What are the differences in structural characteristics and applications between diaphragm couplings and plum couplings?

Plum couplings and diaphragm couplings are frequently used in automation equipment. In the actual use of mechanical transmission, can you understand their structural differences and characteristics? Customers often ask us: diaphragm couplings and plum couplings What are the differences in the structural characteristics and applications of the coupling? Let me explain to you today:

First of all, we know that the diaphragm coupling is flexible, and the plum coupling is elastic. From the daily response, the torque transmitted by the diaphragm coupling is larger than that of the plum coupling. Moreover, the use of diaphragm couplings is more reliable. Diaphragm couplings are often used when large torque transmission is required.

The diaphragm coupling can compensate for the axial, radial and angular deviations between the active machine and the driven machine due to manufacturing errors, installation errors, load-bearing deformation, and the effects of temperature rise changes. The diaphragm coupling is a flexible coupling with a metal elastic element, which relies on the metal coupling diaphragm to connect the main and driven machines to transmit torque. It has the advantages of elastic vibration reduction, no noise, and no lubrication.

The plum blossom coupling is simple in structure, does not require lubrication, is convenient for maintenance, easy for inspection, maintenance-free, and can run continuously for a long time. High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and are safe and reliable. The work is stable and reliable, with good vibration damping, buffering and electrical insulation properties. It has large axial, radial and angular compensation capabilities. The structure is simple, the radial size is small, the weight is light, and the moment of inertia is small. It is suitable for medium and high speed occasions.

Second: The material of the diaphragm coupling is different from that of the plum coupling

The plum coupling is composed of polyurethane material plastic as the elastic element and the main body of the two-half coupling. The main body is the imported secret recipe aluminum profile aluminum key. The upper polyurethane material plastic electronic components are configured with a unique secret recipe and have high wear resistance The defensive ability is good, and the ductility is strong, and the quality is stable and durable (compared before and after the good or bad). The plum-shaped body has six petals and eight petals, which are customized according to customer requirements. Fixed will not change the method. .

The diaphragm coupling is made up of two sets of pulsation dampers with anchor screws (different models and specifications are used according to different diameters) and the two sections of the coupling are closely connected, and 1 set of pulsation dampers is composed of several pieces. The pulsation damper is divided into ring or triangle.

Third: Diaphragm coupling and plum blossom coupling have different characteristics

The diaphragm coupling relies on the plastic deformation of the pulse damper to compensate for the universal deviation of the connected two shafts. It is a flexible coupling with a composite elastic element of this characteristic. It does not need to be lubricated, and has a compact structure and compressive strength. High, long service life, no rotation gap, no damage from temperature and oil stains, acid resistance, alkali resistance, and corrosion resistance.It can be driven by shaft gears with high temperature, high speed, and topography loaded with corrosive compounds.

The plum blossom coupling is simple in structure, does not need to be lubricated, saves time and effort in overhaul, is conducive to inspection, free of maintenance, and sustainable habitual operation. The elastic element of super wear-resistant polyurethane material is resistant to wear and corrosion, with large bearing capacity, long service life, and reliable. The work is stable and reliable, with high-quality shock absorption, file cache and electrical equipment volume resistivity. Possess great professional skills in radial, axial and angular compensation. The structure is simple, the axial model specification is small, lighter, the moment of inertia is small, and it can be used in the middle and high speed places.

Fourth: Diaphragm coupling and plum blossom coupling have different application ranges

Torx couplings are widely used in spindle servo motors, and diaphragm couplings are used in transmission servo motors.
