The diaphragm coupling consists of several groups of diaphragms (stainless steel sheets) that are connected to the two halves of the coupling by bolts alternately. Each group of diaphragms is formed by stacking several pieces. slice. 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.
