Abstract

本实用新型提供一种通用机械零部件,具体地说是一种低阻力长寿滚珠轴承,该轴承的结构是由外轴承套、中间轴承套、内轴承套和钢珠构成,外轴承套、中间轴承套、内轴承套由外向内分层设置,钢珠分层镶嵌在外轴承套、中间轴承套和内轴承套之间。本实用新型的滑轮组轴承和现有技术相比,具有设计合理、摩擦阻力小,在机械设备中广泛使用可提高机械设备的工作效率和使用寿命,在交通车辆电动工具上使用可降低能耗等特点,因而,具有很好的推广使用价值。
The utility model provides a general mechanical part, in particular to a low-resistance long-service life ball bearing which consists of an external bearing sleeve, a middle bearing sleeve, an internal bearing sleeve and steel balls; the external bearing sleeve, the middle bearing sleeve and the internal bearing sleeve are arranged by layer from exterior to interior; the steel balls are embedded by layer between the external bearing sleeve, middle bearing sleeve and the internal bearing sleeve. Compared with the prior art, the pulley group bearing of the utility model has the characteristics of that the design is reasonable, the friction resistance is small, the work efficiency and service life of the mechanical equipment can be improved when widely applied to the mechanical equipment, the energy consumption can be reduced when applied to the traffic vehicle and electric tools, etc. Therefore, the utility model has good generalization and application value.
