Description

一种滚珠丝杆
技术领域
本发明涉及一种机械零件，尤其涉及一种滚珠丝杆。 
背景技术
滚珠丝杠是将回转运动转化为直线运动，或将直线运动转化为回转运动的理想的产品，被广泛应用于各种工业设备和精密仪器。但是传统的滚珠丝杆，使用时间长后，丝杆的磨损很大，并会发热，丝杆的使用寿命会缩短，因此，需要一种新的技术方案解决上述问题。 
发明内容
本发明提供一种使用寿命长的滚珠丝杆。 
本发明采用的技术方案：一种滚珠丝杆包括螺杆、螺母和循环器，螺母固定在螺杆外侧，螺母上设有油道，螺母后端与螺杆接触处设有循环器和预压片，螺杆上设有钢珠。 
上述螺杆为高锰合金。 
本发明的有益效果：螺母上设有油道，可对丝杆进行润滑，减小摩擦对丝杆的损坏，丝杆采用高锰合金为材料，耐磨，使丝杆的使用寿命增长。 
附图说明
图1为本发明的结构示意图。 
其中，1、螺杆，2、螺母，3、循环器，4、预压片，5、钢珠，6、油道。 
具体实施方式
如图1所示，一种滚珠丝杆包括螺杆1、螺母2和循环器3，螺母2固定在螺杆1外侧，螺母2上设有油道6，螺母2后端与螺杆1接触处设有循环器3和预压片4，螺杆1上设有钢珠5。 
上述螺杆1为高锰合金。 
本发明的有益效果：螺母2上设有油道6，可对丝杆进行润滑，减小摩擦对丝杆的损坏，螺杆1采用高锰合金为材料，耐磨，使丝杆的使用寿命增长。
