A right-angle gearbox (bevel gearbox) changes the direction of power transmission by 90 degrees, useful when the motor and driven shaft can’t be aligned in a straight line due to space or layout constraints.
Adding a planetary stage to a bevel gearbox increases torque capacity and load-sharing capability in the same compact right-angle footprint, compared to a standard bevel-only design.
Ratio ranges depend on the specific bevel and planetary stage combination selected — share your required input/output speed and torque for a configuration match.
Right-angle gear reducers are common in rolling mills, steel plant equipment, conveyor drives with perpendicular shaft layouts, and any equipment where a 90-degree power transmission path is needed within confined space.
Yes, GPRO engineers the bevel planetary gearbox with reinforced housings and bearing arrangements suited to the shock loads and duty cycles common in steel and rolling mill applications.
