Description

Technical Field

[0002] Couplings are also called couplings. They are generally used to connect the driving shaft and driven shaft of different mechanisms to perform rotational motion, to transfer kinetic energy and torque. Different coupling holes and coupling lengths can be set or selected according to the size of the shaft to be connected. Couplings can also compensate for the offset between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, as well as mitigate impact and absorb vibration.

[0003] For example, an application with publication number CN205078639U discloses a diaphragm coupling, comprising a damping plate group, a base, a sleeve, a small washer, a high washer, a left half-shaft section, and a right half-shaft section; the damping plate group comprises a plurality of damping plates overlapping each other; the outside of the damping plate group is coated with a base; a plurality of through holes are radially arrayed between the damping plate group and the base, a sleeve is arranged in each through hole, and a bolt passes through the middle through hole of the sleeve; a small washer is close to one end of the sleeve, and a high washer is arranged at the other end, and a left half-shaft section and a right half-shaft section are close to the outside of the two washers; a plurality of through holes are correspondingly arranged on the left and right half-shaft sections, some large and some small, and are evenly spaced in annular shapes, and the large hole of the left half-shaft section corresponds to the small hole of the right half-shaft section, and vice versa; a high washer is placed in the large hole, and a nut is placed at the outer end of the small hole.

[0004] However, the diaphragm couplings in the application are all connected by bolts, and there is no buffering effect at the connection. After long-term use, the bolts are prone to breakage, causing damage to the equipment and affecting production efficiency. A diaphragm coupling with a buffering effect is now provided. Utility Model Content

During the high-speed operation and long-term use of the diaphragm coupling, when the bolts undergo plastic deformation or breakage, the diaphragm coupling will stop running, affecting the working efficiency. When the device is in use, the adsorption magnetic block connecting groove and the adsorption magnetic block connecting block are fitted together to disperse the overall stress of the diaphragm coupling, thereby increasing the service life of the diaphragm coupling and facilitating the installation of the diaphragm coupling by operators.

[0011] By adopting the above technical solution, the right half shaft section and the left half shaft section are installed and fixed as a whole.

[0012] In a preferred embodiment, a diaphragm is movably mounted on the surface of the first connecting bolt and the second connecting bolt.

[0013] By adopting the above technical solution, the diaphragm coupling belongs to a metal flexible coupling, which uses the diaphragm as a flexible element to transmit torque. Its main features are large torque transmission capacity, absorbing the misalignment of the unit by diaphragm deformation, and no relative movement between the parts. The diaphragm can ensure that the overall device is free of wear, noise, and vibration reduction. Long service life.

[0015] By adopting the above technical solution, the first clamping bolt can increase the clamping torque to prevent the shaft from slipping due to insufficient clamping force, thereby affecting the transmission accuracy. In addition, due to the large clamping torque, the transmission torque of the coupling is also increased.

[0016] In a preferred embodiment, a gasket is bonded to the surface of the connecting member.

[0017] By adopting the above technical solution, the relative friction of each component is reduced and the service life of the diaphragm coupling is increased.

[0018] In a preferred embodiment, through holes are formed on the surfaces of the right half shaft section and the left half shaft section.

[0019] By adopting the above technical solution, the production cost of materials can be reduced and the production rate can be improved without affecting the overall use of the diaphragm coupling.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In the present application, the commonly used diaphragm coupling only adopts one connection method of bolt fixing. During the high-speed operation and long-term use of the diaphragm coupling, when the bolts undergo plastic deformation or breakage, the diaphragm coupling will stop operating, affecting the working efficiency. When the present device is in use, the adsorption magnetic block connecting groove and the adsorption magnetic block connecting block are fitted together to disperse the overall stress of the diaphragm coupling, thereby increasing the service life of the diaphragm coupling and facilitating the installation of the diaphragm coupling by the operator.

Its main features are large torque transmission capacity, absorbing the misalignment of the unit by diaphragm deformation, and no relative movement between the parts. The diaphragm can ensure that the entire device is free of wear, noise, and vibration reduction. Long service life.

[0031] Example:

[0032] A diaphragm coupling comprises a connecting piece 1 and a right half-shaft joint 13, wherein an adsorption magnetic block connecting block 10 is fixedly mounted on the surface of the right half-shaft joint 13, an adsorption magnetic block connecting block 10 is movably mounted with an adsorption magnetic block connecting groove 16, a left half-shaft 15 is welded to the side of the adsorption magnetic block connecting groove 16, and the size of the adsorption magnetic block connecting groove 16 matches that of the adsorption magnetic block connecting block 10.

[0033] The commonly used diaphragm coupling only uses one connection method, which is bolt fixing. During the high-speed operation and long-term use of the diaphragm coupling, when the bolts undergo plastic deformation or breakage, the diaphragm coupling will stop operating, affecting the working efficiency. When the device is in use, the adsorption magnetic block connecting groove 16 is fitted with the adsorption magnetic block connecting block 10 to disperse the overall stress of the diaphragm coupling, thereby increasing the service life of the diaphragm coupling and facilitating the installation of the diaphragm coupling by the operator.

[0034] The surface of the right half-shaft 13 is provided with a receiving hole 7, and a threaded hole 6 is provided adjacent to the receiving hole 7. A second connecting bolt 8 is movably installed on the surface of the receiving hole 7, and a first connecting bolt 5 is movably installed on the surface of the threaded hole 6. The overall reinforcement force of the diaphragm coupling is strengthened, the operation is simple, and the installation is convenient. The receiving hole 7 and the threaded hole 6 have good matching, which is convenient for the connection between the right half-shaft 13 and the left half-shaft 15, and no dispersion and falling occurs under the high-speed operation of the diaphragm coupling.

[0035] The end of the second connecting bolt 8 is movably provided with a second receiving hole 17, and the end of the first connecting bolt 5 is movably provided with a second threaded hole 14. The right half-shaft 13 and the left half-shaft 15 are integrally installed and fixed.

[0036] The surface of the first connecting bolt 5 and the second connecting bolt 8 is movably mounted with a diaphragm 9. The diaphragm coupling is a metal flexible coupling, which uses the diaphragm 9 as a flexible element to transmit torque. Its main features are large torque transmission capacity, and the diaphragm 9 deforms to absorb the misalignment of the unit. There is no relative movement between the parts. The diaphragm can ensure that the overall device is free of wear, noise, and has a long vibration reduction life.

[0037] The surface of the connector 1 is provided with a mounting hole 4, and the surface of the mounting hole 4 is movably plugged with a first clamping bolt 3. The first clamping bolt 3 can increase the clamping torque to prevent the shaft from slipping due to insufficient clamping force, which affects the transmission accuracy, and due to the large clamping torque, the transmission torque of the coupling is also increased.

[0038] The surface of the connector 1 is bonded with a gasket 2, which reduces the relative friction between the components and increases the service life of the diaphragm coupling.

[0039] The surfaces of the right half shaft section 13 and the left half shaft section 15 are provided with through holes 11. Without affecting the overall use of the diaphragm coupling, the production cost of the material is reduced and the production rate is improved.

[0040] The implementation principle of a diaphragm coupling embodiment of the present application is:

[0041] The commonly used diaphragm coupling only uses one connection method, which is bolt fixing. During the high-speed operation and long-term use of the diaphragm coupling, when the bolts undergo plastic deformation or breakage, the diaphragm coupling will stop operating, affecting the working efficiency. When the device is in use, the adsorption magnetic block connecting groove 16 is fitted with the adsorption magnetic block connecting block 10 to disperse the overall stress of the diaphragm coupling, thereby increasing the service life of the diaphragm coupling and facilitating the installation of the diaphragm coupling by the operator.

[0042] The diaphragm coupling is a metal flexible coupling that uses the diaphragm 9 as a flexible element to transmit torque. Its main feature is that it has a large torque transmission capacity. The diaphragm 9 deforms to absorb the misalignment of the unit. There is no relative movement between the parts. The diaphragm can ensure that the entire device is wear-free, noise-free, and has a long vibration reduction life. The first clamping bolt 3 can increase the clamping torque to prevent the shaft from slipping due to insufficient clamping force, affecting the transmission accuracy, and due to the large clamping torque, the transmission torque of the coupling is also increased.
