Description

高精度成对安装圆锥滚子轴承
技术领域
本发明涉及一种主要应用于机床行业，使用于精镗床主轴的高精度成对安装圆锥滚子轴承。
背景技术
传统的精镗床主轴轴承原采用成对安装圆锥滚子轴承，来承受径向和轴向载荷。由于该轴承故有的结构缺陷，圆锥外圈机床法兰装配后，为了保证法兰与轴承外圈的同轴度，需要对其隔圈进行修磨，从而改变其初始游隙，而导致轴承游隙过大或过小，当游隙过小时，机床主轴发热量大；当游隙过大时，影响主轴旋转精度，产生“蹦刀”现象。
发明内容
为了克服轴承精度、游隙等问题，本发明提供了一种特殊游隙的高精度成对安装圆锥滚子轴承。
本发明的技术方案是：高精度成对安装圆锥滚子轴承，包括高精度外圈1、保持架2、滚子3、外隔圈4、内隔圈5和内圈6，保持架2、滚子3、和内圈6组成轴承内组件，将外圈1装入内组件中组成轴承，外圈1之间设有外隔圈4，内圈6之间设有内隔圈5，外圈1和内圈6为椭圆形，控制内圈6椭圆和外圈1椭圆相互差在正常国标的1/2，以更好的保证客户轴与壳体的配合，再经过有限元模拟工况和经验，将游隙公差范围压缩到正常国标的1/3，以适合的客户特殊需要；保持架2的兜孔内设有两对成对的退刀槽I和退刀槽II，以控制轴承的噪音与跳动，退刀槽I和退刀槽II的斜坡角c为45°，退刀槽I的圆弧半径R1和退刀槽II的圆弧半径R是圆锥滚子两端面半径的3％～5％，根据退刀槽I的圆弧半径R1确定退刀槽I的径向尺寸a1和轴向尺寸b1，根据退刀槽II的圆弧半径R确定退刀槽II的径向尺寸a和轴向尺寸b。
本发明的有益效果是：不仅很好的满足径向和轴向精度要求，而且还很好地解决了客户安装时的游隙改变等问题。

具体实施方式
下面结合附图对本发明做进一步详细说明。
如图1所示，高精度成对安装圆锥滚子轴承，包括高精度外圈1、保持架2、滚子3、外隔圈4、内隔圈5和内圈6，保持架2、滚子3、和内圈6组成轴承内组件，将外圈1装入内组件中组成轴承，外圈1之间设有外隔圈4，内圈6之间设有内隔圈5，外圈1和内圈6为椭圆形，控制内圈6椭圆和外圈1椭圆相互差在正常国标的1/2，以更好的保证客户轴与壳体的配合，再经过有限元模拟工况和经验，将游隙公差范围压缩到正常国标的1/3，以适合的客户特殊需要。如图2所示，保持架2的兜孔内设有两对成对的退刀槽I和退刀槽II，以控制轴承的噪音与跳动，退刀槽I和退刀槽II的斜坡角c为45°，退刀槽I的圆弧半径R1和退刀槽II的圆弧半径R是圆锥滚子两端面半径的4％，根据退刀槽I的圆弧半径R1确定退刀槽I的径向尺寸a1和轴向尺寸b1，根据退刀槽II的圆弧半径R确定退刀槽II的径向尺寸a和轴向尺寸b。
