Abstract
A cage for an antifriction bearing is an elongate strip of injection molded plastic in the form of individual cage sections. Each section has lateral sides and cross webs which together define a pocket for a respective bearing rolling element. Adjacent cage sections are connected by thin strip connecting webs which are of a length to define an open space between adjacent sections. Respective connecting hooks are defined at the cross webs of each cage section. Following separation of two sections by breaking the connecting webs therebetween, the sections can be later reconnected for defining a complete circular cage by hooking the respective hooks at the cross webs of the neighboring sections to each other.
Claims10
A cage for an antifriction bearing, comprising:
- individual sections each for holding a respective rolling element, the individual sections being connected one after the other to define a complete cage for a circular row of rolling elements for the bearing;
- each section of the cage comprising opposite lateral sides which extend along the circumferential direction of the completed cage and also comprising cross webs extending across the section and joining the lateral sides, the lateral sides and the cross webs being placed for defining between them an open pocket for receiving a respective rolling element;
- respective connecting webs being defined at the ends of each section at the cross webs for joining the adjacent sections of the cage, thereby to define a complete cage;
- the connecting webs between adjacent sections being separable for separating adjacent segments;
- respective connecting means defined on the cross webs of the sections and the connecting means on one cross web of one section being connectable with the respective connecting means on the adjacent cross web of the neighboring section for reconnecting the neighboring sections at their respective cross webs after those neighboring sections have been separated by separation of their respective connecting webs
- the cage being comprised of moldable material and the entire cage being molded.
