Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, specifically a military bearing test torque testing platform. Background Technology

[0002] Angular contact bearings are bearings in which the line connecting the contact points of the rollers and inner and outer rings forms a certain angle with the radial direction of the bearing. They can simultaneously withstand radial loads and single axial loads. The working environment of angular contact ball bearings usually requires bearing combined radial and axial loads, and the axial load is usually relatively large. Therefore, the frictional torque under axial load is one of the important parameters reflecting the performance of angular contact bearings. For this reason, it is often necessary to conduct tests on the frictional torque to verify whether the bearing design and manufacturing process are reasonable, and to provide a basis for further improving the bearing quality.

[0003] A search revealed Chinese patent application CN 215573766 U, which discloses a precision angular contact bearing friction torque testing machine. The machine includes a drive unit, a loading unit, and an auxiliary unit. The drive unit includes a rotating main shaft with a test station for mounting a single test bearing. The auxiliary unit includes an auxiliary shaft and a test bearing. The loading unit is driven by the auxiliary shaft. The test bearing is mounted on the auxiliary shaft and is symmetrically positioned to reflect the test bearing. The auxiliary shaft is flexibly connected to the main shaft and rotates synchronously. Addressing the shortcomings of existing technologies, this invention provides a precision angular contact bearing friction torque testing machine capable of testing single angular contact bearings, facilitating data collection, and ensuring data accuracy.

[0004] However, when testing military bearings, most testing machines require placing the bearings on the output shaft of the motor and then inside the sensor for testing. This is inconvenient because the number of bearings is large. Therefore, we propose a torque testing platform for military bearings. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-4 This utility model provides a military bearing testing torque testing platform, including a base 1. A motor 2 and a sensor 3 are fixedly connected to the upper surface of the base 1. A load device 4 is fixedly connected to the upper surface of the base 1. The output shaft of the motor 2 has a groove 5. A movable mechanism 6 is provided on the inner surface of the groove 5. The movable mechanism 6 includes a rotating rod 61. A transmission shaft 62 is fixedly connected to the lower surface of the rotating rod 61. Through the cooperation between the groove 5 and the rotating rod 61, the rotating rod 61 can drive the transmission shaft 62 to rotate 180 degrees, facilitating the placement of the bearing inside the transmission shaft 62. A limit switch is fixedly connected to the lower surface of the transmission shaft 62. The rod 63 has a groove 64 on its front surface. A conical block 65 is slidably connected to the inner surface of the groove 64. The groove 64 limits the conical block 65, making it more stable when sliding. There are two sets of conical blocks 65. The two sets of conical blocks 65 are fixedly connected to the two ends of the spring 66. The output shaft of the load device 4 has a groove 67. A conical groove 68 is formed on the inner surface of the groove 67. The conical groove 68 is slidably connected to the conical block 65. Through the conical groove 68 in the groove 67, the curved surface of the conical block 65 will contact the inner surface of the groove 67 through the action of the limiting rod 63. After the curved surface is compressed, The conical block 65 retracts into the groove 64 and compresses the spring 66. After the conical block 65 and the conical groove 68 are on the same horizontal plane, the spring force of the spring 66 pushes the conical block 65 into the conical groove 68. The inner surface of the limiting rod 63 has a cross groove 69, and the inner surface of the cross groove 69 is slidably connected to the slider 610. The cross groove 69 makes the slider 610 more stable when sliding. The lower surface of the slider 610 is fixedly connected to the locking rod 611, and the outer arc surface of the conical block 65 has a locking groove. 612, the slot 612 is slidably connected to the lever 611. Through the cooperation of the slot 612 and the lever 611, the slider 610 can limit the cone block 65 when it moves downward, so that the cone block 65 cannot retract. The inner surface of the cross groove 69 is provided with a slide 613. The inner surface of the slide 613 is slidably connected to the lever 611. The slide 613 and the slot 612 are on the same horizontal plane. Through the setting of the slide 613, the lever 611 can move downward and be engaged in the slot 612.

[0026] In this embodiment, by setting up the rotating rod 61, the conical block 65, the conical groove 68, and the limiting rod 63, the rotating rod 61 can drive the transmission shaft 62 to rotate. When it is necessary to place the bearing inside the sensor 3, simply pull the transmission shaft 62 upward, put the bearing on the transmission shaft 62, rotate the transmission shaft 62, and the conical block 65 will lock it into the conical groove 68. The operation is simple, thereby effectively improving the testing efficiency of military bearings.

[0027] Example 2

[0028] Please see Figures 1-4 Based on Embodiment 1, this utility model provides a technical solution: Preferably, a limiting mechanism 7 is provided on the inner surface of the cross groove 69. The limiting mechanism 7 includes a fixing rod 71, the lower surface of which is fixedly connected to the inner surface of the cross groove 69, and a fixing block 72 passing through and slidably connected to the upper surface of the fixing rod 71. A spring 73 is sleeved on the outer arc surface of the fixing rod 71. The left surface of the fixing block 72 is fixedly connected to the right surface of the slider 610. A limiting groove 74 is formed on the inner surface of the cross groove 69. The limiting groove 74 limits the triangular plate 75, allowing the triangular plate 75 to slide stably within the limiting groove 74. The inner surface of the limiting groove 74 is slidably connected to the triangular plate 75. Plate 75 is fixedly connected to one end of spring 3 76, and the inner surface of limiting groove 74 is fixedly connected to the other end of spring 3 76. A triangular groove 77 is provided on the right surface of fixing block 72. Triangular groove 77 is slidably connected to triangular plate 75. Through the mutual cooperation of triangular groove 77 and triangular plate 75, triangular plate 75 can be inserted into triangular groove 77 by the elastic force of spring 3 76. At the same time, after the inclined surface of triangular plate 75 is squeezed by triangular groove 77 and disengaged from triangular groove 77, it can be driven to move slider 610 and fixing block 72 upward by the elastic force of spring 2 73. Before triangular plate 75 returns to its original position by the elastic force of spring 3 76, slider 610 returns to its original position by the elastic force of spring 2 73.

[0029] In this embodiment, by setting up the fixing rod 71, fixing block 72, triangular groove 77 and triangular plate 75, after the slider 610 moves downward and is engaged in the groove 612 by the locking rod 611, the fixing block 72 is limited by the triangular plate 75, ensuring that the whole device is more stable.

[0030] Working principle: When testing military bearings, rotate the rotating rod 61 180 degrees so that the drive shaft 62 faces upwards. Place the bearing on the drive shaft 62, then rotate the rotating rod 61 90 degrees to make the limiting rod 63 engage in the second groove 67. At this time, as the conical block 65 moves through the limiting rod 63, its curved surface is squeezed by the second groove 67, causing the conical block 65 to contract into the slide groove 64 and compress the first spring 66. After becoming parallel to the conical groove 68, the spring force of the first spring 66 propels the conical block 65 into the conical groove 68. After the cone block 65 is placed in the groove 68, the slider 610 is moved to compress the spring 73. At the same time, the slider 610 drives the locking rod 611 to engage in the groove of the locking slot 612, limiting the cone block 65. Meanwhile, the fixing block 72 will squeeze the inclined surface of the triangular plate 75, causing the triangular plate 75 to retract into the limiting groove 74. After it is parallel to the triangular groove 77, it is engaged in the triangular groove 77 by the spring 76, limiting the slider 610. After the above operations are completed, the military bearing is placed in the sensor 3, and the motor 2 is started.
