Reverse gearbox for changing rotation direction of bevel gear

摘要

The gear box has at least three bevel gears (3-5) which are constantly engaged with each other. The first bevel gear (3) is fixed to a shaft (1). The second bevel gear (4) is freely movable on a second shaft (2), and the third bevel gear (5) acts as an intermediate gear which turns the second gear (4) in the opposite direction to the first gear (3). The gear box has a slidable and rotatable coupling (6) with bolts (17). There may be a slider (8) with fork (7) and guide rollers in the millings or bores of the bevel gears.
