Working environment of the coupling
Couplings are used with a variety of different host products, and the surrounding working environment is complex, including temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive media, salt water, radiation, etc. These are important factors to consider when selecting a coupling.
Analyze the balancing factors of the coupling
Couplings, due to various reasons, may have their mass center or principal inertia axis misaligned with their rotating axis. During operation, this will cause unbalanced centrifugal inertia force, centrifugal inertia moment, and dynamic deflection (vibration mode), a phenomenon known as rotor imbalance. This imbalance will inevitably cause vibration in the shaft system, affecting the normal operation and service life of the machine.
Maintenance and assembly of diaphragm couplings
A diaphragm coupling consists of several sets of diaphragms bolted alternately to the two halves of the coupling. Each set of diaphragms is made up of several stacked diaphragms. Diaphragms are divided into connecting rod type and different shapes of integral type.
Basic steps for coupling selection
Select a suitable coupling type based on factors such as the size of the transmitted load, the speed of the shaft rotation, and the installation accuracy of the two connected components, with reference to the characteristics of various couplings.
Development Trend of Drum-shaped Toothed Couplings
Drum-shaped tooth coupling is a new type of tooth coupling developed by digesting and absorbing foreign advanced technology on the basis of straight tooth gear coupling.
The selection of couplings depends primarily on the material; generally, there are three categories: hard aluminum alloy, engineering plastics, and steel.
