Abstract

The utility model discloses a mechanically driven speed reducer for a planetary wheel system, belonging to the technical field of the reducer. The speed reducer comprises a casing, an input shaft with one end extended out of the casing is arranged on the casing, and an eccentric connection disk with the other end being eccentric relative to the input shaft is fixed at the other end of the input shaft, a circular fixed wheel is arranged on the inner surface of the casing, on the casing, an output shaft with one end extended out of the casing is arranged, a flat body is arranged at the other end of the output shaft, a shifting block is arranged on a runner, the flat body, the shifting block and a cross groove board form a cross groove coupler, a supporting eccentric connection disk and a roller are integrated with the casing or fixed on the inner wall of the casing, and a seat sleeve ensuring the input shaft not to bear radial force. The bending moment of the speed reducer can be distributed uniformly, the speed reducer has simple structure, is easy to be produced, and is durable.

Description

Retarder

Technical field

The utility model relates to the retarder of mechanically operated planetary gear train.

Background technique

At present, a kind of retarder of mechanically operated planetary gear train is the input shaft support roller by an off-centre that ZL200320104226.3 discloses, and makees the retarder of friction rolling in fixed wheel, input shaft is subjected to big moment of flexure under the effect of impacting force, the axle easy-rupturing.

Summary of the invention

In order to overcome above-mentioned technical deficiency, the utility model provides a kind of retarder, the manufacturing not only reasonable in design, easy of this retarder, and also durable in use.

For solving its technical problem, the technological scheme that the utility model adopted is: this retarder, one end is set in the side of casing stretches out input shaft outside the casing, input shaft the other end stationary phase is to the eccentric eccentric land that is provided with of input shaft, casing inner surface is provided with annular fixed wheel, one end is set in the another side of casing stretches out output shaft outside the casing, the output shaft the other end is provided with flat body, shifting block is set on the roller, flat body and shifting block insert mutually and connect to form the cross recess shaft joint by the cross frid, support input shaft with casing one or the cover for seat that is fixed on the casing inner wall, be sleeved on and make roller pass through the uniform tooth of outer rim on the cover for seat, it is the eccentric land of the endless rubber belt of trapezoid boss and the trapezoidal groove internal surface friction rolling on the fixed wheel that there are several horizontal uniform cross sections in the outside, respectively roller is located by connecting with input shaft and is in the same place, with the casing one or be fixed on eccentric land of support and roller on the casing inner wall, make input shaft not be subjected to the cover for seat of radial force.

The beneficial effects of the utility model are: this retarder can uniform moment of flexure, only adopts parts such as cover for seat, eccentric bushing, land, and is simple in structure, easily make, and durable in use.
