Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.
Example 1
As shown in fig. 1, the variable speed driving mechanism for a mahjong machine of the embodiment includes a circumferential driver 1 and a rotational speed output member 2, and a slow driving path and a fast driving path are formed between the circumferential driver 1 and the rotational speed output member 2, so that the rotational speed output member 2 can output two speeds of rotational speed, and when the output end of the rotational speed output member 2 is connected with a driven member, different rotational speeds can be given to the driven member.
In the embodiment, a motor 11 is adopted as the circumferential driver 1, and the rotating speed output part 2 is rotatably arranged on an output shaft 11a of the motor 11 through a first one-way bearing 3; as shown in fig. 2, a speed increasing transmission unit 4 is further provided between the output shaft 11a and the rotational speed output member 2 at the end of the rotational speed output member 2 facing the motor 11, the speed increasing transmission unit 4 is also in one-way transmission with the output shaft 11a, and the transmission direction of the speed increasing transmission unit 4 is opposite to the transmission direction of the rotational speed output member 2 with reference to the output shaft 11 a.
As shown in fig. 3, as can be seen in conjunction with fig. 2, the speed increasing transmission unit 4 of the present embodiment includes a drive gear 41, the drive gear 41 is rotatably mounted on the output shaft 11a through a second one-way bearing 42, and the transmission direction of the second one-way bearing 42 is opposite to the transmission direction of the first one-way bearing 3; the rotational speed output member 2 has a ring gear 44 disposed concentrically with the drive gear 41, and the ring gear 44 is in meshing transmission with the drive gear 41 via a speed increasing gear 43.
Since the transmission direction of the second one-way bearing 42 is opposite to the transmission direction of the first one-way bearing 3, when the output shaft 11a rotates in the forward direction, the rotation speed output member 2 can rotate in the forward direction and at a slow speed, but the drive gear 41 does not rotate; when the output shaft 11a rotates reversely, the output shaft 11a cannot directly drive the rotation speed output member 2 to rotate, but can drive the driving gear 41 to rotate reversely, the speed increasing gear 43 transmits power to the inner gear ring 44, and the rotation speed output member 2 rotates forward and rapidly along with the power.
In the present embodiment, the forward rotation and the reverse rotation are relative, and there is no absolute forward and reverse.
In the present embodiment, the radius of the speed increasing gear 43 is smaller than the radius of the drive gear 41, and therefore the speed increasing transmission unit 4 can impart a larger rotation speed to the rotation speed output member 2. The arrangement mode can design the rotating speed output part 2 with smaller volume, and has relatively lower requirement on the output torque of the motor 11, thereby saving the cost.
As shown in fig. 4, as seen in conjunction with fig. 2, the speed-increasing gear 43 has a gear shaft 45, and one end of the gear shaft 45 remote from the speed-increasing gear 43 has a connecting portion 45 a; the outer diameter of the connecting part 45a is smaller than that of the gear shaft 45, so that an annular limiting convex brim 45b can be formed between the connecting part 45a and the gear shaft 45; the housing 11b of the motor 11, specifically the motor cover 11ba, is provided with a through hole 11bb adapted to the connecting portion 45a, and after the connecting portion 45a passes through the through hole 11bb, the position-limiting ledge 45b abuts against the motor cover 11ba to form a position limitation for the gear shaft 45.
The number of the speed-increasing gears 43 can be set by oneself as required, and one or two or more than two can be set; when two or more speed-increasing gears 43 are provided, all the speed-increasing gears 43 may be arranged in a planetary manner on the outer periphery of the drive gear 41. Accordingly, a corresponding number of through holes 11bb are also required in the motor 11 cover to support the corresponding gear shafts 45.
In this embodiment, the speed-increasing gear 43 and the gear shaft 45 may be integrally formed or circumferentially fixed, and at this time, the gear shaft 45 is rotatably connected to the housing 11 b; the speed-increasing gear 43 and the gear shaft 45 can also be connected in a circumferential rotating manner, and at this time, the gear shaft 45 and the machine shell 11b can be fixedly arranged in the circumferential direction or connected in the circumferential rotating manner; so long as it is ensured that at least one position between the speed-increasing gear 43 and the gear shaft 45, and between the gear shaft 45 and the housing 11b is circumferentially rotationally connected.
In the axial direction, the gear shaft 45 and the housing 11b may be axially fixed, or may be detachably sleeved, and obviously, the detachable connection of the gear shaft 45 and the housing 11b is more favorable for maintenance or replacement of parts, but the structure is relatively more stable when the gear shaft is axially fixed and connected.
In the speed change driving mechanism of the embodiment, only one rotation speed output member 2 is arranged, and the driven member is driven by only one rotation speed output member 2, so that the transmission mode between the rotation speed output member 2 and the driven member can be set more variously. For example, the output end of the rotating speed output part 2 can be directly fixedly arranged or detachably fixedly connected with the driven part, and the transmission mode is more suitable for the condition that the driven part is a mahjong tile sucking wheel;
for another example, the output end of the rotating speed output member 2 can be in meshing transmission with the driven member through a gear pair, as shown in fig. 1, and at this time, the rotating speed transmission member is fixedly or detachably provided with an output gear 21; the transmission mode can be applied to most cases that the driven piece is a shuffling large plate, a shuffling seat or a card sucking wheel and the like.
For another example, the output end of the rotating speed output member 2 can be driven by an annular transmission member, the annular transmission member can be a transmission belt, and at this time, a roller is correspondingly fixedly or detachably mounted on the rotating speed output member 2; the annular transmission belt can also be a transmission chain, and a chain wheel is correspondingly fixedly or detachably arranged on the rotating speed output part 2; the transmission mode is more suitable for the condition that the driven piece is a card sucking wheel.
The working principle of the variable-speed driving mechanism for the mahjong machine is as follows:
when the motor 11 is started, the output shaft 11a rotates forwards firstly, and drives the rotating speed output part 2 to rotate forwards and slowly through the first one-way bearing 3, and at the moment, the rotating speed output part 2 gives a slower rotating speed to a corresponding driven part through a corresponding transmission mode; in this process, the second one-way bearing 42 and the drive gear 41 do not rotate;
in any state, the output shaft 11a rotates reversely, at this time, the first one-way bearing 3 does not rotate, but the second one-way bearing 42 and the driving gear 41 rotate reversely, the speed increasing gear 43 rotates forward, under the meshing transmission of the speed increasing gear 43 and the inner gear ring 44, the rotating speed output member 2 also rotates forward and fast along with the speed increasing gear 43, and at this time, the rotating speed output member 2 gives a faster rotating speed to the corresponding driven member through the corresponding transmission mode.
