Abstract:
A modular drive system, comprising:a plurality of assemblies connectable to one another in series, wherein immediately adjoining two assemblies form, in the flow direction of the power train, a leading assembly having a case and a rotatably supported driving shaft set within the case, and a trailing assembly having a case and a driven shaft in operative communication with the driving shaft, and driven shaft being radially offset to the driving shaft; andcentering means for aligning the case of the leading assembly and the case of the trailing assembly with one another, said centering means including a centering pin received in form-fitting engagement in a single centering opening formed by complementary aligned bores provided in confronting walls of the case of the leading assembly and the case of the trailing assembly, said centering opening extending parallel to the driving shaft of the leading assembly and the driven shaft of the trailing assembly and defining a longitudinal axis which lies in a common plane with the driving shaft of the leading assembly and the driven shaft of the trailing assembly,wherein the plurality of assemblies includes a motor unit having an output pinion, a main transmission unit, and at least one subtransmission positioned between the motor unit and the main transmission unit, with the output pinion of the motor unit being of a same size as an output pinion of the at least one subtransmission.
