The correct choice of diaphragm coupling

Diaphragm coupling can compensate the axial, radial and angular deviations caused by manufacturing errors, installation errors, load-bearing deformation, and the effects of temperature rise between the driving machine and the driven machine. It belongs to the flexibility of metal elastic elements. The sexual coupling, which relies on the metal coupling diaphragm to connect the main and the driven motor to transmit torque, has the advantages of elastic vibration damping, no noise, and no need for lubrication. It is a substitute for gear couplings and general couplings today. Ideal product.Maintenance is required after installation. Two dial indicators are set on the end face and outer circle of the diaphragm coupling. When the shaft is turned by turning, check the full runout of the diaphragm coupling including end runout and radial runout. Numerical value to determine the straightness and coaxiality of the coupling and the shaft.Different speeds and different types of couplings have different requirements for runout. After the coupling is installed on the shaft, the deviation of the full runout of the coupling is within the tolerance range required by the planning. This is a diaphragm coupling One of the equipment skill requirements.After a period of use, each maintenance needs to check whether the beating value is still within the range.

Diaphragm couplingThe right choice: 　　

1. The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and others provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve. 　

2. The characteristic of diaphragm coupling is a bit like a bellows coupling. In fact, the way the coupling transmits torque is similar.The diaphragm itself is very thin, so it is easy to bend when the relative displacement load is generated, so it can withstand up to 1.5 degrees of deviation, while generating a lower bearing load in the servo system. 　

3. Diaphragm couplings are often used in servo systems. Diaphragms have good torque rigidity, but are slightly inferior to bellows couplings. 

4. On the other hand, the diaphragm coupling is very delicate, and it is easy to be damaged if it is misused or not installed correctly during use.

The diaphragm coupling is composed of several groups of diaphragms that are alternately connected to the two halves of the diaphragm coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rods and different shapes of whole pieces. The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the two shafts connected. It is a high-performance flexible coupling with strong metal components. It does not require lubrication, has a compact structure and has a long service life. Long, no rotating gap, not affected by temperature and oil pollution, acid and alkali resistance, suitable for high temperature, high speed, and corrosive medium shafting transmission environment, so what are the functions of the diaphragm coupling? Now let the staff of the diaphragm coupling manufacturer explain it to you, I hope it can be helpful to you.

The diaphragm coupling can compensate for the axial, radial and angular deviations between the driving machine and the driven machine due to manufacturing errors, installation errors, load-bearing deformations, and the effects of temperature rise changes. It is a flexible metal element. The sexual coupling, which relies on the metal coupling diaphragm to connect the main and the driven motor to transmit torque, has the advantages of elastic vibration reduction, no noise, and no need for lubrication. It is a substitute for gear couplings and general couplings today. Ideal product.
