LOCK OF BALANCE SPIRAL Russian patent published in 2015 - IPC G04B18/00 

FIELD: machine building.

SUBSTANCE: lock of balance spiral is suggested. It is made with possibility of installation in the balance spring assembly to adjust the clock spiral, having the possibility of rotation relatively axle (D) parallel to the rotation axle of the balance spiral or coinciding with this axle. At that the balance spiral lock contains two projecting pins and support devices. The two projecting pins are located in parallel to each other along one direction (D1) at definite distance from each other, are made with possibility of the radial runout limitation of the installed between them balance spiral, and are polished to minimise friction between them and the balance spiral. The support devices of the balance spring assembly are made with possibility of location of the said direction (D1) of the projecting pins during the lock installation on the balance spring assembly in parallel with the axle of rotation of the balance spring assembly. There is an inspection hole located in parallel with the direction (D1) of the projecting pins and ensuring the operator with possibility of the direct or using the optical device monitoring of the projecting pins and spiral area between them being at distance and/or touching one and/or another said pins. Besides the balance spring assembly is suggested to balance the clock spiral. It is made with possibility of rotation relatively to the axle (D) parallel to the axle of rotation of the balance spiral or coincided with this axle, and containing lock of the balance spiral described above. Wherein the spiral lock is inserted in the balance spring assembly such that the direction (D1) is parallel to the axle (D). Besides the regulating assembly of the clock mechanism is suggested. It contains at least one balance spiral having possibility of rotation around the axle and supported by the lock of the balance spiral described above. The direction (D1) is parallel to the axle of rotation of the balance spiral. Besides the regulating assembly of the clock mechanism is suggested. It contains at least one balance spiral having possibility of rotation around the axle and supported by the balance spring assembly described above. The direction (D1) is parallel to the axle of rotation of the balance spiral. Besides the clock mechanism (version 1) is suggested. It contains at least one regulating assembly containing at least one balance spiral having possibility of rotation around the axle and supported by the lock of the balance spiral described above. The direction (D1) is parallel to the axle of rotation of the balance spiral. Besides the clock mechanism (version 2) is suggested. It contains at least one regulating assembly containing at least one balance spiral having possibility of rotation around the axle and supported by the balance spring assembly described above. The direction (D1) is parallel to the axle of rotation of the balance spiral. Also clock is suggested. It contains at least one clock mechanism (version 1). Also clock is suggested. It contains at least one clock mechanism (version 2).

EFFECT: improved design.
