The Bonfiglioli Trasmital 300 series of planetary gearboxes are the real workhorses of heavy duty tasks that demand high torque.
We have specified them for a myriad of applications, from heavy conveying right through to ultra-high ratio mixing. Each and every time, they have performed flawlessly.
Planetary Gearbox Design Considerations
One of the primary things to consider when specifying a planetary gearbox into a design, is the thermal capacity of the unit. For most applications, the torque load is not a worry, but the thermal limitations are reached more easily. Planetary gearbox manufacturers have mitigated against this issue, designing external oil coolers that can help to increase the overall unit capacity.
These thermal limitations are compounded in high ambient conditions, so extra attention must be paid when operating conditions in temperatures above 40°.
Planetary gearboxes are also very flexible for a number of reasons:
– they can be fitted in combination with either worm gear units or bevel-helicals to increase the speed range offered
– they can be either flange, foot or shaft mounted (or combinations of these options)
– output options include keyed output shaft, splined male shaft, splined hollow shaft, and hollow shaft with shrink disc
– inputs can include IEC motors, integral motors, male shaft input as well as hydraulic motor input
With housings made from ductile cast iron, inner parts coupled through splined connections (not keys) and heavy duty tapered roller bearings, the Trasmital range of planetary reducers offers both high torque density and high efficiency.
