ABSTRACT:
An adjusting device with an overload slip system and a slip-independent position indicator includes a driving system and an adjusting member movable by the driving system between two end stops. The driving system includes an electric motor housed in a housing and a planetary transmission connected to the motor shaft, the power output shaft of the transmission being in engagement with the adjusting member. A stationary, internally toothed ring of the planetary transmission is confined between facing peripheral edges of the divided housing and is capable of slipping relatively to the edges of the housing under overload conditions. A support plate with a circular electrical resistor is fixedly connected to the housing on the side of the power output shaft. A runner contact connected to the power output shaft is movable over the resistor. The support plate with the electrical resistor and runner contact form a position indicator operating as a potentiometer, which continues to indicate the exact position of the adjusting member when slip occurs.
