Description

带有滚动摩擦组件的滚动轴承
技术领域
本发明专利涉及一种滚动轴承，具体涉及带有滚动摩擦组件的滚动轴承。
背景技术
现有带保持架的低摩擦力矩滚动轴承按结构主要分为球轴承和圆柱滚子轴承，其保持架引导方式主要有滚动体引导、外圈引导、内圈引导。外圈引导和内圈引导方式与滚动体引导方式相比，具有更低的摩擦力矩。
现有外圈引导和内圈引导方式的保持架，与套圈引导面做滑动运动，相对滚动运动方式，摩擦力矩更大。随着现代科技的进步，以及传动设备的发展需求，因此轴承的低摩擦力矩不断的进行改进，需要研发低摩擦力矩的滚动轴承。
发明专利内容
本发明专利的目的是根据现有技术传动设备的发展需求，需要研发低摩擦力矩的滚动轴承，进而提供带有滚动摩擦组件的滚动轴承。
本发明专利为解决上述问题而采用的技术方案是：
它包括轴承外圈、轴承内圈、保持架和多个滚动体，它还包括滚动摩擦组件；轴承外圈和轴承内圈同心位置，多个滚动体在外圈和内圈之间起到支撑作用，并使外圈和内圈保持同心，，保持架设置在轴承外圈和轴承内圈之间，将多个滚动体等距隔开，多个滚动体通过保持架与轴承外圈和轴承内圈滚动连接，保持架的外圆面与轴承外圈之间通过滚动摩擦组件滚动连接。
发明专利的有益效果是：
1、本申请与现有技术相比，通过在保持架3上保持架滚动兜槽，安装引导面滚动体，使保持架3相对套圈的运动方式由滑动变为滚动，降低轴承的摩擦力矩。
2、本申请将导面滚动体以满球形式装在保持架3上保持架滚动兜槽内，多个引导面滚动体沿圆周方向均布设置，使保持架相对套圈的运动方式由滑动变为滚动。保证滚动轴承的保持架3与轴承外圈1每个位置受力均匀。
3、本申请通过在保持架3外圆面上设置每保持架滚动槽，并安装引导面滚动体，使保持架3相对轴承外圈1的运动方式由滑动变为滚动，降低轴承的摩擦力矩。轴承启动力矩可以降低25％以上，轴承运转力矩可以降低60％以上，轴承振动加速度可以降低35％以上，轴承打滑率可以降低30％以上，轴承寿命可以提升160％以上，轴承维护成本可以减少40％以上。
附图说明

图2是现有技术中滚动轴承引导面为滑动摩擦的滚动轴承示意图。
图3是本申请中引导面为圆球体的球轴承。
图4是本申请中引导面为圆球体的圆柱滚子轴承。
