我室编制的《φ40～200液体静压轴承系列设计参数》目前已广泛地应用于各类机床的设计和设备的改造上。但在应用过程中,一些单位提出了以下两个问题:(1)油腔有效承载面积的近似计算与较精确计算的误差有多大?(2)轴承的轴向封油边长l_1与周向封油边b_1均按l_1=b_1=0.1D(D为轴承直径)进行计算设计的,但有些国外资料介绍轴承在低速工作时,则按l_1=b_1=D/4～D/6进行设计,对于这种宽封油边的轴承设
My room preparation “φ40 ~ 200 hydrostatic bearing series design parameters” has been widely used in various types of machine tool design and equipment transformation. However, during the application process, some units put forward the following two questions: (1) The approximate calculation of the effective bearing area of the oil chamber and the error of the more accurate calculation? (2) The axial oil seal length l_1 of the bearing and the circumferential The oil seal b_1 is designed and calculated according to l_1 = b_1 = 0.1D (D is the bearing diameter). However, some foreign information describes that the bearing should be designed according to l_1 = b_1 = D / 4 ~ D / 6 when working at low speed, For this wide seal oil bearing set
