推荐使用场合:
这种结构综合了铜合金和润滑材料的各自特点,可以在难以形成油膜润滑和因条件限制而不能添加润滑剂的场合使用。基体含有的润滑材料一般贯通轴承内外径,设备在运转使用过程中,通过摩擦使润滑材料与轴相互摩擦,润滑材料和润滑油不断渗出,在轴承内壁和轴之间形成油膜润滑的优异条件,既保护轴不磨损,又使固体润滑特性持续永恒。可以用在低速重载不便维护,无给油的工况,并且在零下温度和零上

Bronze bearing with solid
modern-day bearing materials. Zeromaintenance is often expected under severe to extreme conditions as well asunder maximum loads.
The constant pressure on costs also calls forincreasing uptime of machinery and equipment and uncompromising standards ofoperational reliability. materials are suitable for applications involvingsustained high static and dynamic loads,relatively low sliding speeds androtary, angular, axial or linear motion. They are also suitable forapplications where conventional lubrication is not possible or permissible, orwhere other properties are required such as durability and resistance tooperational and environmental or special conditions (e.g. impact load, abrasivestress, etc).
In conventionally lubricated bronze materialsa„separating lubricating film“ canonly be formed if themovement conditions and sliding speeds are suitable.Withself-lubricating bearing, the lubrication is provided by thesliding materialitself. The solid lubricant is released from the bearing material by microabrasion as soon as thesliding movement begins. This gives the slidingpartnerssmooth surfaces with a firmly adhesive solid lubricantfi lm. The solidlubricant remains within the contact zoneeven under heavy loads, resulting in ahigh degree ofseparation between the sliding surfaces and a sustainedlow coefficient of friction coupled with minimal wear.
现代轴承材料设计要求产品应用在零维护及预计经常在恶劣极端条件以及最大负荷下。成本压力不断加大的同时还要求机械设备增加正常运行时间,严格标准的运行可靠性,此型号产品的润滑材料全部集中在轴承的内径表面包裹旋转轴,既能最大限度的保留轴承的承载力又最大的满足了工况的润滑要求,材料适合应用涉及持续的高静态和动态负载。
能相对降低的滑动速度摩擦力,可以用于旋转,角度,轴向或直线运动。润滑是由提供滑动材料本身提供的,只要运转开始固体润滑剂就会通过微磨损的轴承材料来释放,润滑剂保持接触的区域内的甚至在重负载下,高性能的滑动表面和一个持续之间的分离低摩擦系数可以保证轴承的磨损量在非常小的范围内。
