Description

Technical Field

[0001] The utility model relates to the technical field of machinery, and particularly relates to a wear test device for a wheel-shaped body. Background Art

[0002] In order to test the wear resistance of a wheel-shaped material under actual working conditions, and for factory inspection or testing of a wheel-shaped body, a wear test device for a wheel-shaped body is required. A relatively close existing technology is a belt wear resistance test mechanism disclosed in CN107796721A. By driving a driving wheel and a driven wheel with a motor, parameters such as the wear resistance and service life of the belt are tested, and the tension of the belt is adjusted by selecting driving wheels and driven wheels with different diameters. However, if this mechanism is directly applied to the test of a wheel-shaped body, the wheel-shaped body needs to be continuously tested. During the test, the diameter of the wheel-shaped body will become smaller and smaller due to wear, resulting in a decrease in the test tension, thereby affecting the test effect. Summary of the Invention

[0003] The utility model aims to overcome the deficiencies of the prior art and provides a wear test device for a wheel-shaped body.

[0004] To achieve the above object, a wear test device for a wheel-shaped body is designed, which includes a driving test wheel and a driven test wheel. The driving test wheel and the driven test wheel are driven by a transmission belt, the driving test wheel is connected to a rotation driving device, the driven test wheel is provided with a braking device, and at least one of the driving test wheel and the driven test wheel is installed on a movable bracket, and one side of the bracket is connected to a linear driving device.

[0005] The driven test wheel is installed on a movable bracket, and a guide rail slider mechanism is provided below the bracket and the braking device.

[0006] The rotation driving device is a hydraulic motor.

[0007] The braking device is an eddy current brake. The driven test wheel is connected to the eddy current brake through a coupling, and the eddy current brake is electrically connected to a current controller.

[0008] A water tank is provided below the driving test wheel and the driven test wheel, and a cover plate is provided above the driving test wheel and the driven test wheel.

[0009] The transmission belt is a diamond wire rope.

[0010] The linear driving device is a cylinder.

[0011] Compared with the prior art, in the present utility model, the test wheel is installed on a movable bracket, and the position of the bracket is adjusted by a linear driving device. After the test wheel wears, the position of the test wheel can be adjusted to maintain the tension between the measured wheel and the transmission belt, so that the wear test can continue and the test effect can be ensured.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further described below with reference to the accompanying drawings.

[0016] As Figure 1 shown, the active test wheel 1 and the passive test wheel 2 are driven by the transmission belt 3. The active test wheel 1 is connected to the rotary drive device 4, and the passive test wheel 2 is provided with a braking device 5. At least one of the active test wheel 1 and the passive test wheel 2 is installed on the movable bracket 6, and one side of the bracket 6 is connected to the linear drive device 7. Both the active test wheel 1 and the passive test wheel 2 can be the wheel-shaped bodies to be tested. The wheel-shaped bodies are driven by the transmission belt 3. The active test wheel 1 is driven to rotate by the rotary drive device 4, and drives the passive test wheel 2 to rotate through the transmission belt 3. The braking device 5 generates a braking force on the passive test wheel 2, so that the passive test wheel 2 generates a load. The linear drive device 7 drives the bracket 6 to move, which can compensate for the maximum distance reduction caused by wear between the active test wheel 1 and the passive test wheel 2, and keep the transmission belt 3 taut.

[0017] The passive test wheel 2 is installed on the movable bracket 6, and a guide rail slider mechanism 8 is provided below the bracket 6 and the braking device 5. The passive test wheel 2 is installed on the movable bracket 6, and the braking device 5 is also installed on the guide rail slider mechanism 8. When the bracket 6 moves, the braking device 5 moves together with the bracket 6.

[0018] The rotary drive device 4 is a hydraulic motor. The hydraulic motor drive can achieve tests under high speed and high load.

[0019] The braking device 5 is an eddy current brake. The passive test wheel 2 is connected to the eddy current brake through a coupling, and the eddy current brake is electrically connected to a current controller. After the eddy current brake is powered on, a braking force is generated and transmitted to the passive test wheel 2, thereby causing a load on the passive test wheel 2. By adjusting the current magnitude of the eddy current controller through the current controller, the braking force generated by the brake can be adjusted.

[0020] A water tank 9 is provided below the active test wheel 1 and the passive test wheel 2, and a cover plate 10 is provided above the active test wheel 1 and the passive test wheel 2. Filling the water tank 9 with water can simulate the working conditions of the test wheels when they are wet, and the cover plate 10 can prevent water from splashing out or the test wheels and the transmission belt 3 from bursting and flying out.

[0021] The transmission belt 3 is a diamond wire rope. The diamond wire rope has strong wear resistance, which enables the transmission belt 3 to continuously conduct wear tests for a long time.

[0022] The linear drive device 7 is a cylinder. The tension of the tension can be adjusted by adjusting the air pressure of the cylinder, and the magnitude of the tension force can be kept stable within the stroke range of the cylinder.

[0023] When the utility model is in use, the active test wheel 1 is connected to the rotating shaft of the hydraulic motor, the passive test wheel 2 is installed on the bracket 6 and connected to the eddy current brake through a coupling, and a diamond wire rope is sleeved between the active test wheel 1 and the passive test wheel 2 as the transmission belt 3. Start the cylinder to tension the transmission belt 3, and then turn on the eddy current brake and the hydraulic motor to start the wear test. After the test wheels are worn, the cylinder drives the bracket 6 to move outward along the guide rail slider mechanism 8 to compensate for the worn distance, and the tension force can be kept constant. After running for a certain period of time, remove the active test wheel 1 and the passive test wheel 2, and measure the actual wear with a caliper.
