Claims

Claim:

Fastening spring, in particular for shafts, with a disk-shaped one encompassing the shaft Flange to which the axial, with their marginal edges non-positive on the circumference of the penetrating Connect the lobes resting against the shaft and facing each other in the direction of expansion, thereby characterized in that the flange ends overlap each other in the flange plane and are bent axially with their end lugs (9, 10) and that only two tabs (5, 6) are provided, the marginal edges (7, 8) of which the shaft (12) largely include.

Fig. 2 is a plan view of the rod-like ' part of the assembled fastening tongue,

3 shows a side view of FIG. 2 with assembly pliers.

The fastening spring has one formed from a spring chair or some other resilient material Disc on, through a slot in opposite, relatively resilient arcuate Arms 1 and 2 is divided. Each arm 1, 2

ίο has a flat outer part 3 or 4 and one arched inner part 5 and 6, the inner edge 7 and 8 of which is arcuate. so that the opposite Edges 7, 8 form an opening, the j diameter of which is somewhat smaller than the diameter of a j wave-like part 12 is to which the fastening spring is to be attached.

The free ends of the arms 1, 2 overlap and are bent upwards to be integral with to form them trained noses 9, 10, the

Facing each other and at right angles to each other the adjacent surfaces of the arms 1, 2 extend. The fastening spring is arranged on a shaft 12, to fix a wheel 13 on this under axially directed pressure, the edges 7 and 8

»5 step into firm frictional engagement with shaft 12.

If the fastening spring is to be removed from the shaft 12, a pair of pliers 14 is used, in order to grasp the opposing lugs 9, 10 and to press them against one another. As a result of the Order of the noses 9, 10, the arms are bent outwards by this pressing against each other, so that the frictional engagement with the shaft 12 is removed and the mounting spring conveniently removed can be.
