Abstract
The invention discloses a surface annealing treatment bearing. The surface annealing treatment bearing comprises a bearing outer ring and a bearing inner ring, wherein a rolling ball is arranged between the bearing outer ring and the bearing inner ring; the bearing inner ring is radially provided with a lubricating channel, and is axially provided with a lubricating hole. The surface thermal treatment process of the bearing comprises the following steps: (1) putting the bearing into a heating furnace, then filling the heating furnace with inert protective gases, and then raising the temperature of the heating furnace to 500-600 DEG C; (2) cooling the temperature in the heating furnace at the speed of 80 DEG C/hour to 120-180 DEG C; and (3) taking out the bearing, and cooling naturally to normal temperature.
Description
Technical field
The present invention relates to field of bearings, specifically, be related specifically to a kind of bearing of flash annealing process.
