Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bearing testing devices, specifically a bearing load-bearing capacity testing device. Background Technology
[0002] Bearings are core components in mechanical systems used to support rotating shafts or moving parts. Their main functions include supporting rotating bodies: bearing the radial or axial loads of rotating mechanical parts to ensure their stable operation; reducing friction: reducing the coefficient of friction during movement through sliding or rolling contact to improve efficiency; and ensuring rotational accuracy: controlling the axial and radial runout of rotating parts to maintain the operating accuracy of the equipment.
[0003] The load-bearing capacity of a bearing directly affects the service life of the equipment. Insufficient load-bearing capacity can lead to fatigue of the bearing raceway and rolling elements, and even cause direct failure of the equipment, such as unstable operation or transmission failure. Therefore, existing technologies typically require testing the load-bearing capacity of bearings. The current testing device involves directly mounting the bearing onto a support bracket and applying pressure to the bearing surface using an electric push rod. When the bearing deforms, a displacement sensor detects the deformation to test the bearing's load-bearing capacity.
[0004] However, existing testing equipment can only statically test a section of the arc surface on the bearing. When all arc surfaces need to be tested, the arc surfaces of the bearing and the pressure sensor need to be adjusted multiple times, resulting in poor testing results and cumbersome testing. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a bearing load capacity testing device to solve the technical problems of poor testing effect and cumbersome testing in the existing static bearing testing method in the background art.
[0006] The present invention provides a bearing load capacity testing device, including a bearing support, a sleeve mechanism, multiple electric push rods and multiple displacement sensors;
[0007] The sleeve mechanism is mounted on the bearing bracket and is used to support the bearing. Multiple electric push rods are circumferentially distributed around the sleeve mechanism with the center of the sleeve mechanism as the origin, so that the output end of each electric push rod is respectively facing different outer arc surfaces of the bearing.
[0008] The detection end of each displacement sensor is positioned opposite to the output end of each electric push rod, and the detection end of each displacement sensor is used to extend into the inner side of the bearing to test different inner arc surfaces of the bearing.
[0009] Furthermore, the testing device also includes a housing with a transparent cover, the sleeve mechanism being disposed within the housing, and the output end of each of the electric push rods being used to pass through the housing.
[0010] Furthermore, the socketing mechanism includes a support shaft and two socketing shafts with limiting bosses;
[0011] The support shaft is connected to the bearing bracket, and both sleeve shafts are used to be sleeved on the support shaft so that when the two sleeve shafts are connected to each other, a gap is formed between the two limiting bosses to restrict the movement of the bearing.
[0012] Furthermore, the socketing mechanism includes a first socket shaft with a first limiting boss and a second socket shaft with a second limiting boss;
[0013] The first sleeve shaft and the second sleeve shaft are detachably connected to each other.
[0014] Furthermore, the first socket shaft and the second socket shaft are threadedly connected.
[0015] Furthermore, all of the displacement sensors are located on the outside of the second sleeve shaft.
[0016] Furthermore, one end of the transparent cover is rotatably connected to the end of the housing.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In the bearing load-bearing capacity testing device of this utility model, multiple electric push rods and multiple displacement sensors are distributed at intervals around the sleeve mechanism. This allows multiple electric push rods to simultaneously apply pressure to multiple outer arc surfaces of the bearing when testing their load-bearing capacity. When one or more outer arc surfaces deform, the corresponding displacement sensor can measure the deformation of the corresponding outer arc surface. This enables simultaneous testing of different outer arc surfaces at once. Furthermore, to ensure that each segment of the bearing's outer arc surface can be tested, the operator can rotate the bearing to switch the bearing and the corresponding outer arc surface of the electric push rod and displacement sensor to other outer arc surfaces. Each switch allows simultaneous testing of multiple different outer arc surfaces, thereby saving the number of operations, greatly improving the testing effect, and reducing operational complexity.

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] Please see Figures 1 to 3 The image shows a bearing load capacity testing device in one embodiment of the present invention. The testing device includes a bearing support 100, a sleeve mechanism 200, multiple electric push rods 300 and multiple displacement sensors 400.
[0027] The sleeve mechanism 200 is mounted on the support bracket 100 and is used to support the bearing 600. Multiple electric push rods 300 are circumferentially distributed around the sleeve mechanism 200 with the center of the sleeve mechanism 200 as the origin, so that the output end of each electric push rod 300 is respectively facing different outer arc surfaces of the bearing 600.
[0028] In this configuration, the detection end of each displacement sensor 400 is positioned opposite to the output end of each electric push rod 300, and the detection end of each displacement sensor 400 is used to extend into the inner side of the bearing 600 to test different inner arc surfaces of the bearing 600.
[0029] In practical implementation, by distributing multiple electric push rods 300 and multiple displacement sensors 400 at intervals around the sleeve mechanism 200, when testing the load-bearing capacity of multiple outer arc surfaces of the bearing 600, multiple electric push rods 300 can simultaneously apply pressure to multiple outer arc surfaces of the bearing 600. When one or more outer arc surfaces deform, the corresponding displacement sensor 400 can test the deformation of the corresponding outer arc surface, enabling simultaneous testing of different outer arc surfaces at one time. Furthermore, to ensure that each segment of the outer arc surface of the bearing 600 can be tested, the operator can rotate the bearing 600, allowing the outer arc surface corresponding to the bearing 600, electric push rods 300, and displacement sensors 400 to be switched to other outer arc surfaces. Each switch allows simultaneous testing of multiple different outer arc surfaces, thereby saving the number of operations, greatly improving the testing effect, and reducing operational complexity.
[0030] For a further understanding of this case, please refer to Figure 3 As shown, the solid line shading drawn on the outer ring of bearing 600 has two segments, which are the two parts that need to be tested. That is to say, every time bearing 600 is manually rotated, there is an untested outer arc surface facing the electric push rod 300 and displacement sensor 400.
[0031] In addition, to fix the bearing 600 on the sleeve mechanism 200, in this embodiment, the sleeve mechanism 200 includes a support shaft 210 and two sleeve shafts with limiting bosses. The support shaft 210 is connected to the bearing bracket 100. Both sleeve shafts are used to be sleeved on the support shaft 210 so that when the two sleeve shafts are connected to each other, a gap is formed between the two limiting bosses to restrict the movement of the bearing 600. Specifically, the sleeve mechanism 200 includes a first sleeve shaft 230 with a first limiting boss 220 and a second sleeve shaft 250 with a second limiting boss 240. The first sleeve shaft 230 and the second sleeve shaft 250 are detachably connected to each other. In some preferred embodiments, the first sleeve shaft 230 and the second sleeve shaft 250 are threadedly connected.
[0032] In practice, the bearing 600 is first fitted onto the first connecting shaft 230. Then, the threaded connection between the first connecting shaft 230 and the second connecting shaft 250 allows the second connecting shaft 250 to be rotatably inserted into the inner ring of the bearing 600. When the second connecting shaft 250 and the first connecting shaft 230 are threadedly connected, the first limiting boss 220 and the second limiting boss 240 can clamp the two sides of the bearing 600, thus preventing the bearing 600 from shifting during load-bearing capacity testing and effectively ensuring the integrity of the test.
[0033] In some other preferred embodiments, multiple displacement sensors 400 are located on the outside of the second sleeve shaft 250. That is, when the second sleeve shaft 250 is installed, the detection end of the displacement sensor 400 is exactly in contact with the inner arc surface of the bearing 600.
[0034] Because the bearing 600 is prone to cracking due to insufficient load-bearing capacity during testing, in order to avoid injury to operators from the resulting fragments, in this embodiment, the testing device also includes a housing 500 with a transparent cover 510. A sleeve mechanism 200 is used to be installed inside the housing 500, and the output end of each electric push rod 300 is used to pass through the housing 500. One end of the transparent cover 510 is rotatably connected to the end of the housing 500. By utilizing the interaction between the transparent cover 510 and the housing 500, the operator can observe the bearing 600's testing status in real time and effectively avoid injury to the operator from the fragments.
[0035] In summary, the bearing load capacity testing device of this utility model has at least the following advantages compared with existing bearing load capacity testing devices:
[0036] In the bearing load-bearing capacity testing device of this utility model, by distributing multiple electric push rods 300 and multiple displacement sensors 400 at intervals around the sleeve mechanism 200, when testing the load-bearing capacity of multiple outer arc surfaces of the bearing 600, multiple electric push rods 300 can simultaneously apply pressure to multiple outer arc surfaces of the bearing 600. When one or more outer arc surfaces deform, the corresponding displacement sensor 400 can test the deformation of the corresponding outer arc surface, enabling simultaneous testing of different outer arc surfaces at one time. Furthermore, in order to ensure that each segment of the outer arc surface of the bearing 600 can be tested, the operator can rotate the bearing 600 to switch the outer arc surface of the bearing 600 corresponding to the electric push rods 300 and displacement sensors 400 to other outer arc surfaces. Each switch allows simultaneous testing of multiple different outer arc surfaces, thereby saving the number of operations, greatly improving the testing effect and reducing the complexity of operation.
