is provided on the fixed sleeve of the screw 13.

[0043] The implementation principle of Example 2 of the present application is as follows: when the mounting body 1 is still in the adjustment process, the rotating handle on the screw 13 is rotated so that the suction cup 22 on the screw 13 is adsorbed and fixed to the connecting plate 10, and the suction cup 22 at the other end is separated from the fixed platform 12. At this time, the measuring table 4 can move synchronously with the sliding body 2 to ensure that the measuring needle can maintain an appropriate contact depth with the abutment piece 8 on the sliding body 2, and the measuring needle and the abutment piece 8 will not contact too deeply or separate due to the change in the position of the sliding body 2; when the mounting body 1 is installed and the adjusting nut 7 is adjusted, the screw 13 is rotated in the opposite direction so that the suction cup 22 at one end of the screw 13 is separated from the connecting plate 10, and the suction cup 22 at the other end is adsorbed and fixed to the fixed platform 12, so that the measuring table 4 is relatively fixed to the mounting body 1. During the rotation of the gear ring product being measured, the reciprocating movement value of the sliding body 2 can be measured by the measuring table 4, and the change in the double meshing center distance can be obtained.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
