This invention relates to an oil film-deposit bearing, the oil film-deposit bearing being composed of an outer ring, an inner ring and a plurality of rolling means, the inner circumference of the outer ring and the inner ring having respectively an arc groove, on the surface of the arc grooves having a plurality of capillary holes, the rolling means being installed between the arc grooves of the outer ring and the inner ring and can roll between them, on the outer surface of the rolling means having a plurality of capillary holes, the oil or grease added on the contacting surface between the rolling means and the arc grooves would deposit in these capillary holes, once the oil film-deposit bearing rotating with shaft, the oil or grease deposited in the capillary holes would flow out to form an oil film on the contacting surface between the rolling means and the arc grooves, thus the oil film-deposit bearing can lubricate itself and prevent the oil or grease from throwing out in high speed rotation. |
