外啮合齿轮泵(以下简称齿轮泵)广泛应用在各种液压机械中。但是由于高压齿轮泵的轴承承受很大的径向力,并且轴承受齿轮泵结构的限制,只能用径向尺寸比较小的轴承,如滚针轴承和滑动轴承。而滚针轴承和一般的滑动轴承往往承载能力都较低,因此轴承的磨损成为影响齿轮泵寿命和压力提高的主要原因。以往140 kgf/cm~2以上压力的国产齿轮泵,寿命一般只有1000小时。为解决高压齿轮泵的寿命问题,在辽源科技研究所的协助下,我厂于1978年正式将GS-1材料轴承应用在CBF-E型齿轮泵中。六年来,共生产销售二万余台泵,经台架寿
External gear pump (hereinafter referred to gear pump) is widely used in a variety of hydraulic machinery. However, because high-pressure gear pump bearings bear a great radial force, and the bearing structure by the gear pump restrictions, only the radial size of smaller bearings, such as needle bearings and plain bearings. Needle bearings and plain bearings are often carrying capacity is low, so the bearing wear and tear become the main reason affecting the life and pressure of the gear pump. In the past 140 kgf / cm ~ 2 pressure above the domestic gear pump, life expectancy is generally only 1000 hours. In order to solve the problem of life of high pressure gear pump, with the help of Liaoyuan Institute of Science and Technology, our factory formally applied GS-1 material bearing to CBF-E gear pump in 1978. Over the past six years, a total of more than 20,000 sets of production and sales pump, the bench life
