Abstract
The utility model relates to a cycloid pin wheel speed reducer with an output axle system simply supported beam structure. The utility model comprises a machine body, an input axle, an input end cover, a cycloid gear, a pin gear casing, a pin gear, an output pin axle, an output axle, an output bearing, and a camshaft bearing; the input axle is arranged at the middle of the machine body through the camshaft bearing, the cycloid gear is meshed with the camshaft bearing, the pin gear in the pin gear casing is arranged outside the cycloid gear, the output pin axle is arranged outside the pin gear casing, the input end cover is arranged at the front end of the input axle, the output axle is connected with the input axle, and two output bearings are arranged on the output axle; the utility model is characterized in that an input gear is arranged between the two output bearings, the end head of the input axle is arranged in the machine body through a blocking ring and an end bearing, and a stuffy cover is arranged at the top end of the output axle. The utility model has the advantages that the cycloid pin wheel speed reducer can be still utilized even if the utility model is used under a bigger radial force, and the cycloid pin wheel speed reducer can be also used when the gear and sprocket wheel output is adopted.
Description
Technical field
The utility model relates to a kind of cycloidal planetary gear speed reducer that output shaft is a simple beam structure that has, and makes the output shaft of cycloidal planetary gear speed reducer can bear bigger radial load, belongs to the cycloidal planetary gear speed reducer technical field.
Background technique
Usually the general employing of cycloid speed reducer is as the structural type of Fig. 1, by body 1, input shaft 2, input end cap 3, cycloidal gear 4, pin wheel housing 5, pin tooth 6, output bearing pin 7, output gear 8, output shaft 9, two output bearings 10, capacity eccentric bearing 11, its shortcoming is that output shaft is a cantilever structure, two output distance between bearings are less, can not bear radial load, and general output torque is quite big, its radial load is also bigger, cause speed reducer to lose efficacy easily, especially when adopting gear, sprocket wheel output, its radial load can't overcome.
Summary of the invention
Under the operating mode situation of big radial force, still can use when the purpose of this utility model provides a kind of output and unlikely inefficacy have a cycloidal planetary gear speed reducer that output shaft is a simple beam structure.
For realizing above purpose, the technical solution of the utility model provides a kind of cycloidal planetary gear speed reducer that output shaft is a simple beam structure that has, comprise body, input shaft, the input end cap, cycloidal gear, pin wheel housing, the pin tooth, the output bearing pin, output shaft, the output bearing, capacity eccentric bearing, input shaft is located at the centre of body by eccentric bushing and capacity eccentric bearing, cycloidal gear and capacity eccentric bearing engagement, pin tooth in the pin wheel housing is located at outside the cycloidal gear, pin wheel housing is provided with the output pin axle outward, the input end cap is located at the front end of input shaft by input shaft envelope and input bearing, output shaft is connected with input shaft by the input auxiliary bearing, on output shaft, be provided with two output bearings, it is characterized in that, be provided with output gear between two output bearings, the termination of output shaft is located in the body by baffle ring and step bearing, and the top of output shaft is provided with stifle.
The utility model strengthens the output distance between bearings on the output shaft on the basis of original cycloid speed reducer, output gear is installed in the centre of two output bearings, the termination that makes output shaft simultaneously is in body, make original cantilever structure become simple beam structure, improved the stress of output shaft, make output shaft can bear bigger radial load, prolonged the working life of cycloid speed reducer and enlarged use occasion.
Even under the operating mode of big radial force, still can use and unlikely inefficacy when the utility model has the advantages that output, when adopting gear, sprocket wheel output, also can use.
Description of drawings
Fig. 1 is former cycloidal planetary gear speed reducer structural representation;
Fig. 2 is a kind of cycloidal planetary gear speed reducer structural representation that output shaft is a simple beam structure that has.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 2, have a cycloidal planetary gear speed reducer structural representation that output shaft is a simple beam structure for a kind of, described a kind of output shaft that has is that the cycloidal planetary gear speed reducer of simple beam structure is made up of body 1, input shaft 2, input end cap 3, cycloidal gear 4, pin wheel housing 5, pin tooth 6, output bearing pin 7, output gear 8, output shaft 9, output bearing 10, capacity eccentric bearing 11, baffle ring 12, step bearing 13 and stifle 14.
During work, power reaches cycloidal gear 4 by input shaft 1, cycloidal gear 4 is by pin tooth 6, power is reached output bearing pin 7, output bearing pin 7 drives output shaft 9 power is reached output gear 8, output gear 8 forms simple beam structure in the centre of two output bearings 10, makes output shaft can bear bigger radial load.
