Abstract

本实用新型涉及一种四点接触球轴承，由轴承外圈、轴承内圈、钢球和保持架组成，保持架兜孔为两层圆柱孔，由大圆柱孔和小圆柱孔结合而成。大圆柱孔的直径为钢球的1.004倍加0.12毫米，小圆柱孔的直径小于钢球直径0.1～0.3毫米，深度为0.1－0.4毫米。小圆柱孔起锁住钢球的作用。与原轴承的保持架相比，免去手工凿印的麻烦，提高了劳动生产效率，使轴承运转更平稳，从而提高了轴承使用寿命，主要应用于机电、冶金行业，对主机进行轴向定位。

Description

自锁式四点接触球轴承
所属技术领域
本实用新型属于轴承技术领域，涉及一种四点接触球轴承，主要应用于机电、冶金行业，对主机进行轴向定位。
背景技术
目前，公知的用于四点接触球轴承车制实体保持架有两种，一种是保持架兜孔为通孔，另一种是兜孔下方为锥孔，这两种架都不理想。第一种架，手工凿印，生产效率极低有时还掉球；第二种架，球从外径装入后整体装入外圈，装球数量少，导致轴承额定动载荷低。
发明内容
为了克服四点接触球轴承常用两种保持架的缺点，即手工凿印及装球少的特点，本实用新型提供一种自锁式保持架，无须凿印，从保持架内径装球，锁量合适，装球数目多。
本实用新型的技术方案是，一种自锁式四点接触球轴承，由轴承外圈1、轴承内圈4、钢球2和保持架3组成，其特征在于，保持架3兜孔为两层圆柱孔，由大圆柱孔5和小圆柱孔6结合而成。所述的大圆柱孔5的直径D为钢球2的直径的1.004倍加0.12毫米，所述的小圆柱孔6直径d小于钢球直径0.1～0.3毫米，深度h为0.1-0.4毫米。小圆柱孔起锁住钢球的作用。成功地解决了装轴承时钢球易从保持架内径掉出的问题。
本实用新型的有益效果是，与原保持架相比，免去手工凿印的麻烦，提高了劳动生产效率，使轴承运转更平稳。提高了额定动载荷和轴承使用寿命。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型的组装结构示意图。
图2是本实用新型的保持架的结构示意图。
图3是本实用新型的保持架的A-A剖视结构示意图。
图中，1、轴承外圈，2、钢球，3、保持架，4、轴承内圈，5、大圆柱孔，6、小圆柱孔。
具体实施方式
保持架3兜孔为两层圆柱孔，由大圆柱孔5和小圆柱孔6结合而成。大圆柱孔5的直径D为钢球2的1.004倍加0.12毫米，所述的小圆柱孔6直径d小于钢球直径0.1～0.3毫米，深度h为0.3毫米。小圆柱孔起锁住钢球的作用。因四点接触球轴承内圈两体，用户在装轴承时钢球易从保持架内径掉出，给安装带来许多困难。用自锁式保持架就成功地解决了这个问题。
