<p>A gear mechanism, incorporating a driving input shaft (11), an output shaft (12) arranged coaxially thereto, a first gear rim (21) arranged in a bearing housing (15) and being coaxial relative to said shafts, a second gear rim (22) provided on the output shaft (12) and a ring (18) having double gear rings (19,20) and being excentrically supported on the input shaft (11), one of which gear rings (19) is partially in gear engagement with the gear rim (21) facing inwards and the other gear ring (20) of which is partially in gear engagement with the gear rim (22) facing outwards. The purpose is to provide a gear mechanism having a big gear ratio in a compact design and at a low price. This has been obtained in that the ring (18) is constituted by the outer race ring of a rolling bearing (17), the inner race ring of which is excentrically arranged upon the input shaft (11).</p> |
