Abstract
In many precision engineering applications, silent running of gear mechanisms is striven for. Difficulties are encountered in particular in stepwise driving due to the play which is required when the gearwheels are engaged in one another. The invention provides a gearwheel which is suitable for transmitting small torques and makes the production of a silent gear mechanism possible. This plastic gearwheel is composed of an inner pinion (10) and an outer gear rim (12) connected thereto by spiralling arms (16). By this means, a very soft spring action of the outer gear rim (12) is achieved, this permitting play-free and hence silent engagement in the said gear rim. Despite the long, thin arms, production of this gearwheel in one piece by injection moulding is possible in that in the centre of the said arms a thickened portion (24) is provided, in the region of which the injection mould is vented. <IMAGE>
