Coupling diaphragm

The diaphragm of the coupling consists of several groups of diaphragms (stainless steel thin plates) which are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rods and different shapes. Sliced.

Product introduction

Diaphragm coupling靠膜片的弹性变形来补偿所联两轴的相对位移，是一种高性能的金属强元件挠性联轴器，不用润油，结构较紧凑，强度高，使用寿命长，无旋转间隙，不受温度和油污影响，具有耐酸、耐碱的特点，适用于高温、高速、有腐蚀介质工况环境的轴系传动

product structure

The coupling diaphragm consists 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 some provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.The difference between the single diaphragm coupling and the double diaphragm coupling is the ability to handle various deviations. In view of the complex bending of the diaphragm, the single diaphragm coupling is not suitable for eccentricity.The double diaphragm coupling can bend in different directions at the same time to compensate for eccentricity.

Features

The characteristic of the coupling diaphragm 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.Diaphragm couplings are often used in servo systems. Diaphragms have good torque rigidity, but are slightly inferior to bellows couplings.On the other hand, the diaphragm coupling is very delicate and can be easily damaged if it is misused in use or not installed correctly.Therefore, it is very important to ensure that the deviation is within the tolerance range of the normal operation of the coupling.Choosing the right coupling is a key step to make good use of the coupling. You have to consider what type of coupling to choose in the design stage.

Application range

Widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, Aviation (helicopters), naval high-speed power transmission systems, steam turbines, piston-type power mechanical transmission systems, crawler vehicles, and high-speed, high-power mechanical transmission systems of generator sets are commonly used in high-speed transmission shaft systems after dynamic balance .
