<p>In a planetary gear mechanism, an internal gear is mounted by means of bolts fitted with elastic washers to one end face of a bearing case which lies opposite an input shaft. The bearing case essentially surrounds an internal structure of the output-shaft side. Each elastic washer has an elastic ring and metal rings which are attached to the inner and outer circumferential surfaces of the elastic ring. Each elastic ring has openings on two sides, symmetrically in relation to its centre. The openings of each elastic ring are aligned in a circle with the input shaft as the centre. Gear spindles of the planet gears are mounted at equal spacings on the circumferential part of a disc-like planet-gear frame. Each gear spindle is supported at one end by a bearing.</p> |
