Abstract
Description
Technical Field
[0001] This invention relates to the field of testing tooling technology, and more specifically, to a method and system for testing outer ring components. Background Technology
[0002] After the outer ring of a bearing (such as a bearing outer ring or a slewing bearing outer ring) is machined, its machining accuracy and assembly surface accuracy need to be tested. Typically, the runout value of the outer peripheral wall and end face of the bearing outer ring is measured to evaluate the machining accuracy and assembly surface accuracy. Existing testing methods often involve fixing the bearing outer ring to a support body, then applying a uniform force to press another support body against the inner wall of the outer ring. Both supports have circumferentially arranged rolling elements, which support and fix the bearing inner ring. Simultaneously, the runout value is measured by driving the outer ring to rotate and using a displacement sensor.
[0003] To ensure the stability of the detection benchmark, the rolling elements need to form a uniform and continuous contact with the inner wall of the outer ring. However, due to potential roundness errors, rolling element installation gaps, or orientation deviations on the inner wall of the outer ring, directly applying a uniform force to make the rolling elements abut against the inner wall often fails to achieve uniform contact throughout the circumference, leading to unstable support. Some solutions attempt to adjust the rolling element position manually or with a single feed, but this is cumbersome, inefficient, and makes it difficult to guarantee that the upper and lower rolling elements simultaneously form a reliable contact with the inner wall. Therefore, how to achieve a stable, continuous, and coordinated support contact between the upper and lower sets of rolling elements and the inner wall of the outer ring to improve the measurement accuracy of runout detection has become a pressing technical problem in this field. Summary of the Invention

[0025] Based on a preset axial distance between the upper support component and the outer ring component, the outer ring component is driven to detach from the lower support component.
[0026] In a second aspect, the present invention provides an outer ring component detection system, applied to any optional outer ring component detection method of the first aspect, the outer ring component detection system comprising:
[0027] Outer ring components;
[0028] The lower support assembly is mounted on the base assembly; the lower support assembly is provided with a plurality of lower rolling elements that are circumferentially connected to the outer peripheral wall of the lower support assembly.
[0029] An upper support assembly is mounted on the base assembly and is positioned opposite to the lower support assembly, wherein the lower support assembly and the upper support assembly are concentrically positioned; the upper support assembly is provided with a plurality of upper rolling elements that are circumferentially connected to the outer peripheral wall of the upper support assembly;
[0030] A detection unit is mounted on the base assembly. The outer ring assembly detection system includes a detection state. In the detection state, the outer ring assembly is sleeved on the lower support assembly, and the lower rolling element of the lower support assembly at least partially abuts against the inner wall of the outer ring assembly. The upper support assembly is driven to move to the first detection position according to a first preset rule, and the outer ring assembly rotates according to a first rotation rule. The lower rolling element and the outer ring assembly have a first mounting position. The upper support assembly is driven to move according to a second preset rule while the outer ring assembly is driven to rotate according to a second rotation rule. The upper rolling element and the outer ring assembly have a second mounting position. Based on the first and second mounting positions, the detection unit abuts against the outer peripheral wall and / or end face of the outer ring assembly, and the outer ring assembly is driven to rotate according to a third rotation rule. The detection unit measures the runout value of the outer peripheral wall and / or end face.
[0031] Optionally, the upper support assembly includes an upper connecting body and an upper central body. The upper connecting body is connected to the base assembly; the upper central body is connected to the upper connecting body; and multiple upper rolling elements are circumferentially connected to the outer peripheral wall of the upper central body.
[0032] Optionally, the lower support assembly includes a lower connecting body and a lower center body. The lower connecting body is connected to the base assembly; the lower center body is connected to the lower connecting body; and multiple lower rolling elements are circumferentially connected to the outer peripheral wall of the lower center body.
[0033] To address the problem of how to ensure stable and continuous support contact between the upper and lower sets of rolling elements and the inner circumferential wall of the outer ring, thereby improving the measurement accuracy of runout detection, this invention offers the following advantages:
[0034] 1. With the lower rolling element at least partially abutting against the inner wall of the outer ring assembly, the upper support assembly is driven to move to the first detection position according to the first preset rule, so that the upper rolling element and the inner peripheral wall of the outer ring assembly maintain a preset gap, thereby providing an initial limit for the subsequent rotation of the outer ring assembly according to the first rotation rule, preventing the outer ring assembly from detaching from the lower support assembly during rotation, causing damage to the outer ring assembly and repetition of the operation;
[0035] 2. Based on the outer ring assembly rotating according to the first rotation rule, the lower rolling element automatically adjusts its posture under the action of rotation and forms a stable first installation position with the outer ring assembly, which provides a basis for the upper rolling element to form a continuous contact with the outer ring assembly, and at the same time improves the measurement accuracy of the subsequent detection component runout value;
[0036] 3. While driving the upper support component to move according to the second preset rule, the outer ring component is driven to rotate according to the second rotation rule. Under the synergistic effect of movement and rotation, the upper rolling element automatically fits against the inner circumferential wall of the outer ring component to obtain the second installation position. This forms a continuous and reliable contact state on both the upper and lower sides. Based on the first and second installation positions, the measurement accuracy of the detection component is improved, and it is avoided that the upper rolling element gets stuck due to posture problems when it comes into contact with the inner wall of the outer ring component, which would cause damage to the inner wall of the outer ring component and affect the accuracy of subsequent runout value measurement.

[0049] Example 1
[0050] This embodiment provides a method for detecting outer ring components. Please refer to [link / reference]. Figure 1 This includes the following steps S10-S40:
[0051] Step S10: Based on the fact that the lower rolling element 33 of the lower support component 30 at least partially abuts against the inner wall of the outer ring component 40, the upper support component 20 is driven to move to the first detection position according to a first preset rule; wherein, the first detection position includes a preset gap between the upper rolling element 24 of the upper support component 20 and the inner peripheral wall of the outer ring component 40; a plurality of lower rolling elements 33 are movably connected to the outer peripheral wall of the lower support component 30 in the circumferential direction; a plurality of upper rolling elements 24 are movably connected to the outer peripheral wall of the upper support component 20 in the circumferential direction.
[0052] Step S20: Based on the outer ring assembly 40 rotating according to the first rotation rule, the lower rolling body 33 and the outer ring assembly 40 have a first mounting position;
[0053] In step S30, while driving the upper support component 20 to move according to the second preset rule, the outer ring component 40 is driven to rotate according to the second rotation rule, and the upper rolling body 24 and the outer ring component 40 have a second mounting position.
[0054] In step S40, based on the first installation position and the second installation position, the detection component abuts against the outer peripheral wall and / or end face of the outer ring component 40, drives the outer ring component 40 to rotate according to the third rotation rule, and the detection component measures the runout value of the outer peripheral wall and / or end face.
[0055] Please refer to Figure 1Both the lower support assembly 30 and the upper support assembly 20 are mounted on the base assembly 10 and are positioned opposite each other on the base assembly 10. The central axes of the lower support assembly 30 and the upper support assembly 20 are collinear. The upper support assembly 20 is fixedly mounted on the base assembly 10, while the lower support assembly 30 is positioned opposite to the upper support assembly 20 and is movable relative to the base assembly 10 and the upper support assembly 20. That is, in the detection state, the upper support assembly 20 can move in a direction closer to or farther from the lower support assembly 30 to achieve positioning or fixed support for the outer ring assembly 40.
[0056] Specifically, refer to Figure 2 , Figure 4 and Figure 5 The lower support assembly 30 includes a lower connecting body 31 and a lower central body 32. The lower connecting body 31 is connected to the base assembly 10; the lower central body 32 is connected to the lower connecting body 31. Multiple lower rolling elements 33 are movably connected circumferentially to the outer peripheral wall of the lower central body 32. The lower rolling elements 33 and the upper rolling elements 24 are, for example, roller-shaped. The lower central body 32 is a cylinder with a rectangular cross-section in the vertical direction. The multiple lower rolling elements 33 are movably connected circumferentially to the inclined outer peripheral wall of the lower central body 32, such that the central axis of the multiple lower rolling elements 33 intersects with the central axis of the lower central body 32. The lower central body 32 has, for example, multiple mounting grooves on its inclined outer peripheral wall along the circumferential direction, and the lower rolling elements 33 are installed in these grooves. The width of the mounting groove along the circumferential direction and the length along the axial direction are both greater than the diameter and length of the lower rolling elements 33, creating a gap between the outer peripheral wall of the lower rolling elements 33 and the inner wall of the mounting groove. The lower rolling elements 33 can achieve rolling or adjust their posture based on this gap. In one example, a retainer is provided on the lower center body 32, and multiple lower rolling elements 33 are mounted on the retainer. The retainer is provided with multiple mounting slots that have the same structure and function as the mounting slots mentioned above. This will not be described in detail here, but the specific application shall prevail.
[0057] Specifically, the lower support assembly 30 includes an upper connecting body 22 and an upper central body 23. The upper connecting body 22 is connected to the base assembly 10; the upper central body 23 is connected to the upper connecting body 22; a plurality of upper rolling elements 24 are circumferentially connected to the outer peripheral wall of the upper central body 23. The upper central body 23 is a cylinder with a rectangular cross-section in the vertical direction. The plurality of upper rolling elements 24 are circumferentially connected to the inclined outer peripheral wall of the upper central body 23, such that the central axis of the plurality of upper rolling elements 24 intersects the central axis of the upper central body 23, and the upper central body 23 and the lower central body 32 are concentric. The upper central body 23 has, for example, a plurality of mounting grooves on the inclined outer peripheral wall in the circumferential direction, and the upper rolling elements 24 are installed in the mounting grooves; wherein the width of the mounting groove in the circumferential direction and the length in the axial direction are both greater than the diameter and the length in the axial direction of the upper rolling element 24, so that there is a gap between the outer peripheral wall of the upper rolling element 24 and the inner wall of the mounting groove, and the upper rolling element 24 can achieve rolling or adjustment of its own posture based on the gap. In one example, a retainer is provided on the upper central body 23, and multiple upper rolling elements 24 are mounted on the retainer. The retainer is provided with multiple mounting slots that have the same structure and function as the mounting slots mentioned above. This will not be described in detail here, but the specific application shall prevail.
[0058] For details, please refer to Figure 6 and Figure 7 The outer ring assembly 40 includes an outer ring body 41, and a first raceway 42 and a second raceway 43 disposed within the outer ring body 41. The first raceway 42 and the second raceway 43 are arranged sequentially along the axial direction. In the detection state, the upper rolling element 24 is located within the first raceway 42, and the lower rolling element 33 is located within the second raceway 43. The specific arrangement depends on the actual application.
[0059] Before step S10, the method further includes fitting the outer ring component 40 onto the lower center body 32 of the lower support component 30, such that the inner peripheral wall of the outer ring component 40 adheres to or at least partially abuts against the lower rolling body 33 of the lower center body 32 based on its own weight, thereby achieving at least partial abutment between the lower rolling body 33 of the lower support component 30 and the inner wall of the outer ring component 40, and simultaneously achieving adjustment of the posture of the multiple lower rolling bodies 33, with at least some of the lower rolling bodies 33 continuously abutting against the inner peripheral wall of the outer ring component 40 along the axial direction.
[0060] Further, the movement of the drive support component 20 to the first detection position according to the first preset rule in step S10 includes:
[0061] Get the first itinerary;
[0062] The upper support component 20 is driven to move along the detection direction for a first stroke, and the upper support component 20 is located at the first detection position.
[0063] Understandably, the upper support component 20 presses against the outer ring component 40 with a fixed stroke. When the upper support component 20 moves for the first stroke, there is a preset gap between the upper rolling element 24 of the upper support component 20 and the inner peripheral wall of the outer ring component 40. Then, it moves for the second stroke to complete the pressing of the upper support component 20 against the outer ring component 40.
[0064] Furthermore, in step S10, after the lower rolling element 33 has contacted the inner wall of the outer ring assembly 40, the upper rolling element 24 approaches but does not contact the inner wall with a preset gap, forming a pre-limited state of upward floating and downward support. This preset gap is used to prevent the outer ring assembly 40 from axial movement or radial swaying due to centrifugal force or vibration during subsequent rotation, and to prevent the outer ring assembly 40 from falling off the lower support assembly 30, thereby protecting the outer ring assembly 40 and the equipment. The specific value of the preset gap is not limited, and depends on the actual application. Compared to the related technologies where the outer ring is fitted onto the lower center body 32 and provides a directional and uniform force to the lower center body 32, pressing both the upper rolling element 24 and the lower rolling element 33 together to abut against the inner peripheral wall of the outer ring assembly 40, this embodiment eliminates the risk of point contact or jamming caused by the roundness error of the inner peripheral wall or the misalignment of the upper rolling element 24 and the lower rolling element 33. It also provides a safety space for the subsequent adaptive fitting of the upper rolling element 24 and provides a foundation for improving the accuracy of the runout value of the detection component.
[0065] In step S20, the first installation position includes the lower rolling element 33 abutting against the inner peripheral wall of the outer ring assembly 40, and the third abutting line of the lower rolling element 33 and the fourth abutting line of the inner peripheral wall of the outer ring assembly 40 being parallel to each other along the axial direction; the third abutting line is located on the outer peripheral wall of the lower rolling element 33 along the axial direction, and the fourth abutting line is located on the inner peripheral wall of the outer ring assembly 40 along the axial direction.
[0066] Specifically, based on the first rotation rule, the outer ring assembly 40 is driven to rotate along its own axis. Utilizing the rolling friction between the lower rolling element 33 and the inner peripheral wall of the outer ring assembly 40, the movable lower rolling element 33 automatically adjusts its circumferential attitude and axial deflection angle around the axis until the third abutment line of the lower rolling element 33 and the fourth abutment line of the inner peripheral wall of the outer ring assembly 40 are parallel to each other axially, forming a uniform and continuous line contact around the entire circumference. By using rotation rather than the axial forceful pushing method used in related technologies to achieve contact with the lower rolling element 33, scratches on the inner wall or deformation of the rolling element caused by hard pressing are avoided, thus protecting the quality of the inner peripheral wall of the outer ring assembly 40. Furthermore, after obtaining the first installation position, the lower rolling element 33 and the inner peripheral wall of the outer ring assembly 40 provide stable rolling support, and the outer ring assembly 40 exhibits no axial movement or radial wobble during rotation, providing a precise and reliable reference surface for the subsequent installation and runout detection of the upper rolling element 24.
[0067] Furthermore, the first rotation rule includes:
[0068] Provide the primary driving force;
[0069] The outer ring assembly 40 is driven to rotate along its axis by a first driving force.
[0070] Understandably, based on a relatively small initial driving force and low torque drive, the outer ring assembly 40 rotates smoothly, and the movable lower rolling element 33 can slightly oscillate or rotate within the mounting groove on the outer peripheral wall, automatically seeking the lowest energy posture that makes the third and fourth abutment lines parallel along the axial direction, thereby forming uniform contact. Furthermore, based on the first detection position in step S10, the outer ring assembly 40 vibrates slightly during rotation, further assisting in ensuring the third and fourth abutment lines are parallel along the axial direction when they abut.
[0071] In step S30, while driving the upper support component 20 to move according to the second preset rule, the outer ring component 40 is driven to rotate according to the second rotation rule, and the upper rolling element 24 and the outer ring component 40 have a second mounting position, including the following steps S31-S32:
[0072] Step S31: Drive the upper support assembly 20 to move until the upper rolling body 24 at least partially abuts against the inner wall of the outer ring assembly 40, and simultaneously drive the outer ring assembly 40 to rotate according to the second rotation rule; wherein, the second rotation rule includes converting the first driving force into the second driving force for rotation, and the second driving force is greater than the first driving force; the second preset rule includes the upper support assembly 20 moving at a constant speed and continuously for a second stroke until the upper rolling body 24 at least partially abuts against the inner wall of the outer ring assembly 40, wherein, the second stroke = fixed stroke - first stroke.
[0073] Step S32: Based on the rotation of the outer ring assembly 40 and the adjustment of the posture of the upper rolling element 24, the upper rolling element 24 and the outer ring assembly 40 have a second mounting position; wherein, the second mounting position includes the upper rolling element 24 abutting against the inner peripheral wall of the outer ring assembly 40, and the first abutting line of the upper rolling element 24 and the second abutting line of the inner peripheral wall of the outer ring assembly 40 being parallel to each other along the axial direction; the first abutting line is located on the outer peripheral wall of the upper rolling element 24 along the axial direction, and the second abutting line is located on the inner peripheral wall of the outer ring assembly 40 along the axial direction.
[0074] Specifically, as the upper support assembly 20 moves to bring the upper rolling element 24 closer to and into contact with the inner wall, the outer ring assembly 40 rotates with a second driving force greater than the first driving force. This coordinated movement of moving and rotating causes the upper rolling element 24 to exhibit a rolling tendency at the moment of contact, automatically correcting the axial deflection angle of the upper rolling element 24. This avoids the problem in related technologies where, when moving first and then rotating or when pressing in axially, the upper rolling element 24 may make point or edge contact due to incorrect posture, leading to jamming and scratching of the inner wall.
[0075] Furthermore, through coordinated adjustment, the first abutment line of the upper rolling element 24 and the second abutment line of the inner peripheral wall of the outer ring assembly 40 are parallel to each other along the axial direction, achieving symmetrical and uniform line contact with the lower rolling element 33. Thus, under the combined action of the upper and lower rolling elements, the outer ring assembly 40 is reliably constrained in both the axial and circumferential directions, eliminating redundant degrees of freedom and ensuring smooth and vibration-free rotational motion during the detection state.
[0076] Furthermore, the formation of the second mounting position depends on the second rotation rule. Based on the fact that the second driving force is greater than the first driving force, the upper rolling element 24 transitions from the preset gap state to the abutment state, overcoming static friction as well as the inertia of the upper rolling element 24 itself and the mounting gap. The larger torque ensures that the rotation will not stop or lose its step at the moment of contact, maintaining the continuous rotation of the outer ring assembly 40, thereby providing the upper rolling element 24 with a continuous opportunity for alignment until the first abutment line and the second abutment line are completely parallel, forming a continuous line contact.
[0077] The third rotation rule in step S40 includes:
[0078] The second driving force transforms into the third driving force;
[0079] The outer ring assembly 40 is driven to rotate along its axis by a third driving force; wherein the second driving force is greater than the first driving force and the third driving force.
[0080] Understandably, in step S40, the lower rolling element 33, the upper rolling element 24, and the outer ring assembly 40 maintain the first and second mounting positions, providing stable support in these positions. The driving force is converted into a third driving force, which is less than the second driving force. In this embodiment, the third driving force can be greater than the first driving force. At this time, the outer ring assembly 40 only needs to overcome rolling friction and the slight contact resistance of the detection component. The torque of the third driving force reduces the interference of motor vibration and transmission chain fluctuations on rotational stability, making the runout measurement more accurate. This avoids the impact of the larger torque of the second driving force on the accuracy of the runout value caused by increased motor vibration, and avoids the problem of the smaller torque of the first driving force being unable to overcome resistance. The specific application shall prevail.
[0081] Further, please refer to Figure 2 and Figure 3The base assembly 10 includes a base body 11 and a first drive unit 12; the upper support assembly 20 and the lower support assembly 30 are both disposed on the base body 11; the outer ring assembly 40 also includes a driven ear 44 disposed on the outer peripheral wall of the outer ring body 41, and the first drive unit 12 drives the driven ear 44 to rotate, thereby driving the outer ring assembly 40 to rotate along its own axis. The upper support assembly 20 also includes a second drive unit 21, which drives the upper connecting body 22, the upper center body 23 and the upper rolling body 24 to move a first stroke and / or a second stroke. The detection assembly may include two detection units, which respectively abut against the outer peripheral wall and the end face of the outer ring assembly 40. During rotation, the two detection units can simultaneously obtain two parameters: radial runout and end face runout, thereby improving detection efficiency.
[0082] For example, please refer to Figure 6 The two detection units are respectively abutted against the circumferential runout position 51 and the end face runout position 52 of the outer ring assembly 40 to obtain two parameters: radial runout and end face runout. The specific parameters shall be subject to the actual application.
