Description

Technical Field

[0001] The utility model relates to the technical field of motor brake test equipment, in particular to a motor brake test lever. Background Technique

[0002] In the prior art, a lever is required for motor brake testing.

[0003] For example, in the prior art, in a Chinese patent document with the authorization announcement number CN205958254U, a conical motor brake test lever is recorded. The patent includes a lever body, on which a pressing part for applying axial pressure to the end of the output end of the motor rotating shaft and an extending structure for extending into the inner side of the inwardly turned edge of the motor housing are arranged at intervals along the extending direction of the lever body. The extending structure has a pushing part for pushing and cooperating with the inwardly turned edge of the motor housing. The lever body has an input end for inputting external force. By applying an external force at the input end, the axial movement of the motor rotating shaft and the axial reset of the motor rotating shaft when the external force is removed are used to simulate the starting and braking processes of the motor, so as to judge whether the starting performance and braking performance of the motor meet the requirements. The entire brake test process does not require power supply, saving the wiring process and the process of installing and fixing the motor, and the test efficiency is high.

[0004] However, in the prior art, the distance between the extending plate and the conical tip is fixed. Since the distances between the output shaft and the housing in different models of motors are different, the lever set is difficult to be applicable to different models of motors, and the applicability is low. And the extending plate is a vulnerable structure. In the prior art, when the extending plate is damaged, the entire lever needs to be replaced, resulting in a high cost.

[0005] Therefore, we propose a motor brake test lever. Content of the Utility Model
