Description

1. Product Description

LOCUS Couplings are high-performance mechanical connectors used to transmit torque between shafts in industrial applications. Engineered with precision, these couplings accommodate misalignment, reduce vibration, and protect equipment against overloads. Available in multiple types and materials, Locus Couplings are suitable for pumps, compressors, gearboxes, motors, and heavy-duty machinery.

3. Working

Couplings connect two rotating shafts and transmit power (torque) from one to another while accommodating minor misalignments or vibration. They reduce mechanical wear and protect connected equipment from shock loads, torsional vibration, and shaft misalignment.

4. Principle

The basic principle is torque transmission with flexibility and damping. The coupling either directly engages both shafts (rigid) or uses an elastomeric or mechanical buffer to compensate for misalignments and absorb shocks (flexible).

5. Assembly Process

Select correct coupling type and size based on shaft diameter and torque.
Clean both shaft ends.
Insert keys (if applicable) into shaft keyways.
Mount coupling halves on shafts.
Align coupling halves using feeler gauge or dial indicator.
Tighten set screws or bolts as per torque specification.
Insert spacer or spider (if applicable).
Perform a trial rotation for alignment validation.

6. Installation Process

Disconnect power source before installation.
Mount and align both coupling halves.
Ensure there’s no axial force or bending.
Secure using grub screws or clamping bolts.
Use proper tools to tighten coupling bolts (torque wrench preferred).
Check rotational smoothness and noise.
Run machine at low RPM to test.
Retighten after 2-4 hours of running.

7. Troubleshooting Guide

Issue	Cause	Solution
Excessive Vibration	Misalignment	Realign shafts
Coupling Breakage	Overload or wrong size	Use correct torque-rated coupling
Unusual Noise During Running	Loose bolts or wear in insert	Retighten / Replace worn insert
Shaft Slip	Loose fit on shaft	Ensure proper tightening & key fitting
High Temperature Rise	Lack of lubrication (if required)	Lubricate or switch to non-lube type

9. FAQ – Frequently Asked Questions

Q1: What type of coupling is best for high torque?
A: Gear or disc couplings are best suited for high-torque applications.

Q2: Can I use PU Jaw couplings in corrosive environments?
A: Yes, with stainless steel or anodized aluminum variants and chemical-resistant elastomers.

Q3: How do I choose between rigid and flexible couplings?
A: Use flexible couplings when misalignment or vibration is expected. Use rigid only if precise alignment is assured.

Q4: Do Locus Couplings come with warranty?
A: Yes, Locus offers 1-year manufacturing warranty on all coupling products.

Q5: Can you supply OEM or white-labeled couplings?
A: Yes. We offer OEM and white-label manufacturing under NDA.
