Abstract
A simple supporting beam structure for the speed reducer with cycloid pin gear features that its output shaft is supported at both ends instead of original one end. Its advantages are compact structure, uniform load, and high load-bearing power.
Description
A kind of simple beam structure of cycloidal planetary gear speed reducer, it is specially adapted in the cycloidal planetary gear speed reducer in the cycloidal-pin wheel transmission device.
Usually the mechanism that the output shaft in the cycloidal planetary gear speed reducer, bearing pin and cycloid wheel are formed calls W mechanism, transmission device in the prior art in the cycloidal planetary gear speed reducer, the supporting of its W mechanism output shaft is same end bearing, be cantilever structure, this structure causes axial dimension longer, therefore, transmission device can not bear bigger radial force, cause carrying little, and structure is not compact, the designing requirement of incompatibility supporting machinery.
The goal of the invention of the simple beam structure of W mechanism is in the cycloidal planetary gear speed reducer of the present invention: make this transmission device can bear bigger radial force, shorten the transmission device axial dimension simultaneously, to adapt to the designing requirement of supporting machinery, it is big to reach carrying, compact structure.
Technology implementation scheme of the present invention is that the supporting spacing increasing with output shaft improves the stress, particularly radial force state of output shaft, and the axial dimension of speed reduction gearing is shortened, and makes structure compact more, stress equalization.
For detailed explanation technology of the present invention constitutes, see also accompanying drawing and be described further as follows:
Fig. 1 is prior art cycloidal-pin wheel formula speed reducer transmission device W mechanism structure and stressed schematic representation;
Fig. 2 is the simple beam structure and the stressed schematic representation of W of the present invention mechanism.
See also Fig. 1, be this speed reducer transmission device W mechanism structure and stressed schematic representation of prior art, is by two bearings 11 by diagram behind the output shaft 1,12 be arranged on equal load plate 2 before, this structure forms same end bearing, the axial dimension of output shaft 1 is longer, its stress as shown in the figure, F is an axial force, after stressed, two fulcrum △ are arranged, because spacing is little, the power of the other end F ' of output shaft 1 is bigger, like this, the radial force of output shaft 1 is just relatively poor, and in order to increase its radial force situation, the present invention as shown in Figure 2, output shaft 1 shortens and preceding equal load plate 2 spacings, increase all load plates 3 of back, and bearing 12 is moved to the back all behind the load plate 3, we widen the supporting spacing of output shaft 1 like this, shorten the axial dimension of transmission device simultaneously, as shown in the figure, the supporting point △ spacing of its output shaft 1 widens, and the F power that acts on the output shaft 1 obtains equilibrium, power F ' obviously reduces, and improves.
In sum, the inventor is by to the widening of the output shaft supporting spacing in the cycloidal planetary gear speed reducer transmission device, the shortening of the axial dimension of its speed reduction gearing, and its stressed increase, and it is compact more to make it structure, adapts to the designing requirement of supporting machinery more.Thereby the inventor has reached purpose of the present invention, changes the shortcoming of the same end bearing existence of the output shaft in the prior art.
