Transmission device

Abstract

A transmission device is suitable for installation between a drive shaft and a driven shaft, wherein the drive shaft and the driven shaft extend in the same direction. The transmission device includes a first connecting member, a second connecting member, and a plurality of swing arm units. The first connecting member is disposed on the drive shaft. The second connecting member is disposed on the driven shaft. The swing arm units are disposed at equal angular intervals between the first connecting member and the second connecting member. Each swing arm unit includes a first swing arm extending radially outward from the first connecting member, a second swing arm extending radially outward from the second connecting member, and a crossover member disposed between the first swing arm and the second swing arm. Through the structural design of the swing arm units, stability during kinetic energy transmission can be improved by preventing wobbling during operation.

Claims

1. A transmission device suitable for installation between a drive shaft and a driven shaft, the drive shaft and the driven shaft extending in the same direction, the transmission device comprising: a first connecting member for being disposed on the drive shaft; a second connecting member for being disposed on the driven shaft; and a plurality of rotating arm units disposed at equal angular intervals between the first connecting member and the second connecting member, each rotating arm unit comprising a first rotating arm extending radially outward from the first connecting member, a second rotating arm extending radially outward from the second connecting member, and a crossover member disposed between the first rotating arm and the second rotating arm.

2. The transmission device as claimed in claim 1, wherein, The bridging member of each of the swing arm units extends along the extension direction of the drive shaft.

3. The transmission device as claimed in claim 1, wherein, Each of the first rotating arms has an opposite first inner end and a first outer end, each of the first inner end being connected to the first connector, and each of the second rotating arms has an opposite second inner end and a second outer end, each of the second inner end being connected to the second connector.

4. The transmission device as claimed in claim 3, wherein, The two opposite ends of each jumper are disposed between the corresponding first outer end and the corresponding second outer end.

5. The transmission device as claimed in claim 4, wherein, Each of the jumpers has a fixed end and a mounting end, the fixed end of each jumper being fixedly connected to one of the corresponding first outer end or the corresponding second outer end, and the mounting end of each jumper being detachably connected to the other of the corresponding first outer end or the corresponding second outer end.

6. The transmission device as claimed in claim 5, wherein, Each of the swing arm units also includes a buffer disposed at the mounting end of the corresponding jumper, the mounting end being connected to the corresponding first outer end or the corresponding second outer end through the buffer.

7. The transmission device as claimed in claim 1, wherein, The first connector is disc-shaped and centrally connected to the drive shaft.

8. The transmission device as claimed in claim 7, wherein, The second connector is disc-shaped and centrally connected to the driven shaft.

9. The transmission device as claimed in claim 8, wherein, The radius of the second connector is larger than the radius of the first connector.
