ROLLER BEARINGS PARTICULARLY SUITABLE FOR THE CAM-OPERATED CRANK ARMS OF ROTARY DOBBIES OPERATING AT VERY HIGH SPEED

摘要

A method for forming a roller bearing of very small axial dimension and high load-carrying capacity, and applicable also to a large-diameter roller bearing, comprising inserting the rollers into the circumferential guide and rolling track of the outer race and holding the rollers in position by two opposing lateral shoulder-forming spring rings of small thickness which are snap-inserted into corresponding inwardly flared grooves provided in the opposing faces of the bearing outer race. The rings being locked in position by using suitable dies to axially press annular appendices which define the mouth of the annular grooves. Modifications to this method are provided, and the roller bearings obtained in accordance with the invention are described.
