TG (Torque Gearbox) or so called semi elastic suspensions were designed specially for free standing gearboxes and/or close coupled high speed engines/gearboxes where the mounts have to absorb the torque reaction in combination with full propeller thrust.
The TG mountings provide sufficient load capacity combined with long service life. Although originally designed for gearboxes and close coupled engines/gearboxes, the mount arrangements are particularly versatile and can be used for many other applications.
The characteristics of the TG mounts are provided by inner and outer precision metal sleeves, which are strongly bonded together by vulcanization between rubber and metal surfaces. The TG mounts damp radial and axial vibrations and withstand torsion and cardanic deflection. Load ranges go up to 300 kN per mounting. The standard rubber elements are manufactured in 60 shore A rubber mix, but are also available in other compounds upon request.
