LOVEJOY 68514476505 Jaw Coupling Hub, Coupling Size CJ42/55, Spline, Powdered Metal

Lovejoy 68514476505 spline coupling hub is designed for power transmission in internal combustion engines, pumps, gear boxes, mixers and electrical motors. This jaw coupling is used with a coupling spider and a jaw coupling for power transmission across machinery shafts.

Working Mechanism:

• This jaw coupling is connected to shafts on both ends for accommodating slight angular misalignment.
• The flexible coupling spider handles the pressure and shaft misalignment through the jaw couplings.
• It features a bored end for connecting the shaft to the coupling.
• A flexible coupling spider is fixed inside the coupling jaws to connect both coupling hubs.
• The second jaw coupling is connected to the shaft as well.

Features:

• It has a fail safe design for performing even after elastomer failure.
• This jaw coupling has no metal to metal contact for minimising wear & tear during operation.
• It features powdered metal construction for preventing breakage under high torque transmission applications.
• It has curved jaws for allowing higher torque capacity with compact design.
• Lovejoy coupling spline style bore ensures easy and secure shaft installation while preventing slippage.

Compatible Accessories:

• Lovejoy Jaw Coupling Spiders: They are used with the jaw coupling set for power transmission while preventing metal to metal contact.

Frequently Asked Questions:

Q. What are Lovejoy spline couplers?

A. Spline couplings are mechanical components that are used for transmitting torque between rotating parts.

Q. How to choose the correct jaw coupling spider?

A. The coupling spider should have the same outside diameter as of the coupling hubs.

Q. How to know the jaw coupling size?

A. Users should check the bore size of the coupling to match the shaft connector size.

Q. Why are jaw couplings used?

A. These jaw couplings are used to transmit torque between two shafts while accommodating slight misalignment and damping system vibrations. It protects various components from damage & wear.

Q. Do Lovejoy jaw couplings require lubrication?

A. No, these jaw couplings do not require additional lubricant for coupling spiders or shaft connections. These couplings can transmit power for light, medium & heavy duty internal combustion & electrical motor power transmission applications without lubrication.

Q. What speed range are these jaw couplings suitable for?

A. These couplings can handle shaft speeds up to 6000 rpm.

Q. Are these couplings suitable for high-temperature conditions?

A. Yes, Lovejoy jaw couplings are ideal for usage within -50 to 248 degrees F temperature range.
