Abstract

The invention belongs to the technical field of gear fatigue test, and particularly relates to a gear fatigue test clamp. The gear fatigue test clamp comprises a tested gear mounting shaft, a loadinggear, a loading gear mounting shaft and a gearbox; the tested gear mounting shaft and the loading gear mounting shaft are arranged side by side, the two ends of the tested gear mounting shaft and thetwo ends of the loading gear mounting shaft are supported on the gearbox, the outer side of the loading gear is provided with a loading gear position adjusting device for adjusting the distance between the loading gear and the tested gear, one end of the loading gear position adjusting device is connected to the loading gear mounting shaft, and the other end is in threaded connection with the gearbox.

Description

technical field [0001] The invention belongs to the technical field of gear fatigue test and the like, and in particular relates to a gear fatigue test jig. Background technique [0002] In gear design, especially for gears with high reliability requirements, the results of evaluating the safety factor based on reliability theory can hardly reflect the reliability level of gears at all. Therefore, it is usually necessary to carry out fatigue tests on gears to check the reliability and durability of gears, especially so. [0003] Existing fatigue testing machines for gear fatigue tests use the following method to perform fatigue tests on gears: first, fix the gear to be tested on a fixture shaft; Then, use a pressure head tool with appropriate hardness to load a tooth top at the above control point for fatigue test. [0004] In the above-mentioned gear fatigue test, only one fixed position of the gear to be tested can be tested, and the fatigue test cannot be performed on e...
