Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of mechanical timer of present embodiment, as shown in Figure 1, comprise train wheel bridge 1, lower plate 2 and be installed in train wheel bridge 1 and lower plate 2 between clockwork spring 3, gear train and escapement, gear train comprises that the great wheel 4, two that is meshed successively takes turns 5 and three-wheel 6, and great wheel 4 and clockwork spring 3 are coaxially installed on the Control Shaft 13 that passes train wheel bridge and lower plate.Escapement comprises escape wheel 7, hairspring 8, escapement 9 and pendulum nail 10, as Fig. 3, Fig. 4, shown in Figure 5, hairspring 8 and escapement 9 are coaxially installed on the balancing arbor 11, and hairspring 8 is positioned at the top of escapement 9, pendulum nail 10 is installed on the last plane of escapement 9, and pendulum nail 10 is parallel with balancing arbor 11, and escape wheel 7 not only meshes with three-wheel 6 but also follows closely 10 engagements with pendulum.A groove 12 is arranged on the balancing arbor 11, and groove 12 is between hairspring 8 and escapement 9, and the height of the position of groove 12 and escape wheel 7 is complementary, and groove 12 is towards escape wheel 7.In the present embodiment, the length L of groove 12 is 2.6mm, and the diameter of the great circle of hairspring 8 is 11.81mm, the height H of hairspring is 0.4mm, the thickness of escapement 9 is 3.25mm, and pendulum nail 10 height that are exposed to escapement 9 are 3.7mm, and the distance D between the axis of pendulum nail 10 and the axis of escapement 9 is 3.9mm.As shown in Figure 2, escape wheel 7 is spiral gears, and helical gear tooth paddy is 5.64mm to the distance R 1 in the spiral gear center of circle, and helical gear tooth peak is 7.09mm to the distance R 2 in the spiral gear center of circle.
