Our experienced service engineers support commissioning and running-in of plants and carry out regular inspections across the entire lifetime of large gear drives-helping you reduce unplanned downtime and extend component life.
Our core competencies include inspection, maintenance and repair of large open gears, with a strong focus on heavy-duty industrial applications such as the cement industry. We combine field measurement, lubrication know-how and practical repair methods to keep gear drives operating reliably.
We inspect the lubrication system to confirm correct installation and reliable operation. This includes checking that lubricant lines are tight, correctly routed and not bent; verifying that the spray/dispensing arrangement is installed correctly to avoid overheating; and assessing cleanliness of containers and the surrounding area to reduce contamination risk. We highlight practical improvements to support consistent lubrication and lower lubricant consumption (application-dependent).
We perform vibration measurements using calibrated electronic tools to capture precise values and identify early signs of misalignment, imbalance or mechanical defects. Trend-based measurements support condition monitoring and help plan corrective actions before damage escalates.
We measure temperatures at defined points to identify hot spots and uneven load distribution. As a general guideline for acceptable temperature differences:
We examine concrete foundations for cracks and structural changes that may indicate extraordinary loads or movement. Foundation condition can affect pinion bearings and alignment-and therefore the stability of the entire drive unit.
We assess the drive geometry and the operating condition of the pinion and gear rim to verify true running and load distribution. This helps identify alignment issues, runout, or mechanical influences that can accelerate tooth flank wear.
Tooth flank damage is often connected to one or more of the following factors:
Mechanical treatment of tooth flanks focuses on controlled material removal to restore the original tooth profile and reduce progressive damage. Work steps are documented and aligned with the condition of the gear and the agreed service scope.
The method is based on systematic surface correction. Deviations in tooth shape, material distortions, loose particles, plastic deformation and welding folds can be addressed-first with rough grinding, then with fine grinding-to restore a more stable contact pattern.
Tell us your gear drive type, operating hours, symptoms (noise, vibration, temperature rise), lubrication method and any recent changes. If you have measurement records or previous inspection reports, include them. We will propose the best-fit inspection scope and service plan.
