Combined herringbone gear structure

Abstract

The invention relates to a combined herringbone gear structure, which comprises a shaft, a right-handed rotation single helical gear and a left-handed rotation single helical gear, wherein the right-handed rotation single helical gear and the left-handed rotation single helical gear have opposite rotation directions, the combined herringbone gear structure also comprises a separation ring arranged between the right-handed rotation single helical gear and the left-handed rotation single helical gear, and the right-handed rotation single helical gear, the left-handed rotation single helical gear and the separation ring are matched and connected with the shaft through splines. Through the combined herringbone gear structure, the split forging beating can be adopted, the processing method is flexible, the options of processing machine tools are many, the processing time is saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a combined herringbone gear structure. Background technique [0002] At present, most of the herringbone gears on the market are formed by integral forging, which can be used when the diameter is relatively small, but if the integral type is used for large diameters, first, the weight of the forging is very large, and the cost is very high. Second, gear hobbing, grinding The bearing weight of the teeth is limited, and the integral herringbone gear hobbing and gear grinding require a much larger machine tool, which increases the cost and does not necessarily require outsourcing of processing equipment. The left-handed gear and the right-handed gear of the shaft of the herringbone gear form herringbone teeth and are located in the middle of the shaft. The distance between the two teeth is at most only the undercut. Equipment requirements are higher. Contents of the invention ...
