In planetary gears for example the sun wheel may adjust itself freely within certain limits with respect to the planet wheels so that it seeks such a place for itself in which the load is divided evenly among the planet wheels. However a result of this arrangement is the tendency of the gearing to vibrate especially when the load on the gearing is small. The invention presents a planetary gear construction in which the shaft (7; 12) leading to the gearing or both the shafts leading to and away from (20; 21) the gearing are fastened to the gearing's frame (17) with bearings with the aid of an elastic part (10; 15; 22, 23). The said elastic part is a circular rubber bushing or such that is placed in connection with that bearing (19; 14; 24, 25) that is closest to the planetary gear and which represses the said tendency to vibrate but which at the same time allows the centralizing of the sun wheel or such. The invention can be applied to both planetary gears that are equipped with a ring wheel (3; 18) or to so-called incomplete planetary gears that do not have a ring wheel. |
