Abstract (en)

[origin: WO2022018337A1] A transmission housing (1) which can be coupled to the drive shaft (21) of an electric motor (20) to form a gearbox (22), the transmission housing (1) comprising a housing body (2) defining a cavity (4), and housed at least partially inside the cavity (4) - a rotary drive member (5), - an output shaft (6) and, - a device (7) for transmitting the rotational movement of the rotary drive member (5) to the output shaft (6), characterised in that the rotary drive member (5) is supported inside the cavity (4) of the housing body (2) by one or more guide members (8) and comprises a wall (9) and two coaxial helical teeth (10) created from a single part with the wall (9) and arranged on either side of the wall (9), the helical teeth (10) being configured to generate axial forces in opposite directions.
