Correct Selection Of Diaphragm Flexible Coupling

Correct Selection Of Diaphragm Flexible Coupling

1, the diaphragm flexible coupling at least consists of a diaphragm and two axle housing.Diaphragm is used pin fastening on the axle housing generally not loose or cause between the diaphragm and the shaft sleeve recoil.Some coupling manufacturers provide two diaphragm, also have provide three of the diaphragm, there are one or two rigid element, among both sides and even on the axle housing.
2, diaphragm flexible coupling this feature is a bit like bellows coupling, coupling torque is actually the way are similar.Diaphragm itself is very thin, so it is easy to bend when produce relative displacement load, so it can bear the deviation of up to 1.5 degrees, at the same time in the servo system is formed in the lower bearing load.
3, diaphragm flexible coupling is often used in servo system, has the very good torque stiffness of diaphragm, but less in the corrugated pipe couplings.
4, on the other hand, the diaphragm flexible coupling is very delicate, if in use misuse or not installed correctly, it is easy to damage.So ensure the deviation in the normal operation of coupling affordable is very necessary.
5, according to the diameter of axle adjustment models: preliminary selected bearing coupling dimensions, namely the axle hole diameter d and length of the shaft hole, L should meet the requirements of the Lord, driven end diameter of axle is according to the diameter of axle d adjustment of the specifications of the coupling.Master and slave side different diameter of axle is a normal phenomenon, when the same torque and rotational speed, master and slave side trunnion don’t phase at the same time, should press to choose the big diameter of axle coupling model.The new design of transmission system, should choose to conform to that stipulated in the GBT3852 seven shaft hole type, J1 type is recommended for the shaft hole pattern, in order to improve the versatility and interchangeability, shaft hole length according to provisions of bearing coupling product standards
