Abstract
A ball bearing assembly device for permitting dry assembly of bearings wiut additional equipment. The assembly device is provided with an inner body surrounded by an outer body so as to create a circumferential gap therebetween. The gap is provided with a vacuum connection which allows positioning of ball bearings on a ball bearing shaft or inner bearing ring when the shaft or ring is mounted on the inner body. The bearing shaft is placed into the inner body so as to provide a mounting to aid in insertion of the bearing shaft or ring into the outer bearing ring. The bearing shaft may be mounted on a reciprocating shaft for insertion into the outer bearing ring.
Claims18
A device for assembling an inner bearing ring into an outer bearing ring, comprising:
- means holding the inner bearing ring for assembly into the outer bearing ring;
- means attaching the inner bearing ring to said holding means including a threaded portion on said holding means adapted to extend through the inner bearing ring and a fastener associated with said threaded portion for securing the inner bearing ring to said holding means;
- means positioning a plurality of ball bearings relative to the inner bearing ring;
- means aligning the inner bearing ring with the outer bearing ring for insertion thereinto;
- and
- vacuum means affixing temporarily the plurality of ball bearings relative to the inner bearing ring.

A device for assembling an inner bearing shaft into an outer bearing ring, comprising:
- means holding the inner bearing shaft for assembly into the outer bearing ring, said holding means comprising:
- an inner body;
- a hollow outer body surrounding the inner body and having means for positioning said bearing shaft between the inner body and outer body and for attaching said bearing shaft to said inner body, and means for positioning said holding means, with the inner bearing shaft attached for insertion of the inner bearing shaft into the outer bearing ring;
- and
- means attaching the bearing shaft to the holding means, said attaching means including a threaded portion on said holding means adapted to extend through the inner bearing ring and a fastener associated with said threaded portion for securing the inner bearing ring to said holding means;
- means positioning a plurality of ball bearings relative to the bearing shaft, said positioning means being the outer body;
- and
- means affixing temporarily the plurality of ball bearings relative to the inner bearing shaft, said affixing means comprising:
- a gap means between the inner body and the outer body;
- and
- a vacuum connection to the gap.
