GEARBOX EFFICIENCY CALCULATION

The engine: I didn't find the rpm of the motor, so I will use the rpm of a simular engine I found here http://www2.conrad.be/goto.php?artikel=129024

550Watt
1500 rpm

The energy conversion efficiency of a gear is 98% (this is a mean value by experience)



The Formulas

The efficiency of the gearbox is 88,58%

The max torque is 233 Nm

The max Force is 3740 N

Every axis has his own speed, torque and force.

#The blender needs a high speed, less torque and force

#A mill, needs a low speed, high torque and force

PARTS # GEAR BOX

This is the gearbox, 2 parts fix together. It was filled with greas (there's a hole to inject the greas) and glued with silicone.

PARTS # PLANET HUB COVER

The planet hub cover is chromed. It connects the axis of the gears with the beater.
