Stainless steel diaphragm coupling diaphragm

The diaphragm coupling structure is mainly composed of three parts: the left flange, the right flange, and the metal diaphragm group. The left and right flanges are the output end and the input end of the coupling respectively, and the metal diaphragm group is the torque transmission. , Deflection angle adjustment assembly, the left and right flanges of the coupling are made of 45# steel forgings, which can be realized by conventional processing technology, and the metal diaphragm group is the key component of the entire coupling.

Botou Shengxin Coupling Factory provides various types of diaphragm couplings. The material used for the diaphragm is stainless steel. After the precision technology of our factory-vacuum heat treatment and cryogenic treatment, both the strength of the material and the material are improved. Of resilience.Welcome to map and customize.

The diaphragm of the stainless steel diaphragm coupling mainly bears 4 kinds of forces:

(1) Film stress caused by torque.The force generated by the torque on one side is evenly distributed on the four spaced bolt holes. On all 4/1 diaphragms, the force acts on the middle of one side of the middle bolt hole in the circumferential direction to fix the radial displacement and the axial direction. Displacement.

(2) Centrifugal stress produced by centrifugal inertial force.High-speed mechanical centrifugal inertial force is important in the stress calculation of the structure. The centrifugal inertial force can be loaded according to the radial unit body force f=2rρ(2πn/60), and the direction is radially outward. In the formula, n is the speed and r is The radius, ρ is the density.Fix the radial displacement, circumferential displacement and axial displacement of the middle bolt hole, and there is no other load around it.

(3) Bending stress caused by axial installation error.Due to the actual installation error in the axial direction, the diaphragm is installed along the axial direction and bends and deforms.The displacement is loaded in the axial direction of the middle bolt hole, and the radial displacement and the axial displacement are fixed.

(4) Bending stress caused by angular installation error (periodical profit).Due to the actual installation error in the axial angular direction, the diaphragm is periodically deformed along the axial direction, and it is the main factor that determines the fatigue life of the diaphragm.
