[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0036] Example 1

[0037] like Figures 1-7 As shown, a bearing housing testing platform includes a test bench 1 and a testing mechanism 2. The test bench 1 is horizontally positioned. The testing mechanism 2 includes a base 21, a motor 22, and a bearing 24 and a rotating shaft 25 disposed within a bearing housing 23 to be tested. The bearing housing 23 to be tested includes a support 231 and a bearing sleeve 232. The support 231 is vertically positioned on the rear side of the top surface of the test bench 1, and the bearing sleeve 232 is horizontally fixed to the support 231. The bearing 24 is assembled into the bearing sleeve 232 of the bearing housing 23 to be tested. Within the test bench 1, two bearings 24 are spaced apart on the left and right. The rotating shaft 25 is horizontally mounted inside the two bearings 24, with its two ends extending outwards from the bearing housing 23 under test. The bearing sleeve 232 of the bearing housing 23 under test has detection holes 2321 on the side walls corresponding to the two bearings 24. The detection holes 2321 are connected to a temperature sensor (not shown in the figure). The base 21 is set on the test bench 1, located in front of the bearing housing 23 under test. The motor 22 is set 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 housing 23 under test. The temperature probe of the temperature sensor detects the temperature of the bearings 24 through the detection holes 2321 on the bearing housing 23 under test, and at the same time checks the damage of the bearings 24, thus testing and evaluating the performance of the bearing housing 23 under test.

[0038] Furthermore, the bearing 24 is a self-aligning roller bearing. Self-aligning roller bearings can rotate within a certain angle, avoiding problems such as abnormal temperature rise caused by heat generated by accidental friction due to incorrect assembly angle, increased grease consumption, and reduced service life of bearing 24, thus ensuring the accuracy of external conditions for testing.

[0042] like Figure 1 , 4 As shown, the system also includes a belt pressing mechanism 3, which comprises a base plate 31, a mounting plate 32, a rotating rod 33, and a belt pressing wheel 34. The mounting plate 32 is located on the top surface of the test bench 1 and below the middle of the transmission belt 27. The mounting plate 32 is vertically arranged on the top surface of the base plate 31, with two plates spaced apart on the left and right sides of the transmission belt 27. The side walls of the mounting plate 32 have slots. The rotating rod 33 is horizontally arranged on the left and right sides, with its left and right sides located in the slots of the mounting plate 32 and its ends extending outwards. The belt pressing wheel 34 is horizontally arranged on the left and right sides and is rotatably mounted on the rotating rod 33 via a belt pressing wheel bearing. The belt pressing wheel 34 is located between the upper and lower edges of the transmission belt 27, with its bottom surface in contact with the top surface of the lower edge of the transmission belt 27. The belt pressing wheel 34 can adjust the tension of the transmission belt 27, making the transmission mechanism run more smoothly and ensuring the accuracy of the test.

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

[0044] As shown in Figure 4 The pressing belt mechanism 3 further comprises an adjusting block 35, a connecting block 36 and an adjusting screw 37. The adjusting block 35 is arranged at the left and right ends of the rotating rod 33 and is fixedly connected with the rotating rod 33. The connecting block 36 is horizontally arranged on the side opposite to the two mounting plates 32, and the top surface of the connecting block 36 is provided with a threaded hole penetrating therethrough. The adjusting screw 37 is vertically arranged on the threaded hole of the connecting block 36, and the top surface of the adjusting screw 37 is in contact with the connecting block 36. The height of the pressing belt wheel 34 is adjusted by lifting the adjusting block 36 through the lifting of the adjusting screw 37 in the threaded hole, so as to drive the adjusting block 35 to lift, thereby adjusting the height of the pressing belt wheel 34, and the tension of the transmission belt 27 can be flexibly adjusted, and different transmission belts 27 can be adapted.

[0045] As shown in Figure 6 The top surface of the test bench 1 is provided with straight grooves 11 which are arranged in front and back and penetrate upward and downward. The straight grooves 11 are arranged in pairs and are divided into two groups. The straight grooves 11 in each group are arranged in pairs and are spaced apart. 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 grooves 11 are connected by bolts. When the position of the measured bearing seat 23 needs to be adjusted, the nut of the bolt is loosened, so that the measured bearing seat 23 can move in the straight groove 11. When the measured bearing seat 23 needs to be fixed, the nut of the bolt is tightened, so that the position of the measured bearing seat 23 in the horizontal direction can be adjusted and fixed, 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 application range, and facilitating operation.

[0046] As shown in Figure 7As shown, the bottom of the bearing seat 23 is provided with a plurality of vertical guards 28; each group of straight slots 11 is provided with a fixed pressing plate 12; the fixed pressing plate 12 is an L-shaped plate structure arranged horizontally, and the horizontal edge is connected with the top surface of the test table 1, and the vertical edge is close to the straight slot 11, and a plurality of left-right through screw holes 121 are arranged on the vertical edge of the fixed pressing plate 12; the screw hole 121 is provided with a pressing bolt 13 arranged horizontally. After the bearing seat 23 is fixed in the straight slot 11, the pressing bolt 13 is tightened on the guard 28, so that the bearing seat 23 is further fixed, and the bearing seat 23 is kept stable during the test.

[0047] As shown in Figure 1 It also includes a protective cover; the protective cover is arranged on the pulley 26 and the transmission belt 27, and the bottom surface is connected with the top surface of the test table 1. The protective cover is used to protect the transmission mechanism and prevent safety accidents during the test.

[0048] Example 2

[0049] As shown in Figure 8 It is basically the same as example 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 the output shaft to rotate, and through the synchronous belt 27.2, the synchronous pulley 26.2 on the rotating shaft 25 is driven to rotate, so that the rotating shaft 25 rotates, and the bearing 24 in the bearing seat 23 is driven to rotate by the rotating shaft 25. The temperature of the bearing 24 is detected by the temperature sensor, and the damage of the bearing 24 is checked, so that the performance of the bearing seat 23 under the synchronous belt 27.2 transmission mode can be tested and evaluated.

[0050] Example 3

[0051] As shown in Figure 9 It is basically the same as example 1, except that in one of the test mechanisms 2, the pulley 26 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 another test mechanism 2, the pulley 26 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 motor 22 in the two test mechanisms 2 drives the rotating shaft 25 to rotate through the V-belt 27.1, the V-belt pulley 26.1, the synchronous belt 27.2, and the synchronous pulley 26.2, so that the performance of the bearing seat 23 under different transmission modes can be tested and evaluated.

[0052] Example 4

[0053] The test method of the utility model is: starting motor 22, under the condition of full speed, total continuous operation 8 hours; within the first hour, every 10 minutes, bearing 24 is measured temperature once through temperature sensor, and records temperature, and checks whether bearing 24 is damaged; within the 2-4 hours, every 1 hour, bearing 24 is measured temperature once through temperature sensor, records temperature, and checks whether bearing 24 is damaged; at the end of the 8 hours, measures temperature once, records temperature, and checks whether bearing 24 is damaged.

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

[0055] Example 5

[0056] Since the supporting pressure belt mechanism 3 needs to be used under different transmission modes, the utility model can also be used to test the performance of the pressure belt mechanism 3.

[0057] The performance test method of the pressure belt wheel 34 is basically the same as that of example 4, but the only difference is that the temperature and damage of the pressure belt wheel 34 and the pressure belt wheel bearing are detected. The detection point is as shown in the figure, A is the pressure belt wheel temperature measuring point, B is the pressure belt wheel bearing temperature measuring point. If the temperature fluctuation of the pressure belt wheel 34 and the pressure belt wheel bearing is too large, or the pressure belt wheel 34 and the pressure belt wheel bearing are damaged, it indicates that the performance of the pressure belt wheel 34 and the pressure belt wheel bearing is insufficient. Figure 10

[0058] The above is only the preferred embodiment of the utility model, it should be pointed out that, for ordinary skilled person in the art, without departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the utility model.​
