Reducing the production cost of renewable energy is possible

Reducing the production cost of renewable energy is possible

Reducing the production cost of renewable energy is a priority in order to favour its commercial penetration. This can only be achieved through a real technological enhancement that allows reducing costs for the building of plants as well as improving their efficiency.
Improving the features of the turbine axle is certainly an effective strategy. Read more

Irreversible Coupling

Irreversible Coupling

The Girotto irreversible coupling is a mechanical device which comprises a motor element (input) and a driven element (output), both movable with respect to a fixed structure, usually a frame. The main features of the irreversible coupling are the large transmission capacity of torque and high sensitivity and accuracy of positioning.
The fields of application are varied, can be applied in any type of mechanism that needs a command irreversible and very precise.

Limited-Slip Differentials

Limited-Slip Differentials

The Torsen differential is used a lot for the great reliability and lack of maintenance during the operating life, due to the fact that there are no inside friction elements; the only it’s obvious flaw is given by the overall dimensions that are more of the locking differentials to strip and the cost that is significantly higher than conventional differentials.
