一种高速微型轴承

High-speed miniature bearing

摘要：一种高速微型轴承，包括外圈、内圈，钢球、保持架和防尘盖；所述的保持架将钢球置于外圈和内圈之间；其特征在于：所述外圈的大圈内径6.6mm，沟深0.144mm；所述内圈的小圈外径4.0mm，沟深0.144mm；轴承的大圈曲率0.93±0.01mm，曲率系数59％；小圈曲率0.93±0.01mm，曲率系数59％。使工作中润滑脂更加容易进入轨道面与钢球，增加润滑，使工作热量更易散发出去，避免过量温升对钢球的损坏。保证了轴承在高温环境下的稳定工作，延长了寿命。
Abstract： The utility model discloses a high-speed miniature bearing which comprises an outer ring, an inner ring, a steel ball, a retainer and a dustproof cover, wherein the steel ball is arranged between the outer ring and the inner ring due to the retainer. The high-speed miniature bearing is characterized in that the inner diameter of a large ring of the outer ring is 6.6mm, and the groove depth is 0.144mm; the outer diameter of a small ring of the inner ring is 4.0mm, and the groove depth is 0.144mm; the curvature of the large ring of the bearing is 0.93+/-0.01mm, and the curvature coefficient is 59 percent; and the curvature of the small ring is 0.93+/-0.01mm, and the curvature coefficient is 59 percent. Therefore, lubricating grease in operation easily enters the rail surface and the steel ball, and lubrication is increased, so that the working heat is easily dissipated, and damage to the steel ball due to excessive temperature rise is avoided. Moreover, stable operation of the bearing in a high-temperature environment is guaranteed, and the service life is prolonged.
