Description

Technical Field

[0001] This utility model relates to the technical field of bearing testing equipment, and more specifically, it relates to an impact resistance testing device for bearing testing. Background Technology

[0002] Bearings are precision mechanical components widely used in various rotating equipment. Their main function is to support the rotating shaft of machinery, reduce friction between the shaft and the support, and withstand radial, axial, or combined loads to ensure smooth and efficient equipment operation. There are many types of bearings, including ball bearings, roller bearings, and plain bearings, each with its unique structure and application scenarios. For example, ball bearings are typically used in light-load, high-speed applications, while roller bearings are more suitable for heavy-load applications. The performance of bearings has a crucial impact on the operating efficiency and service life of mechanical equipment; therefore, high-quality bearings often require strict quality control and precision machining to ensure stable and reliable operation under various working conditions.

[0003] Quality control of bearings includes impact testing, such as the guide bearing impact testing device disclosed in CN221571804U, which uses a falling impact hammer to impact the bearing surface. However, the bearing in the above patent is a static test, which differs from the impact encountered by bearings in actual use, and the test results are not accurate enough. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an impact resistance testing device for bearing testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an impact resistance testing device for bearing testing, comprising a base and an impact assembly;

[0006] A clamping frame is fixedly connected to the base, and a bidirectional lead screw is rotatably connected to the clamping frame. One end of the bidirectional lead screw is connected to the output shaft of a first motor via a coupling. The first motor is mounted on the clamping frame. A vertical rod is fixedly connected to the clamping frame, and two clamping plates are slidably connected to the vertical rod. The two clamping plates are threaded to both ends of the bidirectional lead screw, respectively.

[0007] An electric cylinder is mounted on the base, a drive frame is fixedly connected to the piston rod of the electric cylinder, a second motor is mounted on the drive frame, and a drive wheel is fixedly connected to the output shaft of the second motor.

[0008] The striking assembly is mounted on the base and is used to strike the bearing.

[0009] Preferably, the striking assembly includes a third motor, a turntable, springs, and balls. The third motor is mounted on a base, and a turntable is fixedly connected to the output shaft of the third motor. Multiple springs are fixedly connected to the turntable, and balls are fixedly connected to the ends of the multiple springs away from the turntable.

[0010] Preferably, a plurality of guide rods are slidably connected to the drive frame, and one end of each of the guide rods is fixedly connected to the base.

[0011] Preferably, a rubber ring is fixedly connected to the drive wheel, and the rubber ring rubs against the outer ring sidewall of the bearing.

[0012] Preferably, rubber pads are fixedly connected to the two clamping plates respectively, and both rubber pads rub against the inner ring sidewall of the bearing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] After the bearing is supported and fixed by two clamping plates, the drive frame is pushed up by an electric cylinder. The drive wheel follows the drive frame up and comes into contact with the outer ring of the bearing. Then, the second motor drives the drive wheel to rotate, which in turn drives the outer ring of the bearing to rotate. The outer ring of the bearing is then struck by the impact component, which is more in line with the impact encountered by the bearing in actual use, and the test results are more accurate.

[0024] Reference Figures 1 to 3 This utility model provides a technical solution: an impact resistance testing device for bearing testing, including a base 1 and an impact assembly;

[0025] A clamping frame 2 is fixedly connected to the base 1. A bidirectional lead screw 3 is rotatably connected to the clamping frame 2. One end of the bidirectional lead screw 3 is connected to the output shaft of a first motor 4 via a coupling. The first motor 4 is mounted on the clamping frame 2. A vertical rod 5 is fixedly connected to the clamping frame 2. Two clamping plates 6 are slidably connected to the vertical rod 5. The two clamping plates 6 are threadedly connected to both ends of the bidirectional lead screw 3, respectively.

[0026] like Figure 1 and Figure 3 The inner ring of the bearing is fitted onto two clamping plates 6. The first motor 4 drives the bidirectional lead screw 3 to rotate. The bidirectional lead screw 3 drives the two clamping plates 6 to move away from each other along the vertical rod 5. The two clamping plates 6 can then support and fix the bearing.

[0027] An electric cylinder 7 is mounted on the base 1. A drive frame 8 is fixedly connected to the piston rod of the electric cylinder 7. A second motor 9 is mounted on the drive frame 8. A drive wheel 10 is fixedly connected to the output shaft of the second motor 9.

[0028] like Figure 1 When the bearing is supported and fixed by the two clamping plates 6, the drive frame 8 is pushed up by the electric cylinder 7. The drive wheel 10 follows the drive frame 8 and rises and comes into contact with the outer ring of the bearing. Then the second motor 9 drives the drive wheel 10 to rotate, and the drive wheel 10 can drive the outer ring of the bearing to rotate.

[0029] The striking assembly is mounted on the base 1 and is used to strike the bearing.

[0030] By striking the outer ring of the bearing with a striking component, the impacts encountered by the bearing during actual use are more consistent with those experienced by the bearing, resulting in more accurate test results.

[0031] Specifically, the striking assembly includes a third motor 11, a turntable 12, a spring 13, and a ball 14. The third motor 11 is mounted on the base 1. The turntable 12 is fixedly connected to the output shaft of the third motor 11. Multiple springs 13 are fixedly connected to the turntable 12. A ball 14 is fixedly connected to one end of each of the multiple springs 13 away from the turntable 12.

[0032] like Figure 1 The output shaft of the third motor 11 can drive the turntable 12 to rotate. The turntable 12 drives the balls 14 to rotate through the spring 13. Multiple balls 14 can continuously strike the bearing, resulting in a higher striking frequency and higher testing efficiency.

[0033] Specifically, a plurality of guide rods 15 are slidably connected to the drive frame 8, and one end of each guide rod 15 is fixedly connected to the base 1, such as... Figure 1This makes the drive frame 8 more stable during the lifting and lowering process.

[0034] Specifically, a rubber ring 16 is fixedly connected to the drive wheel 10. The rubber ring 16 rubs against the outer ring sidewall of the bearing, thereby increasing the friction between the drive wheel 10 and the bearing.

[0035] Specifically, rubber pads 17 are fixedly connected to the two clamping plates 6 respectively. Both rubber pads 17 rub against the inner ring sidewall of the bearing, thereby increasing the friction between the clamping plates 6 and the bearing.

[0036] Working principle: The inner ring of the bearing is fitted onto two clamping plates 6. The first motor 4 drives the double-acting screw 3 to rotate, which in turn moves the two clamping plates 6 along the vertical rod 5 in a direction away from each other, thus supporting and fixing the bearing. The electric cylinder 7 pushes the drive frame 8 to rise, and the drive wheel 10 rises with the drive frame 8 and comes into contact with the outer ring of the bearing. The second motor 9 then drives the drive wheel 10 to rotate, which in turn drives the outer ring of the bearing to rotate. The output shaft of the third motor 11 drives the turntable 12 to rotate, and the turntable 12 drives the balls 14 to rotate through the spring 13. Multiple balls 14 can then continuously strike the bearing for testing.

[0037] It should be noted that all electrical components appearing in this application are connected to an external main controller and 220V AC mains power. The main controller can be a processor, alarm module, or drive module, etc., to control conventional known devices. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as bolts, rivets, and welding, which are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
