Description

Technical Field

[0002] Generally, for motor load testing, a certain amount of load is applied to the motor to be tested for long-term operation. During the operation, the magnitude of the load cannot be adjusted at any time, and the reloading of the load needs to be carried out after the operation stops.

[0003] In the prior art, reference can be made to the Chinese patent with the publication number CN 109738800 B, which discloses a motor load testing tooling, including a tooling base. A test motor mounting seat and a vertically arranged connecting column are provided on the tooling base. A test motor is placed on the test motor mounting seat. A test motor output shaft is vertically upwardly arranged on the test motor. A moving assembly is provided on the connecting column. A test motor driven shaft bearing mounting seat and a brake assembly are provided on the moving assembly. Through the braking principle, the utility model can adjust the operation of the test motor from no-load to different load conditions by controlling the tightness state of the brake, so as to flexibly realize the adjustment of the load simulation in different states and effectively optimize the test conditions.

[0004] This comparative document provides a motor load testing tooling. However, when adjusting the load of the motor test in the above patent, the friction force generated by the braking principle is used to increase or decrease the load condition of the motor. Since the load at the output end of the motor is a fixed value and the complexity at the start of the motor is fixed, it is impossible to test the load condition at the start of the motor under different load conditions.

[0005] Therefore, a motor load testing tooling with a brake assembly is proposed. Summary of the Utility Model

[0021] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] The embodiment of the present utility model provides a motor load test tooling with a brake assembly, as Figures 1-4As shown in the figure, it includes a base 1. A motor mounting table 2 is welded to the top of the base 1. And a first bearing support table 3 and a second bearing support table 4 are fixedly connected to one side of the top of the base 1 close to the motor mounting table 2 by bolts. The first bearing support table 3 is located between the motor mounting table 2 and the second bearing support table 4. A rotating shaft 5 is rotatably penetrated through the first bearing support table 3 and the second bearing support table 4. The rotating shaft 5 penetrates through the first bearing support table 3 and the second bearing support table 4. A brake disc 6 is welded to the outer wall of one side of the rotating shaft 5 at a position between the first bearing support table 3 and the second bearing support table 4. And a load disc 7 is welded to the other end of the rotating shaft 5. A fixing plate 81 in a brake assembly 8 is fixedly connected to one side of the top of the base 1 close to the brake disc 6 by bolts. There are two fixing plates 81 in total, and the two fixing plates 81 are symmetrically arranged on the top of the base 1. A hydraulic cylinder 82 is fixedly connected to the outer wall of one side of the fixing plate 81 away from the brake disc 6 by bolts. The output end of the hydraulic cylinder 82 is fixedly connected to a transverse moving plate 83. A brake pad 84 is welded to the outer wall of one side of the transverse moving plate 83 away from the output end of the hydraulic cylinder 82. A connecting plate 91 in a counterweight assembly 9 is welded to the outer wall of one side of the load disc 7. There are four connecting plates 91 in total, and the four connecting plates 91 are symmetrically arranged on the outer side wall of the load disc 7. A counterweight block 92 is fixedly connected to the outer wall of one side of the connecting plate 91 away from the load disc 7 by a nut. A motor 10 is fixedly connected to the top of the motor mounting table 2 by bolts.

[0023] It should be noted that since the load at the output end of the motor in the existing motor load test tooling is a fixed value and the complexity at the start of the motor is fixed, it is impossible to test the load condition at the start of the motor under different load conditions. In this embodiment, the counterweight assembly 9 can replace the counterweight blocks 92 with different weights according to the test condition of the starting load of the motor 10, and then adjust the load disc 7 to the required load amount, so as to test the starting load value of the motor 10 under different load conditions. And the brake assembly 8 can adjust the motor 10 from no-load to different load working conditions to realize the adjustment of the load simulation situation in different states.

[0024] Specifically, in this embodiment, the solution mainly includes a brake assembly 8 and a counterweight assembly 9. When in use, the motor 10 is fixed to the top of the motor mounting table 2 by bolts, and the output end of the motor 10 is key-connected to one end of the rotating shaft 5. When conducting a load test on the motor 10, a counterweight block 92 of an appropriate weight is selected according to the required load, and the counterweight block 92 is installed and fixed on the connecting plate 91. During the load test of the motor 10, the output end of the motor 10 drives the rotating shaft 5 to rotate, and the load disk 7 at one end of the rotating shaft 5 rotates synchronously. Since the load disk 7 has a large weight, the torque of the motor 10 can be load-tested, and the rotational load of the rotating shaft 5 is controlled by the brake assembly 8. Specifically, the hydraulic cylinder 82 drives the horizontal moving plate 83 and the brake pad 84 to move horizontally through its output end. The brake pad 84 contacts the brake disk 6, and by continuously increasing the extrusion force to increase the frictional resistance, the motor 10 can be adjusted to operate from no-load to different load conditions, flexibly realizing the adjustment of the load simulation in different states, and also enabling the brake disk 6 to stop rotating.

[0025] In a further preferred embodiment of the present invention, as Figure 1 shown, the cross-section of the brake pad 84 is an arc-shaped structure, and the centers of the brake pad 84 and the brake disk 6 are on the same horizontal axis.

[0026] In this embodiment, through the brake pad 84 and the brake disk 6 on the same horizontal axis, the brake pad 84 can contact the brake disk 6 during the horizontal movement process, and the rotating brake disk 6 is stopped by the frictional resistance.

[0027] In a further preferred embodiment of the present invention, as Figure 1 shown, the output end of the motor 10 is key-connected to the other end of the rotating shaft 5.

[0028] In this embodiment, the connection between the motor 10 and the rotating shaft 5 can be realized, thereby realizing the load setting of the motor 10, which is convenient for subsequent load tests.
