LAGERELEMENT FUER EIN GELENK IN TRIPOD-BAUART UND VERFAHREN ZU SEINER HERSTELLUNG

摘要

The object of this invention is to improve the performance of the tulip members in the regions of connection or attachment between the petal portions and the adjacent shaft, this result being obtained by simple means. For this purpose, whereas the rest of the member (the raceways, bottom, cavities for the attachment of members effecting an axial retention) is carburized or carbonitrided, the connection regions are substantially devoid of any carburizing or carbonitriding.
