SU723491A1 - Device for automatic electric winding-up of time-piece spring - Google Patents

Description

3 -72

The flap on the winding shaft 13 is associated with a spring-loaded motor 1. On the axis 15 of the winding reducer, a cam 4 is rigidly fixed with a lock 5, connected via the start lever 6 and the cam 8 with the axis 14 of the gear reducer. Lever arm

start 6 also serves to control the first contact group 10 including the electric motor. On the axis 14 of the stroke reducer, a pair of cams 12 are rigidly fixed, controlling the second contact fuppa 1

motor 19 and cam 9. The contact groups 10 and I are electrically connected to each other in series.

Before launching contact groups 10 and 11 are closed. When the power is supplied, the electric motor 19 rotates the gear train 2 and the winding wheel 3 through the gear of the winding 16 and the cam motor 4, which is fixed on the axis 15 of the winding gearbox, also rotates. When the axis 15 makes a full turn, the start lever 6 will retract the gate valve 5, sink into the groove of cam 4 and open the contact group 10, turning off the power of the electric motor. When the device is working, the axis 14 rotates and the contact group 11 opens first, and after a while the cam 8 pulls the start lever 6 out of the groove of the cam 4 to the surface of the valve 5 and the contact group closes 10. At the end of the cycle, the cams 12 close the contact group

winding 11. A new winding cycle begins.

When the winding is connected with the start, the start lever 6 when dropping into the groove of the cam 4, removes the balance start lever 7 from the groove of the additional cam 9 and starts the balance of the trigger 18.

Claims (2)

1. Device for automatic electro-winding of spring motors of time devices, comprising an electric motor, a winding reducer connected via a winding wheel with a spring motor, cams, a contact group, a gear reducer, a balance start lever, distinguished by the fact that in order to increase the accuracy of the stroke reducing the difference in torque on the anchor wheel and reducing the size; a cam with a flap is installed on it, mounted on the axle of the winding reducer, a start lever associated with the cam, a balance start lever and one contact a motor switching group, and a pair of cams associated with the motor start contact group and a cam associated with the start lever are located on the stroke reduction axis. 2. The device according to claim 1, so that, in order to ensure the launch at the end of the winding, an additional cam is mounted on the axis of the gear reducer connected through the balance start lever with the trigger regulator and lever start.
