Curved Jaw Couplings

The Curved Jaw Coupling is mainly composed of two metal claw plates and an elastic body. Two metal claw plates are generally made of 45 steel, but in cases where load sensitivity is required, aluminum alloy or stainless steel materials may also be used. Elasticity is usually made of materials such as engineering plastics, rubber, or high-strength wear-resistant polyurethane, responsible for transmitting torque and compensating for axial, radial, and angular displacement.

The working principle of the Curved Jaw Coupling is to use a plum blossom shaped elastic element placed between the two halves of the coupling claws, and compensate for the relative displacement between the two shafts through the deformation of the elastic body, while achieving torque transmission. When there is a relative offset between the two axes, the elastic element will undergo corresponding elastic deformation, playing an automatic compensation role, thereby ensuring the smoothness and reliability of the transmission.

Main Features 

• Strong compensation capability: Curved Jaw Couplings have significant axial, radial, and angular compensation capabilities, which can adapt to various complex shaft transmission requirements under various working conditions.
  

• Vibration reduction and buffering: Due to the presence of elastomers, Curved Jaw Couplings have good vibration reduction and buffering performance, which can reduce the vibration and noise of the transmission system.
  

• Simple structure: Curved Jaw Coupling has a compact structure, light weight, and small moment of inertia, suitable for medium and high-speed applications.
  

• No lubrication required: Curved Jaw Couplings do not require lubrication, require less maintenance, and can operate continuously for a long time.
  

• Electrical insulation: Some claw type couplings also have electrical insulation properties, suitable for situations that require electrical isolation.

Curved Jaw Couplings are widely used in various fields such as metallurgy, mining, petroleum, chemical, lifting, transportation, light industry, textile, water pumps, fans, etc. Especially in working environments with frequent starting, forward and reverse rotation, medium high speed, moderate torque, and high reliability requirements, Curved Jaw Couplings perform well.

The installation of claw type couplings is relatively simple, but the following points should be noted:

• Before installation, check whether the two shafts are concentric, and whether there are any debris or damage on the surfaces of the two shafts and the inner holes of the coupling.
  

• Suitable tools and methods should be used during installation to avoid damage to the coupling or shaft.
  

• After positioning is completed, the coupling should be tightened and fixed according to the specified tightening torque to ensure its stability and reliability.

In terms of maintenance, Curved Jaw Couplings do not require special maintenance. They only need to regularly check the wear of the elastic body and replace damaged elastic bodies in a timely manner.

Precautions

• When choosing a claw type coupling, the appropriate model and specification should be selected according to the actual working conditions and requirements.
  

• Avoid exceeding the rated torque and speed range of the coupling to avoid damaging the coupling or affecting the transmission effect.
  

• When used in high temperature, low temperature, or corrosive environments, Curved Jaw Couplings with corresponding temperature and corrosion resistance properties should be selected.

Curved Jaw Couplings play an important role in the field of industrial transmission due to their unique structure and excellent performance. The correct selection and use of Curved Jaw Couplings are of great significance for ensuring the smooth operation of the transmission system and improving the service life of equipment.
