Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing rings, in particular to a high-efficiency heat dissipation bearing ring. Background Art
[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Early linear motion bearings were a row of wooden poles placed under a row of pry plates. Today's linear motion bearings use the same working principle, but sometimes balls are used instead of rollers. The simplest rotary bearing is a sleeve bearing, which is just a bushing sandwiched between the wheel and the axle. This design was later replaced by rolling bearings, which replace the original bushing with many cylindrical rollers, and each rolling element is like a separate wheel.
[0003] However, the prior art still has shortcomings. In the prior art, the heat dissipation effect of traditional bearing rings is poor, and the bearing rings cannot be quickly and efficiently cooled. When the bearing is in operation, the roller will roll on the inner wall of the bearing ring, and a lot of heat will be generated during the rolling process. If the heat is not dissipated in time, the service life of the bearing will be seriously shortened.
[0004] Therefore, we propose a high-efficiency heat dissipation bearing ring to solve this problem. Utility Model Content
[0005] The utility model aims to solve the problems raised in the above-mentioned background technology and proposes a high-efficiency heat dissipation bearing ring.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A high-efficiency heat dissipation bearing ring comprises an outer ring, an inner ring and a ball; the inner arc surface of the outer ring is provided with a No. 1 groove; the outer cylindrical surface of the inner ring is provided with a No. 2 groove; the ball is slidably mounted on the inner arc surface of the No. 1 groove; the ball is slidably mounted on the outer cylindrical surface of the No. 2 groove; the outer surfaces on both sides of the outer ring are provided with a No. 1 groove; the outer surfaces on both sides of the inner ring are provided with a No. 2 groove; the outer surface of one side of the No. 1 groove is provided with a No. 1 heat dissipation hole; the outer surface of one side of the No. 2 groove is provided with a No. 2 heat dissipation hole; a small fan blade is fixedly connected to the outer surface of one side of the No. 1 groove.
[0008] Preferably, the small fan blades are evenly located between the No. 1 heat dissipation holes.
[0009] Preferably, the small fan blades are evenly fixed to the outer surface of one side of the No. 1 groove.
[0010] Preferably, the No. 1 heat dissipation holes are evenly distributed in the No. 1 groove.
[0011] Preferably, the second heat dissipation holes are evenly distributed in the second groove.
[0012] Preferably, the balls are evenly distributed between the outer ring and the inner ring.
[0013] In the utility model, the high-efficiency heat dissipation bearing ring is provided with an outer ring, an inner ring, a No. 1 groove, a No. 1 heat dissipation hole, a No. 2 groove, a No. 2 heat dissipation hole, a ball, a No. 1 slot, and a No. 2 slot. The rotation of the outer ring and the inner ring will drive the No. 1 heat dissipation hole and the No. 2 heat dissipation hole to rotate. The friction between the ball and the outer ring and the inner ring will cause the outer ring and the inner ring to heat up. The air in the No. 1 heat dissipation hole and the No. 2 heat dissipation hole will expand due to the heat, so that the air in the No. 1 heat dissipation hole and the No. 2 heat dissipation hole will leave the No. 1 heat dissipation hole and the No. 2 heat dissipation hole, so that the air pressure in the No. 1 heat dissipation hole and the No. 2 heat dissipation hole is lower than the outside air pressure, so that the outside air enters the No. 1 heat dissipation hole and the No. 2 heat dissipation hole, thereby cooling and dissipating the outer ring and the inner ring, and realizing heat dissipation of the bearing.
[0014] In the utility model, the high-efficiency heat dissipation bearing ring is provided with small fan blades, and the rotation of the outer ring drives the small fan blades to rotate. The rotation of the small fan blades reduces the air pressure on one side of the outer ring, so that the air on the other side of the outer ring is squeezed to the other side of the outer ring, and the air passes through the first heat dissipation hole and the second heat dissipation hole, thereby dissipating the heat to the outer ring and the inner ring;
[0015] The utility model has reasonable structural design, simple operation and high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
