Evaluation and choice of conceptual solutions for a universal geared engine reducer

Abstract

This paper deals with the issues of evaluation and choice of conceptual solution for a universal motor gear reducer, usually carried out during its development. It is a known fact that reducers could be delivered with a motor installed or in the so-called motorless version. In case of the delivery version with the motor, they could be equipped either with special reducer electric motors or with standard (IEC) motors. In case of a reducer intended for the special motor, in motorless version it has to be equipped with IEC motor adapter, for the customer’s option to use standard motors, plus it should have a classic input shaft. In case of a reducer delivered with IEC motor, its motor might be connected indirectly, using IEC motor adaptor, or directly onto the reducer, without the use of adaptor. In both cases the reducer has to be delivered with a classic input shaft. This paper conducts the evaluation of some particular solutions by leading reducer manufacturers, with the intention to point out the most satisfactory conceptual solution.
