FOR GAS OR DIESEL ENGINE PULLEY-END

OPERATION

 

(For auxiliary pump drives)

 

GUARDEX Type FLD provides a shiftable sleeve, which

can be retracted to allow for V- belt replacement without

disassembling the pump.

 

 

Field Proven

5-90 HP, approximately .040" axial travel, .030" parallel

misalignment, 2° angular misalignment. Double crowned gear teeth for

low contact pressure and free axial travel to protect pump bearing.

 

Pump bores available with SAE and metric splines and cross-bolt clamping. Wide temperature range without lubricants or maintenance.

Flanges for SAE and many special engine pulleys.

 

MINIMUM SPACE:              The entire coupling length is normally mounted inside the housing face

                                          requiring only a flat pump mounting plate. The reduced space may save in

                                          the equipment frame, sheet metal or hydraulics.

 

FREE AXIAL TRAVEL:        Crowned teeth slide freely in the nylon spline with approximately .080" axial

                                          travel. Any shaft float is absorbed by the coupling and not transmitted to

                                          the pump components.

 

BLIND ASSEMBLY:            Pump hub gear ring fits through the pilot hole of the plate. Faster assembly

                                         at lower cost and no inspection ports or hand holes necessary.

 

CROWNED GEAR TEETH:  Provides for angular misalignment, preventing angular force on the pump

                                         shaft bearings and seals.

 

HEAT STABLE:                  Fiberglass reinforced nylon designed to operate in diesel engine ambients

                                         without air circulation. Dimensionally stable to 250° F.

FEATURES OF THE GUARDEX COUPLING

 

Double crowned tooth design provides free axial

movement, low friction and minimum stress during

misalignment.

 

Designs are available with up to ³/₈" axial travel.

 

Molded nylon sleeve with high torsional stiffness, free from any internal frictional losses or heat build-up. A torsionally stiff coupling with minimum backlash.

 

Nylon and steel components allow high ambient temperature operation without lubrication or maintenance. Continuous operating ambients of 180^oF. With peak temperatures to 250^oF.

 

Nylon sleeves resistant to dirt, moisture, most chemicals and petroleum products. No lubrication, seals or retainers to maintain. Easy clean-up and visual inspection.

 

Compact and lightweight design with high torque and low inertia. Minimum shaft gap for close-coupled applications.

 

Precision molded concentric sleeve and hubs for high-speed applications. No bolts, pins, flanges or protrusions to affect balance or safety. Smooth exterior surface.

 

Blind assembly with slip-together components for easy inspection and adjustment without disassembly. Metric / Standard bores available.

 

DIRECTLY INTERCHANGEABLE WITH BOWEX* COUPLINGS

Coupling has additional axial travel for DEMAG brake motors.

 

Sleeve held to one hub with snap rings.

 

Opposite hub has free axial travel of .120" to .180"

 

Special hub lengths available

SERIES "M" FLEXIBLE SHAFT DRIVE COUPLINGS

 

The Series "M" line features 1/4" to 3 3/4" bores, 1/2 HP-294 HP. This double crowned tooth gear coupling provides free axial movement, low friction and minimum stress during misalignment. Lubrication free nylon sleeve.

The steel hubs are available with metric bores & keyways, tapered bores, or

SAE splines. They also have blind assembly, free axial travel and

splined / metric bores.
