Abstract

本实用新型公开了一种高精度长圆柱滚子轴承，用于商场、生产流水线搬运物品所用手推车滚轮的支撑，包括保持架和滚子，滚子可滚动环形均布在保持架上，所述的滚子外围设有拉伸外壳，拉伸外壳内表面与滚子滚动接触。本实用新型在常用的长圆柱滚子轴承的滚子外围设置拉伸外壳，采用拉伸工艺制作精度较高，轴承安装在铝制轮毂上后，拉伸外壳的外表面与轮毂可以实现较高精度的配合，也防止了以往滚子直接与轮毂滚动接触而造成铝制轮毂的磨损。

Description

高精度长圆柱滚子轴承
技术领域
本实用新型涉及轴承技术领域，尤其是一种用于商场、生产流水线搬运物品所用手推车滚轮支撑的高精度长圆柱滚子轴承。
背景技术
手推车被普遍应用于超市、商场以及生产流水线上，手推车所用脚轮轮毂既有采用铁质材料制作，也有选用铝材制作的，一般的长圆柱滚子轴承的滚子与轮毂面是直接接触的，由于铝材相对铁质材料来说较软，铝材制作的轮毂使用时容易受到滚子转动的所造成的磨损，同时铝制轮毂装配精度要求较高。
实用新型内容
本实用新型要解决的技术问题是：克服现有技术中之不足，提供一种高精度长圆柱滚子轴承，以提高轴承装配精度，防止使用时轴承滚子转动对铝制轮毂造成的磨损。
本实用新型解决其技术问题所采用的技术方案是：一种高精度长圆柱滚子轴承，包括保持架和滚子，滚子可滚动环形均布在保持架上，所述的滚子外围设有拉伸外壳，拉伸外壳内表面与滚子滚动接触。
本实用新型的有益效果是：本实用新型在常用的长圆柱滚子轴承的滚子外围设置拉伸外壳，采用拉伸工艺制作精度较高，轴承安装在铝制轮毂上后，拉伸外壳的外表面与轮毂可以实现较高精度的配合，也防止了以往滚子直接与轮毂滚动接触而造成铝制轮毂的磨损。
附图说明
下面结合附图和实施方式对本实用新型进一步说明。
图1是本实用新型的结构示意图。
图中1.保持架；  2.滚子；  3.拉伸外壳。
具体实施方式
现在结合附图对本实用新型作进一步的说明。这些附图均为简化的示意图仅以示意方式说明本实用新型的基本结构，因此其仅显示与本实用新型有关的构成。
如图1所示的一种高精度长圆柱滚子轴承，用于商场、生产流水线搬运物品所用手推车滚轮的支撑，包括保持架1和滚子2，滚子2可滚动环形均布在保持架1上，所述的滚子2外围设有拉伸外壳3，拉伸外壳3内表面与滚子2滚动接触。由于拉伸外壳3采用拉伸工艺获得，其外表面具有较高的精度，因此当这种具有拉伸外壳3的轴承安装在脚轮的铝制轮毂上后，拉伸外壳3的外表面与轮毂之间可以获得较高的配合精度，从而提高装配精度，同时也防止了以往滚子2直接与轮毂滚动接触而造成铝制轮毂的磨损。
上述实施方式只为说明本实用新型的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本实用新型的内容并加以实施，并不能以此限制本实用新型的保护范围，凡根据本实用新型精神实质所作的等效变化或修饰，都应涵盖在本实用新型的保护范围内。
