STM & GSM

 

Year 1976 is not only a date for S.T.M. It represents the starting of a small company that is today an important reference point in the mechanical transmission field, thanks to the entrepreneurial capabilities (from foundation members Girotti Tiziano, Vignoli Altero and Lucchini Giuseppe), expertise and firm commitment of the promoting partners.
S.T.M. over 90' has turned from a craftsmanlike expression into a big industrial company specialised in the design and manufacturing of speed reducers.
S.T.M. is nowadays well known in national and international markets in which has reached a respectful position.

In 1998 S.T.M. achieved ISO 9001 Certification, with the aim to grant a good quality system for the different market needs.
Today S.T.M., using modern design systems and high-tech production machinery (working centres, gear cutters, and sophisticated grinding centres), can offer a wide range of speed reducers, electric motors, mechanical and electronic variators.

IN-LINE A

The design of this range of gear units is based on one body piece casting giving increased rigidity.
This allows to apply high loads without risks of deformation which might negatively affect technical performances.
The particular internal shape of the body directs the oil flow in a way to reach all moving parts while reducing noise levels and improving sealing tightness.
Another piece of news is the modular attachable output flange to provide excellent versatility even in multiple applications.

The company has decided to update main product by adding three innovative principles : two technical and one commercial. All components in aluminium are die casted (from size 28 to size 70) to increase resistance to torsional and structure flexibility.ZI teething profile (section and involute) has been adopted to increase efficiency and silentness.
Finally, a modular attachable output flange (FL) has been adopted to increase flexibility.

MECHANICAL VARIATOR V

MECHANICAL VARIATOR V

In view of carrying out a costant product development, expecially on those products where no technical innovations are due, we have
managed to increase the efficiency of our mechanical speed variators by reducing the heat dissipation during operation.
This has all been possible by working out an additional operation on the components after grinding : the finishing by chemically accelerated vibrations.
This new process makes surfaces uncomparably good in reducing friction, wearness as well as contact fatigue and dynamics.
The main buildings and functional features of this product, that increase its versatility, are the integral motor flange to the housing and the completely modular structure for what concern the output flange and the feet: these features allow to reduce the dimensions and the stock warehouse improving and increasing the flexibility and overall economicity.
