Abstract
The transmission system, including a drive shaft, a driven shaft and a connecting device enabling the drive shaft to transmit mechanical torque to the driven shaft, and guide devices guiding the drive shaft in rotation about a drive axis and guiding the driven shaft in rotation about a driven axis. When the transmission system is at a standstill, the drive axis and the driven axis are misaligned, and they move closer to one another when the transmission system transmits torque from the drive shaft to the driven shaft.
Claims20
A transmission system comprising a drive shaft and a driven shaft and a connecting device mechanically connecting the drive shaft and the driven shaft, the drive shaft rotating the driven shaft by means of the connecting device, the transmission system comprising at least two first housings and at least two first guide devices guiding the drive shaft in rotation about a drive axis, each first housing accommodating one of the first guide devices, the transmission system comprising at least two second housings and at least two second guide devices guiding the driven shaft in rotation about a driven axis, each second housing accommodating one of the second guide devices,
- wherein the drive axis and the driven axis are misaligned when the transmission system is at a standstill, the drive shaft and the driven shaft and the connecting device being situated around a center line of the drive axis and the driven axis,
- the drive shaft, the driven shaft and the connecting device being situated in line with one another, the connecting device being situated between the drive shaft and the driven shaft.
A transmission system comprising a drive shaft, a driven shaft and a connecting device mechanically connecting the drive shaft and the driven shaft, the drive shaft rotatable by the driven shaft by the connecting device, the transmission system comprising at least two first housings and at least two first guide devices to be able to guide the drive shaft in rotation about a drive axis, each first housing accommodating one of the first guide devices, the transmission system comprising at least two second housings and at least two second guide devices to be able to guide the driven shaft in rotation about a driven axis, each second housing accommodating one of the second guide devices,
- wherein the drive axis and the driven axis are arranged to be misaligned when the transmission system is at a standstill, the drive shaft and the driven shaft and the connecting device being situated around a center line of the drive axis and the driven axis,
- the drive shaft, the driven shaft and the connecting device being situated in line with one another, the connecting device being situated between the drive shaft and the driven shaft.
