Abstract

See full text

A gear transmission includes a first helical-cut gearwheel (1) and a second helical-cut gearwheel (2) engaged for transmitting torques in different directions. The first gearwheel (1) and the second gearwheel (2) each include corresponding ring-shaped thrust collars (4, 5), and corresponding thrust collars (4, 5) each form a race (8, 9, 10, 11) having an overlap region. A first race (8) and a second race (9) form an overlap region for traction torques, and a third race (10) and a fourth race (11) form an overlap region for overrun torques. Each overlap region includes a contact surface or a contact point (14, 15), and each contact point (14, 15) is situated on a contact circle diameter (16, 17). The contact surfaces or contact points (8, 9) for traction torques and the contact surfaces or contact points (10, 11) for overrun torques are radially offset.
