Description

The invention relates to gears and may be used. mechanical engineering and instrument making,; The purpose of the invention is to increase reliability and durability by reducing the load on the driven shaft supports and reducing the axial dimensions of the gear.

The drawing shows a planetary concession gear.

The transmission includes a housing, input 2 and output 3 shafts, a precessional conic A and a fixed conical 5 wheel. The input shaft is 2 by 1 (1 bearing 6 is located inside the if-shaft 3.

; Inside the input shaft 2 there is a carrier 7, made in the form of an eccentric bore, in which a bearing 8 is installed, which serves as a support for the shaft of a concession conical Roro wheel 4j, the latter of which is a gear shaft, the end of which has a shaft equal to koro resistors and is installed in side 7 and the other end is connected to (universal joint 9, the inner and outer elements of which are ijienteHbi in the body of the output shaft 3j which is mounted in housing 1 on the bearings 10 and 11 and are complete of two parts centered Bearings-: 6 ohm and rigid 4oboy connected between one of the portions vyhbdnogo Ba Jia 3 has a fork with .zub mi, 1 azmescheny which in openings precessional bevel gear 4 for rigid connection to another part.

The transmission works as follows.

The input shaft 2, mounted on bearings 6, rotates the bearing 8 from the eccentric drive in a circle, resulting in precession

The conical wheel 4, rolling on the stationary conical wheel 5, performs precessional movements around the center of the hinge 9.

As a result of the difference in the number of teeth of the bevel gears, the precession bevel wheel 4 enters with reduction and rotates the output shaft 3 by means of the hinge 9.

Claims (2)

1. A planetary precessional bevel gear containing input and output shafts, the first of which is installed inside the second, carrier, stationary bevel wheel, precessional bevel wheel connected by means of a universal joint to the output shaft for interacting with the fixed bevel wheel, that, in order to increase reliability and durability by reducing the load on the bearings of the driven shaft and reduce the axial dimensions of the gear, the carrier is placed inside the output shaft, the precession conical wheel is a gear shaft, one end of which has a shaft of equal resistance and is installed in the water, and the universal end is connected to the universal hinge with the output shaft. the hinge is placed in the carrier. 2. Transmission according to clause I, that is, that is that the output shaft is two-piece, one of which has a fork with teeth for dl. rigid connection with another part of South Africa, in the precession wheel, openings were placed to accommodate the teeth of the fork.
