Description

一种轧钢机压下机构专用的满装推力圆锥滚子轴承
技术领域
 本实用新型涉及轧钢机压下机构中使用的轴承领域，具体的讲是涉及一种轧钢机压下机构专用的满装推力圆锥滚子轴承。
背景技术
轴承在各行各业的设备和器具上都得以广泛的使用，针对设备结构的特点、轴承预计承载的负荷以及使用环境等实际应用情况，轴承的品种型号也呈现多种多样，应有尽有。满装推力圆锥滚子轴承就属于轴承的一个系列，目前较为通用的满装推力圆锥滚子轴承虽然能承受较大的轴向载荷，但在底圈和顶圈上普遍采用直接加工有吊装螺纹孔，虽然可以满足安装功能的要求，但是容易产生轴承零件潜伏应力集中，降低轴承的使用寿命，同时热处理淬火容易使轴承产生裂纹。
发明内容
鉴于已有产品存在的缺陷，本实用新型是要提供一种轧钢机压下机构专用的满装推力圆锥滚子轴承。
为实现上述目的，本实用新型一种轧钢机压下机构专用的满装推力圆锥滚子轴承，其特征在于：由顶圈、顶圈弹簧圈、顶圈吊装螺母、圆锥滚子、底圈、底圈弹簧圈和底圈吊装螺母构成。底圈和顶圈中间设有滚道，圆锥滚子满装于滚道中。顶圈设有顶部镶嵌螺纹套，底圈设有底部镶嵌螺纹套，顶圈和底圈通过镶嵌螺纹套固定在一起。
所述顶部镶嵌螺纹套是由顶圈弹簧圈和顶圈吊装螺母构成的，顶圈弹簧圈设在顶圈吊装螺母上。
所述底部镶嵌螺纹套是由底圈弹簧圈和底圈吊装螺母构成的，底圈弹簧圈设在底圈吊装螺母上。
本实用新型与现有产品相比，具有以下突出优点和积极效果：
1、本实用新型无保持架，圆锥滚子满装滚道，能承受较大的单向轴向负荷，因而在压下机构相对轴承轴线产生一定倾斜时能保证轴承受力均匀，同时也适用于低速要求承受单向轴向载荷特别大的运动机构。      2、本实用新型在底圈和顶圈的结构上有很大的改进，传统产品，在这两个轴承零件上直接加工的吊装螺纹孔取消，采用镶嵌螺纹套的结构设计，从而即可以满足轴承安装功能的要求，同时又避免了热处理淬火可能产生裂纹及轴承零件潜伏应力集中，降低零件强度的危害，从而可以很大程度的提高轴承的使用寿命。
附图说明
图1是本实用新型结构示意图。
具体实施步骤
图1所示的附图标记如下：顶圈1、顶圈弹簧圈2、顶圈吊装螺母3、圆锥滚子4、底圈5、底圈弹簧圈6、底圈吊装螺母7。
