Abstract

The invention relates to the technical field of gears, and provides a composite cosine tooth form internal meshing transmission gear. The composite cosine tooth form internal meshing transmission gearcomprises an inner gear and an outer gear, and a single tooth profile of a composite cosine inner gear is formed by sequentially connecting a first inferior arc, a first cosine curve segment and a second inferior arc; the single tooth profile of a composite cosine inner gear is smoothly connected by the first inferior arc and the first cosine curve segment, and the second inferior arc is smoothlyconnected with the first cosine curve segment; and the circle center of a circle where the first inferior arc and the second inferior arc of the single tooth profile of the composite cosine inner gear is located is concentric with a reference circle of the composite cosine inner gear, and the radii of the first inferior arc and the second inferior arc are the same. The composite cosine tooth forminternal meshing transmission gear has the advantages of high transmission efficiency and stable power transferring.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to internal meshing transmission gears. Background technique [0002] There are three types of gears: internal gears, external gears, and rack and pinion. Compared with external gearing, internal gearing has the advantages of compact structure, small volume, and high load-carrying capacity, so it is widely used in planetary gear mechanisms. The shape of the gear tooth profile has an important impact on the stability, noise, efficiency and service life of the gear during operation; in the prior art, there are various gear tooth profiles, such as those with multiple arcs and involutes However, they all have the disadvantages of unstable transmission, high vibration and noise, low efficiency, and short service life. Contents of the invention [0003] The object of the present invention is to provide a compound cosine-tooth-shaped internal meshing transmission gear with stable transmi...
