Description
技术领域
本实用新型涉及电动机技术领域，具体说是一种径向密封轴向定位轴承环。
背景技术
现有的电动机轴承润滑油一般采用轴承盖密封，这就要求轴承盖内孔与转轴要配合加工，以保证二者之间的间隙，对二者的加工精度要求高，而且如果转轴与轴承盖内孔间隙过大，密封效果就不理想，经常会把轴承润滑油泄漏到电机内部，一旦电机绕组打火，容易引起润滑油燃烧发生危险。
发明内容
本实用新型的目的是为解决上述技术的不足，提供一种设计合理、结构简单、密封效果好的径向密封轴向定位轴承环。
本实用新型所采取的技术方案是：径向密封轴向定位轴承环，其特征在于设有圆环体，圆环体的内孔呈阶梯形，内孔直径从左到右依次加大，形成轴孔，轴肩孔，端盖孔。
本实用新型设计合理、结构简单，制作容易、成本低，安装、操作方便。
附图说明
图1是本实用新型的结构示意图。
图2是本实用新型的使用安装示意图。
图中标记：1.圆环体，2.轴孔，3.轴肩孔，4.端盖孔，5. 挡油板，6.挡圈，7.轴承，8.端盖,9.轴。
具体实施方式
由图1、图2可知，径向密封轴向定位轴承环，设有圆环体1，圆环体的内孔呈阶梯形，内孔直径从左到右依次加大，形成轴孔2，轴肩孔3，端盖孔4。
本实用新型安装在电机的轴承与端盖之间，圆环体1的一侧靠近轴承7，形成轴向定位，轴孔2在电机轴9上，轴肩孔3在轴肩台上，端盖孔4在端盖孔的内台上，本实用新型、端盖以及挡油板5之间形成密封体，使轴承的润滑油不能进入电机内部，使电机正常运行，对轴承实现了轴向定位，由于轴承台前端失去对轴承的直接定位作用，可使转轴9直径减小，节约了材料，降低成本。
