DEVICE FOR MAINTAINING THE STEADY ROTATION FREQUENCY OF A MECHANICAL SYSTEM OUTPUT AT A VARIABLE INPUT LOAD AND METHOD FOR OPERATING SAID DEVICE

摘要

The invention relates to clockwork drives and oscillating systems and can be used in the watch and instrument-making industry for equalising a speed of rotation with respect to an external load. Oscillating systems and clockwork drives based on energy pulse transmission to a balance-spring system with the aid of anchor escapements and mobile elements have certain defects related to a system balancing problem, the reliability, energy consumption etc. For this purpose, the inventive oscillating system is embodied in the form of connected resonators having a non-linear transfer function the mass of which is exposed to a load action (torque M). In terms of kinetics, said system can be absolutely symmetric apart from a balance spring whose influence is reducible by rotation of a balance-spring system at a frequency which is greater than a tourbillon system frequency. The inventive system exhibits a high smoothness of movement, thereby reducing the wear thereof and increasing the reliability.
