FIELD: physics.SUBSTANCE: spring motor for clocks, having a means of bringing a spring into a tension state and a spring, one end of which is attached to the means of bringing the spring into a tension state when winding, and the other end is adapted to be coupled with a means of transferring energy of rotary motion of a clock mechanism, according to the invention, has a coiled torsion spring capable of storing energy of rotary motion when the spring is wound to bring the spring into a tension state and transferring energy of rotary motion when the spring unwinds to the means of transferring energy of rotary motion to the clock mechanism. The means of bringing the spring into a tension state is in form of a shaft placed inside the spring, attached by one end to one end of the spring and the other end of which is attached to the means of transferring energy of rotary motion to the clock mechanism. A winding wheel with a dog is mounted at the end of the shaft to prevent unwinding of the spring when the shaft turns when bringing the spring into a tension state and fixing the shaft when unwinding the spring. In different versions, the clocks can be made with clock hands, tourbillon, calendar devices or with devices for indicating planetary phases, e.g. moon phases or sunrise/sunset time.EFFECT: simple design and manufacture, easy operation, reduced size of the spring motor and longer operating time of clocks.28 cl, 12 dwg |
