Description
Technical field
The utility model relates to automatic mahjong-playing machine and inhales board apparatus average rate intermittent transmission device.
Background technique
Automatic mahjong-playing machine is a kind of recreation entertainment equipment that people commonly use, being divided into has magnetic mahjong machine and without magnetic mahjong machine, for there being magnetic mahjong machine, when mah-jong pieces turn over as after facing up on shuffle disk, the suction board be arranged on four positions wheel is picked up, mah-jong pieces after picking up will be followed to inhale after board wheel rotates about 180 degree and be pushed in folded board groove by mah-jong pushing device, because mah-jong pushing device pushes mah-jong pieces need the time, this just makes to inhale board wheel and is in evenly spaced intermittent movement state.And existing indexing mechanism mainly contains following several:
Ratchet mechanism: have noise, impact, the gear teeth are easy to wear, has larger impact and noise during work;
Geneva mechanism: at rotation beginning, end, accelerate to change greatly, have impact;
Intermittent gearing mechanism: simple, the easy manufacture of structure, follower run duration and the ratio of quiescent time can change in a big way,
Cam intermittent mechanism: the characteristics of motion of driven disc depends on cam profile, cam cutting is more complicated, mounting and adjusting requires strict.
What can use in mahjong machine only has intermittent gearing mechanism, but by spacial influence in mahjong machine, inhaling board wheel can not be direct and driven intermittent wheel coaxial, and in automatic mahjong-playing machine, be therefore badly in need of a set of structure simply can the mechanism of even intermittently-driving.
Model utility content
The purpose of this utility model is to provide automatic mahjong-playing machine to inhale board apparatus average rate intermittent transmission device average rate intermittent transmission device, can effectively solve in existing automatic mahjong-playing machine to lack structure and simply to take up room the problem of average rate interval of little stable performance.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: automatic mahjong-playing machine inhales board apparatus average rate intermittent transmission device, comprise driving wheel and driven intermittent wheel, driving wheel is connected with the output shaft of driver, driven intermittent wheel is taken turns with suction board and is connected, driving wheel comprises incomplete cylindrical gears and the active limit cam of coaxial also synchronous axial system, driven intermittent wheel comprises the cylindrical gears of coaxial synchronous rotation and driven limit cam, initiatively limit cam is provided with at least one section of convex arc surface, driven limit cam is provided with at least one section of concaved circular cambered surface, cylindrical gears engages with incomplete cylindrical gears interval, cylindrical gears and incomplete cylindrical gears depart from when engaging, convex arc surface and concaved circular cambered surface start to coordinate and are slided by the relative concaved circular cambered surface of convex arc surface.
Preferably, the gear teeth subsection setup of described incomplete cylindrical gears and circumference is provided with at least one section of gear teeth section, the number of teeth of all gear teeth sections is equal, and the length of all convex arc surface is equal, and convex arc surface and gear teeth section interval in the circumference of driving wheel is arranged; Ensure that the spacing of inhaling the upper each mah-jong pieces of board wheel is equal, inhaling board, to take turns the angle at every turn turned over also identical.
Preferably, described gear teeth section has two sections, and described convex arc surface also has two sections, and the concaved circular cambered surface of described driven limit cam has four sections; Driving wheel rotates a circle, and driven intermittent wheel will rotate half-turn, underspeed and be convenient to reserve the enough showdown time to piece-pushing mechanism.
Compared with prior art, the utility model has the advantages that: driving wheel is connected with driver output shaft, the cylindrical gears of driven intermittent wheel is taken turns with suction board and is connected, inhale board to take turns remain static when the convex arc surface of driving wheel coordinates with the concaved circular cambered surface of driven intermittent wheel, being convenient to mah-jong pushing device pushes in folded board groove by mah-jong pieces, and when the incomplete cylindrical gears of driving wheel engages with the cylindrical gears of follower, rotatory force is passed to suction board wheel as intermediate transfer wheel by the cylindrical gears of follower, thus make suction board take turns the certain angle of rotation, next mah-jong pieces is in be about to be pushed into the position of folded board groove, this apparatus structure is simple, the thickness taken is little, be convenient to mahjong machine internal placement, the intermittent rotary inhaling board wheel can be realized preferably.
Accompanying drawing explanation
Fig. 1 is structural representation when not exclusively cylindrical gears engages with cylindrical gears in the utility model automatic mahjong-playing machine suction board apparatus average rate intermittent transmission device;
Structural representation when Fig. 2 is convex arc surface and concaved circular cambered surface relative sliding in the utility model automatic mahjong-playing machine suction board apparatus average rate intermittent transmission device.
Embodiment
Consult Fig. 1, Fig. 2 is the embodiment that the utility model automatic mahjong-playing machine inhales board apparatus average rate intermittent transmission device, automatic mahjong-playing machine inhales board apparatus average rate intermittent transmission device, comprise driving wheel 1 and driven intermittent wheel 2, driving wheel 1 is connected with the output shaft of driver, driven intermittent wheel 2 is taken turns with suction board and is connected, driving wheel 1 comprises incomplete cylindrical gears 11 and the active limit cam 12 of coaxial also synchronous axial system, driven intermittent wheel 2 comprises cylindrical gears 21 and the driven limit cam 22 of coaxial synchronous rotation, initiatively limit cam 12 is provided with two sections of convex arc surface 13, driven limit cam 22 is provided with four sections of concaved circular cambered surfaces 23, cylindrical gears 21 engages with incomplete cylindrical gears 11 interval, cylindrical gears 21 and incomplete cylindrical gears 11 depart from when engaging, convex arc surface 13 and concaved circular cambered surface 23 start to coordinate and are slided by the relative concaved circular cambered surface 23 of convex arc surface 13.The gear teeth subsection setup of described incomplete cylindrical gears 11 and circumference is provided with two sections of gear teeth sections 14, the number of teeth of all gear teeth sections is equal, and the length of all convex arc surface 13 is equal, and convex arc surface 13 and gear teeth section interval in the circumference of driving wheel 1 is arranged.
