Quick Flex Couplings

Design Attributes

Timken quick flex couplings innovative design features two steel hubs, polyurethane insert, and a cover.

Insert and covers

Quick flex flexible urethane coupling insert are resistant to most chemicals and available four materials for varying temperature and torque needs.

• QUICK FLEX RED INSERT (STANDARD)
• The standard insert excels in vibration dampening and cushioning of shock loads.
• This insert is best for reversing applications or applications with quick starting and stopping of high-inertial loads.

• QUICK FLEX BLUE INSERT (HIGH TORQUE)
• This insert is well suited for applications with moderate to high torque.
• It delivers high torque while maintaining a degree of torsional softness and ability to dampen vibration.

.

• QUICK-FLEX BLACK INSERT
• This insert offers the highest torque rating.
• Quick-flex coupling with black insert is an excellent replacement for gear type coupling.
• This insert offers an operational temperature range of -50° C to 100° C.

• QUICK-FLEX WHITE INSERT (HIGH TEMPERATURE)
• Quick-flex white insert is made of a heat-resistant urethane compound for use in application where heat is a concern.
• These inserts can handle temperature up to 177° C (350° F) and provide torque capabilities equal to blue insert.

• QUICK-FLEX HIGH-SPEED COVER
• Quick-flex high-speed covers are designed for application where low torque and/or high speed is present
• QUICK-FLEX HIGH-SPEED SPLIT COVER
• These covers are ideal in an application where high torque is combined with high speeds while minimizing axial load.
• QUICK-FLEX ALUMINUM HIGH-PERFORMANCE COVER
• These covers are designed to minimize axial loading in all applications including high or low torque and high or low speed.
• QUICK-FLEX LOW-SPEED SPLIT COVER
• By minimizing axial loading, quick-flex low-speed split covers excel in applications where there is a high amount of torque and low speed.

Advantages

• More uptime-Timken coupling’s innovative design helps eliminate mechanical interference between the coupling hubs. As needed we can replace the urethane insert easily and quickly without removing the hub.
• Angular misalignment-Accepts shaft misalignment up to 2 degrees.
• Reduced inventory– The versatility of the Timken quick-flex design promotes components standardization across your plant, reducing the need to store multiple coupling style.
• Low maintenance– Elastomeric coupling requires no lubrication and therefore are low maintenance and very environmental friendly.

Sizes & Selection

• Timken quick-flex couplings are available in the range from 10 mm (0.37 in.) to 285 mm (11.25 in.).
• Continuous torque handling from 0.043 kNm (377 in.-lbs.) to 188.8 kNm (1,670,826 in.-lbs.).

To select the correct quick-flex coupling for your application use the below-mentioned formula

Design Torque (Nm) = Actual torque (Nm) x service factor

Actual Torque (Nm) = 9550 x kW/RPM
where:
kW = Drive kilowatts
RPM = Driveshaft revolutions per minute

Comparison

Quick-flex couplings transmit a higher level of torque in most cases, compared with the competitive averaged gear coupling rating.
