Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, specifically relating to a running-in tooling. Background Technology

[0002] A speed reducer is a mechanical device widely used in industrial equipment that reduces speed and increases torque through transmission elements such as gears. It typically includes components such as an input shaft, an output shaft, a gear set, bearings, and a housing.

[0003] Before a speed reducer is assembled and put into formal use, it must undergo a running-in test. This involves running it at low speeds, under light loads, or with gradual loading to ensure that the surfaces of moving parts such as gears and bearings achieve a good fit, reducing initial wear and improving operating efficiency and lifespan. The running-in equipment needs to be able to simulate the actual working conditions of the speed reducer, including precise control of parameters such as speed. Modern running-in equipment typically uses PLC or computer control to automate the running-in process, including parameter setting, data acquisition, and fault diagnosis. Sensors are used to monitor the speed reducer's vibration, temperature, noise, and other parameters in real time to evaluate the running-in effect and ensure running-in quality.

[0004] The existing running-in fixture involves installing the actual motor on the reducer for running-in testing. After the test, the motor is removed, and the reducer is painted and packaged. The original motor is heavy and large, making the installation process cumbersome and slow.

[0005] Chinese patent publication number CN106840664A, entitled "A No-Load Running-In Test Device for a Reducer," includes a variable frequency motor, a connecting plate, a pressure plate assembly, a frequency converter, and a working platform. The working platform is fixed to a ground foundation. The rotary drilling rig reducer to be tested under no-load conditions can be placed on the working platform and secured by the pressure plate assembly. The pressure plate assembly can secure different models of reducers. The reducer is connected to the variable frequency motor via the connecting plate. The output shaft of the variable frequency motor is connected to the input shaft of the reducer and drives the input shaft of the reducer to rotate. The frequency converter is connected to the variable frequency motor and controls the speed of the variable frequency motor. The installation process of this patent application uses bolt fixing, which is slow. Utility Model Content
