Diaphragm coupling is a common mechanical transmission device, which is used to connect two rotating parts of non-coaxial line and transmit torque and rotary motion. It has the characteristics of simple structure, convenient installation and maintenance, high reliability and so on, and is widely used in industrial production in various fields.

The function of diaphragm coupling mainly includes the following aspects:

Transmission of torque: diaphragm coupling can transmit the torque of motor, engine and other power devices to mechanical equipment to realize the transmission and conversion of power. Due to the structural characteristics of diaphragm coupling, it can maintain high accuracy and stability when transmitting torque, reduce friction and vibration during transmission, and reduce energy consumption and noise of transmission system.

Adjust axial offset and angle deviation: In actual industrial production, there may be axial offset and angle deviation between axes due to manufacturing and installation errors of equipment. Diaphragm coupling has certain adaptability and can accommodate axial deviation and angular deviation in a certain range. By using diaphragm coupling, axial force and axial vibration can be effectively reduced, premature damage and unstable operation of equipment can be avoided, and production efficiency and product quality can be improved.

Buffering and vibration reduction effect: The diaphragm coupling has certain flexibility, which can absorb part of the impact and vibration in the transmission process and play the role of buffering and vibration reduction. Especially in high-speed and high-load transmission system, diaphragm coupling can effectively reduce the impact and vibration on equipment, prolong the service life of equipment and improve production efficiency and quality.

Adjust the transmission angular velocity: For some devices that need to adjust the rotating speed, the diaphragm coupling can realize different transmission ratios by changing the relative positions of the two transmission shafts. In this way, the transmission angular velocity can be adjusted according to the actual needs to meet different production requirements.

Protect the safety of equipment: diaphragm coupling can play a protective role when the equipment is overloaded, blocked and other abnormal situations occur. When the transmission system fails or is overloaded, the diaphragm coupling can break itself or the sliding sleeve jumps out, so as to prevent the failure from affecting the normal operation of the main engine and the transmission system and improve the safety and reliability of the equipment.
