Characteristics of flexible coupling:

1, plum shaped elastic parts generally use polyester polyurethane (hardness code a), or cast nylon (hardness code b), the former carrying capacity is lower than the latter. The half coupling and flange connection material is 45 steel or ZG70-500, in the chemical industry, in order to commonly use this phenolic resin to make half couplings.

2, plum elastic coupling torsional elasticity, shock absorption, maintenance-free, compact design, low inertia.

3, plum elastic coupling simple structure, fewer parts, small radial size, no lubrication; The elastic element has high load bearing capacity. Except for double-flanged spunx coupling, when changing the spunx flexible part of the wearing part, it is necessary to move the half coupling axially. This coupling has the ability to compensate for the relative deviation of the two axes.

4. The cross section of the coupling valve is usually circular, which can improve the uniformity of the distribution of the load on the working surface and transfer a larger torque, but the elasticity is slightly reduced. It can also be made into rectangles or segments. When the coupling is working, the quince valve is squeezed, and only half of the quince valve bears the work.

5, plum elastic coupling has two structural forms of casting material and steel material. Steel material is suitable for high-load drive units, such as rolling mills, lifts, splined shaft bushings, etc. Torque range: 5Nm--35000Nm

Diaphragm coupling material:

The diaphragm in the middle of the diaphragm coupling is made of high-grade stainless steel (AISI-301), which can not only diaphragm, life, labor and other characteristics, but also can be applied to most working conditions. At the same time, the surface of the diaphragm is covered with a low friction coefficient coating to reduce friction and improve its resistance to contact wear.

The diaphragm coupling adopts a 6-hole, 8-hole or 10-hole diaphragm group, and with the increase of the number of holes, the coupling can transmit higher torque and stronger rigidity, but the corresponding displacement deviation can be accommodated smaller.
