Description

双滚子式内支撑回转支承
技术领域
本实用新型涉及一种双滚子式内支撑回转支承。
背景技术
回转支承是一种能够承受综合载荷的大型轴承,可以同时承受较大的轴向、径向负荷和倾覆力矩,回转支承又叫转盘轴承,有些人也称其为:旋转支撑承、 回旋支承,回转支承在现实工业中应用很广泛,被人们称为:“机器的关节”,是两物体之间需作相对回转运动,又需同时承受轴向力、径向力、倾翻力矩的机械所必需的重要传动部件。随着机械行业的迅速发展,回转支承在船舶设备、工程机械、轻工机械、冶金机械、医疗机械、工业机械等行业得到了广泛的应用。
现有技术的回转支承存在结构复杂,安装使用不方便,且载重量低等缺陷。
实用新型内容
    本实用新型提供一种载重量增大,工作稳定,噪声小的双滚子式内支撑回转支承。
本实用新型解决技术问题提供如下方案:
一种双滚子式内支撑回转支承,包括内圈、外圈,其特征在于:所述外圈的内侧壁上设有上弧形凹槽、下直角凹槽,所述外圈内设有冷却水流道,所述弧形凹槽内设有钢珠,所述直角凹槽内安装有滚子,所述内圈的外壁上设有卡槽,所述外圈安装在卡槽内,所述内圈的侧壁上连通有注油通道。
所述外圈、内圈上分别设有螺栓安装孔。
本实用新型在传统的回转支承的基础上增加了一个滚子,这样回转轴承的载重量就增大了,且这样通过这样的改进相比原先的回转支承,更加稳定,噪音小。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种双滚子式内支撑回转支承,包括内圈1、外圈2,所述外圈2的内侧壁上设有上弧形凹槽3、下直角凹槽4,所述外圈2内设有冷却水流道10,所述弧形凹槽3内设有钢珠5,所述直角凹槽4内安装有滚子6,所述内圈1的外壁上设有卡槽7,所述外圈2安装在卡槽7内,所述内圈1的侧壁上连通有注油通道8,所述外圈2、内圈1上分别设有螺栓安装孔9。
