[0002] The wet brake is a type of brake. In order to test the performance of the brake, a series of test detections need to be carried out on the brake, including the inertia test of the wet brake. During the inertia test, a corresponding inertia test bench is required.
[0003] When the existing wet brake inertia test bench is actually used, the wet brake needs to be fixed on the bearing frame by bolts to position the brake, and then the power shaft of the test assembly is connected to the shaft end of the brake by a coupling for testing. However, when disassembling and assembling the brake, a large number of bolts and nuts need to be disassembled and assembled, which is troublesome to operate, affects the detection efficiency, and at the same time, the high-frequency disassembly and assembly are likely to cause bolt wear. Therefore, we propose a wet brake inertia test bench. Content of the Utility Model

The outer end of the transmission shaft of the servo motor penetrates through and is fixedly connected to one end of a gearbox, and the gearbox is fixed on the top of the tabletop. The output end of the gearbox is fixedly connected with a rotating shaft. The outer end of the rotating shaft is connected with a coupling. The outer wall of the rotating shaft is fixedly sleeved with a torque sensor, and the torque sensor is fixed on the top of the tabletop;
[0006] On the other side of the top of the tabletop, a carrier is installed. The carrier is a right-angle plate. A through hole is opened on the vertical plate of the carrier.

Both sides of one end of the carrier are fixedly provided with support plates. An electric push rod is fixedly provided on the outer wall of the support plate. The push rod of the electric push rod movably penetrates through the support plate and is fixedly connected with a pressing plate.
[0007] By adopting the above technical solution, first place the wet brake on the carrier, align the holes on the flange of the wet brake with the positioning bush, and make the shaft of the wet brake penetrate through the through hole on the carrier. Then start the electric push rod to drive the pressing plate to press against one side wall of the wet brake, so as to position the wet brake. Then use the coupling to connect the shaft on the wet brake and the rotating shaft. Then start the servo motor to drive the rotating shaft to rotate and perform test operations through the speed change of the gearbox. During the test, use the wet brake for braking, and then feedback data to the computer through the torque sensor, so as to realize the inertia experiment. After the test is completed, move the pressing plate back, and then directly remove the wet brake from the positioning column.
[0008] As a preferred embodiment of the present invention, the positioning column is a conical column.
[0009] By adopting the above technical solution, when positioning the holes on the flange of the brake, it can ensure fitting and positioning with the holes, avoid loosening and the existence of gaps, thus ensuring the stability of the wet brake during the detection process, avoiding the situation of the wet brake shaking, and thus ensuring the accuracy of the test detection.

[0027] Please refer to Figures 1-3, the present utility model provides a technical solution: a wet brake inertia test bench, including a tabletop 1. One end of the top of the tabletop 1 is fixedly provided with a support 12. The top of the support 12 is fixedly provided with a servo motor 13. The outer end of the transmission shaft of the servo motor 13 penetrates through and is fixedly connected to one end of a gearbox 14, and the gearbox 14 is fixed on the top of the tabletop 1. The output end of the gearbox 14 is fixedly connected to a rotating shaft 15. The outer end of the rotating shaft 15 is connected with a coupling 18. The outer wall of the rotating shaft 15 is fixedly sleeved with a torque sensor 16, and the torque sensor 16 is fixed on the top of the tabletop 1;
[0028] On the other side of the top of the tabletop 1, a carrier 2 is installed. The carrier 2 is a right-angle plate. A through hole 21 is opened on the vertical plate of the carrier 2. A plurality of evenly distributed positioning columns 22 are annularly installed on one side wall of the vertical plate of the carrier 2. Both sides of one end of the carrier 2 are fixedly provided with support plates 3. An electric push rod 31 is fixedly installed on the outer wall of the support plate 3. The push rod of the electric push rod 31 movably penetrates through the support plate 3 and is fixedly connected to a pressing plate 32;
[0029] During actual use, first place the wet brake on the carrier 2, and align the holes on the flange of the wet brake with the positioning columns 22 and put them on, and make the shaft of the wet brake penetrate through the through hole 21 on the carrier 2. Then start the electric push rod 31 to drive the pressing plate 32 to press against one side wall of the wet brake, so as to realize the positioning of the wet brake. Then use the coupling 18 to connect the shaft on the wet brake and the rotating shaft 15. Then start the servo motor 13 to drive the rotating shaft 15 to rotate and perform test operations after speed change by the gearbox 14. During the test, use the wet brake for braking, and then feedback data to the computer through the torque sensor 16, so as to realize the inertia experiment. After the test is completed, move the pressing plate 32 back, and then directly remove the wet brake from the positioning columns 22.
[0030] Furthermore, both sides of the bottom of the tabletop 1 are fixedly provided with support legs 11. Installation holes are opened at the four corners of the bottom of the support legs 11. The setting of the support legs 11 and the installation holes makes it convenient to install and fix the whole device.
[0031] Even further, a stabilizing bearing 17 is sleeved on the outer wall of the rotating shaft 15, and the stabilizing bearing 17 is fixedly connected to the top of the tabletop 1 through a support block. The setting of the stabilizing bearing 17 makes the overall rotation stability of the rotating shaft 15 high.
[0032] It is worth introducing that both sides of one side wall of the pressing plate 32 are fixedly provided with limit rods 33. The limit rods 33 movably penetrate through the support plate 3. The setting of the limit rods 33 makes the movement stability of the electric push rod 31 driving the pressing plate 32 high.
[0033] Such as Figure 1 and 3As shown; the positioning post 22 is a conical column. When positioning the holes on the flange of the brake, it can ensure fitting and positioning with the holes, avoiding looseness and gaps, thus ensuring the stability of the wet brake during the detection process, preventing the wet brake from shaking, and ensuring the accuracy of the test detection.
[0034] As Figure 1 and 2 As shown, a chute is opened on one side of the top of the tabletop 1. A screw rod 4 is rotatably installed in the inner cavity of the chute. The outer end of the screw rod 4 movably penetrates through the tabletop 1 and is fixedly connected with a runner 42. A matching threaded slider 41 is sleeved on the outer wall of the screw rod 4. The top of the threaded slider 41 is fixedly connected with the bottom of the carrier 2;
[0035] After the wet brake is installed, rotating the runner 42 can drive the screw rod 4 to rotate. Thus, by means of screw drive, the threaded slider 41 slides in the chute, driving the carrier 2 and the wet brake to adjust the position, so that the shaft of the wet brake moves to the connection with the coupling 18 for connection. Similarly, during disassembly, it can move in the reverse direction.
[0036] The implementation principle of a wet brake inertia test bench in this application is as follows: In actual use, first place the wet brake on the carrier 2, align the holes on the flange of the wet brake with the positioning posts 22 and put them on, and make the shaft of the wet brake penetrate through the through hole 21 on the carrier 2. Then start the electric push rod 31 to drive the pressing plate 32 to press against one side wall of the wet brake, thus realizing the positioning of the wet brake. Rotating the runner 42 can drive the screw rod 4 to rotate. Thus, by means of screw drive, the threaded slider 41 slides in the chute, driving the carrier 2 and the wet brake to adjust the position, so that the shaft of the wet brake moves to the connection with the coupling 18. Then use the coupling 18 to connect the shaft on the wet brake with the rotating shaft 15. Then start the servo motor 13 to drive the rotating shaft 15 to rotate and perform test operations after speed change by the gearbox 14. During the test, use the wet brake for braking, and then feedback data to the computer through the torque sensor 16, thus realizing the inertia experiment. After the test is completed, retract the pressing plate 32, and then directly remove the wet brake from the positioning post 22.
