Abstract
The utility model relates to an internal tooth-shaped elastic coupling, which comprises a driving axle housing, a driven axle housing and an elastic sleeve, wherein the middle part of the inner wall of the elastic sleeve is provided with a bulge, the inner walls of the elastic sleeve above and under the bulge are both provided with internal teeth, the outer walls of the driving axle housing and the driven axle housing are provided with external teeth matched with the internal teeth, and the driving axle housing and the elastic sleeve as well as the elastic sleeve and the driven axle housing are respectively plugged to form an integral body via the external teeth and the internal teeth. The utility model has the advantages that the coupling only consists of the elastic sleeve, the driving axle housing and the driven axle housing, thereby having simple structure and low cost and being easy to manufacture; internal tooth-shaped connection is adopted to allow larger axial, radial and angular displacement, and the elastic coupling is convenient to install and has low noise, small rotation power loss and long service life.
Description
Technical field
The utility model relates to a kind of internal tooth form elastic coupling flexible coupling.
Background technique
Present domestic employed coupling, as rigid coupling, flexible coupling etc., general do not allow bigger axially, radially or angular displacement. (application number is 922219036 to Chinese utility model patent, 87206169) two kinds of gear couplings are disclosed, but they all adopt two half-couplings, though technical order can reach requirement, structure is very complicated, technological requirement is very high, and cost is also high.
The model utility content
The purpose of this utility model provides a kind of internal tooth form elastic coupling flexible coupling, and structure is very simple, cost is low and permission is bigger axial displacement, radial displacement and angular displacement.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of internal tooth form elastic coupling flexible coupling, comprise driving axle housing, driven axle sleeve and resilient sleeve, the middle part of described resilient sleeve inwall is provided with projection, be equipped with internal tooth on the above and below resilient sleeve inwall of projection, the outer wall of described driving axle housing and driven axle sleeve is provided with the external tooth that matches with internal tooth, between described driving axle housing and the resilient sleeve and between resilient sleeve and the driven axle sleeve all the mutual grafting by external tooth and internal tooth form one.
The beneficial effects of the utility model are: coupling only is made of resilient sleeve, driving axle housing and driven axle sleeve, and structure is very simple, makes easily, and cost is low; The employing internal tooth form connects, can allow bigger axially, radially and angular displacement, and easy for installation, noise is low, the rotative power loss is little, long service life.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described a kind of internal tooth form elastic coupling flexible coupling of the utility model embodiment.
Among the figure:
1, driving axle housing; 2, driven axle sleeve; 3, resilient sleeve; 4, projection; 5, internal tooth; 6, external tooth.
Embodiment
As shown in Figure 1, the described a kind of internal tooth form elastic coupling flexible coupling of the utility model embodiment, comprise driving axle housing 1, driven axle sleeve 2 and resilient sleeve 3, the middle part of described resilient sleeve 3 inwalls is provided with projection 4, be equipped with internal tooth 5 on the above and below resilient sleeve inwall of projection 4, the outer wall of described driving axle housing 1 and driven axle sleeve 2 is provided with the external tooth 6 that matches with internal tooth, between described driving axle housing 1 and the resilient sleeve 3 and between resilient sleeve 3 and the driven axle sleeve 2 all the mutual grafting by external tooth 6 and internal tooth 5 form one, the effect of projection 4 is spacing to driven axle sleeve and driving axle housing.
Coupling only is made of resilient sleeve 3, driving axle housing 1 and driven axle sleeve 2, and structure is very simple, makes easily, and cost is low; The employing internal tooth form connects, can allow bigger axially, radially and angular displacement, and easy for installation, noise is low, the rotative power loss is little, long service life.
