What is a Diaphragm Coupling? Several groups of diaphragms (stainless steel sheets) are staggeredly connected with the two halves of the coupling with bolts. Each group of diaphragms is formed by stacking several pieces. The diaphragms are divided into connecting rod type and whole-piece type with different shapes. The diaphragm coupling compensates for the relative displacement of the two shafts connected by the elastic deformation of the diaphragm. It is a high-performance flexible coupling with strong metal elements. It does not need to be lubricated. It has a compact structure, high strength and long service life. , No rotation gap, not affected by temperature and oil pollution, it has the characteristics of acid resistance, alkali resistance and anti-corrosion, and is suitable for shafting transmission in high temperature, high speed and corrosive medium working conditions.
The diaphragm coupling can compensate for the axial, radial and
angular offsets between the main motor and the driven motor due to
manufacturing errors, installation errors, load-bearing deformation
and the influence of temperature rise changes. Diaphragm coupling
is a flexible coupling of metal elastic element. It relies on metal
coupling diaphragm to connect the main and slave motors to transmit
torque. It has the advantages of elastic vibration reduction, no
noise and no lubrication. Ideal products for couplings and general
couplings
