Applicable environment of serpentine spring coupling deviation and diaphragm elastic coupling

The serpentine spring coupling is a well-designed non-metallic coupling that relies on serpentine springs to transmit torque.Its vibration damping function is good, the use time is long, the load change is large, and the start is safe; the transmission efficiency is high, the operation is low, the noise is good, the smoothness is good, the design is simple, the assembly and disassembly are convenient, and the larger assembly bias is allowed.Align the assembly carefully and master the good deflection. Although the serpentine spring coupling allows larger assembly deflection, during assembly, the gap between the two-part couplings and the angular deflection should also be aligned within the regular value. , When assembling, measure the gap between the two couplings every 90, the difference between the larger value and the smaller value does not exceed 038mm, and the radial deviation is aligned.Place a ruler on the two-part coupling, measure it every 90, and check with a ruler. The radial deviation does not exceed 038mm.Choose a suitable lubricating grease oil injection point temperature ≥ 150 ℃, can resist the centripetal force, have a combination of stability, no impurities, not corrode carbon steel and nitrile rubber lithium-based grease is good.The smooth grease with sufficient amount of lubricating grease is especially important for the operation of the coupling, and it is recommended to review it annually.Use a dry grease gun to inject smooth grease until a proper amount of smooth grease overflows in the hole.

The main types and explanations of the deviation of the serpentine spring coupling are:

1. Axial deviation: refers to the axial deviation between the two connected shafts.

2. Parallel deviation: refers to the radial deviation between the two connected shafts.

3. Angle deviation: refers to the deviation angle between the two connected shafts.

In a special working environment, the precautions when using the coupling are mainly as follows: If the environment is corrosive, then stainless steel materials such as G1TS, T2TS, G2CS, G3TS, GS, and G5CS should be used.The rated torque on the data needs to be greater than the load torque of the system.Its dimensions and specifications must also comply with relevant design conditions and requirements.

1. It is suitable for medium and high-power transmission shafts connecting two coaxial lines, with corresponding compensation for the relative deviation of the two shafts, vibration reduction, and buffering performance. The working temperature is -30℃~+150℃, and the nominal torque is transmitted. 45~800000N.m.

2. Mainly used in rock crusher, crank reciprocating motion, reducer, metallurgy, mining, hoisting machinery, etc.

3. The shaft transmission of other kinds of machinery and equipment can be applied wherever there is a motor connected with a shaft, a motor connected with a reduction box or a shaft connected with a shaft.

Diaphragm elastic coupling is a mechanical element used to transmit torque and rotation angle.Each model has its characteristics.Please select the type that is more suitable for your needs from the product center.Refer to the specifications of the type you have selected and the inventory aperture size list, and select the product that is more suitable for your needs.Confirm that the rated torque, maximum speed and size of the coupling product you have selected are consistent with the equipment you will use this product.The larger torque of the coupling is twice its rated torque.The torque produced by the selected product during continuous operation should not exceed the rated torque of the coupling.The diaphragm is fastened to the sleeve with a pin and generally will not loosen or cause backlash between the diaphragm and the 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.

Applicable environment of diaphragm elastic coupling:

1. It is widely used in metallurgy, steel rolling, mining, chemical industry, shipbuilding, pumps, fans and other industries.

2. According to the transmission torque and flexibility, the connecting rods are divided into four, six and eight equal parts.

3. Large carrying capacity, large scope of application, long service life, nominal torque of 25~1000000N, m.

4. The working temperature is -20~+250℃, and no lubrication is required, and it can work in corrosive media.

5. Compared with gear couplings, it has simple structure, easy processing and maintenance, low vibration, no noise, and is suitable for use at high speeds.

6. Convenient for assembly, disassembly and inspection. The driving and driven parts of the transmission system can be disengaged without axial displacement during disassembly.

Fixing method of diaphragm-type elastic coupling: diaphragm-type elastic coupling. Keyway fixing method: suitable for high-torque transmission. In order to prevent axial sliding, it is usually used together with set screw fixation and clamping screw fixation.Diaphragm elastic coupling D-shaped hole fixing method: Generally, if the shaft of the motor is D-shaped, if the positioning screw cannot be fixed, the hole of the coupling can be processed to correspond to the size of the motor shaft The D-shaped hole is fixed with the positioning screw, so there is no need to worry about slipping.Expansion sleeve fixing method: The expansion sleeve is compressed and fixed by tightening the four positioning screws on the end of the coupling. It is suitable for the connection and fixing of some stepping motors and servo motors with large torque, such as expansion sleeve diaphragm couplings, Expansion sleeve plum coupling, expansion sleeve bellows coupling, expansion sleeve diaphragm type elastic coupling, etc.Tighten the fixed shaft. The old-fashioned fixing method may cause damage to the shaft or difficulty in disassembly because the front end of the screw contacts the shaft.Diaphragm-type elastic coupling clamping screw fixing method: Utilize the tightening force of hexagon socket bolts to shrink the slit and clamp the shaft tightly.This method is convenient to fix and disassemble, and will not cause damage to the shaft, so it is a very common fixing method.
