Abstract
A device for stepping down and/or stepping up the speed of rotation of a motor element, such as a dental micromotor, includes two toothed pinions with common axes of rotation and which are mounted in a support piece. The support piece can turn through an angle (.alpha.) with respect to the body o the motor element about an axis (A) parallel with an axis (o) of the input pinion of the device and offset with respect to the axis (o) by a distance (OA). The axis (A) is further offset with respect to the axis (O') of rotation of the output pinion by a distance (AO') equal to the distance (OA). As a result, in a first position, the axis (O') is merged with the axis (O), and a first one of the pinions (or a crown wheel) is meshed with elements upstream of the kinematic chain. In a second position, following rotation of the support piece through a defined angle (.alpha.), the first one of the pinions is disengaged and a second one of the pinions (or a crown wheel(), is, in turn, meshed with the elements upstream of the kinematic chain.
