The invention discloses a transmission case detection device, which is used for detecting a transmission case. The transmission case includes at least two transmission shafts, between which power can be passed on. The transmission case detection device comprises a detection frame and a driving mechanism. The transmission case can be fixed on the detection frame. The driving mechanism can be connected with the transmission shafts of the transmission case to drive the transmission shafts to rotate. The detection device also includes a radial load applying mechanism to apply radial acting force to the transmission shafts. In the preferential technical proposal, the detection device also includes an impact load applying mechanism to apply impact acting force to the transmission shafts. The stress environment simulated by the detection device provided in the invention can not only have torque load, but also have radial load and / or impact load and the simulated stress environment is closer to the actual stress environment of the transmission case. Therefore, the detection parameters obtained in the detection process are more reliable and furthermore, the performance of the transmission case can be judged better.
Description
Technical field [0001] The invention relates to a detection device, in particular to a gearbox detection device. Background technique [0002] As an important power transmission component, gearboxes are widely used in automobiles and machine tools. The gearbox is responsible for the task of transmitting power and changing the speed and torque. Therefore, the performance of the gearbox is directly related to the running performance of automobiles and machine tools. [0003] In order to ensure the performance of the gearbox, before launching a type of gearbox, it is necessary to test and verify the rationality of the design of its key components, the performance of the materials used, and the fatigue strength to eliminate or reduce structural defects; During mass production, it is also necessary to test the performance of the gearbox to discover possible defects during manufacturing and assembly in time to prevent greater losses. [0004] The performance of the gearbox can be tested ...
