Gearbox design smashes engineering
barriers
Considered a breakthrough in the world of industrial transmissions, a gearbox offers a service life of greater than 50,000 hours - 30,000 more than the industry average.

Packaging improvement prevents bearing damage
A versatile, robust and environmentally friendly packaging solution for the transportation of large-size bearings affords easier and safer handling and superior protection.
Giving angular contact ball bearings longer life
By modifying the geometry of the raceways and changing the manufacturing process, the axial load carrying capacity of angular contact ball bearings has been increased and lifespans extended.
As well as slashing both weight and volume, it offers a service life of greater than 50,000 hours - 30,000 more than the industry average.
Basing its design brief on compactness and reliability - the two primary customer demands relating to gearboxes, SKF applied its considerable engineering know how - in combination with expertise from its industrial partners - to prove that it is possible to surpass established engineering norms.
SKF does not intend to manufacture industrial gearboxes, instead it used this exercise as a demonstration of how inter-departmental and inter-company research, knowledge and cooperation can be applied to achieve a common goal.

In the plastics and textile industries, the maintenance of clip chains is a major production uptime consideration, so a specialist refurbishment service has been set up.
Non-contact thermometer takes the heat
A lightweight and compact, non-contact, thermometer is designed to measure the temperature of hot, hazardous or hard-to-reach objects, without contaminating or damaging surfaces.
In the design study, SKF Engineering Consultancy Services, through the Orpheus calculation tool, contributed to the static and dynamic modelling of the gearbox as a "system".
This gave, in addition to the results pertaining to bearing behaviour, reliable information regarding how to optimise the performance of other components.
SKF also chose partners to provide expertise in areas outside its own core competencies.
The Fiat Research Centre cooperated in the study of issues relating to the gears, in order to create optimum gear profiles.
Optimum lubrication has been calculated and guaranteed through the contribution of the global lubricant company Mobil.
Nine bearings were used - all from the new SKF Explorer range: four spherical roller bearings, three cylindrical roller bearings and two angular contact ball bearings.
It is thanks to the SKF Explorer bearing that the SKF 18K gearbox has been designed for a service life exceeding 50,000 hours.
The prototype also provided the opportunity to try out the new SKF standard industrial seals.
Based on an original design, they take advantage of a new compound, created for this application.
Finally, SKF Mechatronics developed an integrated monitoring system to guarantee reliability.
It uses 10 sensors, working together: five accelerometers, two position sensors and sensors for temperature, torque and speed.
With this prototype, SKF has ably demonstrated that it is possible to develop new value-adding products in very demanding and competitive markets; markets where product differentiation can be difficult and where all too often the component price is considered more important than the product quality or ultimate value.
