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.

How to align couplings

1) Fix the outboard foot on the motor side of the fixed lifting accessory coupling, and move the inboard foot until the eccentricity between the motor and pump centers is zero. To ensure that the motor does not move arbitrarily, after fixing the foot on one side of the motor, the other side should be supported by a set screw.

Universal joint lubrication method

The universal joint cross shaft needle roller bearings of a drive shaft should be lubricated with gear oil. However, it is generally found in automotive repair that the universal joint cross shaft needle roller bearings of a drive shaft are lubricated with calcium-based lubricating grease (commonly known as butter), which is actually an incorrect lubrication method, leading to premature damage of a large number of cross shaft needle roller bearings.
