Abstract

一种人力驱动车辆的轮轴部件,其轮轴和花盘之 间装有滚动轴承及轴承壳,轴承壳的外端面上开有环 形球槽,具有相应球槽的滚道环通过钢球与轴承壳相 连,旋在轮轴端部的调整螺母,把腔内容有滚道环的 弹性密封圈的沿口压贴在轴承壳外端面上。
与轴碗、轴挡、钢球结构的轮轴部件相比,本实用 新型具有装配简单方便、运转灵活,而且防水、防尘、 不溢油的优点。

Description

本实用新型属于B60B小类,特别与人力驱动的车辆,例如自行车、三轮车、手推车等等的轮轴部件有关。
在公知公用的人力驱动的车辆中,轮轴部件一般的结构为:轴管的两端各压合一个花盘,花盘内置有轴碗,轴碗内放有钢球及润滑油,轴棍穿入轴管后其两端各旋装着一个轴挡、垫片和螺母。多数的轴挡不带翼环,因此还要在轴挡和花盘之间加装防尘盖。这种结构的轮轴,不仅装配要求较高,否则不是“咬死”,就是车轮晃动;而且密封性能较差,润滑油易外溢,雨水与灰尘、泥沙很易进入。
本实用新型的任务是提供一种人力驱动车辆的轮轴部件,它的装配要求低,密封性能好,运转灵活。
任务由下述方案得以实现:
轮轴与花盘之间装有滚动轴承和轴承壳。轴承壳的外端面上开有环形球槽。开有相应环形球槽的滚道环通过钢球与轴承壳连在一起。调节螺母通过螺纹与轮轴配合,把弹性密封圈的沿口压贴到轴承壳的外端面上并把滚道环罩在圈腔内。轴承壳另一面可以加装垫片,抵住花盘腔的底部。此外还包括与车架固定用的螺母及垫片。
按照上述方案制成的样品,经发明人试用,证明该轮轴部件具有装配调整简单方便,运输轻松灵活的优点,在重负载时效果更为明显。此外,还具有防水、防尘以及不发生润滑油外溢即密封性能好的优点。
附图为本实用新型的一个实施例的示意图。
下面结合附图描述实施例:在轮轴[1]上套入垫片[8],然后装上滚动轴承[7],本例为滚针轴承。再推入轴承壳[6],连同装在壳腔内的滚动轴承[7]、垫片[8]一起装在花盘腔内,此时轮轴[1]早已穿入轴管。然后在轴承壳[6]外端面的环形球槽上排满近一圈的钢球[5],涂布润滑油,开有相应球槽的滚道环[4]通过钢球[5]与轴承壳[6]连接。弹性密封圈[3](本例为橡塑密封圈)罩住滚道环[4],其沿口与轴承壳[6]外端面紧密接触,最后在轮轴[1]的端部旋入调节螺母[2],以调整弹性密封圈[3]与轴承壳[6]的接触紧密与否。安装到车架上时,在轮轴两端各用螺母、垫片固定。
