Abstract (en)
[origin: EP2407833A1] The mechanism has a cam (39) and a wheel (33) connected together, so that revolution of the wheel has series of phase, in which the wheel drives the cam when the cam and actuating member cooperate to arm the member, another phase in which the member is disarmed and make a jump at the cam and a third phase, in which the cam is immobilized and the wheel continues to move to compensate the cam for leading the former phase of next revolution. A return spring (54) i.e. coaxial coil spring, acts between the cam and the wheel, and applies return torque to the wheel during third phase. An independent claim is also included for a clock movement comprising a clearance compensation mechanism.
