【摘要】 本文对一种新型径向柱塞泵的定子和连杆滑靴高速滑动摩擦副进行了可靠性和寿命的试验研究。讨论了摩擦副选材的四种方案,并进行了强化试验,结果表明,定子材料为GCr15,连杆滑靴为40Cr基体上喷涂MoS2的摩擦副具有较高的可靠性和寿命。更多还原

【Abstract】 A new radial piston pump developed.And the structure study,movement analysis,edurance analysis and reliability study on materials of the high-speed slip couple were carried out.Based on the comparison of the performaces of different materials and reliability test,the slippers materials of 40Cr surface spray paints MoS2 have better reliability and long life.The reliability of the couple can meat the requirement of the pump’s design longevity.更多还原
