Self-aligning roller bearing retainer for brass entity, and forming method of retainer

The invention relates to a self-aligning roller bearing retainer for a brass entity. The self-aligning roller bearing retainer comprises a retainer body which is integrally formed by machining. The self-aligning roller bearing retainer is characterized in that the retainer body is internally provided with two rows of roller mounting holes which are evenly distributed in a staggered way; the retainer body comprises an intermediate ring and an internal shell nosing cone which extends towards two sides symmetrically from the intermediate ring; the plurality of roller mounting holes are evenly machined in the circumferential direction of the internal shell nosing cone; the axes and the normals of the roller mounting holes intersect at one point; and rollers are arranged in the roller mounting holes and can be used for guiding the retainer independently. The self-aligning roller bearing retainer for the brass entity has the advantages of high bearing load, low noise and vibration, high stability, self-lubrication and self-guiding by the rollers.
