Resilient Couplings

High-Performance Resilient Couplings

AniGears AR Series Resilient Couplings are high-performance, torsionally flexible couplings designed to provide an optimum balance of shock absorption, torsional flexibility, and positive torque transmission.

They transmit power through a specially contoured spring steel grid fitted between two precision-machined hubs and enclosed within a lubricated steel cover.

The grid flexes under load, absorbing shocks and torsional vibrations while accommodating limited angular, parallel, and axial misalignments.

This design combines the advantages of both rigid and flexible couplings, offering smooth power transmission and protection for connected equipment from sudden torque fluctuations.

AniGears AR Couplings are engineered for quiet operation, long life, and fail-safe performance, making them ideal for medium to heavy-duty drives.

All metallic components are phosphated to resist corrosion and to ensure excellent lubrication retention.

Installation Steps

Easy Installation Steps

Clean all components before assembly.
Mount hubs on shafts with proper key fits.
Align hubs and maintain specified spacing between them.
Insert grid into the hub grooves and pack with grease.
Fit cover halves ensuring gasket seals properly.
Tighten bolts evenly and diagonally.
Verify alignment post-assembly.

Maintenance

Easy Maintenance

Inspect grid periodically for cracks, wear, or deformation.
Replace seals if hardened or damaged.
Maintain proper grease level to ensure smooth, quiet operation.
Keep the coupling area free of dirt, oil, or solvents.

Features & Advantages

Design & Operating Features

Torsional Flexibility

The spring steel grid flexes under load, absorbing torsional vibrations and cushioning shock loads.

Misalignment Compensation

Accommodates angular, parallel, and axial misalignments without excessive bearing or shaft stresses.

Compact & Efficient Design

High torque capacity for compact dimensions; suitable for confined space installations.

Fully Enclosed Lubrication

Grease-lubricated cover ensures quiet operation and long service life by preventing dust or moisture entry.

Shock & Vibration Damping

Grid design effectively dampens sudden torque peaks, protecting connected machinery.

Fail-Safe Performance

Even if the grid fails, metallic contact between hubs permits limited torque transmission to prevent drive interruption.

Ease of Maintenance

The grid can be replaced easily without moving connected machinery. Grease nipples allow quick relubrication.

Phosphated Finish

All metallic parts are phosphated, not painted or CEDcoated, to ensure compatibility with grease lubrication and to resist corrosion while retaining lubricant.
