Power-closed small angle intersecting shaft gear test bench

Abstract

The invention discloses a power-closed small angle intersecting shaft gear test bench which comprises an electric motor, an auxiliary gear box, a moving platform, a rotating platform and intermeshingtest gear I and test gear II. Each part of the test bench constitutes a power-closed system to compensate for lost power. The movement of one test gear in directions of two degrees of freedom of X andY is achieved through the moving platform, the angular rotation of the other test gear is achieved through the rotating platform, the parallel shaft installation of a thickened gear and the intersection shaft installation in a certain angle range can be satisfied, and a shaft crossing angle error and a mounting distance error of the thickened gear are simulated. The contact spot, transmission error, transmission efficiency, vibration and the like of the high-speed thickening gear can be tested. At the same time, the test bench also be used for studying the influence of the shaft crossing angle error and the mounting distance error on the meshing performance of the thickened gear.

Description

technical field [0001] The invention belongs to the field of gear test benches, in particular to a power-enclosed type small angle intersecting axis gear test bench. Background technique [0002] The intersecting axis thickening gear transmission is a new type of gear transmission, which can adjust the backlash by adjusting the axial position to change the gear backlash, and has many advantages such as high precision, small backlash, high strength, and good rigidity. However, in actual engineering, due to the existence of processing and installation errors, the contact state of the thickened gear pair will be greatly affected, and its meshing performance will be affected, especially the installation distance error and the shaft angle error. [0003] At present, most of the existing variable-thickness gear test benches are fixed-shaft intersection angles, and the power of the whole machine is open. The vibration and efficiency tests of the whole machine are mainly carried out...

However, in actual engineering, due to the existence of processing and installation errors, it will have a great impact on the contact state of the thickened gear pair, affecting its meshing performance, especially the installation distance error and shaft angle error

[0003] At present, most of the existing variable-thickness gear test benches are fixed-shaft intersection angles, and the power of the whole machine is open. The vibration and efficiency tests of the whole machine are mainly carried out. There is no test bench suitable for measuring the meshing characteristics of variable-thickness gear pairs with adjustable intersecting axes.
