Abstract

组合式直线轴承由保持架和滑动模组成。保持架中段内壁圆周上制有限位槽,槽底有限位孔。滑动模至少有塑料薄板,其与限位槽配合处的两面制有宽度小于等于限位槽并间隔分布的限位凸台,其中至少一个凸台上的限位销。组装时卷起并将限位销塞入限位孔,让其弹开覆贴在内壁上。更换时相反。本实用新型可用于灰尘杂物较多的环境,排屑作用强,制造维护简单,成本低、无噪音。

Description

组合式直线轴承
所属技术领域
本实用新型在国际专利分类中,属于轴、轴承小类,即F16C。特别涉及组合式直线轴承。
背景技术
众所周知,直线轴承有三层复合轴承、润滑材料镶嵌式轴承和滚动体与保持架镶嵌轴承。前两者润滑性能欠佳而且寿命短;后者无润滑性能,需要加注油脂,易污染、难更换。所有已知直线轴承均不适用灰尘杂物较多的环境。
实用新型内容
本实用新型的目的在于解决直线轴承可在灰尘杂物环境使用的难题。
该难题通过下列方案得以克服:组合式直线轴承包括保持架和滑动模。所说保持架的中段内壁圆周上制有限位槽,槽底至少制有一个限位孔;所说滑动模包括塑料薄板,其与保持架中限位槽的配合处,制有均匀间隔分布在薄板两面的限位凸台,其中至少一个限位凸台上,有与限位孔配合的限位销。
按上述方案试制的组合式直线轴承,由于间隔分布的限位凸台有排屑作用,因此可在灰尘杂物较多的场合使用,它制造容易,组装简便,成本较低,维护更换方便。
附图说明
图1为本实用新型轴剖示意图。其中1为保持架,2为滑动模。
图2为图1的A-A剖视示意图。
图3为保持架轴剖示意图。其中3为限位孔,4为限位槽。
图4为图3的B-B剖视示意图。
图5为滑动模示意图。其中5为限位凸台。
图6为图4的左视图。其中6为限位销。
图7为滑动模内部结构示意图。
具体实施方式
组合式直线轴承由圆管状的保持架1和覆贴内壁的滑动模2组成。保持架1优选金属材料,不排除工程塑料或复合材料。保持架1的中段内壁圆周上制有限位槽4,槽底至少制有一个限位孔3,以与外壁相通为宜。滑动模2由塑料薄板和限位凸台5、限位销6组成。塑料薄板与保持架1上的限位槽4的配合处两面,制有均匀间隔分布在薄板两面的限位凸台5,其中至少一个限位凸台5上制有与限位孔3配合的限位销6。限位凸台5的宽度等于或略小于限位槽4。滑动模2由工程塑料加无机、有机改进剂、增强纤维、润滑物混合注塑成型。组装时,卷起滑动模2,放入保持架1内,限位销6塞入限位孔,然后张开滑动模2,此时限位凸台5进入限位槽4,覆贴在保持架1的内壁上,维修更换时,与组装程序相反。
