Flexible plate couplings

Structure of flexible plate couplings

Flexible plate coupling absorbs shaft misalignment through plate bending. There are two types of structure; they are single plate type and double plates type. They must be chosen correctly in consideration of shaft misalignment conditions to avoid unforeseen failure of rotating system.

Plate material characteristics

Polyimide

Polyimide is a super engineering plastic that is highly heat resistant and extremely chemically stable. It also has a high tensile strength and elasticity, and its outstanding flexibility enables it to be used for the flexible plates of couplings, enabling flexibilities to be achieved that are not possible using metals.

Carbon FRP (fiber reinforced plastic)

This material is made by solidifying textiles made of carbon fibers by means of resin impregnation. It is the strongest and most elastic of commercially available materials, and has excellent mechanical characteristics, such as low creep and high fatigue strength (which is 3 to 7 times greater than that of aluminum alloys). This material offers a well-balanced set of characteristics for the flexible plates of couplings-high torsional rigidity and transmission torque, without fatigue damage due to bending caused by parallel and angular misalignments.

Stainless steel

This material utilizes thin stainless steel plates with added spring characteristics provided by heat treatment. This material has the highest tensile strength of the three materials, so it offers high rigidity and high torque for the flexible plates of couplings. On the other hand, it offers the least tolerance for axial mismatching; particularly parallel misalignment, so it must be assembled carefully.
