Keep Drivetrains Running with 24/7 Gearbox Condition Monitoring
Find fault patterns before they find your team with continuous gearbox monitoring.
For Gearboxes that Keep Things Running
Gearbox failures are incredibly disruptive. AssetWatch monitors for gearbox distress signals, so your team isn’t caught reacting to a failure that had weeks of warning.
Reduce Unexpected Downtime
Continuous condition monitoring for gearboxes catches developing fault signatures ahead of failure, so teams have time to repair proactively instead of reactively.
Lower Maintenance Costs & Overtime
With the right data in hand early enough, parts get ordered, downtime gets scheduled, and emergency labor is no longer the default response to a gearbox problem.
Extend Asset Life & Stabilize Production
Through gearbox predictive maintenance, issues get flagged—and repaired—at asset-level before they create problems through the whole drivetrain.
Gearbox Conditions We Monitor
Gearboxes have faults that appear in analysis data long before they cause mechanical harm. AssetWatch software monitors for the mechanical fault signatures that matter most on your gearbox equipment:
Gear Wear
Gear wear is gradual — tooth surfaces erode slowly, leaving a trail in both the vibration signature and the oil. Vibration analysis tracks the progression through gear mesh frequency changes, while oil analysis monitors the buildup of metallic particles as the wear advances.
Gear Tooth Damage
Cracked or broken gear teeth generate sharp impacts at the shaft's running speed — a pattern that stands out clearly in vibration analysis. Oil analysis runs alongside it, with a spike in metallic particle content often confirming what the vibration data already suspects.
Oil Analysis (high particle count)
Elevated metallic and non-metallic particle counts flagged before wear rates accelerate to failure-level conditions.
Bearing Wear and Defects
Bearing failures start below the surface — lubricant breakdown and sub-surface fatigue develop long before heat or noise appear. Vibration and oil analysis flag it weeks ahead, when a planned repair is still an option.
Shaft misalignment
A bent shaft — whether from a rotor bow, excessive load, or mechanical damage — produces a vibration signature that mimics misalignment but doesn't improve with realignment. Vibration analysis identifies the condition so the right diagnosis gets made.
Mechanical Looseness
Loose hold-down bolts, worn bearing fits, and cracked or defective bases allow the machine to move in ways it shouldn't. Vibration analysis picks up the characteristic response — directional vibration and phase shifts that point to where the structure has lost its rigidity.
Lubricant Degradation
Oil breaks down over time — viscosity drops, additives deplete, and the protective film between moving surfaces gets thinner. Oil analysis tracks the degradation continuously so a fluid change happens on schedule, not after the damage is already done.
Wear particle detection
Metallic wear particles in oil are a direct signal that something inside the machine is breaking down — bearings, gears, or other contact surfaces generating debris under load. Oil analysis quantifies the particle concentration and type, giving a clear picture of where the wear is happening and how fast it's progressing.
Rotating Component Imbalance
Uneven mass distribution identified by characteristic vibration patterns at running speed.
Coupling and drive train issues
Worn coupling elements, loose keyways, or dry gear couplings put stress on every bearing and shaft on both sides of the drive. Vibration analysis picks up harmonics of turning speed and impacting in the waveform to gauge the severity of the failure.
Resonance and Structural Vibration
Resonance occurs when a machine's operating speed excites the natural frequency of a structure, producing high vibration in one direction that doesn't respond to balancing or alignment. Vibration analysis identifies the condition and separates it from other fault types so the right fix — speed adjustment, added mass, or stiffening — gets applied.
Gearbox maintenance software ensures these signatures get flagged and that your team has a recommended action waiting when they appear.
How AssetWatch Works for Gearboxes
Most gearbox failures are avoidable. AssetWatch offers continuous AI-powered monitoring and expert human review to prevent line shutdowns—whether you’re managing a single line or multiple operations.
Sensors Installed on Critical Gearbox Points
Continuous Vibration wireless sensors go on at key measurement points, typically input and output bearing housings, gear mesh measurement points, and other high-risk locations—all without the need to shut down production.
Continuous Data Collection & Trending
Sensors run 24/7, building an asset-specific baseline over time. Changes and anomalies show up in trending data long ahead of any audible symptoms or alarm thresholds.
AI Analytics Identify Emerging Patterns
The AssetWatch platform runs automated detection against known gearbox failure signatures, including harmonics, defect frequencies, and looseness. Your team gets context on what’s happening and why.
Expert Validation & Prescriptive Recommendations
A dedicated condition monitoring engineer (CME) reviews every flagged finding before it reaches your team. The result is a confirmed fault, a priority level, and a specific recommended action.
Asset Saves in the Field
AssetWatch caught severe wear and contamination in an extruder gearbox's lubricant, and the fix prevented 336 hours of downtime.
Vibration analysis caught coupling wear at a gearbox input before it caused a failure, letting the customer replace it and restart the same night.
Rising vibration and impact frequency flagged a bearing defect on a separator gearbox's intermediate shaft, and replacing it during a planned outage saved $35,520.
Frequently Asked Questions
Gearbox vibration monitoring can identify a wide range of developing faults, such as:
- Gear tooth wear
- Mesh defects
- Imbalances
- Misalignment
- Mechanical looseness
- Coupling issues
AssetWatch tracks those patterns continuously, catching shifts in the signature before they become audible or visible problems.
Gearbox vibration monitoring is the core condition monitoring method for detecting most mechanical gearbox faults early. Gearbox condition monitoring refers to the broader practice, typically adding oil analysis to catch lubrication degradation, contamination, and wear particles that vibration alone doesn't always surface.
In addition to oil analysis, AssetWatch offers both continuous vibration monitoring and route-based vibration monitoring, depending on criticality.
Gearbox predictive maintenance shifts the trigger for action from failure to trend. Instead of waiting for a symptom, your team acts when the data shows a developing fault. Gearbox maintenance software gives teams real, validated data early enough to plan the repair, source the parts, and minimize production impact.
For gearboxes that drive critical production processes, continuous monitoring is the stronger option. Issues like gear mesh defects and bearing damage can progress faster than a monthly route allows for. Route-based vibration works for lower criticality assets where the consequences of a missed interval are manageable. Many facilities tier their monitoring approach by asset criticality.
This depends on what data shows, and this is exactly what a CME review provides. For example, a rising gear mesh harmonic with stable bearing signatures might warrant monitoring and a lubrication check. Issues like bearing defect frequency trending upward alongside looseness indicators likely need a planned inspection and parts on order.
With AssetWatch, your team gains dedicated CMEs to deliver recommendations triggered specifically by what analytics reveal.
