The present disclosure provides for a drivetrain arrangement for a drive unit of an elevator system. The drive unit includes at least one belt drive, with a shaft mounted in a housing in a fixed bearing and in a movable bearing. The fixed bearing can be/become secured in an axially fixed manner on the shaft without a bearing cover in several circumferential positions in each case via at least one disc interacting with the housing. A reservoir is configured between the bearings and a brake unit to receive bearing grease. An inner diameter of the fixed bearing is smaller than or greater than an inner diameter of the movable bearing such that in the axial assembly direction, the bearing with the larger inner diameter can be brought over the shaft portion intended for the bearing with the smaller inner diameter. This simplifies the assembly and implementation of the drive.
A drivetrain arrangement for a drive unit/belt drive unit of an elevator system, comprising:
