ZL type elastic pin coupling how to choose correctly

ZL type elastic pin coupling in the production process is the need to use a variety of non-metallic elastic materials made of the pin, it is placed in the two half coupling flange hole, through the pin to complete the two half coupling connection, the coupling structure is simple, simple manufacturing, it is easier to install and replace the elastic components, do not need to move the two couplings. The material of elastic element (pin) is generally nylon 6, which has the ability to compensate the two axis deviation. The elastic part is subjected to shear when working, and the working performance is poor. It is only suitable for the medium speed transmission shafting with very low requirements. The pin in the shaft of the elastic pin gear coupling is shear and kneading during operation. The strength condition is to calculate the shear strength of the elastic pin on the cross section and the kneading strength of the pin and the wall of the pin hole.

ZL type elastic pin coupling how to choose correctly:

A, high power, heavy parts can choose the gear coupling. The bearing capacity of the gear coupling is better, and it has high elasticity and is not easy to be damaged.

Two, the requirements of the number of revolutions of the elastic pin gear coupling is more accurate, the requirements of the balance force is also relatively good, you can choose the diaphragm coupling, diaphragm coupling accuracy is better.

Three, if you want to consider the cost, installation and operation is convenient, you can choose the plum shape elastic coupling, plum shape elastic coupling has a simple structure, easy to operate, easy to install, but also the cost is fine, convenient maintenance.

The production process of ZL type elastic pin coupling is relatively complex, but the manufacturing procedure of the coupling parts is actually slightly more complex than the general coupling, but it is more convenient in the disassembly process, without moving the half coupling on the two shafts can be easily loaded and unloaded. The material of elastic pin is generally nylon 6. Elastic pin parts are subject to shear when working, and the working performance is poor. Because it can transfer large torque force, it requires very low medium speed transmission shafting to work, so attention should be paid to it when using.
