Abstract

The utility model discloses a star-shaped elastic coupling which is used for connecting a driving shaft and a driven shaft. The star-shaped elastic coupling comprises a first half coupling, a second half coupling and a star-shaped elastic element, wherein the first half coupling is connected with the driving shaft, the second half coupling is connected with the driven shaft, and the star-shaped elastic element is positioned between the first half coupling and the second half coupling; one end of the first half coupling and the second half coupling close to the star-shaped elastic element is respectively provided with a projecting tooth, and the star-shaped elastic element is arranged between the projecting tooth of the first half coupling and the projecting tooth of the second half coupling; and the star-shaped elastic element is a rubber elastic element. Since the elastic element is only subjected to pressure and not subjected to tension, the utility model has the advantages of long service life, simple use process, convenient machining operation and low cost.

Description

The star elastic coupling flexible coupling
Technical field
The utility model relates to a kind of coupling, relates in particular to a kind of star elastic coupling flexible coupling.
Background technique
Coupling makes its barycenter or principal inertia axis add shaft axis with it for various reasons and does not overlap; To produce the phenomenon of uneven centrifugal inertia force, centrifugal inertia idol power and dynamic deflection (vibration shape) in the running; This energy imbalance must cause the vibration of axle system, thereby influences the proper functioning and the working life of machine.
Multiple factors such as relative movement between the distortion that diaxon that coupling joins produces owing to foozle, alignment error, axle stand under load, pedestal distortion, bearing wear, temperature variation (heat expansion, shrinkage), the parts produce relative displacement.Generally speaking, the diaxon relative displacement is difficult to avoid, but the axle under the different working condition is the direction of displacement that transmission produces, promptly axially (x), radially (y), angle (a) and displacement amount is big or small different.Application area is restricted, so consumption seldom.
Summary of the invention
The purpose of the utility model not to receive pulling force with regard to being to provide a kind of elastic component only to be stressed in order addressing the above problem, to make star elastic coupling flexible coupling simple, that the life-span is long.
The utility model is realized above-mentioned purpose through following technological scheme:
The utility model is used to connect driving shaft and driven shaft; Comprise first half-coupling, second half-coupling and star elastic component; Said first half-coupling is connected with said driving shaft; Said second half-coupling is connected with said driven shaft, and said star elastic component is between said first half-coupling and second half-coupling.
Further, said first half-coupling and said second half-coupling are provided with protruding tooth near an end of said star elastic component, and said star elastic component places between the protruding tooth of protruding tooth and said second half-coupling of said first half-coupling.
Further, said star elastic component is a rubber parts.
The beneficial effect of the utility model is:
The utility model is because elastic component only is stressed and does not receive pulling force, and the life-span is longer, use simple, and easy to process, cost is lower.
Description of drawings
Fig. 1 is the partial sectional view of the utility model;
Fig. 2 is the A-A sectional view among Fig. 1.
Among the figure: 1-the first half-coupling, 2-rubber spider elastic component, 3-the second half-coupling, 4-protruding tooth.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As depicted in figs. 1 and 2; The utility model is used to connect driving shaft and driven shaft; Comprise that first half-coupling 1, second half-coupling 2 and star elastic component 3, the first half-couplings 1 are connected with an end of rubber spider elastic component 2, the other end of rubber spider elastic component 2 is connected with second half-coupling 3; All be shaped on protruding tooth 4 on first half-coupling 1 and second half-coupling 3; Rubber spider elastic component 2 is placed between the protruding tooth 4 of first half-coupling 1 and second half-coupling 3, and 2 of star elastic components are stressed and do not receive pulling force, the rubber spider elastic component 2 pressurizeds transmitting torque that contracts.
In conjunction with Fig. 2, the process of the utility model work is following:
1, first half-coupling 1 and second half-coupling 3 are provided with protruding tooth 4.
2, the rubber spider elastic component of processing with rubber material 2 is placed between first half-coupling 1 and second half-coupling 3.
3, an end of first half-coupling 1 and second half-coupling 3 is connected driving shaft (not shown) and driven shaft (not shown) respectively.
When 4, the driving shaft (not shown) was rotated, rubber spider elastic component 2 pressurizeds contractd and pass to the driven shaft (not shown), thereby realized being connected of driving shaft (not shown) and driven shaft (not shown).
The focusing on of the utility model provides a kind of first half-coupling and second half-coupling and coupling through the transmission of star elastic component pressurized of comprising; If only change size, shape or the structure of first coupling, second coupling or star elastic component, then all should be regarded as invading the right of the utility model.
