The tower clock is a mechanical and electrical product, that is, there are two kinds of mechanical and electromechanical, with travel time, time, lighting and other functions. Many people do not know how the tower clock works, how its upper bar and the dial needle are, let's take a look at it below.
The stitching and pulling are achieved through the handle head piece. When the vertical wheel and the clutch wheel are engaged, when the handle head is turned, the clutch wheel drives the vertical wheel, and the vertical wheel passes through the small steel wheel and the large steel wheel to make the shaft wind up. The pawl prevents the big steel wheel from reversing.
The top bar and the dial of the tower clock
Seat clocks and wall clocks, including large tower clocks, dial the needle all use the finger to directly dial the needle, this adjustment will often be carried out, because the vast majority of such clocks are all mechanical, usually the travel time accuracy is not very high. Old fashioned clock and wall clock. At that time, the minute hand are steel, relatively thick, but also strong, there is generally no problem when the needle, and some of the watch hands produced now are relatively weak, so that the minute hand will be broken when the needle is turned.
When pulling the needle, pull out the handle head, the pull gear rotates on the pull shaft and pushes the clutch rod, so that the clutch wheel and the vertical wheel are detached and engaged with the needle wheel. At this time, by turning the handle head, the needle wheel drives the time wheel and the split wheel through the cross-wheel to achieve the purpose of correcting the hour and minute hands.
The stability of the clockwork torque, the smoothness of the drive train and the accuracy of the escapement governor can all affect the travel time accuracy of the tower clock. The upper bar and the dial needle of the tower clock are realized by the head of the handle.
The tower clock needs to be accurate, stable and reliable. However, some internal factors and external environmental conditions will affect the travel accuracy of the tower clock. Internal factors include the structural design of each component system, working performance, selection of materials, processing technology and assembly quality
