Abstract (en)
[origin: CN107667234A] The device comprises a shaft 4, a notched mobile member - for example a wheel 1 - and at least three arms 2.1, 2.2, 2.3 that together transmit movement between the shaft 4 and the mobile member. Eacharm is hinged to two eccentric bearings 3, 3' that hold same parallel to said arm, regardless of the rotational angle of the shaft 4 with which they rotate synchronously. Each arm engages with the notches of the wheel 1 during at least a portion of the cyclic motion of same, by means of at least one tooth 7 of the arm, in such a way as to ensure mutual displacement. The bearings 3, 3' are arrangedsuch that at least one of the arms engages with the mobile member, regardless of the rotational angle of the shaft 4. Said device can be used for producing low-clearance speed reducers.
