Problems solved by technology

[0002] At present, when carrying out the contact spot test and the transmission error test on the transmission assembly, it is necessary to use two test benches to conduct two tests respectively, and each test requires re-installation of the test piece, which makes the test efficiency low; and Usually, the transmission error test is done directly. The poor contact state of the gears in the transmission assembly will lead to untrue or inaccurate measurement values ​​of the transmission error.

Embodiment 1

[0028] This embodiment provides a high-precision transmission assembly contact spot and transmission error comprehensive test bench capable of carrying out two tests of contact spot test and transmission error test.

[0029] Such as figure 1 As shown, the test bench includes: a table body 17, a driving assembly and a loading assembly, wherein the table body 17 is used as a supporting platform for deflecting the slide plate 22, the angle misalignment adjustment mechanism 23, carrying the driving assembly and the loading assembly.

[0030] The drive assembly includes: a drive motor 1 , a drive end reducer 2 , a drive headstock assembly 6 and a drive slide 20 . Let the axial direction of the driving assembly be the longitudinal direction, and the direction perpendicular to the longitudinal direction on the support surface of the table body 17 be the transverse direction. The driving slide 20 is installed on the table body 17 through the transverse guide rail, and the drive slide...

Embodiment 2

[0046] A pair of involute gears with ideal shape and infinite rigidity are meshed, and the rotation angle of the driven gear will be consistent with that of the driving gear strictly according to the speed ratio of the two. However, in fact, due to the existence of errors such as gear manufacturing errors, assembly errors, transmission system load deformation, and gear tooth deformation under load, the driven gear rotation angle will lead or lag behind its theoretical rotation angle position at different times, that is, the gear transmission error. In the transmission error test, in order to be closer to the actual working conditions of the gear, on the basis of the above-mentioned embodiment 1, an angle misalignment adjustment assembly is further added to the test bench for the transmission with misaligned meshing gear pairs to be tested. Item 8 is a test for passing errors.

[0047] Such as image 3 As shown, the angle misalignment adjustment assembly includes: a deflection...

Abstract

The present invention provides a contact spot and transmission error comprehensive test bench for a transmission assembly. The test bench integrates the functions of the contact spot test and the transmission error test, the requirement for making two test benches is avoided, and the test efficiency is improved; and at the same time, the contact spot test is conducted before conducting the transmission error test to avoid that the measured value of the transmission error is untrue or inaccurate due to poor contact conditions. The test bench comprises a bench body, an angular misalignment adjusting component, a driving component and a loading component; the driving component is connected with an input shaft of a transmission test piece, and the loading component is connected with an outputshaft of the transmission test piece; and the angular misalignment adjusting component has a gear meshing misalignment quantity simulation function, so that measurement on the transmission error of asingle pair of gears in the presence of misalignment conditions can be realized.

Description

technical field [0001] The invention relates to a test bench, in particular to a comprehensive test bench for contact spots and transmission errors of a transmission assembly. Background technique [0002] At present, when carrying out the contact spot test and the transmission error test on the transmission assembly, it is necessary to use two test benches to conduct two tests respectively, and each test requires re-installation of the test piece, which makes the test efficiency low; and Usually, the transmission error test is done directly. The poor contact state of the gears in the transmission assembly will lead to untrue or inaccurate measurement values ​​of the transmission error. Contents of the invention [0003] In view of this, the present invention provides a comprehensive test bench for contact spot and transmission error of the transmission assembly, the test bench integrates the functions of contact spot test and transmission error test, avoiding the need to ...
