AI Technical Summary
The fine-tuning mechanism of existing watches has the problem of polarization adjustment requiring experienced masters, difficult to control the adjustment amplitude, and easy deformation or breaking of parts.
A balance wheel polarization and moving speed fine-adjustment mechanism is designed. The fast and slow piles with C-ring structure are stuck on the axle. The fast and slow piles are adjusted through the screw and fine-adjustment nut structure. The balance wheel polarization is adjusted by gear transmission and position adjustment of the movable outer piles, and the pendulum shaft is protected by lubrication system.
It realizes convenient adjustment of speed and slow movement and simple fine adjustment of balance wheel polarization, avoids deformation and loosening of parts, and protects the swing shaft, improving the accuracy and safety of adjustment.
