Abstract: A process for producing bearing ring blanks, or gearwheel ring blanks, or tubular connection-member blanks, comprises the steps of: a) providing a steel tube; b) dividing the tube into a plurality of slugs each having an axial through cavity; c) supplying the slugs to a die assembly of a cold-forming station, the forming station including a punch assembly; and d) subjecting the slugs to contained forward extrusion through the die assembly, wherein the thrust imparted by a pushing member of the punch assembly on a subsequent slug causes passage of a preceding slug through the die assembly, with deformation thereof into a blank, while a restraining member of the punch assembly occupies the axial cavity of the subsequent slug and at least part of the axial cavity of the preceding slug.

Abstract: There is provided a method for manufacturing ring-shaped members at a good yield and high production efficiency. To achieve this object, the following is performed. A single (a sequence of) forging produces a joined body formed by radially coupling four cylindrical portions with different inner diameter sizes. A cylindrical member that has the largest inner diameter size and a cylindrical member that has the third largest inner diameter size after the forging are employed as ring-shaped members without change. A rolling process is performed on respective cylindrical member that has the smallest inner diameter size and cylindrical member that has the second largest inner diameter size to obtain ring-shaped members. Thus, two sets of ring-shaped members are obtained as two sets of inner rings and outer rings.

Abstract: In order to omit jostling caused between the adjacent rolling elements, a clearance is formed therebetween in a load region. A transfer path has a region that allows the rolling elements to contact only one of the transfer grooves of the transfer path, or a region that has a friction force acting between one of the transfer grooves of the transfer path and the rolling elements being greater than the friction force acting between another one of the transfer grooves of the transfer path and the roiling elements. The one of the transfer grooves in the region has a cross sectional shape taken in a direction perpendicular to the direction, in which the rolling elements are transferred, which cross sectional shape allowing two point contact with the rolling elements; and the rolling apparatus further has a contact-angle changing path that has a contact angle with the rolling elements that is greater than the contact angle of the other portion of the transfer path. Thus, the orbital motion speed of the rolling elements is changed.
