Abstract

The invention discloses a service life experimental machine of an one way clutch, and the service life experimental machine comprises a control system, a drive system, a loading system, and a data collecting system; wherein, a computer of the control system controls a stepper motor (11), a tested piece (3) on the control chief axis (15) is indexed, and the locating of the chief axis (15) during the loading process is finished by the help of a ratchet chain; the computer adjusts the burden of a loading oil cylinder (14) by controlling a proportioning valve, the loading oil cylinder (14) is circularly loaded through housing (4), and the load, load keeping and the unload process are finished; the stress signal of a pull pressure sensor (13) collected by a signal collecting card is fed back to the computer to adjust the proportioning valve to control the burden output of the loading oil cylinder (14), and the accuracy of the loading burden is ensured; an angular transducer (7) is utilized to make the discretion for whether the one way clutch is out of work or not by adopting the control of the computer, the complete machine has simple structure, friendly interface, and convenient operation; the joggle service life evaluation of the one way clutch can be correctly and reliably realized.

Description

Technical field: [0001] The invention relates to the technical field of one-way clutch testing, and relates to a one-way clutch life testing machine. Background technique: [0002] At present, as domestic one-way clutches are more and more widely used, higher requirements are put forward for key technical indicators such as the working life of the product, that is, the meshing life. In practical applications, due to different working conditions, there are large differences in working life. The evaluation method of meshing life in the design of one-way clutch is mainly calculated from the perspective of material contact stress, and the evaluation of its comprehensive performance lacks corresponding test data support. Even in the meshing life of high-reliability one-way clutch The assessment test is also completed through relatively simple test conditions, and the test data lacks accuracy and integrity. Due to the lack of complete one-way clutch life test equipment guarantee...
