Abstract

The invention relates to the technical field of gears, in particular to a transmission gear set and a speed reducer. The transmission gear set comprises a driving gear and a driven gear, or comprises an outer gear and an inner gear, wherein the outer gear and the inner gear are respectively a first gear and a second gear; the first gear is provided with a plurality of first teeth; the second gear is provided with a plurality of second teeth; the first teeth and the second teeth are meshed and can complete rotation; the shapes of the peripheries of the first gear and the second gear are tooth profiles; the first teeth and the second teeth are respectively provided with reference circles respectively; the tooth profile of the outer side of the reference circle of the first gear is a section of cosine curve; the two sides of the cosine curve are matched with the two sides of the first teeth, and the cosine curve is a first cosine curve; the tooth profile of the inner side of the reference circle of the first gear is a cosine curve; the two sides of the cosine curve are matched with the two sides of the first teeth, and the cosine curve is a second cosine curve; and the height of the second cosine curve is 1.05-1.15 times that of the first cosine curve. The transmission gear set has the advantages of being high in transmission efficiency and stable in power transmission.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a transmission gear set and a speed reducer. Background technique [0002] The transmission gear set includes a driving gear and a driven gear, or includes an external gear and an internal gear, which are respectively a first gear and a second gear, the first gear has a plurality of first teeth, and the first gear has a plurality of first teeth. The second gear has a plurality of second teeth, the meshing of the first teeth and the second teeth can complete the rotation of the driving gear and the driven gear, and the shape of the outer circumference of the first teeth and the second teeth is a tooth profile. [0003] The shape of the gear tooth profile is various, such as multi-arc and involute, but they all have disadvantages such as unsmooth transmission, high vibration and noise, low efficiency, and short service life. Contents of the invention [0004] The purpose of the pr...
