Description

The invention relates to mechanical engineering, namely to friction planetary gears, which can be used in various branches of engineering.

The purpose of the invention is to enhance the transmission functionality and increase its reliability by adjusting the rotational speed of the output shaft and balancing the load on the output shaft by introducing into the transmission an additional drive shaft and a cam balance mechanism.

The drawing shows a functional planetary gear, a general view. The transmission includes a housing 1, coaxial main 2 and additional 3 drive shafts and a driven shaft 4, two central wheels 5 and 6, the first of which is connected with the outer conical surface with the main drive shaft 2, the second with the inner conical surface with an additional - a telescoped drive shaft 3, and a carrier 7 with conical satellites 8. The carrier 7 is connected to the driven shaft 4 and mounted on supports in the housing 1. On the driver 7, the cam 9 of the cam balancing mechanism 10 is rigidly mounted, the plunger 11 of which is spring-loaded with an elastic element 12 o for housing 1.

The friction preload is carried out by the rod 12 through the bearing 13. The main drive shaft 2 is connected to the shaft of the main engine 14, and the additional drive shaft is the 3rd shaft of the auxiliary engine 15.

The friction planetary gear works as follows.

When the engines 14 and 15 are operated, the primary 2 and additional 3 drive drive shafts are rotated. Summation of two motions from va

Fishing gears 2 and 3, connected respectively to the central wheels 5 and 6, take place on the planetary gear carrier 7 and are transmitted to the driven shaft. When the driven shaft 4 rotates, the cam 9 rotates, shaped in such a way that the spring-loaded pusher 11, interacting with the cam 9, balances the driven shaft 4 loaded with an external load.

A change in the rotational speed of the main 14 and an additional 15 engines provides a wide range of rotational frequencies of the output shaft 4 and creates favorable opportunities for reducing dynamic loads on the output shaft 4, which, together with the balancing effect, increases the reliability of the transmission.
