Power-closed gear testbed

Abstract

The invention discloses a power-closed gear testbed. The testbed comprises a driving motor, an auxiliary gearbox and a test gearbox, wherein the output end of the driving motor is connected with the auxiliary gearbox; the auxiliary gearbox is connected with the test gearbox; a first transmission shaft and a first rigid shaft are rotationally mounted in the auxiliary gearbox; gears are arranged inthe positions, located at the auxiliary gearbox, of one end of the first transmission shaft and one end of the first rigid shaft, and are in mutualtransmission cooperation. According to the power-closed gear testbed, a square window is formed in a left box body of the test gearbox, and first infrared glass is added for sealing, so that the temperature of the positions where the gears are meshed can be monitored in real time; a rectangular window is formed in the test gearbox and located above a big gear and a pinion, and second infrared glassis sealed, the running state of the gears can be observed in real time, and the temperature of gear surfaces can be monitored in real time; besides, the damage situation of the gear surfaces can be observed without box dismounting, and convenience is provided for users.

Description

technical field [0001] The invention relates to the technical field of mechanical test devices, in particular to a power-enclosed gear test stand. Background technique [0002] The gear is an important part of the mechanical transmission system. The running state of the gear transmission device has a key influence on the entire mechanical equipment. The gear test bench is a test equipment for comprehensive testing of the gear. With the development of the mechanical transmission, the requirements for the gear are getting higher and higher. Therefore, the in-depth research and development of the gear test bench has practical significance; [0003] In the gear test, it can be found that the tooth surface temperature has a great influence on the gear surface damage when the gear meshes. However, the current power-enclosed gear test bench needs to dismantle the gearbox when testing the gear tooth surface temperature, which is time-consuming and laborious. Moreover, the temperatu...

[0003] In the gear test, it can be found that the tooth surface temperature has a great influence on the gear surface damage when the gear meshes. However, the current power-enclosed gear test bench needs to dismantle the gearbox when testing the gear tooth surface temperature, which is time-consuming and laborious. Moreover, it will also affect the test results of the temperature, and it is difficult to test the temperature of the gear surface in real time. Therefore, the present invention proposes a power-enclosed gear test stand to solve the problems existing in the prior art
