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.

How Does a Gear Coupling Protect Connected Equipment from Shock Loads and Vibrations?

Gear couplings are designed to provide excellent protection to connected equipment from shock loads and vibrations, making them ideal for use in demanding and heavy-duty applications. The design and features of gear couplings that contribute to this protection include:

  • Flexible and Rigid Elements: Gear couplings consist of two hubs with external gears that mesh together. Between these two hubs, there is a center sleeve with internal gear teeth. The center sleeve acts as a flexible element, while the outer hubs act as rigid elements. This combination allows the gear coupling to transmit torque while absorbing and dampening shock loads and vibrations.
  • Misalignment Compensation: Gear couplings can accommodate angular, parallel, and axial misalignment between shafts. When the connected equipment experiences misalignment due to dynamic forces or shock loads, the gear coupling can flex and adjust to these changes, preventing excessive stress on the shafts and equipment.
  • High Torsional Stiffness: Gear couplings offer high torsional stiffness, meaning they have minimal angular deflection under load. This stiffness helps maintain precise alignment and reduces the likelihood of damage to the connected equipment caused by misalignment-induced vibrations.
  • Load Distribution: The toothed gear design of gear couplings ensures a large surface area of contact between the gears. This spreads the torque evenly across the gear teeth, resulting in a uniform distribution of load and reducing the concentration of stress on specific areas.
  • Damping Characteristics: The flexible center sleeve in the gear coupling acts as a damping element that absorbs and dissipates vibrations, further protecting the connected equipment from harmful oscillations.
  • High-Speed Balancing: Gear couplings are precisely balanced during manufacturing to minimize vibrations and ensure smooth operation even at high speeds. Proper balancing helps prevent resonances and reduces the impact of shock loads on the connected equipment.

By effectively absorbing and dampening shock loads and vibrations, gear couplings extend the life of the connected equipment and surrounding components, reduce maintenance requirements, and contribute to a more reliable and efficient mechanical system. However, it is essential to select the appropriate size and type of gear coupling based on the specific application and operating conditions to ensure optimal protection and performance.
