Right angle gearboxes Z

right angle gears make the difference for the favourable relation between power/dimension and for the possibility of a silent and regular working, also at high speed.
One body piece in cast iron with all the external faces machined, the gears are Gleason and the bearings are overrated as well.
The modular construction of our Z right angle gears permits us to mount up to six input/output shafts (except ratio 1/1).
All these features place our products on top of this sector.
Ratio: Min 1/1 – Max 1/5
Torque (Nm): Min 8,9 – Max 2109
Power (Kw): Min 0,46 – Max 325

Rotoflexi

Rotoflexi coupling features all the characteristics of an elastic coupling and maintains construction simplicity and low cost.
Its main features are:

  • the possibility to replace the elastic element radially without remove and misalign the transmission, this increases the rapidity of intervention in case of replacement with saving of maintenance costs
  • high capacity to resist against shocks and overloads
  • high capacity to reduce vibrations between equipment
  • easy assembly and disassembly
  • electrical isolation between driver and driven side

Rotofluid K

Rotofluid is a mechanical component, designed to transmit torque from the drive (Motor ) to the driven part (machine), using oil as vector of force. Composed by a driving part (pump), a driven part (Turbine), mounted on main shaft and an alignment coupling.
Due to its operating the Rotofluid coupling, brings the following advantages to the transmission:

  • Easy start-up with soft acceleration of the driven component
  • Reduction of current peaks during start-up procedure
  • Torque limitation in case of overload
  • Protection of the driven machine in case of sudden stop

Rotomec

The hydromechanical coupling Rotomec contains all the characteristics of a hydraulic coupling, with the addition of a centrifugal coupling. The first stage acts as a starter (see hydraulic couplings); after the hydraulic stage, the centrifugal part operates as a clutch, eliminating the slip between the driving motor and driven machine.

Skew bevel helical gearboxes

The low power bevel helical gearbox range, which was unavailable until today, is now ready by means of a brand new type of gearbox,
for which mechanical system S.T.M. has been given the copyright.
This very new and innovative gearbox relies on helical gears with oblique shafts and puts together in a single conception the economical cost (typical of worm gearboxes) and high efficiency (typical of bevel helical gearboxes with right angle pair).
The 3 sizes being planned cover a torque range ranging from 100 Nm to 250 Nm and will supply every application: the best product to optimise ratio torque/cost.

Worm gearboxes R

The company has decided to update its main product by adding three innovative principles: two are technical and one is commercial.
All aluminium components 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.
New ideas to approach a bigger market together: first, since 1987, with the patent of the torque limiter built inside our standard gearbox.
Ratio: Min 1/5 – Max 1/100
Torque (Nm): Min 10 – Max 2103
Power (Kw): Min 0,01 – Max 31,61

Worm gearboxes u

The body has been designed in order to optimize the heat dissipation and to simplify the cleaning of it, even in the most difficult environmental conditions.Ratio: Min 1/7 – Max 1/100
Torque (Nm): Min 26 – Max 638
Power (Kw): Min 0,04 – Max 10,01

worm gearboxes W

Their heavy-duty and reliable structure can rely on modular accessories availability, such as output shaft, torque arm and protection cover.
The gearbox cubic shape ensures a fixing universality and allows a great modularity and an easy management of the components in stock.
Sizes from 25 to 90 are in aluminum, while sizes from 110 to 150 are in cast iron and all of them are blue painted.
Ratio: Min 1/7.5 – Max 1/100
Torque (Nm): Min 10 – Max 1550
Power (Kw): Min 0,04 – Max 25,5
