The invention discloses a device and a method for measuring angular displacement of an engagement sleeve of a mechanical transmission in real time, belonging to the technical field of mechanical transmission measurement. The device is configured to match a film-encoder with an encoder bushing, and then is connected with a flange; the flange is connected to an output shaft of the mechanical transmission; a measuring device housing is connected to the flange by bearings; and an AB-phase sensor and a Z-phase sensor are fixed around the inside of the measuring device housing by curved small pieces, and an angle between them is 90 degree or 180 degree. The method comprises the following steps of: keeping the film-encoder in the middle of the AB-phase sensor and the Z-phase sensor; transmittingthe film-encoder during rotating through the AB-phase sensor and the Z-phase sensor; converting a collected pulse signal into a digital signal in a peripheral circuit on the housing; and mathematically converting with a turni
