[0002] The track roller is an important mechanical component, whose main function is to support the weight of the tractor and roll on the guide rail or track plate of the track. In addition, the track roller helps to limit the track and prevent it from slipping laterally. When the tractor turns, the track roller can force the track to slide on the ground. The working environment of the track roller is usually harsh. It often works in mud, water and dust and withstands strong impact. Therefore, high requirements are placed on its performance. Therefore, the track roller needs to undergo a series of tests to judge its performance, including torque testing, which requires a torque testing device for track rollers to be used in conjunction.

Before testing the supporting rollers, if the surface is stained with water or dust, it will affect the test and also contaminate the testing equipment. For such high-precision equipment, the protection measures are relatively strict and such pollution needs to be eliminated. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a torque testing device for a track wheel, comprising:

[0024] A bottom plate 1, a fixing assembly, the fixing assembly includes a groove 2 arranged on the upper surface of the bottom plate 1, the inner wall of the groove 2 is rotatably connected with a bidirectional threaded rod 3 through a bearing, and nuts 4 are threadedly connected on the threaded sections of the bidirectional threaded rod 3 with opposite thread directions, the inner wall of the groove 2 is fixedly connected with two guide rods 5, the side walls of the two nuts 4 are connected with two guide plates 6, and the four guide plates 6 are respectively slidably sleeved on the two guide rods 5 in pairs, and the upper surfaces of the two nuts 4 are fixedly connected with support columns 7, and the side walls of the two support columns 7 that are close to one side are fixedly connected with an arc-shaped clamping plate 8, the two arc-shaped clamping plates 8 cooperate with each other, and the arc-shaped inner walls of the two arc-shaped clamping plates 8 correspond to each other. When the fixing assembly is running, the arc-shaped inner walls of the two arc-shaped clamping plates 8 are constantly approaching each other, thereby realizing the clamping and fixing of the supporting roller;

[0025] The cleaning assembly is arranged on the side of the bottom plate 1. The cleaning assembly includes a mounting plate 9 fixedly connected to the upper surface of the bottom plate 1. A first rotating shaft 10 is fixedly connected to one end of the bidirectional threaded rod 3 near the mounting plate 9. The first rotating shaft 10 penetrates and is rotatably connected to the side wall of the bottom plate 1. A second rotating shaft 11 is arranged above the bottom plate 1. The second rotating shaft 11 penetrates and is rotatably connected to the side wall of the mounting plate 9 through a bearing. A driving wheel 12 is fixedly connected to the circumference of the first rotating shaft 10, and a driven wheel 13 is fixedly connected to the circumference of the second rotating shaft 11. A belt 14 is wound between the wheel 12 and the driven wheel 13, a blowing fan blade 15 is fixedly connected to the end of the second rotating shaft 11 away from the driven wheel 13, and a knob is fixedly connected to the end of the two-way threaded rod 3 away from the mounting plate 9, which is convenient for the staff to operate. A plurality of ventilation holes 16 are provided on the side wall of the mounting plate 9, and the plurality of ventilation holes 16 are all arranged around the second rotating shaft 11, so that the cleaning component can work normally. There is a large transmission ratio between the driving wheel 12 and the driven wheel 13, so that the blowing fan blade 15 can generate stronger wind force.

[0026] The detailed working process of the utility model is as follows:

[0027] When in use, when it is necessary to fix the track roller, place the track roller between the two arc-shaped clamping plates 8, and then turn the two-way threaded rod 3 by means of a knob. When the two-way threaded rod 3 rotates, the two nuts 4 will not rotate along with it under the influence of the guide plate 6 and the guide rod 5, but the two-way threaded rod 3 will be threadedly engaged, and then the two nuts 4 will move toward each other along the two-way threaded rod 3. When it is necessary to fix the track roller, the two nuts 4 will approach each other, and then drive the two support columns 7 and the arc-shaped clamping plates 8 to approach each other, so as to achieve clamping and fixing of the track roller. After completing the stable fixing of the track roller, the track roller is tested by a torque testing instrument to achieve stable clamping, so as to ensure the accuracy of subsequent tests.

[0028] When the supporting roller is clamped and fixed, the bidirectional threaded rod 3 rotates, thereby driving the No. 1 rotating shaft 10 to rotate. When the No. 1 rotating shaft 10 rotates, the driving wheel 12 is driven to rotate, and then the driven wheel 13 and the No. 2 rotating shaft 11 are driven to rotate through the transmission of the belt 14. The rotation of the No. 2 rotating shaft 11 will drive the blowing fan blades 15 to rotate. The blowing fan blades 15 generate airflow to deal with dust or water stains on the surface of the supporting roller to prevent these impurities from affecting the test or contaminating the test equipment.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
