Our Drive Technology Expertises

Gearbox Machine Diagnostics

Machine Diagnostics

Our team of inspection engineers is one of the most experienced and well educated in Western Europe.

We have done many inspections and Failure root cause analyses in many industrial, maritime and wind industries.

Further our department has knowledge on
- Condition based maintenance
- Equipment health management
- Torque and power measurements
Inspection of gearboxes

Onsite gearbox inspection, repair, alignment and commissioning

Our service engineers have besides their tremendous commitment and flexibility, also a great knowledge of gearboxes in their specific environment. Often the environment is the basis for earlier failure. In addition to onsite inspections and assembly, we can execute the following:
-Field trim balancing
-Geometrical measurements
-Thermal growth studies
-Torque and power measurements
 
Onsite gear measurement

Onsite gear measurement

We have an portable 6 axes gear measurement tool. With this measurement tool we can check and measure the profiles on-site of unknown gears.

For our customers, this has the advantage that we can measure components in the gearbox. Vulnerable parts need no longer to be transported with all the risks. Gearboxes should be opened just for an short lead-time. Existing heavy gears that should be replaced, doesn't need to be transported with high costs.
Engineering of gearboxes

Engineering

Our engineering department focuses on all issues of gearboxes.

A broad practical experience combined with modern equipment makes us distinctive.

Our department consists of employees with an average of 15 years experience in gearboxes of many brands for many applications, such as wind, the dredging industry, shipping, energy production and container and bulk handling.
 
Machining

Machining of gears, gearbox housings and other related parts

Our company has an machining department with about 35 employees. From 2009, we have made significant investments in new machinery, including a Niles for grinding the gears. Furthermore, we have started the production of gears on 5-axis milling machines. Our production portfolio in terms of gearboxes looks therefore as follows:
-housings
-white-metal bearings
-gears
-shafts
Inspection and repair of gearboxes in our workshop

Inspection and repair of gearboxes in our workshop

From 2009 we have trained a group of 20 engineers, which work as well on site as our workshop. Our main tasks are:
-complete inspection,
-troubleshooting
-reporting and
assembly.

In 2016 we will expand our company with a specially equipped assembly hall.
 
Test run of gearboxes

Test run of gearboxes all our gearboxes

All our gearboxes are subjected to a test to our test stand.

GBS Gearbox Services develops a triple-500 kW-Oil-Purity test facility, which will be ready mid 2016.
Machining

Laser Cladding

In the cabin, we can roughly handle big size of objects:
  • long spindles having a length up to 8 meters and an outside diameter of 3-4 meters
  • other objects which we can be placed on a rotary table with a diameter of 3-4 meters and a height of 3 meters
    •
     
    Zero leakage Program for gearboxes

    Zero leakage program

    We are willing to determine de common cause of failure and to find an solution to reduce the failure mode of oil-gaskets and -seals.

    We will do research to find the root cause of different leakages and provide professional advice to our customers.

    Maintenance Management of gearboxes

    Maintenance Management of gearboxes

    At this moment we have custom software for capturing our inspections and repairs. For our larger clients we are currently developing a management system for all their gearboxes, allowing current status, required actions and history are transparant.
     

     

    Condition of the Gearbox Something is clearly wrong

    (mostly damage)    		 Something seems to be wrong
    but what?
    (gearbox is running)    		 Nothing seems to be wrong

    just check!
    Diagnostics
    On site trouble shooting
    Machinery health or condition inspections
    By means of video scope, vibration measurement,
    Torque measurement, Thermal pictures and other type of inspections we determine the condition of the gearbox and the more important the cause of arising damage. Our goal is to determine the existing life-time and/or the exact cause of the damage, to be able to develop with our engineering department an modification, so further damage can never again happen.
