Abstract
The utility model relates to a cycloid fuel pump used for lubrication of machine tools and hydraulic motor pumps, belonging to the technical field of hydraulic machinery. The cycloid fuel pump is composed of a pump axle, internal and external rotors, oil seals, and complexion bearings. The utility model has the essential features that the structure of median plates with three straps, front covers and rear covers is adopted, oil plug grooves and oil through holes are arranged on the median plates, and axle center holes which are communicated with oil inlet holes through oil return holes on the rear covers are arranged in the pump axle. The utility model has the advantages of good sealing performance of the pumps, strong automatic suction capacity. The standard of CB-B series gear pump is adopted in the dimension of installation and connection, inlet and outlet oil holes, and a plurality of model numbers for the cycloid fuel pump which are convenient to substitute for the CB-B gear pumps originally used in the machine tools. Thus, the utility model has good compatibility.
Description
The utility model relates to the lubricating pump that lathe is used, particularly gerotor lube pumps, belongs to the oil hydraulic pump technical field.
The Swing line oil pump that is used for machine tool lubrication at present, mainly by the pump housing, pump cover, pump shaft, the axle sleeve that is provided with on the pump shaft, composite bearing, internal rotor, the eccentric bushing that is provided with in the pump housing inner chamber, external rotor, and locate formations such as Xiao, spring seat, seal ring, this gerotor lube pumps, suction capacity is poor, flow is little, can only be used for lubricant pump, can not use as hydro-power pump, sealing is poor, and water clock oil is serious.Both can make lubricating pump, also can be used as the CB-B gear pump of hydraulic power,, adopt two axles and two gears because this pump structure complexity, volume are big, the profile oval in shape, difficulty of processing is big, and material consumption is many, the manufacture cost height, usability is poor, and the life-span is short, has been listed in obsolete product.
The purpose of this utility model provides the Swing line oil pump that can be used for lubricated and hydraulic power supply that a kind of volume is little, suction capacity is strong, flow is big.
The purpose of this utility model is achieved in that Swing line oil pump comprises pump shaft 2, outside framework oil seal 3, composite bearing 12, the internal rotor 15 that is provided with on external rotor 14 and the pump shaft 2, it is characterized in that Swing line oil pump is provided with middle sheet 6, protecgulum 5, bonnet 8, external rotor 14 is located in the eccentric opening of middle sheet 6, the edge that internal rotor 15 contacts with pump shaft 2 is provided with axle ring washer 16, establish composite bearing 12 on the contact-segment of pump shaft 2 and protecgulum 5 bonnets 8, middle sheet 6 is provided with stifled oil groove 1 and oil through 19, bonnet 8 is provided with spill port 7, stifled oil groove 1 communicates with oil through 19, establish axle center hole 11 in the middle of the pump shaft 2, oil through 19 and axle center hole 11 all communicate with spill port 7.Middle sheet 6, protecgulum 5, bonnet 8 adopt location Xiao 13 location and bolt to install and fix, and protecgulum 5 contacts end face and adopts outside framework oil seal 3 to seal with pump shaft 2.In order to improve the suction capacity of pump, oil outlet 17, oil inlet hole 18 adopt axial bore.Change the use Swing line oil pump for the ease of the lathe of the original CB-B of use gear pump, guarantee the interchangeability of complete series, four on the protecgulum 5 screws are installed and are located on the same circumference, the angle on left and right both sides is 90 °, and last angle is 100 °, and following angle is 80 °.The installation dimension of Swing line oil pump, Conncetion cimension, turnover oilhole and serial model No. all adopt CB-B series gear pump standard.
The utility model is rational in infrastructure simple, sheet in the employing, protecgulum, this three pieces type structure of bonnet, manufacturing is easy, usability is good, middle sheet and protecgulum, radially oil impregnate between the bonnet can be by stifled oil groove, oil through, spill port flows to oil inlet hole, pump shaft and protecgulum, axial oil impregnate between the bonnet can pass through axle center hole, spill port flows into oil inlet hole, solved the common fault of general oil pump water clock oil, reached good seal, suction capacity is strong, noise is little, flow is big, long service life, can reduce the lathe mating power, be the ideal pump of machine tool lubrication and hydraulic power, and the excellent popularization using value is arranged.
