Abstract

The utility model discloses a round head backing sheet fixed knot of diaphragm coupling constructs. The fixing sleeve of the diaphragm group plays a role in fixing the diaphragm group and is an important component for connecting the diaphragm group and the half coupling. Because the contact position of the fixed sleeve and the diaphragm of the existing structure is of a right-angle structure, the diaphragm deforms greatly at the right-angle position of the fixed sleeve under the action of additional displacement, and fatigue damage is easily caused. In order to solve the problems, a round-head supporting sheet fixing structure is designed, and the local deformation of the diaphragm near the fixing sleeve is reduced by utilizing the arc angle transition of the round-head supporting sheet and the large elastic deformation characteristic of the round-head supporting sheet, so that the service life of the diaphragm coupling is greatly prolonged.

Description

Round head support sheet fixing structure of diaphragm coupling
Technical Field
The utility model relates to a mechanical transmission's shaft coupling is motion, power transmission's draw bail between prime mover (like motor, internal-combustion engine etc.) and the working machine (like pump, speed reducer etc.), belongs to mechanical transmission technical field.
Background
The coupling is widely used in rotary machines, and includes a rigid coupling, an elastic coupling, and the like. The diaphragm coupling is a novel coupling, has the advantages of transmitting larger torque, allowing larger displacement error, allowing high-speed rotation, relaxing impact vibration, generally not needing lubrication, being convenient for installation and maintenance and the like, is widely applied to industries such as national defense, shipbuilding, aviation, petrochemical industry, vehicles, machinery and the like, and can replace coupling devices such as gear couplings, elastic sleeve pin couplings and the like. However, since the diaphragm assembly is subject to additional axial, radial, and angular displacements, the diaphragm assembly is susceptible to fatigue failure under the additional displacements. One of the reasons for causing damage to the diaphragm assembly is that under the action of additional displacement, the local deformation of the fixed position of the diaphragm assembly is too large, which is likely to cause fatigue damage, so that it is necessary to invent a diaphragm assembly fixing structure with a more reasonable structure.
Disclosure of Invention
The utility model provides a solve above technical problem and provide a diaphragm coupling's button head backing sheet fixed knot constructs with following structure, it comprises fixed cover 1 of diaphragm group right angle, diaphragm group 2, fixed cover right angle clamping ring 3 of diaphragm group, excircle head backup pad 4, and its characteristics are, and diaphragm group 2, fixed cover right angle clamping ring 3 of diaphragm group, excircle head backup pad 4 are installed on fixed cover 1 of diaphragm group right angle. In the fixed cover 1 axial direction of diaphragm group right angle, respectively set up 1 excircle head backup pad 4 in the outside of diaphragm group 2, set up fixed cover right angle clamping ring 3 of diaphragm group in the outside of setting up the outer button head backup pad 4 on right side.
The better implementation mode of the technical scheme is that the round-head support sheet fixing structure of the diaphragm coupler is beneficial to reducing the local overlarge deformation of the diaphragm group at the position of the fixed position, so that the possibility of fatigue damage of the diaphragm group is reduced, and the service life of the diaphragm coupler is greatly prolonged.

Detailed Description
The embodiments of the present invention are given below in conjunction with the accompanying drawings for further explaining the technical solutions.
Example 1, refer to fig. 1, fig. 2, fig. 3, fig. 4. The round-head support sheet fixing structure of the diaphragm coupler is characterized in that the diaphragm set 2, the diaphragm set fixed sleeve right-angle compression ring 3 and the excircle head support plate 4 are installed on the diaphragm set right-angle fixed sleeve 1. In the fixed cover 1 axial direction of diaphragm group right angle, respectively set up 1 excircle head backup pad 4 in the outside of diaphragm group 2, set up fixed cover right angle clamping ring 3 of diaphragm group in the outside of setting up the outer button head backup pad 4 on right side.
The conventional fixing sleeve structure is shown in fig. 1, and is at a right angle at 1-1 and 3-1, so that under the action of additional displacement, local deformation of the diaphragm at the position is larger, larger local stress is generated, and fatigue failure of the diaphragm is more easily caused.
Because there is the transition circular arc in the head department of excircle head backup pad 4, consequently, under the effect of same additional displacement, can greatly reduced at this local diaphragm local deformation, simultaneously, because outer button head backup pad 4 itself has certain elastic deformation ability, can compensate the deformation of diaphragm to reduce the fatigue failure degree of diaphragm.
