Problems solved by technology

[0002] At present, the gear transmission structure has always had many problems for high-power transmission, such as bulky volume, fast wear of parts, high noise, weak load-carrying capacity, short life, and poor reliability. The load-carrying capacity of the transmission is limited by the way of lifting, so that the face gear often needs to increase the gear diameter to obtain a greater load-carrying capacity in the transmission, which will inevitably lead to an increase in the size of the transmission

Abstract

The invention provides a nutation surface gear transmission structure which is similar to the petal structure of a lotus flower in the natural world and can form multiple contact lines, motion and power transmission is completed, and a parallel shaft output symmetric variable-speed gear transmission device can be formed. Through the design of the symmetrical structure, parts of axial loads generated when a nutation disc moves is offset, and the advantages of the compact structure, large coincidence, the small volume, few parts, the large transmission ratio, strong bearing capacity and the likeare achieved, and the symmetrical structure variable-speed transmission device having the good application prospect is realized in the high-power fields such as helicopters and shield machines.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a variable speed transmission device in the field of high-power transmission. Background technique [0002] At present, the gear transmission structure has always had many problems for high-power transmission, such as bulky volume, fast wear of parts, high noise, weak load-carrying capacity, short life, and poor reliability. The bearing capacity of the transmission is limited by the way of lifting, so that the face gear often needs to increase the gear diameter to obtain a greater bearing capacity in the transmission, which will inevitably lead to an increase in the size of the transmission device. Contents of the invention [0003] According to the technical problems raised above, a new type of space gear transmission developed in combination with the principle of nutating gear transmission is provided, which has the characteristics of small size, light weight, low ...
