Abstract

本发明涉及一种向心球轴承装置，属于通用机械零件领域。为克服现有轴承不能实现轴向位移的不足，本发明公开了一种曲线圆弧沟槽的向心球轴承。将将传统球轴承的直线圆弧沟槽改为“S”形曲线圆弧沟槽，使轴承在转动的同时，能够实现往复直线运动的位移。实现上述发明的技术方案是：将原来轴承内外圈的直线沟槽变成形状完全对称的曲线沟槽，并使曲线沟槽的“峰”和“谷”的个数与钢球的个数相等，或者为钢球个数的整数倍，这样，在内外圈转动的过程中，轴在转动的同时，将做周期性往复直线运动。本发明公开的曲沟球轴承有以下优点：(1)可以将回转运动变为直线运动；(2)可以简化揉搓辊的机械结构；(3)结构简单，体积小。

Description

一种曲沟球轴承
技术领域
本发明涉及一种向心球轴承装置，属于通用机械零件领域，具体来说涉及一种曲沟球轴承。
背景技术
通用的轴承是用来定位轴类零件，使其能够灵活转动，但不能产生轴向位移的通用机械零件。但是对于需要在转动的同时，能够进行轴向位移的机构，如挤压揉搓辊的运动，通用轴承的使用将使得机构变得非常复杂。
为了简化挤压揉搓辊的机械结构，也为了将回转运动用更简单的方法变成往复直线运动，本发明公开一种曲沟球轴承。
发明内容
实现上述发明的技术方案是：将原来轴承内外圈的直线沟槽变成形状完全对称的曲线沟槽，并使曲线沟槽的“峰”和“谷”的个数与钢球的个数相等，或者为钢球个数的整数倍，这样，在内外圈转动的过程中，轴在转动的同时，将做周期性往复直线运动。具体发明内容是：
一种曲沟球轴承，由一个外圈[1]、一组钢球[2]、一组保持架[3]和一个内圈[4]构成，其特征是：所述的外圈[1]和内圈[4]镶嵌钢球的沟槽，其中至少一个为首尾相接的“S”形曲线圆弧沟槽，另一个可为直线形圆弧沟槽或者“S”形曲线圆弧沟槽；
所述的“S”形曲线圆弧沟槽的“峰”的个数和“谷”的个数都与一组钢球[2]的个数相等，或者为钢球[2]个数的整数倍；
所述的一组钢球[2]安装在外圈[1]和内圈[4]之间并用保持架[3]固定以后，钢球[2]的外沿(或内沿)之间的间距(相邻两钢球之间的距离)与外圈[1](或内圈[4])的“S”形曲线圆弧沟槽的节距(相邻两“峰”或两“谷”之间的距离)相等，或者“S”形曲线圆弧沟槽的节距为钢球[2]的外沿(或内沿)之间的间距的整数倍；
所述的一组保持架[3]，可以与内圈[4](或外圈[1])刚性连接在一体，也可以不与内圈[4](或外圈[1])刚性连接，保持游离状态；
所述的首尾相接的“S”形曲线圆弧沟槽，相邻两节沟槽之间的形状完全对称，可以是首尾相接的正玄曲线或余玄曲线，也可以是其它形状的曲线或直线。
本发明公开的曲沟球轴承有以下优点：
(1)可以将回转运动变为直线运动；
(2)可以简化揉搓辊的机械结构；
(3)结构简单，体积小。
附图说明
图1是内圈位移到左边，即钢珠在峰顶时的曲沟球轴承的结构示意图
图2是内圈位移到右边，即钢珠在谷底时的曲沟球轴承的结构示意图
图3是曲线圆弧沟槽的外圈展开后的形状示意图
图4是直线圆弧沟槽的内圈展开后的形状示意图
附图中各图例标记分别表示的意义如下：
             1-外圈，2-钢珠，3-保持架，4-内圈
具体实施方式
下面结合附图给出具体的实施例。
本发明的一个实施例是将外圈[1]做成曲线圆弧沟槽，将内圈[4]做成直线圆弧沟槽，保持架[3]与内圈[4]固定在一起转动，并使钢珠的数目与曲线的“峰”和“谷”的数目相等。这样制作的曲沟球轴承为主动摆动的曲沟球轴承。在内圈[4]为直线沟槽的曲沟球轴承中，也可以将保持架[3]做成游离状态的结构，这样结构的曲沟球轴承为被动摆动的曲沟球轴承。主动摆动的曲沟球轴承和被动摆动的曲沟球轴承配对安装，可以降低安装位置要求的精度。
也可以将外圈[1]和内圈[4]的圆弧沟槽都做成曲线结构，这样可以增加摆动幅度，同时降低安装位置要求的难度。
这些原理相同，结构上的改变都可以构成本发明的其他实施方式。
