Securing components (like eccentric weights or drive hubs) onto a vibrating screen motor shaft is one of the most extreme applications for a retaining compound. This joint is subjected to continuous, high-amplitude vibration, massive torsional stress, intense shock loads from material impact, and often a dusty, high-temperature environment. Any failure or loosening leads to immediate imbalance, catastrophic bearing failure, and expensive downtime. Maintaining an absolute zero-clearance, non-shifting fit is critical for the screen’s operational integrity.
INCURE WeldLock™ 365 Retaining Compound
For securing high-stress components on vibrating motor shafts—where maximum shear strength, high-temperature resistance, and absolute rigidity against cyclical fatigue are paramount—the WeldLock™ 365 provides the highest structural integrity. Its superior strength ensures the weights or hubs cannot shift, maintaining the exact timing and balance required for continuous vibration duty.
| Feature & Benefit | Technical Insight for Vibrating Motor Shafts | Conversion Value |
| Highest Strength (365) | Cures to an extremely high-shear strength, rigid plastic, providing maximum resistance to torsional slip and cyclical impact/vibration. | Zero Slippage: Guarantees absolute, 100%torque transmission and prevents fretting corrosion under constant hammering. |
| High Temperature Resistance | Withstands continuous operational temperatures up to 200∘C (392∘F), essential for components that generate friction heat and operate in hot environments. | End the Heat Threat: Ensures the bond remains rigid and strong under maximum thermal load. |
| Fills Close Clearance Gaps | Ideal for components with an interference or true close-tolerance slip fit (less than 0.05 mm diametral clearance). | Maximizes Concentricity: Converts the fit into an integrated component, optimizing balance and reducing destructive vibration. |
| High Vibration Dampening | The rigid polymer fills the entire gap, preventing metal-to-metal contact and actively dampening destructive vibration forces. | Extended Component Life: Reduces stress on the shaft, keyways, and motor bearings. |
Application Steps: Locking Vibrating Components for Maximum Lifespan
Preparation (Critical): Thoroughly clean both the component bore (e.g., eccentric weight bore) and the motor shaft surface. Remove all oil, grease, dirt, and residue. Use a powerful degreasing solvent (like acetone or industrial cleaner) and wipe until both metal surfaces are perfectly dry.
Application: Apply a continuous, liberal bead of WeldLock™ 365 evenly around the shaft surface. Alternatively, apply it to the inside circumference of the component bore. Ensure the compound completely covers the mating area.
Assembly: Slide or press the component onto the shaft. Ensure the component is seated correctly and wipe away any excess compound immediately.
Curing Time (Mandatory): Allow a full 24 hours for the compound to reach full cure strength before starting the motor or subjecting the screen to operational loads and vibration.
Alternative Consideration (Worn or Large Gaps): If the bore-to-shaft clearance is larger (up to 0.25 mm), use INCURE WeldLock™ 356 (Metallic Grey). This compound is formulated with metallic fillers to tolerate larger gaps while still providing high structural integrity.
Stop risking catastrophic motor failure and ensure your vibrating screen components are absolutely locked in place.
