发明名称 METHOD FOR PRODUCING THE ROLLING ELEMENTS OF A BALL ROLLER BEARING
摘要 A method for producing, ball rollers. The following method steps are performed to produce the ball rollers: (A) cutting unfinished sections at a defined length from a round wire that has a defined diameter, (B) compression molding ball roller blanks that have end face depressions in the form of a die tool, and (C) grinding the ball roller blanks to the desired final dimensions in a ball grinding machine. The cut-off unfinished sections have a volume by which during compression molding an approximately tangential raceway transition from one ball roller half to the other ball roller half and material fibers extending under the running surfaces of the ball rollers parallel or approximately parallel to the running surfaces arise. In addition, the ball roller blanks are ground to the final dimensions in a horizontal ball grinding machine loaded exclusively with ball roller blanks of the same size.
