齿轮油泵被广泛地应用在农业机械的液压系统中,齿轮油泵轴套的润滑直接关系到泵的使用寿命,这是因为齿轮油泵在工作中,轴套要承受很大的径向载荷,极易磨损,因此要保持良好的润滑条件,润滑油同时还兼有散热、清除磨屑等作用。 一般轴套的润滑方式有以下两种: 1.高压节流润滑 利用高压油经节流降压后润滑轴套,通常在轴套端面上开有八字形节流槽,轴套内孔开有直槽。 2.低压油润滑 利用低压油润滑轴套,常在轴套端面的吸油腔一侧开润滑油槽,轴套内 Gear pump is widely used in agricultural machinery hydraulic system, gear pump sleeve lubrication is directly related to the life of the pump, it is because the gear pump in the work, the sleeve to bear a great radial load, easily Wear and tear, so to maintain good lubrication conditions, lubricants also have both heat, remove debris and other effects. Lubrication of the general sleeve in the following two ways: 1. High-pressure throttling lubrication using high-pressure oil after the throttle decompression lubrication sleeve, usually open in the sleeve end face eight-shaped throttle, open the bore hole Straight groove. 2. Low-pressure oil lubrication The use of low-pressure oil lubrication bushing, often in the sleeve side of the suction side of the oil chamber open lubrication groove, shaft sleeve
