Product Description

A coupling is a mechanical component used to firmly connect the driving shaft and driven shaft in various mechanisms, allowing them to rotate together and transmit motion and torque. Couplings can also connect shafts to other parts, such as gears or pulleys. Typically, a coupling consists of two parts connected by a key or clamping fit, and fastened to the two shaft ends. They compensate for deviations, including axial, radial, angular, or combined offsets between two shafts due to manufacturing inaccuracies, installation errors, deformation, or thermal expansion, while also absorbing shocks and vibrations.

Couplings are essential to connect shafts in different mechanisms, primarily by rotation, thus transferring torque. Under high-speed power, they provide buffering and damping functions, resulting in a prolonged service life and improved working efficiency.

Function of the Coupling

Couplings serve various functions, including:

  • Connecting two shafts or shafts with rotating parts to transmit motion and power without disengagement under normal circumstances.
  • Acting as safety devices to prevent excessive loads and providing overload protection.
  • Transferring torque, compensating for installation deviations, absorbing equipment vibrations, and buffering load impacts.
  • Absorbing and compensating for deviations between shafts through their own deformation.

The deviation between the shaft and the coupling can be divided into three main types. The connection is achieved by inserting the device shaft into the coupling’s shaft hole.

Key Roles of Couplings:

  1. Connecting the drive shaft and driven shaft to rotate and transmit torque together, with additional roles in buffering, damping, and improving dynamic performance.
  2. Eliminating the inertia of the radial force and weakening the starting power during motor startup.
  3. Conducting power and torque transmission, thus enhancing the transmission system’s performance.
  4. Reducing and buffering vibrations to varying degrees.
  5. Disconnecting under excessive loads for protective purposes.
  6. Facilitating easy maintenance.
  7. Changing the drive direction.
  8. Correcting concentricity with axial, radial, and angular compensation performance.

Types of Couplings

Bellows Coupling

The bellows coupling consists of two hubs and thin-walled bellows welded or bonded together. It has a clamping structure at the input end, which generates pre-tightening force through clamping screws, ensuring a firm connection with the power input shaft. Bellows couplings can correct radial, axial, and angular deviations, transmitting torque with zero backlash and accommodating different equipment requirements.

Plum Coupling

The plum coupling is widely used for its elastomeric balance accessory, enabling zero-backlash torque transfer and shock absorption. The elastomers, made from engineering plastics or rubber, determine the drive system’s characteristics, making the plum coupling ideal for applications with strong vibrations.

Safety Coupling

Relying on spring force and shape, the safety coupling protects adjacent drive components from overload damage. It features various types such as synchronous, stepping, and failure protection types. The service life of the safety coupling depends on the disengagement speed and holding time, with no wear when engaged, requiring no maintenance or additional refueling.

Rigid Coupling

Rigid couplings are torsionally rigid, transmitting torque without turning clearance even under load. Suitable for applications with strict alignment requirements, rigid couplings offer maintenance-free performance, ultra-oil resistance, and corrosion resistance. They are particularly advantageous in motor test systems with high alignment accuracy.

Long Shaft Coupling

Standard long-shaft couplings can reach up to 6 meters without intermediate support. Both ends are connected by high-performance stainless steel or high-strength aluminum, with the middle pipe available in materials such as steel, aluminum, or carbon fiber. The allowable working speed depends on the joint shaft’s total length, which can be adjusted as needed.

Diaphragm Coupling

Diaphragm couplings transfer torque through friction and diaphragm assembly, avoiding stress concentrations, backlash, and micro-displacement common with shoulder bolts. They offer near-unlimited service life and increased torsional rigidity, compensating for various combined shaft assembly errors within specified tolerances.
