Subject: column wheel mech. Пожалуйста, помогите перевести.Выражение встречается в следующем контексте: This complication is completed with a column wheel chronograph with direct coupling on the tourbillon, whose operation, controlled by a single pusher, can be seen through the dial. Заранее спасибо |
 the caliber 410 uses an absolutely classic column wheel design for chronograph functions. Illustrated left are (1) the column wheel itself; (2) the ratchet wheel that rotates the column wheel; and (3) the click operated by the case pushers that rotates the ratchet wheel (and thus column wheel). Because the Zenith column wheel switching design is so typical of traditional Swiss chronographs, it provides a useful lesson in column wheel design. An enlarged illustration of the column wheel is shown below.
In addition to the column wheel itself (1), all the chronograph switch levers are illustrated. Spring (3) detents the column wheel to discreet positions as it is rotated by the pusher click (2). Lever 4 switches the chronograph intermediate wheel, powering the chronograph center wheel off the fourth wheel (illustrated below). Lever 5 switches the minute accumulator wheel in and out of contact with the chronograph center wheel and provides reset-to-zero. Lever 6 switches the brake lever. In each position of the column wheel, the beak of each lever either lies on top of a column (as with the intermediate wheel lever, 4) or between columns (as with the accumulator lever, 5). It is thus that starting, stopping, braking, and reset-to-zero functions are accomplished and perfectly coordinated. |

Column wheel (In French: roue à colonnes) The wheel which coordinates the start, stop and return to zero functions of the chronograph hand. In a standard quality chronograph, the column wheel is replaced by a system of cames. http://www.hautehorlogerie.org/en/encyclopaedia/glossary/column-wheel.html |
