Abstract

The gear has a cog and an endless screw with elastically deformable elements taking up impacts and other iregular movement caused by the drive motor. Coupling elements are loacted between the post (16) and the rim (18) of the cog (14). These elements cannot rotate and have radial members (32) on the post and on brackets (28) which are in turn held at their centres to the rim and have arms engaging neighbouring radial members. At least a part of the non-rotating parts, preferably the brackets, is made of elastically deformable material. The rim has inner sectors (24) of which each is connected at its upper part of the centre of the bracket. The sectors of the rim are connected to the centre of the bracket by supports (26) that are elastically deformable.
