Jaw Coupling

The jaw coupling is a highly efficient coupling that consists of two metal hubs and an elastomer spider in between. It provides excellent torsional stiffness and misalignment capabilities, making it suitable for various applications. The spider is typically made of polyurethane or rubber, providing vibration damping and shock absorption.

Oldham Coupling

The Oldham coupling is a three-piece coupling that utilizes two hubs and a center disc. It compensates for angular misalignment and provides constant velocity transmission. The center disc is made of a low-friction material such as acetal or nylon, ensuring smooth operation and minimal wear.

Bellows Coupling

The bellows coupling is a flexible coupling that consists of two end hubs and a thin-walled metal bellows. It compensates for axial, angular, and parallel misalignments, while maintaining high torsional stiffness. The bellows is typically made of stainless steel, providing corrosion resistance and durability.

Disc Coupling

The disc coupling is a versatile coupling that utilizes thin metal discs to transmit torque. It can accommodate high misalignment and torsional stiffness requirements. The discs are typically made of stainless steel or aluminum, providing excellent resilience and fatigue resistance.

Grid Coupling

The grid coupling is a robust coupling that features a split cover and a flexible grid element. It provides high torque capacity, misalignment capabilities, and damping characteristics. The grid element is made of high-strength spring steel, ensuring long-lasting performance and shock absorption.

Diaphragm Coupling

The diaphragm coupling is a flexible coupling that consists of two hubs and a thin metal diaphragm. It provides high torsional stiffness, zero backlash, and excellent misalignment compensation. The diaphragm is typically made of stainless steel, offering corrosion resistance and high fatigue life.

Taper Lock Coupling

The taper lock coupling is a friction-based coupling that utilizes a taper and keyway connection. It provides secure shaft locking and easy installation and removal. The coupling is typically made of steel, ensuring high strength and durability.

Universal Joint Coupling

The universal joint coupling is a flexible coupling that accommodates misalignment in multiple directions. It consists of two yoke assemblies connected by a cross-shaped spider. The yoke assemblies are typically made of steel, providing robustness and torque transmission capabilities.

Beam Coupling

The beam coupling is a flexible coupling that utilizes multiple spiral cuts to provide flexibility and torsional stiffness. It is commonly used in applications with low torque requirements and minimal misalignment. The coupling is typically made of aluminum or stainless steel, offering lightweight and corrosion resistance.

Magnetic Coupling

The magnetic coupling is a non-contact coupling that utilizes magnetic forces to transmit torque. It provides hermetic sealing and eliminates the need for mechanical seals. The coupling is commonly used in applications where leakage prevention and isolation are critical.

Gear Coupling

The gear coupling is a highly robust coupling that utilizes gear teeth to transmit torque. It provides high torque capacity and misalignment capabilities. The gear teeth are typically made of alloy steel, ensuring durability and efficient power transmission.

Flex Coupling

The flex coupling is a flexible coupling that utilizes an elastomeric element to transmit torque. It provides vibration damping, shock absorption, and misalignment compensation. The elastomeric element is typically made of rubber or polyurethane, offering flexibility and resilience.

Pin & Bush Coupling

The pin & bush coupling is a simple coupling that consists of two hubs, a pin, and a bush. It provides flexible torque transmission and misalignment compensation. The pin and bush are typically made of steel, ensuring strength and durability.

Clamp Coupling

The clamp coupling is a versatile coupling that utilizes a split clamp and screws to provide secure shaft connection. It accommodates high torque requirements and misalignment. The coupling is commonly made of steel or aluminum, offering strength and easy installation.

Chain Coupling

The chain coupling is a flexible coupling that utilizes a chain to transmit torque. It provides high torque capacity and misalignment compensation. The chain is typically made of steel, ensuring strength and durability.

– Select a motor coupling that can handle the calculated torque.

2. Misalignment Compensation:
– Determine the types and magnitudes of misalignment present in the system.
– Choose a motor coupling that can accommodate the identified misalignments.

3. Speed:
– Determine the operating speed range of the system.
– Select a motor coupling that can handle the required speeds without compromising performance.

4. Environmental Conditions:
– Consider the temperature, humidity, and other environmental factors.
– Choose a motor coupling that can withstand the specified conditions.

5. Space Limitations:
– Evaluate the available space for the motor coupling installation.
– Select a motor coupling with appropriate dimensions and compact design.
