Driving solutions

Critical speeds analysis on HS shaft (Campbell diagram)

BCSA GEAR offers you unique solutions matching your specific needs.

Its design department has a real know-how and a great experience in working out those solutions.
Our engineering team can count in particular on their dynamic behavior analysis for HS lines knowledge.

This knowledge allows us to design new systems and to ensure their proper functioning.

Some of our works:

Gearbox for balancing machines.

Shifting speeds machines for rotor balancing systems:

We have already designed about thirty devices of this kind. Their specificities are the heavy loads driving meaning high torques and high powers (Up to 10mW and 115 000Nm). Meanwhile they permit high speeds driving (Up to 30 0000 rpm).
Their design allows a speed shifting on the same HS shaft.
These speeds shifting can be manual or remote controlled operated by an electric jack.
Auxiliary drives are integrated to permit the step by step turbine rotation.

High speed bearings used as an interface with a vacuum enclosure:

HSB machines on test

Because of the high speed air friction, vacuum installation are commonly used for testing purposes. We design bearings able to ensure the sealing with the vacuum area while transmitting the required torque at high speed. We also integrate constraints such as axial and radial load created by the application or the axial play facilitating the installation.

Flywheels with integrated torquemeters:

As a part of breaking system tests we designed machines with flywheels. Those reducers allow the choice among one or several inertia on the same shaft. Moreover as other projects, we planned the torquemeter integration. The brakes are directly fixed on our casing and a bearing protects the machine against the braking process guaranteeing the installation longevity.

Innovative protections

Bearings on cushioning pad

Most of our gearboxes allows our customers to perform tests. Some of these tests are rough for the mechanic, mainly for the tested device but also the driving machines in particular in destructive tests.
Thus we have looked for protecting our gearboxes against these collateral effects.
Here under our gearbox is equipped with bearings protections against the fatigue test vibrations.
