There have been several developments in the field of industrial gearboxes that offer designers improved options in terms of performance and efficiency.
Among these is a new range of right-angled planetary gearboxes that are now available from Motor Technology for a wide range of industrial applications. Manufactured by Italian firm, Tramec, the TEP range is based on the company’s long-established EP range of general-purpose planetary gearboxes.
Right-angled gearboxes are frequently used where there are space constraints on a machine, often machines with high axis counts, such as slitters and winders, printing and packaging machines, handling and robotics, etc.
Currently available in four frame sizes, 55, 75, 90, and 120, in one and two-stage configurations. Single-stage versions offer ratios from 3:1 to 10:1, and two-stage versions offer rates from 12:1 to 100:1.
Backlash ranges from 12-17 arcminutes for the single-stage and 15-20 arcminutes for the two-stage versions. Gearbox efficiency is 94% for the single-stage type and 91% for the two-stage.
The gearboxes also perform well in terms of noise generated during operation with levels between 65 to 70dB at 3000rpm input speed. Gearbox output torque is up to 180Nm nominal, 290Nm peak, and with an E-Stop torque of 600Nm.
