In the rebound mechanism, the two cams are mainly used for completing various complex motions according to working requirements, the two fan-shaped transmission wheels respectively slide at the highest points of the two cams, the circumference of the cams controls the fan-shaped transmission wheels to circulate for 120 degrees, and the fan-shaped transmission wheels drive the pointer gear to walk for 120 degrees. 13 points 0 and 12 are coincident points to be drawn in the 120-degree fan-shaped dial.
The specific working process of the double-retrograde timing clock is briefly described as follows:
1. the transmission process of the transmission mechanism during branch guide: the spring shaft 9 drives the spring gear 3, the spring gear 3 drives the transmission gear 13E, the transmission gear 13E drives the second rotating shaft 13, and the second rotating shaft 13 drives the first large guide gear 13A and the first small guide gear 13D; the first guide large gear 13A drives a second guide small gear 13C, and the second guide small gear 13C drives the first rotating shaft 11 and further drives the minute hand cam 12; the first small guide gear 13D drives the second large guide gear 13B, the second large guide gear 13B drives the shaft sleeve 1 to rotate, and the shaft sleeve 1 drives the hour hand cam 2.
2. Hour hand: the hour hand cam 2 drives an hour hand salient angle A of the hour hand fan-shaped transmission wheel 4 to slide on the excircle of the hour hand cam 2, and the hour hand fan-shaped transmission wheel 4 drives the hour hand gear 5 to rotate so as to drive the hour hand 6 to rotate. Because the arc angle of the hour hand cam 2 from the high point to the low point is 120 degrees, the hour hand sector transmission wheel 4 slides on the hour hand cam 2 to the highest point, the hour hand sector transmission wheel 120 degrees drives the hour hand gear 5 to rotate, and the hour hand gear 5 drives the hour hand 6 to rotate to 12 points (see fig. 2). Because the hour hand cam 2 rotates with the shaft sleeve 1 in a 360-degree circumference, when the hour hand 6 rotates to the tail end of the 12-point fan-shaped dial, the hour hand cam 2 continues to rotate and returns to the lowest point from the high point instantly, the hour hand lobe A of the hour hand fan-shaped transmission wheel 4 slides to the lowest point simultaneously, so that the hour hand gear 5 is driven to rotate, and the hour hand gear 5 drives the hour hand 6 to return to the zero point instantly (see fig. 3).
3. Needle separation: the minute hand cam 12 drives the minute hand convex angle B of the minute hand sector transmission wheel 14 to slide on the excircle of the minute hand cam 12, and the minute hand sector transmission wheel 14 drives the minute hand gear 15 to rotate, so as to drive the minute hand 16 to rotate. Because the arc angle of the minute hand cam 12 from the high point to the low point is 120 degrees, the minute hand sector transmission wheel 14 slides to the highest point on the minute hand cam 12 and is 120 degrees, the minute hand gear 15 is driven to rotate, and the minute hand gear 15 drives the minute hand 16 to rotate to the tail end of the sector dial (see fig. 4). Because the minute hand cam 12 rotates with the first rotating shaft 11 in a 360-degree circumference, when the minute hand 16 rotates to the end of the sector dial, the minute hand cam 12 continues to rotate and instantly returns to the lowest point from the high point, the minute hand lobe B of the minute hand sector driving wheel 14 simultaneously slides to the lowest point, thereby driving the minute hand gear 15 to rotate, and the minute hand gear 15 drives the minute hand 16 to instantly return to the zero point (see fig. 5).
