Dynaflex® Shear-Type Couplings

Rated: 1/50 to 1 hp at 1750 rpm

LORD Dynafl ex Shear-Type Couplings are compact, one-piece fl exible couplings economically constructed to isolate low-frequency vibration and accommodate multi- directional misalignment.

These couplings reduce the adverse effects of transient shock torques, torsional vibration, noise and misalign- ment associated with small equipment drivelines. This results in longer service life, smoother, quieter operation, less maintenance, and lower cost for your end product.

Shear-Type fl exible couplings are useful in many small equipment driveline applications. Multi-directional misalignment capabilities make them ideally suited for fractional horsepower drivelines demanding noise reduc- tion, vibration isolation and maintenance-free operation.

Typical applications include:

•Information Systems – Motor drive, printer rollers, indexing devices, linear actuator, drives and card sorters

•Hospital Bed – Actuator drive

•Dynamometer – Driveline

•Tachometer – Driveline

•Pumps, Blowers, Compressors – Driveline

Features and Benefits

•High torsional defl ection

•Easy installation

•Versatile application potential - fractional horsepower couplings are available in a range of sizes to permit matching a specifi c coupling to your application.

•One-piece construction – convenient for small equipment with fractional horsepower requirements. Specifi ed torque rating allows 15° angular defl ection for excellent vibration isolation.

•Multi-directional misalignment accommodation – elas- tomeric fl exibility accommodates misalignments up to 1/32 inch parallel, 2° angular.

•Vibration isolation – low torsional stiffness is achieved with the shear-type fl exible coupling because

the rubber is loaded in shear. This allows for low system natural frequencies and excellent driveline disturbances.

•Shock protection – torsional shock loads are attenu- ated by torsional defl ection of the elastomer. Torsional fl exibility smooths out rotational disturbances and protects system components from early fatigue failure.

•Noise reduction – no metal-to-metal contact; elasto- meric barrier reduces gear noise, transmission and motor hum between shifts.

•Maintenance-free – elastomer fl exibility accommo- dates all motion without metal-to-metal wear, elimi- nates the need for lubrication.

•Long service life – Dynafl ex Shear-Type Couplings have proven themselves under demanding service conditions. Elastomers resist effects of abrasive mate- rials, oil and grease.

•Attachment – shear-type fl exible couplings are avail- able in an assortment of bore sizes. Refer to Table 1.

•Constant velocity – inherent design properties produce a rotational constant velocity.
