Description
Technical Field
The utility model belongs to the technical field of mechanical transmission, and particularly relates to a repairable metal film type coupler.
Background
The marine large metal film type coupling is generally arranged between a main machine and a transmission shaft system and is used for compensating axial or radial deflection brought by the main machine or the shaft system after elastic installation, isolating vibration transmission from the main machine to the shaft system and transmitting power of the main machine to the shaft system. In general, a metal film type coupling for a large-sized transmission shafting has the characteristics of large size, heavy mass, large transmission power and the like, and is generally important transmission equipment of a large-sized ship shafting.
The large metal film type coupling compensates the shafting deflection capability, isolates the transmission capability of the main machine to shafting vibration and transmits the power capability of the main machine, and the elastic element-metal film (or metal film component) of the coupling is determined. Therefore, the performance of the metal diaphragm (or metal diaphragm assembly) in a large metal diaphragm type coupling directly determines the performance of the coupling. The metal diaphragm (or the metal diaphragm assembly) is subjected to rated torque, bending stress generated by axial deflection compensation and alternating bending stress generated by radial deflection compensation, alternating torsion stress generated by torque fluctuation of a main machine or a propeller and the like in the shafting operation process, and the stress condition is complex and bad. Fatigue fracture failure of the metal diaphragm may occur during long-term operation or under extreme conditions. At present, the elastic element of the metal film type coupler at home and abroad generally adopts an integral structure, and once the elastic element breaks under extremely severe working conditions or generates fatigue failure under long-term operation working conditions, the elastic element is basically difficult to be taken out of the cabin for maintenance. Therefore, it is necessary to develop a large metal film type coupling with repairable elastic elements that can accomplish the replacement of the elastic elements in a limited repair space.
At present, the research and the application of the large-scale repairable metal film type coupler are relatively few in China. For example, chinese patent CN211343784U discloses an elastic coupling device, in which the elastic element is made of rubber and has a small external dimension, and although the elastic element can be conveniently maintained and replaced, the torque transmission capability is not large in the same dimensional space. Chinese patent CN211145162U discloses a star-shaped elastic coupling, in which the elastic element is an internal star-shaped elastic element, and the compensation amount is limited because the elastic element is deformed by extrusion to compensate for the shafting offset. Chinese patent CN110513400a discloses a spring-type elastic coupling, which uses a metal spring as an elastic element to transmit torque and compensate shafting deformation, and dampens shafting vibration through friction damping of the spring, but the torque and compensation amount transmitted by the metal spring are still limited. Chinese patent CN206874693U discloses a double-diaphragm elastic coupling, which can effectively improve the working reliability of the device through the double-diaphragm structure, but does not provide much improvement for the maintainability of the device. Chinese patent CN211778621U discloses a diaphragm rubber block type coupling, which uses a combination of a metal diaphragm and a rubber block as an elastic element, so as to transmit a larger torque and compensate for a larger shafting offset, but the metal diaphragm is integral, and once the diaphragm fails, the diaphragm cannot be maintained and replaced in a limited space.
