Abstract
The invention relates to a diaphragm coupling with low additional bending moment. The diaphragm coupling comprises a middle isolating shaft, diaphragms, a mounting disc and switching discs, wherein the diaphragms are symmetrically arranged at the two ends of the middle isolating shaft; and the diaphragm coupling is characterized in that: the diaphragms and the mounting disc are in an integrated structure. The mounting disc is inserted into the switching discs; the diaphragms are positioned with the switching discs by using convex concave seams and are connected with the switching discs through first bolt components to transfer torsion moment; and the switching discs are positioned with the middle isolating shaft by using positioning rings and are connected with the middle isolating shaft through second bolt components to transfer torsion moment. One end of each switching disc is a first connecting end which is connected with the diaphragm, and the other end of the switching disc is a second connecting end which is connected with the middle isolating shaft; and a disc body of the switching disc is arranged between the first connecting end and the second connecting end. The profile of the disc body is right-angled or obtuse. In the diaphragm coupling, the diaphragms and the mounting disc are designed to be in the integrated structure; the diaphragm coupling has a simple structure and light weight; and the weight and the additional bending moment of the diaphragm coupling are effectively reduced.
Description
Technical field
The present invention relates to a kind of be used for the connecting coupling that master and slave motivation makes its synchronous rotation, especially a kind of low additional bending moment diaphragm coupling.
Background technique
In the domestic existing diaphragm coupling, membranous disc and mounting disc are separate part, and mounting disc is a normal mounting.Existing diaphragm coupling weight is big, additional bending moment is big, can't satisfy the usage requirement of high speed, high power transmission field.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the existing technology, a kind of low additional bending moment diaphragm coupling simple, in light weight, that additional bending moment is low, rotating speed is high that combines is provided, in transmitting torque, can compensate radially, angle and axially misaligning.
According to technological scheme provided by the invention, a kind of low additional bending moment diaphragm coupling, membranous disc, mounting disc and the transfer panel at separated axis two ends in the middle of separated axis, symmetry are installed in the middle of comprising, characteristic is: said membranous disc and mounting disc are integral structure.
Said mounting disc is inserted in the transfer panel, and said membranous disc utilizes convex-concave seam and transfer panel location, and connects transmitting torque through first bolt assembly, and said transfer panel utilizes positioning ring and middle separated axis location, and connects transmitting torque through second bolt assembly.
One end of said transfer panel is first connecting end that is connected with membranous disc, and the other end is second connecting end that is connected with middle separated axis, is the disk body of transfer panel between first connecting end and second connecting end.Rectangular shape of the profile of said disk body or obtuse angle shape.
The root of said membranous disc profile is connected with mounting disc, circular arc transition between the root of membranous disc profile and mounting disc, and form the circular arc depression at the root of membranous disc profile and the joint of mounting disc.
The top of said membranous disc profile is the membranous disc flange that is connected with transfer panel, and the lower end of membranous disc flange forms round-corner transition in the both sides of membranous disc.
The membranous disc flange at said membranous disc profile top utilizes convex-concave seam and transfer panel location.
Compared with present technology the present invention has the following advantages:
(1), membranous disc and mounting disc be designed to integrative-structure, and adopts stainless steel material, and be simple in structure, in light weight, corrosion-resistant;
(2), when membranous disc is installed, penetrate transfer panel, effectively reduced the weight and the additional bending moment of diaphragm coupling, having anti-chikung can;
(3), membranous disc profile root is designed to the concave structure that two fillets link to each other, and avoided the axial ratio hole big, the membranous disc umbrella distortion that causes during the interference assembling, two sides, membranous disc profile top all is designed to the round-corner transition structure, has effectively reduced membranous disc profile stress and has concentrated;
(4), compared with prior art, the present invention is simple in structure, in light weight, additional bending moment is low, high speed capability is strong.
