Description

新型套筒 技术领域
本发明五金工具技术领域，特别是涉及一种套筒。
背景技术
套筒链是一种应用广泛的重要的机械基础件，目前在重载、高速、轴向距离大等传动场合，一般都是采用套筒链，其构成包括套筒、轴销和链轮，其套筒均采用卷圆筒制造工艺制造而成，这种工艺生产的套筒真圆度无法达到，且套筒筒身存在接缝。在装配过程中，套筒筒身的接缝的朝向是随机设置的，与链轮啮合高速运转时较容易发生套筒变形、断裂，影响套筒链的使用寿命。另外现有的轴销采用圆柱形，圆柱形的轴销在使用过程中容易在套筒内转动，特别是在传递较大扭矩的情况下，导致链轮在传动或输送物品时工作不稳定，链轮磨损较厉害，减少链条的使用寿命。
发明内容
本发明主要解决的技术问题是提供一种新型套筒，提高轴销与套筒相对转动的润滑性，减少链轮的磨损，延长链轮的使用寿命。

本发明的有益效果：本发明具有提高轴销与套筒相对转动的润滑性，减少链轮的磨损，延长链轮的使用寿命的效果；
具体如下：
1、本发明套筒本体的内壁具有沿其内圆周方向绕设的一螺旋槽道，在使用时，在套筒本体的注油口加入润滑油，润滑油流经整个螺旋槽道，减少套筒本体内壁与轴销的磨损，进而减少链轮自身的磨损程度，延长链轮的使用寿命；
2、本发明套筒本体的内壁(除螺旋槽道的内壁)设有铜层，由于轴销为铁质轴销，相较于铁质轴销与铁质套筒的内壁，铜质轴销与铁质套筒摩擦力较小，减小套筒内壁与轴销的磨损；
