Description
技术领域technical field
本发明属于高速轴承技术领域，尤其是一种具有自动清洁功能的动压滑动轴承装置。The invention belongs to the technical field of high-speed bearings, in particular to a dynamic pressure sliding bearing device with automatic cleaning function.
背景技术Background technique
轴承在运转条件下需要良好的润滑，特别是高速轴承，如用于计算机硬盘高速电机的含油轴承，动压滑动轴承等。含油轴承通过含油材料对轴承提供润滑油来实现润滑，这些润滑随着长期使用会逐渐变差，主要原因：高速运转条件下轴承温度升高，润滑油粘度下降，效果变差，加速润滑油变质；轴承自身磨损或外界粉尘渗入润滑油中，使轴承润滑条件变差，甚至进一步加剧轴承的磨损，降低轴承的使用寿命。Bearings need good lubrication under operating conditions, especially high-speed bearings, such as oil-impregnated bearings for computer hard disk high-speed motors, dynamic pressure sliding bearings, etc. Oil-containing bearings provide lubricating oil to the bearings through oil-containing materials to achieve lubrication. These lubrications will gradually deteriorate with long-term use. The main reason is that the temperature of the bearings increases under high-speed operating conditions, the viscosity of the lubricating oil decreases, the effect becomes worse, and the deterioration of the lubricating oil is accelerated. ; The wear of the bearing itself or the infiltration of external dust into the lubricating oil will make the lubrication conditions of the bearing worse, and even further aggravate the wear of the bearing and reduce the service life of the bearing.
目前通过改进材料的含油轴承能够更好的提供润滑油，但对于高速运转中轴承的温升和润滑油的清洁过滤并没有有效改进；改进的动压润滑轴承可以局部降温，但效果并不突出，且对于润滑油中的杂质无法起到过滤作用，影响轴承的使用寿命。At present, oil-impregnated bearings with improved materials can better provide lubricating oil, but there is no effective improvement in the temperature rise of bearings in high-speed operation and the cleaning and filtration of lubricating oil; improved dynamic pressure lubricated bearings can locally cool down, but the effect is not outstanding , and cannot filter the impurities in the lubricating oil, which affects the service life of the bearing.
通过检索，发现2篇相关专利文献：(1)一种含油——流体动压轴承(CN2898417Y)，其中，动压轴承包括含油轴承套，含油轴承套内设有孔隙，孔隙与含油轴承套的中心孔连通，该含油轴承套的内壁设有两组倾斜的润滑流体导流道，两组润滑流体导流道关于轴承套的中轴面对称。本实用新型中润滑流体的循环过程是一个自冷却过程，这样有利于保持轴的回转精度、提高轴承的使用寿命。(2)一种机械一流体耦合驱动供应润滑油的轴承系统(CN102788038A)，其中，轴承系统包括外圈、滚动体、柔性体、支撑体、储油容积和连通油道。支撑体为一圆环类零件，内部设计有一圆孔，外部设计有一定数量的圆柱形支撑面；柔性体为薄壁圆环类零件，工作时产生微小弹性变形，柔性体的内圆面与支撑体的支撑面组成储油容积；沿柔性体的圆周方向和轴向方向设置有若干用于连接储油容积和外圈的连通油道；滚动体把工作载荷传递到柔性体并使其发生弹性变形；外圈为一旋转类零件，其内圆面与滚动体接触。该发明公布的轴承系统利用零件之间的相互作用，柔性体变形并产生谐波运动，使润滑油的压力发生变化，从而把润滑油经连通油道供应到摩擦表面。这两篇专利中轴承结构没有能够实现润滑油的清洁过滤功能，起到有效延长轴承使用寿命的作用。Through searching, two relevant patent documents were found: (1) an oil-containing hydrodynamic bearing (CN2898417Y), wherein the dynamic pressure bearing comprises an oil-impregnated bearing sleeve, and pores are arranged in the oil-impregnated bearing sleeve, and the gap between the pores and the oil-impregnated bearing sleeve The central hole is connected, and the inner wall of the oil-impregnated bearing sleeve is provided with two groups of inclined lubricating fluid guide channels, and the two sets of lubricating fluid guide channels are symmetrical about the central axis plane of the bearing sleeve. The circulation process of the lubricating fluid in the utility model is a self-cooling process, which is beneficial to maintain the rotation accuracy of the shaft and improve the service life of the bearing. (2) A bearing system (CN102788038A) for supplying lubricating oil driven by mechanical-fluid coupling, wherein the bearing system includes an outer ring, a rolling element, a flexible body, a support body, an oil storage volume, and a communicating oil passage. The support body is a ring-like part, with a round hole inside and a certain number of cylindrical support surfaces outside; the flexible body is a thin-walled ring-like part, which produces a small elastic deformation during operation. The inner circle of the flexible body and the support body The supporting surface of the flexible body constitutes the oil storage volume; along the circumferential and axial directions of the flexible body, there are several communicating oil passages for connecting the oil storage volume and the outer ring; the rolling elements transmit the working load to the flexible body and make it elastically deformed ; The outer ring is a rotating part, and its inner surface is in contact with the rolling body. The bearing system disclosed in the invention uses the interaction between parts, the flexible body deforms and generates harmonic motion, so that the pressure of lubricating oil changes, so that the lubricating oil is supplied to the friction surface through the communicating oil passage. In these two patents, the bearing structure fails to realize the cleaning and filtering function of lubricating oil, which effectively prolongs the service life of the bearing.
