Problems solved by technology
like Figure 5 As shown, the common three-side turning in China is mainly driven by a single-tooth dial, that is, there is only one dial on the dial, and the inclination angle of the end face of the dial is about 45 degrees. When the dial moves the plum blossom wheel (only three In the case of plum blossom teeth), the teeth are easy to move the plum blossom wheel and slide over directly, and the phenomenon of tooth jumping occurs, so it will appear that some of the several triangular tubes are not on the same picture, resulting in picture disorder

Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0017] A three-sided double-tooth transmission mechanism, such as figure 1 As shown, it includes the active shaft 1 and the passive shaft 3. The active shaft 1 is connected with the dial wheel 2, and the passive shaft 3 is connected with the plum blossom wheel 4. The dial wheel 2 and the plum blossom wheel 4 are locked vertically to each other, as shown in FIG. figure 2 As shown, dial tooth 7 is arranged on the dial 2, and dial port 8 is provided, as image 3 As shown, the plum blossom wheel 4 is provided with a rotary tooth 5 and a plum blossom tooth 6, the dial tooth 7 corresponds to the plum blossom tooth 6, the dial mouth 8 corresponds to the rotary tooth 5, and the dial wheel 2 has two dial teeth 7, the plum blossom tooth There are six plum blossom teeth 6 on the wheel 4, and the plum blossom teeth 6 can be engaged between two shifting teeth ...

A three-facet double gear transmission mechanism which can avoid slippage phenomenon and has good transmission effect belongs to three-facet transmission devices. The transmission mechanism comprises a drive shaft and a driven shaft, the drive shaft is connected with a thumb wheel in a transmission way, and the driven shaft is connected with a wobbler wheel in a transmission way; the thumb wheel and the wobbler wheel are orthogonally locked, the thumb wheel is provided with gears and gear ports, the wobbler wheel is provided with rotating gears and wobbler gears, the gears correspond to the wobbler gears, the gear ports correspond to the rotating gears, the thumb wheel is provided with two gears, the wobbler wheel is provided with six wobbler gears, and the wobbler gears can be occluded between the two gears. In the transmission mechanism, a single-gear thumb wheel is changed into a double-gear thumb wheel (i.e. two gears), and the number of wobbler gears on the wobbler wheel is changed from three to six correspondingly; in such a way, the transmission between the thumb wheel and the wobbler wheel approximates the transmission between two bevel gears, which avoids slippage phenomenon, thus being capable of effectively ensuring frames not to be in confusion.
Description
technical field [0001] The invention relates to a three-side turning transmission device, in particular to a three-side turning double-tooth transmission mechanism. Background technique [0002] The three-sided flip is a billboard that is made up of several vertical aluminum alloy triangular tubes arranged from left to right and can automatically change pictures. It includes three sets of pictures. Three different pictures are pasted on the three sides of the triangular tube. The motor, active rotating shaft, and dial are transmitted to the plum blossom wheel, and the plum blossom wheel drives the passive rotating shaft to turn each triangular tube gradually according to different progressive times. When all the triangular tubes stop, a complete picture is formed. [0003] Although the three sides are composed of thousands of originals, there are two main originals: one is the "tracking wheel" and the other is the "plum blossom wheel". Such as Figure 5 As shown, the common...
