Jiangsu JMⅡ type non-counterbore basic diaphragm coupling

JMⅡ basic type without counterboreDiaphragm couplingIt is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is made up of several stacked ones. The diaphragms are divided into connecting rod type and whole piece type of different shapes.Its elastic deformation compensates for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, has a long service life, has no rotation gap, and is not subject to temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance, and anti-aging.

The JM Ⅱ type non-counterbore basic diaphragm coupling compensates the relative displacement of the two shafts connected by the elastic deformation of the diaphragm. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication and has a compact structure. , Long service life, no rotation gap, not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance, and hydration resistance.

Compared with the basic diaphragm coupling without counterbore, JMⅡ has no relative sliding, does not require lubrication, sealing, noise, basically does not require maintenance, and is more convenient to manufacture. It can partially replace gear couplings.Diaphragm couplings are widely used in the industrially developed industry. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.The diaphragm coupling has several groups of diaphragms (stainless steel thin plates) that are staggered and connected with the two halves of the coupling with bolts. Each group of diaphragms is composed of a plurality of stacks, and the diaphragms are divided into connecting rods and different shapes of whole pieces formula.For the characteristic values ​​of the axial vibration of the diaphragm coupling under various conditions, theoretically, an estimation formula for the axial stiffness is derived, and the natural frequency obtained by the formula is consistent with the experiment.
