Description

一种变频电机轴承
技术领域
本发明属于机械辅助设备领域，具体涉及一种变频电机轴承。
背景技术
轴承（Bearing）是当代机械设备中一种重要零部件。它的主要功能是支撑机械旋转体，降低其运动过程中的摩擦系数，并保证其回转精度。按运动元件摩擦性质的不同，轴承可分为滚动轴承和滑动轴承两大类。其中滚动轴承已经标准化、系列化，但与滑动轴承相比它的径向尺寸、振动和噪声较大，价格也较高。滚动轴承一般由外圈、内圈、滚动体和保持架四部分组成，严格的说是由外圈、内圈、滚动体、保持架、密封、润滑油 六大件组成。主要具备外圈、内圈、滚动体就可定意为滚动轴承。按滚动体的形状，滚动轴承分为球轴承和滚子轴承两大类。
而众所周知，市场上许多机械设备都采用变频电机，通过变频电机自动调节转速，节省电能。由于变频电机在变频控制方便较普通电机的优越性，广泛的被应用于工农业各类机械及办公、电器设备中。而一些变频电机上使用的轴承大多数为进口轴承，对轴承的质量即低、中、高频的振动值及波形的稳定性有很高的要求。
发明内容
本发明的目的在于针对现有技术的不足，现提供一种变频电机轴承。
为解决上述技术问题，本发明采用的技术方案为：一种变频电机轴承，包括轴承外圈和轴承内圈，其创新点在于：所述轴承外圈与轴承内圈之间设有钢珠，所述钢珠的左右两侧固定安装有保持架，所述轴承外圈的正反两侧开设有环形的密封槽，所述密封槽内设安装有防水橡胶圈，所述防水橡胶圈的上方还安装有防尘罩，所述防尘罩的内端部固定安装有密封挡条，所述轴承外圈的外表面还固定安装有一耐磨层，所述耐磨层的厚度为1-3mm。
进一步的，所述防水橡胶圈与所述密封槽为镶嵌式连接。
进一步的，所述防水橡胶圈与防尘罩都安装在所述密封槽内。
进一步的，所述轴承内圈粗糙度≤0.04um，所述轴承内圈与轴承外圈的径向游隙为0.002-0.005mm。
本发明的有益效果如下：
（1）本发明具有结构简单、成本较低、使用安全、稳定性较强、噪声小、使用寿命较长的优点，通过严格控制轴承外圈、轴承内圈、钢珠之间的径向游隙范围，能增大滚动体的承载面积，使轴承能够承受较大的负荷，相对较小的径向游隙能使安装后增加支撑的刚性，减少振动和噪声，防止由于惯性力矩所引起的钢球相对于内外圈的滑动。
（2）本发明通过在防尘罩内部固定安装有一密封挡条，能够有效加强防尘罩的密封效果，并且通过在轴承外圈添加耐磨层，能够有效延长轴承的使用寿命。
