In order to deal with mechanical equipment in high temperature, low speed, large overload, dust, water shower and have rushed composite bearing oscillation of smooth, using composite sliding bearing.
1, bearing the structure of the composite sliding bearing is developed on the surface of the bearing substrate metal conflict put orderly intrusive proper cavity, and embedded mos2 and graphite etc made from composite since GuangHuaHua inlaid on the metal sleeve piece, after bearing, made of solid smooth agent friction area of 25-65%.Solid from the smooth piece can normal operation under the high temperature of 280 ℃.But because of its low mechanical strength, bearing ability is weak, prone to deformation, it is embedded in the metal hole groove sliding bearing can contain this kind of defect, to form the metal part load effect, since smooth piece of smooth effect.Smooth mechanism of this composite sliding bearing is in the process of shaft and the sliding conflict, part of the molecules from the smooth data transferred to the axis of the metal surface, fill tiny is not flat, and formed a solid light synovial layer is relatively safe, to form a solid light synovial grinding, avoid axis and the set of adhesive wear.Contact the rationality of the combination of copper alloy and non-metallic antifriction materials their complementary advantages, particularly suited to oil-free, high temperature, high load, low speed, anti-fouling, corrosion resistant, strong radiation in the environment movement, and in the water or other solution to moisturize and smooth foundation is unable to add grease used under special working conditions.
2, from the smooth piece of area than from the smooth piece of surface area much related to the intensity of the work speed, pressure, speed is low;Pressure strength, metal thrown some of area.Grasp such as ingot tractor road wheel bearing from the smooth piece of 25% of the area of mercy, smooth to the pull mechanism shaft bearing, bearing strength is not big, the mercy from the smooth piece of area of 65%.
3, transform the data set of skills request bushing should choose copper alloy manufacture, bushing should have high hardness, usually must be heat treatment, the hardness is not lower than HRC45.
4, from the smooth piece how much shape, and set the request.Since the shape of the smooth piece of cylindrical and rectangular two kinds, the smooth according to the area of intrusive can use cylindrical, vice can use rectangle.No matter what shape it is necessary to set strong, prevent running in the fall.
5, bushing and the axial gap with the value from the smooth piece of the linear expansion coefficient of about 10 times of steel.In order to adapt to bearing temperature change, the shaft and bushing by original metal pieces of four grades with the gap (D4 / DC4) 0.032 ~ 0.15 MM, 0.45 ~ 0.5 MM.Since the smooth blocks at the side of the conflict, deputy outstanding bushing metal 0.2 ~ 0.4 MM.It will work in bearing initial grinding close period and smooth, cut power drag power cost.
