Exhibition Show Planning for 2008

During the year 2008, Servomech will be on 3 different exhibition shows all over Europe. Each of them is focused on a specific market sector.

.: 3 - 5 April 2008
Motek Italy Parma (Italy)

Italian exhibition specifically conceived for assembling, joining and handling technology.

.: 12 - 14 June 2008
Intersolar 2008 Munich (Germany)

During the InterSolar 2008 show which will be held in Munich from 12. to 14. of June 2008, Servomech will be pleased to introduce you our latest news on linear actuators for photovoltaic tracking systems. Thanks to their peculiar design, construction materials and inner features the Servomech linear actuators for PV tracking systems are successfully applied in several installations around the world.
Servomech linear actuators for solar trackers are conceived and engineered to work outdoor in hostile environments. Robust products, designed and manufactured for strong wind conditions, they are produced for a long operational life with high reliability.
Different sizes available, all self-locking, with dynamic load capacity up to 100 kN. Linear speeds from 1 mm/s up to 7 mm/s and stroke lengths up to 1.500 mm. Available with either AC or DC motors. Option: self enclosed limit switches and positioning control via rotative potentiometer or incremental bi-directional encoder.

Come to see us at Hall B5 - Booth no. 382.
For more information please contact us at info@servomech.com.

.: 24 - 26 September 2008
Power Expo Zaragoza (Spain)

Spanish show focused on sustainable and efficient energy production with particular interest to photovoltaic technology.

Trapezoidal screw 12m long in the rocket Ariane 5 assembly

Ariane 5 is a rocket capable of lifting a payload of 6,200 kg in a geo-stationary orbit (GTO). It is 59 m high, has a body diameter of 5.9 m and weighs 777,000 kg (777 Tons). The machining operations of the various rocket stages require the creation of 3 platforms that allow both the lifting and the machining of the stage within the platform itself. Each platform is capable of lifting 50,000 kg (50 Tons), inclusive of its own weight, at a linear speed of 0.5m/min and a stroke of 11 m.

For this application Servomech has supplied MA350 jack type A with 3:32 reduction ratio, acme screw lead pitch 100x16 (Tr 100x16) 12 m long. The screw jacks are fixed on the platforms using a trunnion-mount to allow a single degree of freedom. The screw used is connected to the top mounting structure through a clevis with the axis parallel to the trunnions. The system is suspended with the jacks connected to the moving platform and the screw stationary. A further redundancy is accomplished using a safety nut. Each jack has an actuator feedback to allow synchronous motion using the electric shaft principle. The platform configuration does not allow mechanical connections amongst the jacks thus each jack is individually motorized with a vector drive motor of 7.5 kW.

The 12 m long screws are machined from ground bar by metal removal using a whirling process. This process is performed at Servomech plant using 6-axis CNC equipment produced by a German company.
