What are the characteristics of the connecting device of the diaphragm coupling?

Each group of diaphragms of the diaphragm coupling is formed by stacking several pieces, and the diaphragms are divided into two types: the connecting rod type and the whole-piece type with different shapes. The diaphragm coupling is made up of several groups of diaphragms that are staggered and connected to the two halves of the coupling with bolts. What are the characteristics of the linking device used in the diaphragm coupling?

Compared with the gear coupling, the diaphragm coupling has no relative sliding, does not need lubrication, sealing, no noise, basically no maintenance, is more convenient to manufacture, and can replace part of the gear coupling. Diaphragm couplings are widely used couplings in developed countries in the world. In practical applications, the intermediate shaft type is generally used to improve the offset compensation performance of the two axes.

Couplings mainly include metal diaphragm couplings, which make the diaphragm couplings have the advantages of light quality, reliable operation and convenient maintenance. New couplings such as serpentine spring coupling, hyperboloid tooth coupling, elastic coupling, etc. For example: the metal diaphragm coupling uses the high anti-shock characteristics of the metal diaphragm material.

Dotted with axial positioning. Taper sleeve and taper interference fit are used in the connection of pulley and shaft, the connection between sprocket and shaft, the connection between gear and shaft, etc., which greatly improves the production and disassembly. Through the locking of the screw, the expansion-tightening sleeve is a keyless adjoining device first used in Germany in the 1980s, which is easy to assemble and disassemble, does not require high shaft, hole processing and matching, and has overload concerns. work. It makes the transmission of your machine more stable, with good safety, and will not cause any mechanical damage to the shaft and the hub.
