The principle of action tachometer hour PM-10P

The tachometer consists of counting and time mechanisms and mechanism return arrows. The counting mechanism consists of a shaft of the tachometer, and angrenage the arrows, showing the number of revolutions of the dial. Clockwork consists of site slope and regulator.
To enable the clock mechanism, you should click on "start", which through the pin sector vvodit the factory spring. Under the action of the spring pin sector is moving in the opposite direction. Together with pin moving sector and through the tribes anchor wheel transmits motion to the descending node (the escape wheel and anchor plug) and node controller (balance and hair).
The regulator controls the frequency steps of the descent, providing a constant the speed of rotation of the Cam. During operation of the nodes and the shutter controller spout ratcheting lever out of the notch on the Cam slides along the Cam profile and the releases ratchet wheel, and with it the axle, which is mounted arrow
The arrow is rotated up until the spout ratcheting lever does not sink down into the groove of the Cam and not ban ratchet wheel together with the axis. From this point on the wheel will rotate idle, as it sits freely on the shaft.
