Drive train assembly for a belt drive unit of a lift system and correspondingly designed shaft and use thereof

Abstract

Even when designing drivetrains for elevator installations, an advantageous compromise between required resources and achievable technical (performance) data is desirable. Especially in the case of drivetrains with a belt drive, the shaft interacting with at least one belt at a driving zone requires structural optimization in order to be able to make use of improvement potential including with regard to further components of the drivetrain. According to the disclosure, the shaft has an absolute shaft length which is predefined by length dimensioning with reference to the width of the driving zone. In this way, a particularly advantageous compromise on the basis of length dependency and optionally in addition also of diameter dependency can be found, in particular in terms of optimization concerning both the material-machining outlay and smallest possible dimensions, wherein the respective drivetrain, on the basis thereof, can also be designed for different applications.

Dependencies are inferred from the claim text.
