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.

A method for the assembly of universal joints with radially pretensioned fork arms, consisting of the steps of inserting and positioning the joint cross in the joint fork, pressing in the bearing and fixing them by means of pressure units, one of which supports each fork arm and pretensioning each fork arm individually during the entire pressing-in and/or fixing phase by means of the tipping force resulting from the pressure prevailing between the support element and the pressing/peening tool, reduced by a partial force following in response to the amount of the pressing force.

Process and apparatus for assembling universal joints

A locking device for maintaining the split inner ring of a bearing in assembled relation during shipment and handling prior to installation. The locking device is of generally rectangular shape and is made of a resilient elastically deformable material so that it is readily inserted and removed from the inner ring bore. When seated in place it exerts a clamping action in a radial direction by spring action and contacts in the bore of both inner ring parts of the bearing.
