Abstract

本实用新型公开了一种整体式平面推力滚针轴承。它包括有滚针和保持架组合在一起的滚动体组合件,在滚动体组合件的两侧分别安装有两片垫片,其特征是在所述的两片垫片中,其一片在内孔制有内翻边,另一片在外圆制有外翻边,在内翻边和外翻边上分别压制有至少三处向滚动体组合件扣压的压痕,将滚动体组合件和两片垫片相互间抱合形成一个整体,压制压痕后的滚动体组合件仍可在两片垫片之间灵活转动。该实用新型经压制后形成整体,在包装、运输和使用中就不会发生散失和错装、漏装的现象。当平面推力滚针轴承中的保持架受损时,由于内翻边和外翻边滚针还是被包裹在抱合的两片垫片中间,不会因滚针脱落而造成其他零件的损坏。

Description

整体式平面推力滚针轴承 
技术领域
本实用新型涉及滚针轴承,尤其涉及一种整体式平面推力滚针轴承。 
背景技术
平面推力滚针轴承是机械转动中常用的一种零件。传统的滚针轴承通常是由滚针和保持架组合在一起,组成滚动体组合件,在滚动体组合件的两侧分别配有两片单独的垫片。通常平面推力滚针轴承在出厂时必须用带子将三个零件捆扎或用袋或盒包装,工人在安装时也必须一件件的分别套在轴上,很容易造成垫片的遗失、错装或漏装。另外,当平面推力滚针轴承中的保持架受损时,滚针就会脱落,脱落的滚针就很容易造成其他零件的损坏。 
实用新型内容
本实用新型的目的是克服现有技术中存在的缺点,提供了一种结构简单,加工、安装方便的整体式平面推力滚针轴承。 
为了解决上述技术问题,本实用新型是通过以下方案实现的:它包括有滚针和保持架组合在一起的滚动体组合件,在滚动体组合件的两侧分别安装有两片垫片,其特征是在所述的两片垫片中,其一片在内孔制有内翻边,另一片在外圆制有外翻边,在内翻边和外翻边上分别压制有至少三处向滚动体组合件扣压的压痕,将滚动体组合件和两片垫片相互间抱合形成一个整体,压制压痕后的滚动体组合件仍可在两片垫片之间灵活转动。 
根据上述方案制造的整体式平面推力滚针轴承,经压制后形成整体,在包装、运输和使用中就不会发生散失和错装、漏装的现象。当平面推力滚针轴承中的保持架受损时,由于内翻边和外翻边滚针还是被包裹在抱合的两片垫片中间,不会因滚针脱落而造成其他零件的损坏。

具体实施方式
下面结合附图和具体实施例对本实用新型作进一步的描述。 
图1是整体式平面推力滚针轴承的结构示意图。从图中看出,它包括有滚针1、保持架2和上、下个两片垫片3,滚针1和保持架2组合在一起组成的滚动体组合件4如图2、图3所示,在滚动体组合件4的两侧分别安装有两片垫片3,在所述的两片垫片3中,其一片在内孔制有内翻边5,另一片在外圆制有外翻边6,在内翻边5和外翻边6上分别压制有至少三处向滚动体组合件4扣压的压痕7,压痕7将滚动体组合件4和两片垫片3相互间抱合形成一个整体如图4至图10所示,压制压痕7后的滚动体组合件4仍可在两片垫片3之间灵活转动。
