Abstract
A ball bearing is constructed by snap fitting a first section of an outer race to an inner race so that such first section can rotate on the inner race. Balls are operatively positioned in relation to the first section of the outer race and the inner race and a second section of the outer race similarly snap fitted to the inner race so as to be rotatable relative thereto. The first and second sections subsequently are secured together, and this has the effect of firmly positioning the outer race on the balls and clear of the inner race so as to be rotatable freely relative thereto.
Claims5
A method of constructing a ball bearing device which is composed of an inner race, ball bearings, and an outer race composed of two separate sections of plastics material, which method comprises:
- a. snapping a first section of said outer race into a retained operative position around said inner race so that said first section can rotate freely about said inner race,
- b. disposing said first section of said outer race in a generally horizontal plane and depositing in said horizontally disposed first section a plurality of balls so that said balls engage the race surfaces of said inner race and said first section of said outer race,
- c. snapping the other outer race section into retained operative position around said inner race so that said other outer race section can rotate freely on said inner race, and thereby trapping said plurality of balls in a cavity jointly defined by said two sections of the outer race,
- d. securing said two sectins of said outer race firmly together so that said two sections of said outer section are firmly in contact with the balls and free of contact with said inner race.
