    In a drive coupling arrangement, a first gear wheel 16 meshes both with a second gear wheel 4 and a third gear wheel 6. The second gear wheel 4 has an odd number of internal teeth 8. The third gear wheel 6 carries two resiliently biassed detents 7, controlled by a lever 10 and electromagnetically operated catch 12. Only a segment of the third gear wheel 6 meshes with the first gear wheel 4. Upon actuating the lever 10, one of the detents 7 engages the internal teeth 8, such that the third gear wheel 6 is entrained by the continuously driven second gear wheel 4. Thereafter, the third gear wheel 6 meshes with, and is driven by the first gear wheel 16. When the third gear wheel 6 has completed one revolution, the detents 7 are released via the lever 10, and the third gear wheel 6 remains in a rest position until the lever 10 is again actuated. …<??>The invention is particularly applicable to the drive coupling of a transport mechanism 2, and a control drum 1 for a printing mechanism, for a postal franking machine. …<IMAGE>…

    The invention relates to mechanical engineering, and can be used in franking machines.
    A free-wheeling ratchet clutch is known, which contains a ratchet with an odd number of teeth on the ring gear fixed on the axle, two clamps and a control device connected to the clamp tl. However, the known clutch does not provide a free-slip clutch.
    The purpose of the invention is to improve the accuracy of work.
    The delivered target is achieved in that the free-wheeling ratchet clutch for a franking machine, containing a ratchet with an odd number of teeth on a gear ring mounted on an axis, two Clamps and a control device connected to the lock, is provided with an axial sleeve coaxially mounted with a ratchet mounted on it is opposite to the ratchet by a ratchet wheel, on the part of the outer surface of which there is a tooth, the control device is made in the form of an electromagnetically controlled doggie and a pivot arm with pads, under Spring-loaded spring twist and placed on the axial sleeve at the end of the ratchet wheel, clamps mounted on the ratchet wheel are fitted with compression springs that press clamps onto the tooth of the ring gear, which is mounted on the inner surface of the ratchet, while the pivot arm legs are spring-loaded The torsion is tightened to the fixatives.
    FIG. 1 shows a drive mechanism with a described freewheel ratchet; in fig. 2 - gearing between the pinion gear and the ratchet wheel.
    The ratchet freewheel is kinematically connected to the drive 1 via gears and the xpsnoi wheel ij mounted on the ratchet 6. The ratchet 6 is located on the axis 7 on which the axle sleeve 8 is located. On the axle sleeve 8, the ratchet wheel 5, the rotary lever 9, located near its end, a locking disk 10, a gear 11 and a disk cam 12.
    Ratchet 6 is equipped with an internal gear crown 13 with an odd number of teeth. The ratchet wheel b has two locks 1A, in which the compression springs 15 are mounted. The tabs 1 are located in the free space inside the ring gear 13
    ratchet 6. In addition, they have support (not shown), which are in contact with the legs 16 of the pivot arm 9.
    The clutch has a control device consisting of a pivot arm 9, a pawl 17, connected to an electromagnet 18, a torsion spring 19 acting on the pivot arm 9.
    The ratchet wheel 5 has a pitch and the thickness of the teeth and the diameter of the pitch circle, the same as the ratchet 6, on the outer surface of the tooth are located on the part of the perimeter of the ratchet wheel.
    The hrap-type freewheel works as follows.
    Coupling is caused by the inclusion of
    an electromagnet 18, as a result of which the pawl 17 releases the pivot arm 9, which is rotated under the influence of the torsion spring 19 and its legs 16 move the latches
    1 Against the force of their springs 15. Since the number of teeth is odd and the number of clamps is even, then between the teeth of the crown 13 of the ratchet 6 only one latch 1 sinks.
    The transmission of rotation is carried out by the drive 1 through the gears 2-4 to the ratchet 6 and through the included retainer 1 to the ratchet wheel 5 from which the associated parts are moved. During one revolution, the electromagnet 18 turns off and the dog 17
    occupies the initial position. After one turn, the pivot arm 9 runs onto the pawl 17 and disengages from the ratchet
    working latch 1. The ratchet 6 and ratchet wheel ij are disconnected, which is disconnected c. drive 1 and maintains its original position regardless of the further operation of drive 1, since it does not have teeth on the part of the perimeter.
    In the event of malfunctions in the machine, the coupling can be manually turned back.
