江苏Four-hole coupling diaphragm

The four-hole coupling diaphragm has high mechanical strength, large carrying capacity, light weight, small structure size, high transmission efficiency and transmission accuracy, good performance, convenient assembly and disassembly, and has no relative sliding, does not need lubrication, and has a long service life. , No noise, acid and alkali resistance, etc., can be used in high temperature, low temperature, oil, water and corrosive media working environment.Suitable for medium, high speed and large torque shaft transmission.As well as the shaft transmission of various mechanical devices with little change in load, it is extremely versatile.

四孔Coupling diaphragmUse and maintenance

1. Before installation, clean the end faces of the two shafts and check the fit of the key grooves on the end faces;

2. After the four-hole coupling diaphragm is installed, run a shift normally, check all the screws, if found to be loose, tighten them, and repeat this for several shifts to ensure that they will not be loosened;

3. In order to prevent the fretting of the diaphragm during high-speed operation, causing microcracks and damage to the bolt holes of the diaphragm, solid lubricants such as molybdenum disulfide can be applied between the diaphragms or the surface of the diaphragm can be coated with anti-friction Layer processing

4. Long-term overload use and operation accidents should be avoided;

5. During work and operation, always check whether the diaphragm of the four-hole coupling is abnormal. If any abnormality occurs and perform maintenance

The correct choice of four-hole coupling diaphragm:

1. The diaphragm of the four-hole 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 some 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 the four-hole 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.

3. Four-hole coupling diaphragm is often used in servo systems. The diaphragm has good torque rigidity, but it is slightly inferior to bellows coupling.

4. On the other hand, the four-hole coupling diaphragm is very delicate, and it is easy to be damaged if it is misused or not installed correctly during use.Therefore, it is very important to ensure that the deviation is within the tolerance range of the normal operation of the coupling.

5. Adjust the model according to the shaft diameter:

The initially selected coupling dimensions of the bearing coupling, that is, the shaft hole diameter d and the shaft hole length L, should meet the requirements of the shaft diameters of the driving and driven ends, otherwise the coupling specifications must be adjusted according to the shaft diameter d.

It is a common phenomenon that the shaft diameters of the driving and driven ends are different. When the torque and speed are the same, and the shaft diameters of the driving and driven ends are different, the coupling model should be selected according to the larger shaft diameter.In the newly designed transmission system, the seven shaft hole types specified in GBT3852 should be selected, and the J1 shaft hole type is recommended to improve versatility and interchangeability. The shaft hole length is in accordance with the i-bearing coupling product standard. .
