Problems solved by technology

The gear modification method requires the use of relatively high-precision equipment, and the process is relatively complicated
Therefore, the input cost is high and the manufacturing difficulty is great
Especially with the prolongation of the use time, after long-term meshing wear, the gear precision is reduced, and the knocking energy between the gears will generate gear noise, and the effect of reducing gear noise is unstable.

Abstract

The invention discloses a gear torsional vibration absorber structure comprising an input gear (1), a bearing (3) a spring driving rack (4) and an input shaft (31) which are sequentially sleeved from the outside to the inside, a spring driven rack (5), a disc spring (2) and a damping element (8), wherein the excircle of the spring driven rack (5) is sleeved in an annular connecting trough (1-2) of a gear; the disc spring (2) is arranged in a mounting slot (1-1) of the gear, and the other end of the disc spring (2) is tightly adhered to a limiting column body (31-1) of an input shaft (31); the damping element (8) is arranged between the annular connecting trough of an output gear and one side of outer splines (4-1) of the spring driving rack; a mounting slot (4-2) is formed among the adjacent outer splines (4-1) on the excirlce of one end of the spring driving rack; inner splines (5-1) on the inner circle of the spring driven rack extend into the mounting slot (4-2); two sides of the mounting slot (4-2) are provided with spring fixing blocks (9) for fixing vibration damping elements (6). The gear torsional vibration absorber structure and gear torsional vibration method disclosed by the invention has the beneficial effect of reducing meshing noises.

Description

technical field [0001] The invention relates to a structure of a torsional shock absorber, in particular to a structure of a torsional shock absorber for a gear. [0002] The invention also relates to a gear torsional vibration damping method. Background technique [0003] At present, most automotive transmissions use gear transmission as the power transmission method. With the implementation of laws and regulations such as fuel consumption and emissions, engines with low displacement and high torque are becoming more and more popular, and the number of cylinders of the engine is also switched from 4 cylinders to 3 cylinders. , which undoubtedly leads to greater torsional vibration in the transmission system, and thus the unavoidable problem of gear noise generated by the knocking energy between the gears. At present, to solve the problem of gear noise, it is mainly to improve the machining accuracy of gears and the meshing accuracy of gears through gear modification method...
