摘要： On a drive shaft (23), formed is an oil discharge passage (71c, 72c, 73c) communicating with an oil supply hole (71a, 72a, 73a), having a flat surface or a recessed surface, and having a width that is less than or equal to a diameter of the oil supply hole (71a, 72a, 73a). A trailing edge of the oil discharge passage (71c, 72c, 73c) is displaced behind a trailing edge of the oil supply hole (71a, 72a, 73a) with respect to the rotation direction of the drive shaft (23). A foreign substance is prevented from being accumulated in the oil supply hole (71a, 72a, 73a) of the drive shaft (23) of the compressor, and therefore, damage to be done to the bearing (29a, 29b, 29c) is reduced.

摘要： A gear pump includes a housing, at least one gear set and a plurality of end plates. The gear set may be positioned between the end plates so that side surfaces of the gears face corresponding side surfaces of the end plates. The side surfaces of the end plates may have a plurality of spiral grooves positioned directly adjacent the side surface of the gears. The plurality of spiral grooves may have a logarithmic shape. Thus arranged, when the gears rotate, fluid in the pump is forced along the lengths of the spiral grooves, creating a local high pressure region that forces fluid between the side surfaces of the gears and the end plates, minimizing or eliminating contact therebetween. In some embodiments the plurality of spiral grooves may be positioned on bearing surfaces of the pump instead of end plates.
摘要翻译：齿轮泵包括壳体，至少一个齿轮组和多个端板。齿轮组可以位于端板之间，使得齿轮的侧表面面对端板的相应侧表面。端板的侧表面可以具有直接邻近齿轮的侧表面定位的多个螺旋槽。多个螺旋槽可以具有对数形状。这样布置，当齿轮旋转时，泵中的流体被迫沿着螺旋槽的长度，产生局部高压区域，迫使齿轮和端板的侧表面之间的流体最小化或消除它们之间的接触。在一些实施例中，多个螺旋槽可以位于泵的轴承表面上，而不是端板。

摘要： The invention relates to a screw spindle pump, having a housing (2) which surrounds a delivery chamber (5), having two spindles (7, 8), specifically a drive spindle (7) and an oppositely rotating running spindle (8), having a housing insert (6) which is arranged in the housing (2) and in which the spindles (7, 8) are accommodated, having at least one bearing element (13', 13'') which is connected to the housing insert (6) and on which bearings (12) of the spindles (7, 8) are arranged, and having at least one housing cover (14', 14'') which closes off a housing opening. It is an object of the invention to provide a screw spindle pump on which maintenance and inspection work can be carried out more easily and inexpensively. Said object is achieved by means of the invention in that the bearing element (13', 13'') forms a unit (15) with the housing insert (6) and the spindles (7, 8) accommodated therein, which unit can be removed from the housing (2) through the housing opening after the housing cover (14', 14'') has been removed.

The first and second gears have gear teeth and trunnions (26,34) on opposite sides thereof, and are disposed in the pump housing (28). The gear teeth of the first and second gear are meshed in a mesh region (52). An inlet cavity (58) is defined adjacent to the first and second gears, on one side of the mesh region (52). A pump outlet (60) is defined on an opposite side of the mesh region (52) from the inlet cavity (58). A bearing (36,38) is configured to support at least one trunnion (26,34) of the first gear and/or the second gear. A bearing interface (40) is defined between the bearing and the at least one trunnion. A flow path (68) is defined between the bearing interface (40) and the inlet cavity (58).
