Abstract
The invention relates to a belt drive assembly for a drive train of a helicopter, comprising a drive shaft that can be functionally connected to a crankshaft of a drive machine of the helicopter, wherein the drive shaft is functionally connected to a belt disk via a torsional vibration damper, wherein the belt disk can rotate via a bearing mechanism on a bearing shaft connected to the drive shaft for conjoint rotation therewith, wherein the belt disk can receive a belt that is functionally connected to a rotor system of the helicopter.
Claims11
A belt drive assembly for a drive train of a helicopter, comprising:
- a drive shaft that can be functionally connected to a crankshaft of a drive machine of the helicopter, wherein the drive shaft is functionally connected to a belt disk via a torsional vibration damper, wherein the belt disk can rotate via a bearing mechanism on a bearing shaft connected to the drive shaft for conjoint rotation therewith, wherein the belt disk can receive a belt that is functionally connected to a rotor system of the helicopter, and
- further comprising an ancillary drive shaft that-is connected to the belt disk for conjoint rotation, wherein the ancillary drive shaft can be functionally connected to an ancillary unit of the helicopter.
A belt drive assembly for a drive train of a helicopter, comprising:
- a drive shaft that can be functionally connected to a crankshaft of a drive machine of the helicopter, wherein the drive shaft is functionally connected to a belt disk via a torsional vibration damper, wherein the belt disk can rotate via a bearing mechanism on a bearing shaft connected to the drive shaft for conjoint rotation therewith, wherein the belt disk can receive a belt that is functionally connected to a rotor system of the helicopter,
- wherein the torsional vibration damper comprises a spring mechanism, wherein the spring mechanism couples at least one input element to at least one output element such that vibrations are dampened, and
- wherein the at least one input element is an annular disk, and has numerous holes for axially inserting connecting means between the drive shaft and the bearing shaft.
