轴颈式配油器在液压马达上应用得非常广泛。这类配油器可分为两种:一种是油液从中心部位向外配油,称为内配油轴颈式配油器;另一种是油液从外向中心部位配油,称为外配油轴颈式配油器。内配油轴颈式配油器,配油付尺寸较小,配油轴可安置于液压马达的中心部位,马达的轴向长度较小。如果是双速马达,变速阀也可安装于配油轴中部,结构比较紧凑。但它的一个很大缺点是进出油管往往联接在浮动的配油轴上,这样,油管就需用软管与马达联接,如用钢管,将使配油轴的浮动性能大大变坏。而 The journal type oil distributor is widely used on the hydraulic motor. This type of oil distributor can be divided into two kinds: one is the oil from the central part of the outward distribution of oil, known as the inner distribution of oil with a neck distributor; the other is the oil from the outside to the central part of the oil, said In addition to the distribution of oil pipe fittings. The oil distribution within the distributor, with oil to pay smaller size, the oil axis can be placed in the center of the hydraulic motor, the motor axial length smaller. If it is a two-speed motor, variable speed valve can also be installed in the central oil distribution, the structure is more compact. However, one of its great drawbacks is that the oil in and out of the oil pipe are often connected to a floating oil distribution shaft. In this case, the oil pipe needs to be connected with a motor by using a hose, for example, a steel pipe, which greatly deteriorates the floating performance of the oil distribution shaft. and
