<p>A differential speed reducer (11) with an input shaft (14) connected to two spur gears (18 and 20). An inverter gear (22) is engaged with the first spur gear (18). The second spur gear (20) and the inverter gear (22) drive a third (26) and fourth spur gear (28) which are freely rotatable on an output shaft (16). A bevel gear (34 or 36) is attached to each of the third (26) and fourth (28) gears. A pinion gear (38) rotates between the bevel gears (34 and 36) and as it orbits, turns the output shaft (16).</p> |
