Title
(EN) Thin slide unit
(ZH) 薄型滑动单元
Abstract
(EN)
A thin slide unit where an endless circulation path for balls is constructed by combining two ball plates having track-like ball grooves formed in them, wherein the balls are smoothly circulated in the unit constructed only by directly joining the two ball plates without use of a guide plate, thereby smooth reciprocation of a slider relative to a guide rail is realized. The endless ball circulation path of the slider is constructed by setting the two ball plates, having track-like grooves formed in them, opposite to each other and directly joining the ball plates together. When edge sides of the two ball plates are placed opposite to each other, a load opening for causing the balls in the endless circulation path to be in contact with a rolling groove of the guide rail is formed and, also, a scooping-up section for lifting the balls from the rolling groove to guide them into the endless circulation path is formed.

本发明提供一种薄型滑动单元,其在组装形成有轨道状滚珠槽的两片滚珠板而构成滚珠的无限循环路时,不使用导向板,仅通过直接结合这两片滚珠板就可使滚珠顺畅循环,可以实现滑动件相对导轨的顺畅往复运动。滑动件的滚珠无限循环路通过使成形有轨道状滚珠槽的两片滚珠板相互对合、并直接结合这两片滚珠板而形成,通过相互使两片滚珠板的边缘相向,形成用于使无限循环路内的滚珠与导轨的滚动槽接触的负荷开口部,同时形成把滚珠从该滚动槽中上提而引向无限循环路内的抄起部。
