| Gears, Shafts, Bearings & Housings |
Duty cycle measurements in the field tell us how the transmissions are loaded for a specific machine and application (wheel loaders, telescopic boom handlers, lift trucks...). These load spectra are used to predict the life of gears and bearings.
The calculations include the total behaviour of the system (influences of gear mesh deflections, shaft deflections, bearing deformations, housings...)
The gear geometry is optimised for manufacturability and load stresses. Applying microtopology modifications is an advanced technique to optimise contact pattern and reduces transmission error (dynamic behaviour leading to noise)
Bearings are selected based on load types, life requirements and assembly possibilities. Full engineering co-operation of major bearing suppliers helps optimising the design for cost.
Material and heat treatment are selected based on the design and manufacturing requirements.
The calculations are validated by running accelerated load tests in our test lab. Failure analysis is an important part of the process used to determine the real limits of the components. |
