Description

technical field [0001] The invention relates to the field of bearing structure design, and mainly aims at small and miniature self-aligning roller bearings and a preparation method. Background technique [0002] Spherical roller bearings usually use spherical rollers to cooperate with spherical raceways to form a rotary self-aligning structure. At present, spherical roller bearings adopt this structure. When the use environment requires the outer dimension of the bearing to be small, the structural space of the spherical roller bearing will be limited. At this time, the processing difficulty of traditional self-aligning bearing parts increases due to structural limitations, and the strength of the parts also decreases. Contents of the invention [0003] The purpose of the present invention is to solve the problem of poor strength of existing traditional self-aligning bearing parts, and provide a self-aligning roller bearing with a concave surface structure and a preparat...
