Claw type surface to surface design, has the function of protecting, vibration and shock can produce effective damping and reduce the running in process. Claw type teeth 2 sleeve are offset in the circumferential direction, in the gap in a quincunx elastic body of involute. When small deviations in the installation, the elastic body avoids the stress concentration. Can effectively compensate the axial, radial and angular displacement. Column pin coupling elastomer old-fashioned type of large volume, shear effect, easy to damage, while the elastic body new claw type couplings only under the extrusion pressure, so it can withstand greater load, better wear resistance, longer service life. And both the level of installation, and can be installed vertical.

Characteristics of CJ series coupling products:

1 has the advantages of simple structure, stable performance, stable operation

2 3 component structure, easy installation and maintenance.

3 hub and elastic body, a variety of materials to choose from, to ensure that all can work stably in various environments.

4 using a surface matching claw type shaft hub and involute arc elasticity, can avoid the stress concentration, the effective transmission of higher torque, more resistant to abrasion, longer service life.

A small protuberance pad 5 elastic body, can isolate the metal shaft hub contact in coupling installed, effective insulation, no need of lubrication. Coupling of deviation of the remedy is deformation occurs through the elastic force at the finish.

Description: the polyurethane elastomeric is a new material of polymer synthetic between rubber and plastic. It has both high strength of plastic and high elasticity of rubber. Its characteristics are: 1, a wide range of hardness. It still has rubber elongation and resilience at high hardness. The polyurethane elastomeric has a hardness range of Shore A10-D80. 2. high strength. At rubber hardness, the tensile strength, tear strength and load carrying capacity are much higher than general rubber material. At high hardness, its impact strength and flexural strength are much higher than plastic material. 3, wear-resistant. Its wear resistance is very outstanding, generally in the range of 0.01-0.10cm3/1.61km, about 3-5 times than rubber material. 4, oil resistant. The polyurethane elastomeric is a highly CHINAMFG polymer compound which has low affinity with non-polar mineral oil and is hardly eroded in fuel oil and mechanical oil. 5, good resistance to oxygen and ozone. 6, excellent vibration absorption performance, can do damping and buffering. In the mold manufacturing industry, it replaces rubber and springs.7, has good low temperature performance. 8, radiation resistance. Polyurethane is highly resistant to high energy radiation and has satisfactory performance at 10-10 deg radiation dose. 9, with good machining performance.

Materials Used in Manufacturing Gear Couplings

Gear couplings are designed to transmit torque between shafts while accommodating misalignment. To ensure the durability and reliability of gear couplings, manufacturers use a variety of materials, each with its specific properties. Commonly used materials in manufacturing gear couplings include:

  • Steel: Steel is the most widely used material for gear couplings. It offers excellent strength, durability, and resistance to wear and fatigue. Steel gear couplings are suitable for a wide range of applications, including heavy-duty industrial machinery.
  • Stainless Steel: Stainless steel is chosen for gear couplings that require resistance to corrosion and high-temperature environments. Stainless steel couplings are commonly used in food processing, pharmaceutical, and chemical industries.
  • Alloy Steel: Alloy steel is utilized to enhance specific properties, such as increased strength and improved performance under high loads and extreme conditions. Alloy steel gear couplings are ideal for demanding applications in heavy industries.
  • Cast Iron: Cast iron is known for its excellent machinability and good resistance to wear. Cast iron gear couplings are suitable for low to moderate torque applications and can be cost-effective in certain scenarios.
  • Non-Metallic Materials: In some cases, non-metallic materials like nylon or urethane may be used for specific gear coupling applications, especially in situations where electrical isolation or chemical resistance is required.

The choice of material depends on the application’s demands, including the torque, speed, environmental conditions, and budget considerations. Gear coupling manufacturers carefully select materials that will provide optimal performance and longevity while meeting the specific requirements of the intended application.
