ABSTRACT:
The sun and planet gear transmission mechanism comprises a power input shaft and at least two successive gear steps including a first gear step and a second gear step disposed within a gear casing. Each gear step includes a sun gear and at least one planet gear. The sun gear of the first gear step is connected to the power input shaft. The power input shaft is axially displaceable so that the sun gear may be disengaged with the appertaining planet gear in the first gear step. Coupling means located at an adjacent gear step is effective to engage the sun gear of the first gear step when said sun gear is disengaged from said planet gear in the first gear step.
