The transmission device 20 of the present embodiment mainly includes a structure 21, an eccentric wheel 22, a rotating shaft 23, a connecting plate 24, a through shaft pin 25, and a motor 26. Wherein the structure 21 has a lower mounting hole 211 and an upper mounting hole 212 adjacently disposed. Eccentric 22 is disposed in lower mounting hole 211. The rotation shaft 23 is inserted into the eccentric 22. The motor 26 is connected to the rotating shaft 23, and the motor 26 is configured to drive the rotating shaft 23 and the eccentric wheel 22 to rotate, so as to reciprocate the structural body 21 up and down. Specifically, the eccentric wheel 22 is configured such that the center of the shaft hole is eccentric from the axis, and mechanical vibration is generated when the eccentric wheel rotates on the rotation shaft 23. In one embodiment, the bearing B1 is disposed in the lower mounting hole 211, and the eccentric 22 is disposed in the bearing B1, so that the eccentric 22 can smoothly rotate in the lower mounting hole 211.

In one embodiment, one end of the rotating shaft 23 is sleeved with a driving wheel 231, and the motor 26 is connected with the driving wheel 231 through a driving belt 261. Therefore, the rotation power generated by the motor 26 can be transmitted to the driving wheel 231 through the driving belt 261, so as to drive the rotation shaft 23 and the eccentric wheel 22 to rotate. In an embodiment, the transmission 20 further includes a first bearing seat 27 and a second bearing seat 28, wherein opposite ends of the rotation shaft 23 are respectively disposed in the first bearing seat 27 and the second bearing seat 28. Specifically, the first bearing housing 27 includes a housing 271 and a bearing 272 provided in the housing 271, and similarly, the second bearing housing 28 includes a housing 281 and a bearing 282 provided in the housing 281.

With continued reference to fig. 3-5, the connection plate 24 is disposed above the structure 21, and the connection plate 24 is mainly capable of connecting to the housing 10. In an embodiment, the connecting plate 24 is a U-shaped plate formed by a first side plate 241, a second side plate 242 and a top plate 243, wherein the first side plate 241 is opposite to the second side plate 242, the top plate 243 is connected between the first side plate 241 and the second side plate 242, and the top plate 243 has an opening 244. Wherein the top of the structure 21 is located in the opening 244. In this embodiment, the connecting plate 24 is provided with a first distance ring A1 and a second distance ring A2 that are disposed opposite to each other, and the first distance ring A1 and the second distance ring A2 are disposed on the inner sides of the first side plate 241 and the second side plate 242, respectively, and abut against opposite sides of the structure 21 corresponding to the positions of the mounting holes 212.

Specifically, the first distance ring A1 and the second distance ring A2 sandwich the structural body 21 together, and center the structural body 21 on the connection plate 24. Therefore, the structural body 21 is centered and limited by the first distance ring A1 and the second distance ring A2, so that a larger gap between parts can be avoided, and the rhythm machine can keep regular up-and-down vibration during operation.

In one embodiment, the top plate 243 of the connecting plate 24 is connected to the housing 10, and when the structure 21 reciprocates up and down, the connecting plate 24 can swing around the axle pin 25, so as to transmit the rhythmic motion to the housing 10.

In the present embodiment, the number of bearings B2 is 2, and the bearings B2 are disposed in the upper mounting hole 212 to improve the rotation stability of the through shaft pin 25.

As can be seen from the above embodiments, the transmission device of the present utility model mainly drives the rotation shaft coupled with the eccentric wheel to reciprocate up and down through the motor so as to generate the pulsating motion, and simultaneously utilizes the design of the distance ring and the through shaft pin to install the connection plate on the structure. Therefore, the structural design not only can increase the installation and transmission stability of the integral transmission device, but also can reduce the friction between parts so as to reduce the problem of mechanical failure, thereby improving the transmission efficiency and prolonging the service life. On the other hand, the bearings arranged in the upper mounting hole and the lower mounting hole can respectively reduce the rotating friction force of the penetrating shaft pin and the rotating shaft, and improve the transmission efficiency.
