Description

一种绝缘深沟球轴承
技术领域
本发明属于轴承结构领域，具体涉及一种能防止轴承在使用过程中遭受轴电压破坏的轴承内圈内径注塑有PEEK材料的绝缘深沟球轴承，主要用于电机、空压机等领域。
背景技术
轴承是一种应用在转动机构上，用来支撑，减少摩擦以及承受负载的部件。该产品主要为用于电机、空压机等机械而设计，由于可以绝缘，尤其是转速较高易产生轴电压的场合，装拆简单，承载能力很强，成本很低的场合。因而适用于易产生轴电压的电机和空压机等机械。目前，国内该场合主要采用陶瓷轴承、内径或者外径镀层来满足绝缘需求，但该类轴承成本较高。
发明内容
本发明所要解决的技术问题是：针对现有绝缘轴承成本较高，提供一种低成本、转速较高、装拆方便、预防打滑、较高寿命的轴承内圈内径注塑有PEEK材料的绝缘深沟球轴承。
为实现本发明之目的，采用以下技术方案予以实现：
一种绝缘深沟球轴承，包括外圈、内圈以及滚动安装在外圈和内圈之间的多个钢球，所述多个钢球安装在一个保持架上；
所述外圈内壁成型有外沟道，其余外圈内壁部分则成型为外内径；
所述内圈外壁成型有内沟道，其余内圈外壁部分则成型为内外径；所述内圈的侧面与外圈的侧面表面平齐；
在内圈内壁上设有PEEK注塑层，且PEEK注塑层的侧面低于内圈的侧面。
较佳地，在所述内圈内壁上向内突出形成有凸条，PEEK注塑层注塑在内圈内壁和凸条上。
较佳地，所述内圈内壁与凸条的交接处开有止动槽。
较佳地，所述保持架沿周向均匀地成型有多个兜孔，保持架上位于两相邻兜孔之间为铆钉连接，保持架上均匀的分布大小一致的球窝。
较佳地，所述保持架采用08#或10#材料冲压成型加工。
与现有技术相比较，本发明的有益效果是：
①在轴承内圈内径注塑PEEK材料，成本很低；②由于轴承内圈内径注塑PEEK材料，能够实现产品的大批量生产，生产效率大大提高；③由于轴承内圈内径注塑PEEK材料，在生产过程中能够很好实现大批量的自动磨削；④由于PEEK材料密度远小于同等规格的轴承钢，因此，该注塑的轴承能够承受较高的转速。

具体实施方式
下面根据附图对本发明的具体实施方式做一个详细的说明。
根据图1至图6所示，本实施例所述的一种绝缘深沟球轴承，包括外圈1、内圈2以及滚动安装在外圈1和内圈2之间的多个钢球3，多个钢球3安装在一个保持架4上；外圈1内壁成型有外沟道5，其余外圈1内壁部分则成型为外内径6；内圈2外壁成型有内沟道7，其余内圈2外壁部分则成型为内外径8；内圈2在轴向方向上的侧面与外圈1在轴向方向上的侧面表面平齐；在内圈2内壁上设有厚度在0.5mm-1.5mm之间的PEEK注塑层9，且PEEK注塑层9在轴向方向上的侧面低于内圈2在轴向方向上的侧面；为了进一步防止PEEK注塑层9的滑动，在内圈2内壁上向内突出形成有凸条12，PEEK注塑层9注塑在内圈2内壁和凸条12上，并且内圈2内壁与凸条12的交接处还开有止动槽10。
上述的保持架4沿周向均匀地成型有多个兜孔，保持架4上位于两相邻兜孔之间为铆钉11连接，保持架4上均匀的分布大小一致的球窝，这里的兜孔与钢球3之间接触为单点接触型；保持架4由08#材料冲压成型加工，冲压加工及轴承装配均很方便，效率较高。
该轴承内圈内径注塑PEEK材料的绝缘深沟球轴承装配时，先将钢球3装入轴承内沟道7和外沟道5间，测量游隙值，合格后再均匀的将钢球3分散在内沟道7和外沟道5间，再合上保持架4后，送至冲床上冲压。至此，一套内径注塑PEEK材料的绝缘深沟球轴承装配完毕。
