Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The present embodiment provides a kind of multistage nested type transmission devices, including moving person 1, retaining ring 2, with the involute of external tooth
Spline housing 3, gear shaft 4 and involute spline set 5 and circlip groove 6 with interval tooth section.
Above-mentioned moving person 1 is the gear shaft (referring to Fig. 5) of two gear segment of band, and the both ends of every section of gear segment are all arranged
There is circlip groove 6；Involute spline set 3 with external tooth is sheathed on any gear segment of moving person 1, the involute flower with external tooth
It is provided with involute spline tooth on the outer ring of key set 3, the spline tooth socket matched with its spline tooth is provided on inner ring (referring to figure
3)；The gear shaft 4(is referring to Fig. 6) it is arranged in parallel with moving person 1, the both ends of gear segment are provided with circlip groove 6；Band interval
