机械零件中,滑动轴承内孔表面需开出直线或螺旋线等各种形式的油槽,使润滑油充分分布到轴承工作表面,以减少轴承和轴颈之间的摩擦,提高机械效率和延长使用寿命,在液压元件中,某些轴套(相当于滑动轴承)中的油槽,既具有润滑作用,还对液压具有平衡作用。 直线油槽的加工较为容易,螺旋线特别是大螺旋 Mechanical parts, the inner surface of plain bearings need to open a straight line or helix and other forms of oil tank, the lubricant fully distributed to the bearing surface, in order to reduce the friction between the bearing and journal, improve mechanical efficiency and extend the use of Life expectancy, in the hydraulic components, some of the sleeve (equivalent to the sliding bearing) in the groove, both with lubrication, but also have a balance of hydraulic. Linear tank processing easier, especially the spiral large helix
