Embodiment Construction

[0025] Such as Figure 1-Figure 6 As shown, the face gear bending fatigue test mechanism is composed of a loading part and a supporting part. The loading part includes a loading rod 1, a loading indenter 11 installed on the loading rod 1, and the supporting part includes a face gear support shaft 6, which is installed on a face gear support. The rocker 10 on the shaft 6, the support rod 2, the support pressure head 12 installed on the support rod 2, the installation plate 3, the axial adjustment plate 8, the right bracket 4 and the left side bracket installed on the axial adjustment plate 8 Bracket 7 , screws for fixing the axial adjustment plate 8 on the mounting plate 3 . The loading head 11 and the support head 12 are both involute toothed, so as to ensure that the gears on the surface to be tested are tightly meshed with the involute toothed loading head 11 and the involute toothed supporting head 12 respectively. .

[0026] During the test, install the mounting plate 3 ...

Abstract

The invention relates to face-gear bending fatigue test mechanism and method, and belongs to the field of measurement of gear bearing capacity. The face-gear bending fatigue test mechanism disclosed by the invention meets the meshing relation of face-gears by using an involute profile loading press head and an involute profile supporting press head and can be used for loading any loading points positioned on the face-gears, thereby solving the problem that the traditional loading head can not meet the meshing relation and complicatedly transmits loading force; and besides, the face-gear bending fatigue test mechanism disclosed by the invention has adjustability and is suitable for a face-gear tooth bending fatigue test with different parameters by adjusting the positions of a supporting assembly and a loading assembly which are positioned in the face-gear bending fatigue test mechanism, thereby achieving obvious substantiality characteristics and outstanding advancement.

Description

[0001] technical field [0002] The invention relates to a face gear bending fatigue test mechanism, which belongs to the field of gear bearing capacity measurement. Background technique [0003] Gears are important transmission parts in the field of mechanical transmission. The quality and life of gears directly affect the stability and efficiency of the transmission system. Among them, the gear that meshes with the cylindrical gear and realizes the space orthogonal transmission is called the face gear, such as image 3 . Compared with bevel gear transmission, face gear transmission has the following advantages: the coincidence degree of face gear transmission is larger than that of bevel gear transmission, which can reach 1.6-1.8 under no load; The transmission ratio of the transmission fluctuates within a certain range, so the vibration and noise of the face gear transmission are smaller than that of the bevel gear transmission; the gear meshed by the face gear is an inv...
