Description

Technical Field

[0001] The present disclosure relates to the technical field of bearing processing, and in particular to a bearing running-in machine and a bearing running-in device. Background Art

[0002] As a core component of modern mechanical transmission systems, bearings play a crucial role in securing shaft positions and reducing load friction. During the operation of various types of mechanical equipment, when different parts move relative to each other around the shaft, bearings, through their unique structural design, effectively reduce mechanical friction during power transmission, ensuring stable operation of the shaft system. Bearings can be divided into two categories, rolling bearings and sliding bearings, based on the differences in the friction properties of the moving elements. They are widely used in key industries such as automotive manufacturing, aerospace, and rail transportation.

[0021] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0022] Combine Figure 1 and Figure 2As shown, the bearing running-in machine provided by the embodiment of the present disclosure includes a frame 1, multiple running-in seats 2, a transmission mechanism and a clamping mechanism. The multiple running-in seats 2 are arranged in sequence along the length direction X of the frame 1; the transmission mechanism includes a driving wheel 31, a driven wheel 32 and a driving motor 33. The driving wheel 31 and the driven wheel 32 are respectively arranged at both ends of the multiple running-in seats 2 along the length direction X of the frame 1. The driving wheel 31 and the driven wheel 32 are connected by a transmission belt 34. The output end of the driving motor 33 is connected to the driving wheel 31; the clamping mechanism includes a first driving member 41, a movable plate 42, a second driving member 43, a pressing plate 44 and multiple pressing components. The first driving member 41 is arranged on the frame 1, the first driving member 41 is arranged on the frame 1, and the second driving member 43 is arranged on the frame 1. The driving end of the component 41 is connected to the movable plate 42 to drive the movable plate 42 to move along the width direction Y of the frame 1. The second driving component 43 is arranged on the movable plate 42. The driving end of the second driving component 43 is connected to the pressing plate 44 to drive the pressing plate 44 to move along the height direction Z of the frame. Multiple pressing assemblies are arranged on the pressing plate 44, and the multiple pressing assemblies are used to correspond one-to-one with multiple running-in seats. Among them, when the clamping mechanism presses the outer ring 72 of the bearing, the inner shaft 71 of the bearing abuts against the transmission belt 34. When the clamping mechanism presses the outer ring 72 of the bearing through the pressing assembly, the inner shaft 71 of the bearing abuts against the transmission belt 34. This design can ensure that the bearing always maintains a stable stress state during the running-in process. In this embodiment, multiple running-in seats 2 are arranged in sequence along the length direction X of the frame 1. In conjunction with the design of the driving wheel 31, the driven wheel 32 and the transmission belt 34 in the transmission mechanism, multiple bearings can be run-in at the same time. Compared with the traditional method of installing bearings on the spindle of an ordinary lathe for individual running-in, the running-in time and the frequency of manual operations are greatly reduced, which meets the needs of mass production and significantly improves the production efficiency of bearing running-in. The first driving member 41 of the clamping mechanism can drive the movable plate 42 to move along the width direction Y of the frame 1, and the second driving member 43 drives the pressing plate 44 to move along the height direction Z. This multi-dimensional adjustment design can flexibly adjust the position of the pressing assembly and enhance the adaptability of the running-in machine to different types of bearings. Through the automated control of components such as the drive motor 33, the first driving member 41 and the second driving member 43, the operator does not need to frequently manually adjust the bearing position and the clamping force. The operator only needs to set and monitor the parameters to complete the bearing running-in operation. This not only reduces the labor intensity of the operator, but also reduces human operational errors, further improving the reliability and safety of production.

[0023] The first driving member 41 and the second driving member 43 may both be cylinders.

[0024] In some specific embodiments, a slide rail 45 and a slider 46 are further included. The slide rail 45 is disposed on the frame 1 and extends along the width direction Y. The slider 46 slidably engages with the slide rail 45 and is connected to the movable plate 42. The slide rail 45 is disposed along the width direction Y on the frame 1 and connected to the movable plate 42 via the slider 46, forming a high-precision linear guide system. This improves the movement of the movable plate 42 along the Y direction, ensuring accuracy when adjusting the position of the press-fit assembly.

[0025] In some specific embodiments, a temperature detection device 6 is also included. The temperature detection device 6 includes a wire and a temperature probe connected to the end of the wire. The running-in seat 2 is provided with a through hole. The temperature probe is extended from the through hole and is used to abut against the bearing. The temperature detection device 6 directly abuts against the bearing through the temperature probe, and can collect surface temperature data during the running-in process of the bearing in real time, thereby ensuring the safety of the running-in process and preventing overheating damage to the bearing. Temperature data can serve as an important diagnostic basis during the running-in process of the bearing. When problems such as abnormal wear and poor assembly occur in the bearing, it is usually accompanied by an abnormal increase in temperature. By analyzing the temperature data, it can assist in determining the cause of the fault, help technicians quickly locate the problem, shorten the troubleshooting time, and reduce equipment maintenance costs.

[0026] In some specific embodiments, a speed sensor is further included and disposed on the running-in seat 2. The speed sensor collects real-time speed data of the bearing inner shaft 71 and, combined with a PID control algorithm, suppresses speed fluctuations to within ±0.5%. This improves the running-in speed accuracy of the bearing and effectively avoids uneven wear caused by unstable speed.

[0027] In some specific embodiments, the pressing assembly includes a guide rod 51, a spring 52, a limit block 53 and a pressure block 54; the limit block 53 and the pressure block 54 are respectively arranged at both ends of the guide rod 51; the pressing plate 44 is provided with a mounting hole, the guide rod 51 slides with the mounting hole, the limit block 53 and the pressure block 54 are respectively located on both sides of the pressing plate 44, and the pressure block 54 is used to be arranged corresponding to the running-in seat 2; the two ends of the spring 52 are respectively connected to the pressing plate 44 and the guide rod 51. The elastic design of the pressing assembly provides adaptive clamping force control for the running-in of the bearing, which significantly improves the running-in quality and the versatility of the equipment. The maximum compression amount of the spring 52 (can limit the maximum pressure of the pressure block 54 to avoid damage to the bearing or equipment due to overload.

[0028] The preload force of the spring 52 can be set by adjusting the position of the limit block 53. When there is a machining error on the surface of the bearing outer ring 72, the spring 52 can automatically expand and contract to compensate, so that the pressure block 54 always maintains uniform contact with the bearing outer ring 72.

[0029] In some specific embodiments, the guide rod 51 is provided with a fixed block 55, which is fixed to the middle area in the length direction of the guide rod 51. The fixed block 55 is located on the side of the pressing plate 44 away from the limit block 53, and the two ends of the spring 52 are respectively connected to the pressing plate 44 and the fixed block 55. The fixed block 55 is located in the middle area in the length direction of the guide rod 51, which makes the force points at both ends of the spring 52 more symmetrical and changes the way the force is transmitted. During the pressing process, the elastic force generated by the spring 52 is evenly transmitted to the guide rod 51 through the fixed block 55, reducing the bending deformation of the guide rod 51 caused by uneven force. During the running-in process, the vibration and rotation of the bearing may cause the lateral swing of the spring 52, affecting the pressing effect. The fixed block 55 plays a role in limiting and supporting the spring 52.

[0030] In some specific embodiments, the running-in seat 2 is provided with a first arcuate groove 21, the shape of which is adapted to the shape of the bearing outer ring 72, and the pressure block 54 is provided with a second arcuate groove 541, which is arranged correspondingly to the first arcuate groove 21. The double-arc-groove structure evenly distributes the pressure applied by the pressure block 54 to the surface of the bearing outer ring 72, which can improve the uniformity of pressure distribution compared to a planar contact method. The first arcuate groove 21 of the running-in seat 2 is highly adapted to the shape of the bearing outer ring 72, and the second arcuate groove 541 of the pressure block 54 is arranged correspondingly thereto, forming a wrap-around fitting structure. This design increases the contact area between the bearing outer ring 72 and the arcuate groove, effectively avoiding local wear caused by poor contact during the running-in process, ensuring that the bearing is evenly stressed during the running-in process, and improving the overall performance and service life of the bearing after the running-in process.

[0031] In some specific embodiments, the movable plate 42 is provided with a guide hole, in which a guide rod 47 is provided, and the guide rod 47 is connected to the pressing plate 44. This can enhance the vertical guide accuracy, ensure the verticality of the pressing, improve the fitting accuracy, and ensure the running-in effect.

[0032] In some specific embodiments, the running-in base 2 is provided with a rotating shaft, which is rotatably connected to the running-in base 2 . The rotating shaft is provided with a roller 22 . The transmission belt 34 is disposed on the upper surface of the roller 22 . The plurality of rollers 22 are sequentially arranged along the length direction X. This can reduce tension loss in the transmission belt 34 . The plurality of rollers 22 are sequentially arranged along the length direction X, so that the transmission belt 34 maintains a stable tension state during operation, thereby improving transmission efficiency.
