The use characteristics of the diaphragm coupling and the structure of the stainless steel diaphragm

Couplings are widely used nowadays, and there are also many types of products sold on the market. As a type of diaphragm coupling in couplings, its application characteristics and structural methods What is it like? Let's give us a specific introduction.

The application characteristics of diaphragm coupling and the structure method of stainless steel diaphragm

Diaphragm coupling structure method: 4 holes 6 holes 8 holes 10 holes 12 holes

Operating features: 1. Don't be smooth, no need to protect it, it can fundamentally eliminate the vibration of the tooth-type diaphragm coupling due to tooth surface wear, and prevent the tooth-type diaphragm coupling from generating a new imbalance due to oil accumulation, etc. A series of troubles

2. It can be assembled and disassembled without disturbing the master and slave equipment, and the replacement of the diaphragm coupling can be completed within 2 hours, which improves the utilization rate of the equipment

3. It can work in harsh environmental conditions, it can work under 300 degrees Celsius, it can work in acid, alkali, salt spray and other corrosive environments

4. The ability to accept misalignment is strong, and it has certain ability to reduce vibration and noise. The misalignment can satisfy most of the misalignment requirements in the operation of power transmission equipment

5. Zero clearance, constant low unbalance, noise-free diaphragm coupling parts are selected for installation without gaps, no operating noise, and consistent initial dynamic balance accuracy

6. Applying predictable low additional negative to the connected equipment. Compared with similar flexible transmission elements, the diaphragm diaphragm coupling exerts the smallest predictable force and bending moment on the connected equipment.

7. With high power-to-quality ratio, it is especially suitable for connecting high-power power equipment

8. The non-linear change of the stiffness between the shafts can effectively limit the drift of the magnetic center of the motor

9. Diaphragm diaphragm couplings are often used in servo systems. The diaphragm has good torque rigidity, but it is slightly inferior to the bellows diaphragm coupling.

The structure method of the diaphragm of the diaphragm coupling:

1. Diaphragm method: successively connect polygonal ring shape, circular ring shape, separate connecting rod shape, spoke shape, formed diaphragm, waved diaphragm.

2. Features of successive polygonal ring and circular ring: Each diaphragm coupling is composed of several diaphragms of equal thickness. The outer edge of each diaphragm is arc-shaped, which has better elasticity, simple shape, convenient processing, but more elasticity Poor, in addition, the elasticity with a small number of sides is better than the elasticity with a large number of sides, but if the number of sides is too small, the stability will also decrease. When one-way operation is performed, only half of the ring side bears the transmission torque.

3. Features of separate connecting rod shape: Each diaphragm is composed of a single thin rod to form a polygon. The rod has a simple shape and is convenient to manufacture, but requires accurate hole spacing. Its operating function is basically the same as that of successive polygonal rings, but the strength and speed are Low, suitable for occasions where the size of the diaphragm coupling is restricted.

4. The characteristics of the spoke shape: Each diaphragm coupling is composed of several pieces. The screw holes on the outer and inner edges are separated and connected with the driving and driven half diaphragm couplings. Changes occur during operation. The forming hole is to add elasticity, because the difference between the inner and outer diameter of the elastic demand should not be too small, and it is generally appropriate to transmit medium and small power.

5. The characteristics of the formed diaphragm: Each diaphragm coupling is composed of a single diaphragm. The thickness of the diaphragm is regularly reduced from the inner to the outer hyperbola to maintain the same strength conditions. Its data utilization rate is high and the integrity is good. , Especially suitable for high-speed transmission, but the production precision of the diaphragm is higher.

6. The characteristics of the wavy diaphragm: The diaphragm is wavy in the axial section, with high elasticity and good compensation function.The single-piece hyperbolic type with equal thickness and unequal thickness of the diaphragm has better functions, and is now used more frequently.

The diaphragm of the diaphragm diaphragm coupling is generally made of stainless steel 304. After being processed by wire cutting, it is pierced with an iron buckle and riveted.The bolt holes of the diaphragm and diaphragm couplings are all reamed, one large and one small, and the other is reversed.

Specification for shaft hole and shaft length of diaphragm coupling

The diaphragm coupling is mainly due to the shaft connection of the motor, the reducer and the working machine. The shaft hole method, connection method and size mainly depend on the type and size of the connected shaft. The planning is generally based on the cylindrical and conical shaft depth. Standard planning shaft, shaft depth specification is for shaft

The diaphragm coupling is mainly due to the shaft connection of the motor, the reducer and the working machine. The shaft hole method, connection method and size mainly depend on the type and size of the connected shaft. The product planning is generally based on cylindrical and conical shafts. The deep specification of the planning axis, the axis depth specification is for the planning of the axis.Shafting transmission generally consists of one or several diaphragm couplings connecting the main and driven shafts to form a shafting transmission system to transmit rolling or motion.The diaphragm coupling is mainly due to the shaft connection of the motor, the reducer and the working machine. The shaft hole method, connection method and size mainly depend on the type and size of the connected shaft. The product planning is generally based on cylindrical and conical shafts. The deep specification of the planning axis, the axis depth specification is for the planning of the axis.

In the structural planning and series planning of various methods of diaphragm couplings, based on the size of the transmitted torque, the structure of the diaphragm coupling and the strength of the hub, determine the size of the shaft hole of the standard diaphragm coupling (Large and small shaft hole) and the length of the shaft hole, each specification only needs one kind of shaft hole length.In foreign countries, no matter which enterprise that produces diaphragm couplings, in the specifications of different diaphragm couplings, it is the only shaft hole length of each standard diaphragm coupling.Due to the misleading of GB/T3852, each specification in my country's diaphragm coupling product specification has a variety of shaft hole lengths corresponding to the change of the shaft hole. When the foreign diaphragm coupling specification is converted into the Chinese specification, it is also With the addition of various shaft hole lengths, it seems that only this can be considered a complete transformation.
