The invention provides a rolling bearing with blades for enhanced heat dissipation, and a design method thereof. The design method comprises the following steps: selecting a standard bearing, and obtaining the parameters of the standard bearing; thus determining the geometric parameters of a middle ring, the blades and a second inner ring of the bearing with the blades for enhanced heat dissipation, and the geometric parameters comprising an inner diameter d2, an outer diameter d3 and a thickness b2 of the middle ring, a height h, a number Z and the minimum cross-sectional area Amin of the blades, and an inner diameter d1 and a thickness b1 of the second inner ring; integrally casting and machining according to the geometric parameters of the middle ring, the blades and the second inner ring, connecting the two ends of each of the plurality of blades with the middle ring and the second inner ring respectively, then assembling the middle ring, the blades and the second inner ring with an outer ring, a rolling body and a retainer of the standard bearing, and then obtaining the rolling bearing with the blades for enhanced heat dissipation. According to the invention, on the premise of no influence on support strength, air convection is improved, and the heat dissipation of the bearing is enhanced through arrangement of the blades on the bearing.
Description
technical field [0001] The invention belongs to the field of rolling bearings, in particular to a rolling bearing with blades for enhanced heat dissipation and a design method thereof. Background technique [0002] Rolling bearings are an important general-purpose mechanical part and are widely used. Rolling bearings will generate heat even under normal working conditions. Excessive temperature rise will lead to premature fatigue failure of bearings, bearing burnout, etc., which seriously affects the service life and reliability of the entire machine. The main reasons for the temperature rise of rolling bearings are: the rolling friction between the roller and the raceway surface of the outer ring and the raceway surface of the inner ring; the sliding friction between the roller and the rib of the inner ring and the cage; the stirring resistance of the lubricant Wait. [0003] The existing bearing heat dissipation technologies mainly include: using cooling oil, water jacke...
