Description

一种新型高速陶瓷球轴承
技术领域    本实用新型属于滚动轴承领域，具体地说是涉及一种新型高速，采用陶瓷球作为滚动体的轴承。
背景技术    轴承广泛用于机械制造、航空航天、交通运输、能源、电力、采矿、冶金、建筑、化工、IT、家电等国防民用的几乎所有行业。滚动轴承是一种将运转的轴与轴座之间的滑动摩擦变为滚动摩擦，从而减少摩擦损失的一种精密的机械元件，用于高速旋转时的滚动轴承一般使用精密轴承。滚动轴承在高速运转的过程中，滚动体要产生离心力，离心力作用于轴承套圈，它和外加载荷一起，对套圈产生接触应力。接触应力是轴承疲劳破坏的主要原因。目前解决这一问题的办法是滚动体采用氮化硅陶瓷材料，因为氮化硅陶瓷材料的密度大约只有轴承钢的40%左右，产生的离心力也只有40%。由于氮化硅陶瓷材料特别难于加工，在生产加工过程中，技术上很难满足符合要求的球轴承。
发明内容    鉴于已有技术存在的缺陷，本实用新型的目的是要提供一种转速高，可达到极限转速，使用寿命长，耐磨的新型陶瓷球轴承。
为实现上述目的，本实用新型所采用的技术解决方案是：轴承外圈与中圈之间设有沟槽，滚动体采用陶瓷球，陶瓷球装在保持架内，并嵌入外圈与中圈之间的沟槽中；并在轴承中圈与内圈之间设有沟槽，陶瓷球装在保持架内，并嵌入中圈与内圈之间的沟槽中；中圈起到既作为内圈，又作为外圈的作用。本实用新型采用双层结构的设计，提高了轴承的转速和耐磨性，延长了轴承的使用寿命。轴承滚动体陶瓷球采用氮化硅材料，外圈、中圈和内圈采用GCr15轴承钢，保持架采用尼龙材料。
由于本实用新型具有转速高，可达到极限转速，使用寿命长，耐磨的特点，降低了企业成本，是一种具有推广价值的新产品。
附图说明
图1是本实用新型结构示意简图；
图1所示的附图标记如下：1、外圈，2、保持架，3、陶瓷球，4、中圈，5、内圈。
具体实施方式
本实用新型的具体实施方式是：轴承外圈1与中圈4之间设有沟槽，滚动体采用陶瓷球3，陶瓷球3装在保持架2内，并嵌入外圈1与中圈4之间的沟槽中；并在轴承中圈4与内圈5之间设有沟槽，陶瓷球3装在保持架2内，并嵌入中圈4与内圈5之间的沟槽中。轴承滚动体陶瓷球3采用氮化硅材料，外圈1、中圈4和内圈5采用GCr15轴承钢，保持架2采用尼龙材料。
