The flexible plum coupling is composed of two semi-couplings with convex claws and a plum-shaped flexible non-metallic element whose hardness can be adjusted. By embedding the plum-shaped flexible element into the two semi-couplings to realize the connection, plum blossom coupling has the characteristics of compensating the relative displacement of the two axes, reducing vibration and buffering, simple structure and easy maintenance without lubrication.
Flexible claw coupling, also known as flexible plum blossom coupling or jaw coupling, is a widely used mechanical component in the field of industrial transmission.
The Flexible Jaw Shaft 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 also playing a role in vibration reduction, buffering, and electrical insulation. When there is a relative offset between the two axes, the elastic element will undergo corresponding elastic deformation, thereby playing an automatic compensation role.
Characteristics and advantages
Compact structure: The Jaw Flexible Coupling has a compact structure, small radial size, light weight, and small moment of inertia, making it suitable for medium and high-speed applications.
Large compensation capability: With significant axial, radial, and angular compensation capabilities, it can adapt to various complex working conditions.
Vibration reduction and buffering: By deforming the elastic body, it can effectively reduce vibration and impact, and improve the working performance of the transmission system.
Electrical insulation performance: Elastic materials have good electrical insulation performance, ensuring the safety and reliability of the transmission system.
Maintenance free: Claw couplings do not require lubrication, require less maintenance, and can operate continuously for a long time.
Multi 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, Jaw Type Couplings demonstrate their unique advantages.
The installation and maintenance of Plum Couplings are relatively simple. During installation, it is necessary to maintain the concentricity of the two shafts and clean the inner hole of the coupling and the surface of the installation shaft. During maintenance, the elastic body can be quickly replaced without disassembling the main coupling shaft sleeve, reducing maintenance costs and time.
precautions
Reasonable selection: When choosing a claw type coupling, it is necessary to make a reasonable selection based on parameters such as torque, speed, axial and radial displacement in the actual working environment.
Regular inspection: Regularly check the wear of the claw coupling and replace severely worn components in a timely manner.
Avoid overload: During use, avoid exceeding the maximum load-bearing capacity of the claw coupling to prevent damage to the elastic components or system problems.
Jaw Flex Couplings play an important role in the field of industrial transmission due to their unique structure and superior performance.
