JMJ type double diaphragm coupling correct selection

Said JMJ type double diaphragm coupling this kind of transmission products, we must be in the process of selection is a headache, do not know how to correctly choose the coupling products. We don't need to panic, next Xiaobian to explain the relevant knowledge of the choice of the coupling transmission parts for you.

JMJ double diaphragm coupling its use characteristics are a bit like bellows coupling, in fact, the coupling transmission parts transfer torque in the same way. The diaphragm itself is thin, so it is relatively easy to bend when relative displacement loads are applied, and thus can withstand up to 1.5 degrees of deviation while producing a lower bearing load in the servo system. The JMJ double diaphragm coupling consists of at least one diaphragm and two bushings. The diaphragm is fastened to the bush with a pin without generally loosening or causing recoil between the diaphragm and the bush. Some manufacturers supply two diaphragms, others supply three diaphragms with one or two rigid elements in the middle, and the two sides are connected to the bushing.

The JMJ double diaphragm coupling looks delicate, but is more prone to damage if misused or improperly installed. So it is more important not to have deviation in the normal operation of the coupling transmission parts within the bearing range. The coupling drive is often used in servo systems, the diaphragm has better torque rigidity, but less than the bellows coupling.
