Description

Axial »sheet metal cage for cylindrical rollers

The new item is a one-piece axial sheet metal cage for cylindrical rollers with an approximately square cross-section, whose pockets holding the rollers are separated from one another by webs, which are provided with retaining edges on both sides of the roller center plane and are provided with retaining edges © sections and ₉ diagonally connecting them section © extending to the roller axis and which are connected at their two ends by ring-shaped boards that extend approximately over the entire height of the roller running surface ©

Boi a known, equipped with needle-like Wälskörpern axial cage reach the outer or inner surfaces of the parallelan web sections until close to the raceways zoom, d _o h _0, the webs extending radially as-the * board also © _s approximately over the goose © Hoh © of the roller running space ο A corresponding cage design for approximately square rollers would be difficult to manufacture without cutting. The innovation therefore provides that the webs only extend over a partial area of the running space height determined by the roller diameter and about the same size from both raceways Amount are removed «, this results in a more favorable cross-sectional shape for the manufacture of the cage with the same dimensional stability ο With a two-row roller arrangement, one stiffening of the cage gabiide can be achieved by transversely creating the two pocket-forming web rows through an annular intermediate border of single or double material cut are separated from each other _o
