Estimating the term…
The invention relates to a belt pulley for the output shaft of a gear being driven by an electric motor, with a support for a drive belt at the outer periphery and a receptacle for an axle in the centre, where the receptacle for the axle involves a first region, the profile of which is in such a way noncircular, that between an axle being insertable therein and the belt pulley no slip is possible, and wherein the receptacle for the axle involves a second region including at least one recess apt to allow an elastic part of the axle to snap in a form-fit way when inserted into the belt pulley through the first region. The invention further relates to a gear, to an electric motor, and to an output shaft.
A belt pulley for the output shaft of a gear being driven by an electric motor, with a support for a drive belt at the outer periphery and a receptacle for an axle in the centre, wherein the receptacle for the axle involves a first region, the profile of which is in such a way noncircular, that between an axle being insertable therein and the belt pulley no slip is possible, wherein the receptacle for the axle involves a second region including at least one recess apt to allow an elastic part of the axle to snap in into a form-fit way when inserted into the belt pulley through the first region, and that the recess in the second region is a circular groove open to the exterior.
An output shaft for a gear, with an area apt to receive a belt pulley, in which the area apt to receive a belt pulley involves a first region on the side towards the gear, the profile of which is in such a way noncircular, in which between the shaft and a belt pulley to be applied there no slip is possible, and in which the area apt to receive the belt pulley involves a second region on the side turned away from the gear involves at least one elastic part apt to snap in into a recess of the belt pulley in a form-fit way, that is made in one piece together with an axle and a worm wheel with helical gearing forming the last gear wheel of the gear.
