Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 5, the large-plate double-speed change mechanism of the mahjong machine comprises a large-plate motor 1 and a large-plate motor gear 2, and further comprises a driving gear 111, a first transmission gear 112, a second transmission gear 113, an intermediate gear 114 and an output gear 115, wherein the driving gear 111 is mounted on an output shaft of the large-plate motor 1, the driving gear 111 is respectively meshed with the first transmission gear 112 and the second transmission gear 113, the first transmission gear 112 is mounted on the intermediate shaft through a first one-way bearing, the intermediate gear 114 is mounted on the intermediate shaft, and the first transmission gear 112 and the intermediate gear 114 are coaxially linked; the second transmission gear 113 is mounted on an output shaft through a second one-way bearing, the output shaft is provided with an output gear 115, the second transmission gear 113 and the output gear 115 are coaxially linked, and the intermediate gear 114 is meshed with the output gear 115; the set rotating directions of the first one-way bearing and the second one-way bearing are opposite; and a large-disk motor gear 2 is mounted on the output shaft.
Further, the number of teeth of the first transmission gear 112 and the second transmission gear 113 is a, the number of teeth of the intermediate gear 114 is b, the number of teeth of the driving gear 111 is c, the number of teeth of the output gear 115 is d, wherein a, b, c and d are positive integers, and a < b < c < d.
The large-disk motor 1 is arranged on a large-disk motor support 3, the large-disk motor support 3 is fixed on a large bottom plate 4, the large-disk motor gear 2 is meshed with an inner gear ring of a large disk, and the large disk 5 is rotatably arranged on a central shaft seat 6.
In this embodiment, in the double-speed change gear mechanism 7, the driving gear is driven by the driving motor, the driving motor is a motor capable of rotating in forward and reverse directions, the output speed of the driving motor is constant, and simultaneously drives the first transmission gear or the second transmission gear, because a coaxial but reverse one-way bearing is respectively fixed inside the first transmission gear or the second transmission gear, the driving gear can only drive one of the transmission gears, that is, only one transmission gear generates torque at each steering direction no matter in forward rotation or reverse rotation, and the transmission gear generating the torque drives the next-stage gear to rotate, thereby achieving the effect of outputting the torque. Because the first transmission gear drives the output gear through the intermediate gear and the second transmission gear directly drives the output gear, the positive and negative rotation functions of the driving motor can respectively generate two homodromous rotating speeds.
Example (c): the number of teeth of the driving gear is 19 teeth, the number of teeth of the first transmission gear is 16 teeth, the number of teeth of the second transmission gear is 16 teeth, the number of teeth of the middle gear is 15 teeth, and the number of teeth of the output gear is 23 teeth.
From the overlooking perspective, if the driving gear rotates clockwise 100 revolutions per minute, the first one-way bearing generates torque to drive the first transmission gear, the second one-way bearing generates no torque, the rotating speed of the intermediate gear is 100 x (19/16) revolutions per minute, and the rotating speed of the output gear is 100 x (19/16) x (15/23) revolutions per minute; if the driving gear rotates 100 revolutions per minute anticlockwise, the second one-way bearing generates torque to drive the second transmission gear, no torque is generated by the first one-way bearing, the rotating speed of the second transmission gear is 100 x (19/16) revolutions per minute, then the rotating speed of the output gear is 100 x (19/16) revolutions per minute, and output of two different speeds is achieved.
In this embodiment, the first transmission gear 112 and the second transmission gear 113 are internally provided with one-way bearings.
When the driving gear 111 rotates counterclockwise, the first one-way bearing generates torque to drive the first transmission gear 112, and the output gear 115 is driven by the intermediate gear 114 to rotate counterclockwise, so as to drive the big disc motor gear to rotate counterclockwise at a slow speed;
when the driving gear 111 rotates clockwise, the second one-way bearing generates torque to directly drive the second transmission gear 113 and the output gear 115 to rotate counterclockwise, and the gear of the large-disk motor is driven to rotate counterclockwise rapidly from the surface.
The mahjong machine large plate is controlled in a one-way high and low speed mode through the rotation modes of the two large plate motors.
