Shaft couplings in compactors are exposed to severe operational stress, including continuous high torsional forces, immense vibration, and repeated impact shock from the compaction action. These joints must maintain perfect alignment and prevent any slippage to ensure power transmission integrity. Failure leads to immediate mechanical breakdown. This is a non-negotiable High Strength, Permanent application.
INCURE WeldLock™ 347 Retaining Compound (Green)
The INCURE WeldLock™ 347 Retaining Compound is the definitive choice for securing shaft couplings in heavy-duty compactors. It provides a superior, permanent structural bond designed to withstand the extreme dynamic loads and fatigue inherent in compaction machinery.
| Key Feature | Performance for Compactor Shaft Couplings |
| High Strength, Fast Curing | Creates a monolithic, zero-backlash joint that resists maximum torsional and shear forces and absorbs continuous impact shock, permanently locking the coupling to the shaft. |
| Temperature Resistance (175∘C) | Maintains full structural integrity under sustained operational heat generated by the drive system. |
| Ideal Gap Fill (Up to 0.15mm) | Perfectly secures standard press-fit couplings, eliminating the microscopic clearances that cause fretting and joint failure under high dynamic load. |
| Core Application | Suited for securing high-load rotating elements in motors and mechanical drives, matching the severe demands of heavy industrial machinery. |
Application Steps: Installing Compactor Shaft Couplings
For maximum structural integrity and reliable, permanent retention of the shaft coupling, follow these steps:
1. Surface Preparation (The Foundation)
- Clean: Thoroughly clean both the shaft surface and the coupling bore. Surfaces must be absolutely free of all contaminants (oil, grease, etc.). Use an industrial cleaner (e.g., acetone) and wipe dry.
- Activate (If Needed): For maximum cure speed, apply a chemical activator to the bond surfaces and allow it to flash off completely.
2. Product Application
- Apply: Apply a continuous, thin coating of WeldLock™ 347 around the full circumference of either the shaft or the internal bore of the coupling.
- Ensure Coverage: Ensure the adhesive completely wets the entire mating surface as the components slide together.
3. Assembly and Curing
- Assemble: Immediately slide or press the coupling onto the shaft. Ensure the components are fully seated and aligned correctly before the compound fixtures.
- Wipe Excess: Remove any excess adhesive visible outside the joint immediately after assembly.
- Cure: Allow the assembly to fixture before handling (typically 5 minutes). Allow a full 24 hours for the compound to reach maximum structural strength before placing the compactor into service.
