[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling the reader to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0036] Example 1

[0037] like Figure 1-7As shown, a bearing seat test platform includes a test bench 1 and a test mechanism 2. The test bench 1 is horizontally arranged; the test mechanism 2 includes a base 21, a motor 22, and a bearing 24 and a rotating shaft 25 arranged in a bearing seat 23 to be tested; the bearing seat 23 to be tested includes a support 231 and a bearing sleeve 232; the support 231 is vertically arranged on the rear side of the top surface of the test bench 1, and the bearing sleeve 232 is horizontally fixed on the support 231; the bearing 24 is assembled on the bearing sleeve 232 of the bearing seat 23 to be tested 32, and two are arranged at intervals on the left and right; the rotating shaft 25 is horizontally assembled in the two bearings 24, and its two ends extend outward from the outside of the bearing seat 23 to be tested; the bearing sleeve 232 of the bearing seat 23 to be tested is provided with detection holes 2321 on the side walls corresponding to the two bearings 24; the detection holes 2321 are connected to the temperature sensor (not shown in the figure); the base 21 is arranged on the test bench 1, located in front of the bearing seat 23 to be tested; the motor 22 is arranged on the base 21, and its output shaft drives the rotating shaft 25 to rotate. The motor 22 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the two bearings 24 to rotate in the bearing seat 23 to be tested. The temperature probe of the temperature sensor passes through the detection hole 2321 on the bearing seat 23 to be tested, and at the same time, the damage of the bearing 24 is checked, so that the performance of the bearing seat 23 to be tested can be tested and evaluated.

[0038] Furthermore, the bearing 24 is a spherical roller bearing, which can rotate within a certain angle, thereby avoiding the heat generated by accidental friction due to incorrect assembly angle, causing abnormal temperature rise, increased butter consumption, and reducing the service life of the bearing 24, thereby ensuring the accuracy of the test under external conditions.

[0039] like Figure 2 As shown, in the further, the two bearings 24 are assembled in the measured bearing seat 23 in such a way that one of them is fastened and the other is loose. The fastened assembled bearing 24 can ensure that the rotating shaft 25 can be normally stuck inside the measured bearing seat 23 and is not easy to slip out of place. The free assembled bearing 24 can make the rotating shaft 25 self-adjust during the rotation process, reduce the heat generated by friction, and further ensure the test accuracy.

[0040] like Figure 1 , 5 As shown, there are two test mechanisms 2, which are arranged on the test bench 1 at intervals. In the two test mechanisms 2, the output shafts of the motors 22 face each other. The two test mechanisms 2 can perform synchronous tests on the two tested bearing seats 23, thereby improving the test efficiency.

[0041] like Figure 1As shown, the output shaft of the motor 22 and the rotating shaft 25 are fixedly sleeved with a pulley 26 on one end in the same direction as the output shaft of the motor 22 ; the pulley 26 is connected through a transmission belt 27 .

[0042] like Figure 1 , 4 As shown, the test bench 1 also includes a belt pressing mechanism 3, which includes a bottom plate 31, a mounting plate 32, a rotating rod 33, and a belt pressing roller 34; the mounting plate 32 is arranged on the top surface of the test bench 1 and is located below the middle of the transmission belt 27; the mounting plate 32 is vertically arranged on the top surface of the bottom plate 31, and two mounting plates 32 are arranged at intervals on the left and right sides, and the two mounting plates 32 are located on the left and right sides of the transmission belt 27, and the side walls of the mounting plates 32 are provided with a card slot; the rotating rod 33 is arranged horizontally on the left and right sides, and its left and right sides are arranged in the card slot of the mounting plate 32, and the two ends extend outward; the belt pressing roller 34 is arranged horizontally on the left and right sides, and is rotatably sleeved on the rotating rod 33 through the belt pressing roller bearing, and the belt pressing roller 34 is located between the upper and lower sides of the transmission belt 27, and its bottom surface contacts the top surface of the lower side of the transmission belt 27. The belt pressing roller 34 can adjust the tension of the transmission belt 27, so that the transmission mechanism runs more smoothly and ensures the accuracy of the test.

[0043] like Figure 5 As shown, the pulley 26 is a V-belt pulley 26.1; the transmission belt 27 is a V-belt 27.1; the V-belt pulley 26.1 is connected by the V-belt 27.1. The output shaft of the motor 22 rotates, driving the V-belt pulley 26.1 on its output shaft to rotate, and the V-belt pulley 26.1 on the rotating shaft 25 rotates through the V-belt 27.1, so that the rotating shaft 25 rotates, and the rotating shaft 25 drives the bearing 24 to rotate in the bearing seat 23 to be tested. The temperature of the bearing 24 is detected by the temperature sensor, and the damage of the bearing 24 is checked at the same time, so that the performance of the bearing seat 23 to be tested under the transmission mode of the V-belt 27.1 can be tested and evaluated.

[0044] like Figure 4 As shown, the belt pressing mechanism 3 further includes an adjusting block 35, a connecting block 36, and an adjusting screw 37; the adjusting blocks 35 are respectively arranged at the left and right ends of the rotating rod 33 and are fixedly connected to the rotating rod 33; the connecting block 36 is horizontally arranged on the opposite side of the two mounting plates 32, and a threaded hole is provided on its top surface; the adjusting screw 37 is vertically arranged on the threaded hole of the connecting block 36, and its top surface is in contact with the connecting block 36. By raising and lowering the adjusting screw 37 on the threaded hole, the adjusting block 36 is raised and lowered, and the adjusting block 35 is driven to rise and fall, thereby adjusting the height of the belt pressing wheel 34, which can flexibly adjust the tension of the transmission belt 27 and adapt to different transmission belts 27.

[0045] like Figure 6As shown, the rear side of the top surface of the test bench 1 is provided with a straight slot 11 which is opened along the front and back and passes through the top and bottom; the straight slots 11 are arranged in pairs, and there are two groups in total, and the two groups of straight slots 11 are arranged at intervals from left to right, and the straight slots 11 between each group are arranged at intervals from left to right; the support 231 of the measured bearing seat 23 is provided with connecting holes 2311 on the left and right sides, and the connecting holes 2311 and the straight slots 11 are connected by bolts. When it is necessary to adjust the position of the measured bearing seat 23, the nut of the bolt can be loosened so that the measured bearing seat 23 can move in the straight slot 11; when it is necessary to fix the measured bearing seat 23, the nut of the bolt can be tightened, which can facilitate the position adjustment and fixation of the measured bearing seat 23 in the horizontal direction, thereby adjusting the distance between the measured bearing seat 23 and the motor 22, adapting to the installation of different transmission belts 27, improving the scope of application, and facilitating operation.

[0046] like Figure 7 As shown, all edges of the bottom of the support 231 of the bearing seat 23 to be tested are provided with a plurality of vertically arranged guard plates 28; each group of the straight slots 11 is provided with a fixed pressure plate 12 on both sides; the fixed pressure plate 12 is an L-shaped plate structure arranged horizontally in the front and rear, and its horizontal side is connected to the top surface of the test bench 1, and the vertical side is close to the straight slot 11, and a plurality of left and right through screw holes 121 are arranged at intervals in the front and rear on the vertical side of the fixed pressure plate 12; the screw holes 121 are provided with clamping bolts 13 horizontally in the left and right. After the bearing seat 23 to be tested is fixed in the straight slot 11, the clamping bolts 13 are tightened to press the clamping bolts 13 on the guard plates 28, thereby further fixing the bearing seat 23 to be tested, so that the bearing seat 23 to be tested remains stable during the test.

[0047] like Figure 1 As shown, a protective cover is also included; the protective cover is arranged on the pulley 26 and the transmission belt 27, and its bottom surface is connected to the top surface of the test bench 1. The protective cover is used to protect the transmission mechanism to prevent safety accidents during the test process.

[0048] Example 2

[0049] like Figure 8 As shown, it is basically the same as the embodiment 1, except that the pulley 26 is a synchronous pulley 26.2; the transmission belt 27 is a synchronous belt 27.2; and the synchronous pulley 26.2 is connected by the synchronous belt 27.2. The output shaft of the motor 22 rotates, driving the synchronous pulley 26.2 on its output shaft to rotate, and the synchronous pulley 26.2 on the rotating shaft 25 rotates through the synchronous belt 27.2, so that the rotating shaft 25 rotates, and the rotating shaft 25 drives the bearing 24 to rotate in the measured bearing seat 23. The temperature of the bearing 24 is detected by the temperature sensor, and the damage of the bearing 24 is checked at the same time, so that the performance of the measured bearing seat 23 under the transmission mode of the synchronous belt 27.2 can be tested and evaluated.

[0050] Example 3

[0051] like Fig. 9 As shown, it is basically the same as Example 1, except that in one of the test mechanisms 2, the pulley 26 provided on the output shaft of the motor 22 and the rotating shaft 25 is a V-belt pulley 26.1, and the transmission belt 27 is a V-belt 27.1; in the other test mechanism 2, the pulley 26 provided on the output shaft of the motor 22 and the rotating shaft 25 is a synchronous pulley 26.2, and the transmission belt 27 is a synchronous belt 27.2. The motors 22 in the two test mechanisms 2 drive the rotating shaft 25 to rotate through the V-belt 27.1, the V-belt pulley 26.1, and the synchronous belt 27.2, the synchronous pulley 26.2, respectively, so as to test and evaluate the performance of the tested bearing seat 23 under different transmission modes.

[0052] Example 4

[0053] The testing method of the present invention is as follows: start the motor 22 and run it continuously for 8 hours at full speed; within the first hour, measure the temperature of the bearing 24 once every 10 minutes through the temperature sensor, record the temperature, and check whether the bearing 24 is damaged; within the 2nd to 4th hours, measure the temperature of the bearing 24 once every hour through the temperature sensor, record the temperature, and check whether the bearing 24 is damaged; at the end of the 8th hour, measure the temperature once, record the temperature, and check whether the bearing 24 is damaged.

[0054] If the temperature fluctuation of the bearing 24 is too large, or the bearing 24 is damaged, it means that the assembly performance of the bearing 24 in the bearing seat 23 under test is insufficient.

[0055] Example 5

[0056] Since the belt pressing mechanism 3 is required to be used in different transmission modes, the present invention can also be used to test the performance of the belt pressing wheel 34 of the belt pressing mechanism 3 .

[0057] The performance test method of the belt-pressing roller 34 is basically the same as that of the fourth embodiment, except that the temperature and damage of the belt-pressing roller 34 and the belt-pressing roller bearing are tested. Fig.10 As shown, A is the temperature measuring point of the pressure roller, and B is the temperature measuring point of the pressure roller bearing. If the temperature fluctuation of the pressure roller 34 and the pressure roller bearing is too large, or the pressure roller 34 and the pressure roller bearing are damaged, it means that the performance of the pressure roller 34 and the pressure roller bearing is insufficient.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
