Abstract

本实用新型公开了一种滚动轴承保持架,属于轴承结构,现有保持架注脂后的油脂很难渗透到钢球与轴承沟道中,本实用新型的保持架呈环状并在其上分布球兜,相邻球兜之间有连接部,沿其轴向开设通孔,具体的,通孔分布在连接部或者球兜的底部。注脂时,把油脂注到保持架的小孔中,油脂通过小孔很容易流到轴承沟道中,这样的结构,不但提高了注脂的效率,而且还大大提高了轴承的振动、灵活性,使轴承能达到很高的寿命。

Description

滚动轴承保持架
技术领域
本实用新型涉及轴承,具体是一种滚动轴承保持架。
背景技术
在双列球轴承中,是两个独立的保持架装在一套轴承中,且保持架的端面都朝外面的,注脂成了装配成品轴承的瓶颈,一般的注脂都是注在保持架与轴承外圈内径或者是轴承内圈外径之间的缝隙里,这样的结构油脂很难渗透到钢球与轴承沟道中,即使有也很少。因此装配起来的轴承,很难达到好的振动、灵活性,轴承在使用中寿命很低(因为轴承在工作中钢球与轴承沟道很难形成油膜)。
实用新型内容
本实用新型要解决的技术问题和提出的技术任务是克服现有保持架注脂后的油脂很难渗透到钢球与轴承沟道中的缺陷,提供一种滚动轴承保持架。
为此,本实用新型的滚动轴承保持架呈环状并在其上分布球兜,相邻球兜之间有连接部,其特征是:沿其轴向开设通孔。
作为优选技术手段:所述的通孔分布在连接部,或者所述的通孔分布在球兜的底部。
本实用新型的有益效果是:把油脂注到保持架的小孔中,油脂通过小孔很容易流到轴承沟道中,这样的结构,不但提高了注脂的效率,而且还大大提高了轴承的振动、灵活性,使轴承能达到很高的寿命。
附图说明
图1是本实用新型的一种结构示意图;
图中标号说明:1-保持架,2-球兜,3-连接部,4-通孔。
具体实施方式
以下结合说明书附图对本实用新型做进一步说明。
本实用新型的滚动轴承保持架1,如图1所示,其呈环状并在其上分布球兜2,相邻球兜之间有连接部3,沿其轴向开设通孔4。具体的,通孔4分布在连接部3或者球兜2的底部。注脂时,把油脂注到保持架的小孔中,油脂通过小孔很容易流到轴承沟道中,这样的结构,不但提高了注脂的效率,而且还大大提高了轴承的振动、灵活性,使轴承能达到很高的寿命。

Claims (3)

1.滚动轴承保持架(1),其呈环状并在其上分布球兜(2),相邻球兜之间有连接部(3),其特征是:沿其轴向开设通孔(4)。
2.根据权利要求1所述的滚动轴承保持架(1),其特征是:所述的通孔(4)分布在连接部(3)。
3.根据权利要求1所述的滚动轴承保持架(1),其特征是:所述的通孔(4)分布在球兜(2)的底部。
