Abstract

The invention discloses an internally meshed variable-tooth-thickness gear test bench, which comprises a base. The front and back of the base are respectively provided with a transverse adjusting plate and an output shaft bearing seat. The output shaft bearing seat is provided with a front bearing fixed position and a rear bearing fixed position and is used for the installation of an output shaft. The front end of the output shaft is fixedly provided with a variable-tooth-thickness inner gear fixing disk. The upper surface of the transverse adjusting plate is provided with an input shaft fixed end bearing seat and an input shaft mobile end bearing seat and is used for the installation of an input shaft. The upper part of the input shaft mobile end bearing seat is provided with a square opening. An adjustment inclined block is arranged inside the square opening. The output shaft bearing seat, the transverse adjusting plate, the input shaft mobile end bearing seat and the adjustment inclined block are respectively connected with a corresponding handle adjusting mechanism. According to the technical scheme of the invention, the included angle, the central distance and the gear axial position of a variable-tooth-thickness gear shaft can be finely adjusted. Therefore, the test bench can be used for the research on the parallelism error, the shaft spacing deviation, the influences of different axial distances on the performances and the transmission precisions of internally meshed variable-tooth-thickness gear pairs and the like.

Description

technical field [0001] The invention relates to a transmission test bench, in particular to a variable tooth thickness gear test bench. Background technique [0002] Gear is an important part of mechanical equipment, a mechanical part that transmits motion and power, and is widely used. The internal mesh variable tooth thickness gear is a general form of internal mesh gear transmission, and its geometric characteristics are: there are different coefficients of variation on different end sections of a gear. As the requirements for the reduction ratio of the reducer continue to increase, a large number of reducers begin to use internal meshing gears with variable tooth thickness, but the center distance deviation and parallelism error will affect the contact meshing state of the gear pair. [0003] Chinese patent document 17N 105910817 15 disclosed a variable tooth thickness gear test bench on August 31, 2016. It includes a base plate on which two opposite input shaft bearing...
