Understanding Gearbox Repairs: Common Issues and How to Prevent Them
Industrial gearboxes are essential to the operation of countless industries, from manufacturing and mining to power generation and processing facilities. At Hanco, Ltd., we specialize in comprehensive gearbox repair and gearbox service for all makes and models, including Sumitomo gearbox repair and Hansen Industrial Gearbox repair. With over 50 years of experience and state-of-the-art facilities in Pennsylvania and Kentucky, we understand the wear and tear gear boxes endure and the critical importance of keeping them in peak condition.
Common Gearbox Issues We See
Gear boxes are complex systems subjected to significant mechanical stress, which makes them susceptible to several common problems. These are the most frequent issues our technicians encounter:
Gear Wear and Pitting
Over time, metal-on-metal contact causes surface fatigue, leading to wear patterns and pitting. This typically results from insufficient lubrication, improper alignment, or contaminated oil. In Sumitomo repair and Hansen gearbox repair, this is one of the most common failure modes.
Bearing Failure
Bearings play avital role in supporting rotating shafts. Excessive load, vibration, or lubrication failure can cause them to overheat, seize, or disintegrate. We often detect bearing issues during our diagnostic evaluations, especially during emergency gearbox repair and service calls.
Seal Leaks
Oil leaks not only reduce lubrication but also introduce contaminants into the system. Worn seals or improper installation can result in leaks that eventually damage internal components.
Misalignment and Shaft Deformation
Improper installation or thermal expansion can lead to misaligned shafts, which puts undue stress on gears and bearings. This is a leading cause of early gearbox failure.
Overheating
High operating temperatures accelerate oil degradation and metal fatigue. We use thermal imaging during inspections to identify heat-related issues before they cause costly failures.
How to Prevent Gearbox Failures
While some wear is inevitable, many gearbox issues can be avoided with proper care and proactive maintenance. Here’s how Hanco helps clients extend gearbox life and reduce downtime:
Routine Gearbox Service and Inspections
Regular inspections can catch developing problems before they turn into failures. At Hanco, our technicians use vibration analysis, oil sampling, and thermal imaging to identify early warning signs. Whether it’s part of a scheduled Sumitomo service or a broader facility maintenance plan, inspections are your first line of defense.
Proper Lubrication Practices
Using the right type and amount of lubricant—and replacing it at regular intervals—is crucial. Our gearbox service includes checking lubricant condition and ensuring it meets OEM specifications for systems like Sumitomo and Hansen gearboxes.
Timely Repairs and Rebuilds
When problems are detected, prompt repair is key to preventing further damage. Hanco’s ability to manufacture replacement components in-house allows us to offer fast turnaround, especially for critical needs like emergency gearbox repair and service.
Expert Installation and Alignment
We support clients with installation services that ensure proper shaft alignment and torque settings. Misalignment is a preventable issue that, if ignored, can dramatically reduce gearbox life.
Custom Upgrades and Modernization
Sometimes, the best long-term solution is to upgrade aging components. Our team can modernize outdated gearboxes to increase efficiency and reliability while maintaining compatibility with your existing systems.
