The selection of the diaphragm coupling should be based on the machine type provided by the complete set or the host manufacturer and the shaft power under normal conditions, and should not be over-coded.
The elastic coupling relies on the elastic deformation of the elastic element to compensate the relative displacement of the two axes, and can also buffer and reduce vibration to avoid resonance.
The high-elastic coupling is formed by clamping a metal connecting piece and an elastic element under the pretension of a bolt group, and the elastic element is formed by vulcanizing and tightly combining rubber and a cord.
Diaphragm couplings are used in a variety of different host products, and the surrounding working environment is more complicated, such as temperature, humidity, water, steam, sand, alkali, salt water, radiation and other conditions.
There are three types of water pump couplings: claw-type elastic coupling, elastic pin coupling and diaphragm coupling.Accurate centering requirements for installation, shock mitigation, changing the natural vibration frequency of the shafting, and avoiding hazardous vibrations, etc.
The characteristic of the diaphragm coupling is a bit like a bellows coupling, in fact the way the coupling transmits torque is similar.
Water pump couplings are small in size, light in weight, simple in structure, easy to install, and inexpensive, and are often used in small power applications.
The whole machine has few parts, small size and light weight. The spring leaf designed as a trapezoidal cross-section and the trapezoidal tooth groove are particularly convenient and close, so that the assembly, disassembly and maintenance are simpler than ordinary couplings.
