Attachment of a hard bearing ring to the bore surface of a housing or to the lateral surface of a journal

摘要

Attachment means for mounting a first annular member such as a bearing ring having a first seating surface to a second member, such as a housing. The bearing ring has a plurality of recesses formed therein and is made of a material having a predetermined hardness. The housing has a second seating surface and a contact surface disposed angularly to the second seating surface and a fillet surface defining at least one narrow intermediate space at the juncture of the said second seating surface and contact surface. The recesses in said first seating surface open toward the internal end surface and open out into the intermediate spaces, whereas, at the end facing away from this end surface, the recesses are closed off by a boundary wall. By this arrangement, during assembly of the bearing ring in the bore of the housing or to a journal material from the housing or journal is removed to fill the recesses and thereby lock the bearing ring in place.
