Particularly, the annular elastic diaphragm adopts an annular convex structure, the effect is more remarkable, and the specific principle is described in detail in the following embodiments.
To further illustrate the technical solution of the present invention, the following specific examples are provided with reference to fig. 1 to 8.
Example 1
In the present embodiment, a coupling is provided, as shown in fig. 1-4, which is a circular ring structure comprising, in the radial direction, an inner ring 101, an outer ring 102 and a pre-stretched annular elastic membrane 103; a pre-stretched annular elastomeric membrane 103 is integrally connected between the outer ring 102 and the inner ring 101 so that the inner ring 101 is deflectable relative to the outer ring 102; the inner ring 101, the outer ring 102 and the pre-stretched annular elastic membrane 103 are coaxial; the prestretched annular elastic membrane 103 is provided with an annular convex structure protruding out of the annular surface of the outer ring 102 and the annular surface of the inner ring 101; when inner ring 101 deflects relative to outer ring 102, the pre-stretched annular elastomeric membrane 103 deforms to accommodate the change in the relative deflection of inner ring 101 and outer ring 102.
In a preferred embodiment of this embodiment, the annular elastic diaphragm 103 is a convex structure with one convex side and the other concave side, the outer periphery of the inner ring 101 is tangent to the inner periphery of the annular elastic diaphragm 103, and the inner periphery of the outer ring 102 is tangent to the outer periphery of the annular elastic diaphragm 103. The outer periphery of the inner ring 101 is connected with the inner periphery of the prestretched annular elastic membrane 103 to form an integral structure; the inner peripheral edge of the outer ring 102 is connected with the outer peripheral edge of the annular elastic diaphragm 103 to form an integral structure. Preferably, the concave surface and the convex surface of the annular convex structure are annular corrugated bulges formed by arc surfaces, spline surfaces or cosine curved surface structures. When the convex structure is constructed by a circular arc surface, it can be formed by three sections of tangent circular arc structures. Preferably, the inner ring, the outer ring and the pre-stretched annular elastic membrane have equal thickness, and both sides of the inner ring and the outer ring are on the same plane.
Specifically, the narrower the width of the inner ring and the outer ring is, the better the width is, in order to satisfy the installation size of the hold-down bolt.
The annular elastic membrane in the embodiment adopts a pre-stretching structure, so that under the condition that the inner ring and the outer ring are all fixed, a larger angle difference can be allowed, and radial rigidity can be provided.
Taking a nutation reducer as an example, as shown in fig. 5, an inner ring 101 is fixedly connected with an output shaft of the nutation reducer, an outer ring 102 is fixedly connected with a nutation gear 500 in the nutation reducer, the inner ring 101 and the output shaft 600 are coaxially arranged, the outer ring 102 and the nutation gear 500 in the nutation reducer are coaxially arranged, an included angle between an axis of the nutation gear 500 and an axis of the output shaft is greater than 0 °, when a nutation gear 400 on the nutation reducer performs nutation motion on a non-nutation gear 700, an axis of the outer ring 102 is intersected with an axis of the inner ring 101, and the outer ring 102 partially straightens an annular convex structure along with the nutation motion of the nutation gear. The annular elastic diaphragm 103 is arranged into an annular convex structure and is acted by the force of the nutation gear 400, deflection of a certain angle is generated between the axis of the inner ring 101 and the axis of the outer ring 102, the axes are intersected, and torsion does not occur in the circumferential direction, so that the transmission precision is high, meanwhile, the deflection between the axis of the inner ring 101 and the axis of the outer ring 102 is the direction of bearing radial force, the direction of the bearing radial force of the annular convex structure is always kept in a straight state, the bending stress and the strain generated when the annular convex structure is straightened can be almost ignored, the radial rigidity of the annular elastic diaphragm 103 can be improved, and the safety coefficient of elastic instability of the annular elastic diaphragm can be improved. Preferably, the annular elastic membrane 103 may be pre-stretched and formed with a predetermined deformation amount to adapt to the change of the rotation angle of the output shaft of the transmission mechanism, and the inner ring 101, the outer ring 102 and the annular elastic membrane 103 are integrally formed.

The torque is transmitted through the reamed bolt holes, and meanwhile, the mounting and positioning accuracy is guaranteed in the mounting process.
Preferably, the annular elastic diaphragm has a thickness S, and the difference between the inner diameter of the outer ring and the outer diameter of the inner ring is P, wherein S, P satisfies: s is less than or equal to 2 percent of P, so that overlarge bending stress of the annular elastic membrane is avoided.
Preferably, when the inner ring and the outer ring deflect, the axis of the inner ring is intersected with the axis of the outer ring, and the included angle between the axis of the inner ring and the axis of the outer ring is less than or equal to 6 degrees, so that the radial rigidity of the coupling can be ensured, and the phenomenon that the bending part of the annular elastic diaphragm has too small curvature radius and can generate larger bending stress when being straightened is avoided.

The second hinge holes 1021 on the coupling 100 on both sides of the ring sleeve 200 are in clearance fit with the hinge bolts to realize radial positioning. In this embodiment, the inner rings 101 of the couplers 100 on both sides of the ring 200 may be fixedly connected to the ring 200 by the hinge bolts 800, that is, the hinge bolts sequentially pass through the inner ring 101 of the coupler 100 on one side, the ring 200 and the inner ring 101 of the coupler 100 on the other side, and the other ends of the hinge bolts are fastened by nuts.
