Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0039] It should be noted that: first, in the present invention, unless otherwise specified, the radial direction is the radial direction relative to the transmission shaft of the gearbox; second, the detection frame is not limited to a whole, and may include relative Multiple sections that are independent and fixed to the work environment.

[0040] refer to figure 2 , figure 2It is a structural schematic diagram of the transmission detection device provided in the first embodiment of the present invention in a top view direction. The transmission detection device provided in this embodiment includes a detection frame 200 , a hydraulic motor 5 , a variable hydraulic pump 6 , a radial load applying mechanism 1 an...

Abstract

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 transmission detection device. Background technique [0002] As an important component for transmitting power, gearboxes are widely used in automobiles and machine tools. The transmission is responsible for transmitting power and changing the speed and torque. Therefore, the performance of the transmission is directly related to the operation 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 detect possible defects in manufacturing and assembly in time to prevent greater losses. [0004] Testing the performance of the ge...
