Helical Geared Units with Hollow Output Shaft
The TT Series gearboxes are helical-geared, two-staged, output-shaft-mounted units with a hollow output shaft and a monoblock housing. All axes are machined in a single operation to achieve exact tolerances. The gears are arranged to optimize minimum housing volume. So that it was possible to get higher torque values in smaller housing volumes.
Housing material is GG20 cast iron and gears are made of high-quality case-hardened steel. Material properties and manufacturing processes are continually controlled. The TT series gearboxes have hollow shafts and a compact housing so that they can be mounted in smaller spaces. They are mounted to the machine using torque support arms.
Connection holes on the gear units are used for mounting. Supplied without motor, the units are belt-driven. When selecting gear units the overhung load acting on the input shaft must be checked against the permissible values on the performance tables according to input speed.
