Description
Technical field
The utility model relates to the matching used oil pump product of a kind of motorcycle engine manufacturing technology, especially refers to the filter apparatus configuration of oil pump filler opening.
Background technique
Machine oil pump for motor is to guarantee normal cooling of motorcycle gasoline engine and lubricated important accessory, and its work under bad environment, rotating speed are higher; At present common oil pump product comprises the pump housing and the pump cover of outer shape triangular in shape, is provided with a pair of inside and outside cycloid wheel in the pump housing, and it utilizes rotating shaft to drive the rotation of hypocycloid wheel, realizes the engagement between the inside and outside cycloid wheel and makes machine oil generation working pressure.In real work, the motorcycle of existing weaponry and equipment four stroke engine is that oil mass is the bigger the better to the requirement of oil pump, is subjected to good lubricated and cooling so that guarantee engine gear.At present, existing motorcycle engine housing is many to be made by the aluminum alloy material die-casting process, can scraping take place with the engine shell intracoelomic cavity unavoidably and produce foreign matters such as aluminium bits when gearbox gear runs up; And oil pump is high-precision product, and in a single day the foreign matters such as aluminium bits of trace enter the pump housing and just might cause the oil pump clamping stagnation, and badly damaged inside and outside cycloid wheel reduces the service behaviour of oil pump greatly, and shorten working life.
The model utility content
The technical problems to be solved in the utility model is to overcome defective and the deficiency that foreign matters such as aluminium bits that prior art products exists enter oil pump pump housing inner chamber, badly damaged inside and outside cycloid wheel easily, provide a kind of machine oil pump for motor product to society at filler opening tool filtrating equipment, enter the degree of purity of pump housing inner chamber machine oil with raising, guarantee inside and outside cycloid wheel proper functioning, improve reliability of products and working life.
The technological scheme that its technical problem that solves the utility model adopts is: the machine oil pump for motor of band filter cap, the pump housing, the pump cover that comprise connection fastened to each other, be provided with hypocycloid wheel, epicyclodial wheel and rotating shaft in the described pump housing, the described roller end that is positioned at the described pump housing is provided with radial pins and is connected with described hypocycloid wheel; The end that described rotating shaft stretches out in the described pump housing is used to connect driving gear; The filler opening of the described pump housing is the stepped shape cylindrical cavity, and described filler opening inner chamber is plugged with the L type and takes over; The below port of described adapter is provided with filter cap, and the end cap of described adapter and described filter cap is fixedly connected.
Described adapter is embraced piece by arc and is fixed through screw and described pump housing lower edge.
Described adapter is provided with annular protrusions near the position of described filler opening inner chamber step, is provided with seal ring between described annular protrusions and the described filler opening inner chamber step.
The machine oil pump for motor of the utility model band filter cap is plugged with the L type at the filler opening inner chamber of the described pump housing and takes over, and the below port of described adapter is provided with filter cap; When the foreign matters such as aluminium bits of gearbox gear and engine shell intracoelomic cavity generation scraping generation are back to the filler opening of machine oil pump for motor with machine oil, foreign matters such as aluminium bits have been subjected to stopping of filter cap and can't have entered, thereby guaranteed to enter the degree of purity of oil pump pump housing inner chamber machine oil, guarantee the proper functioning of inside and outside cycloid wheel, improved reliability of products and working life greatly.Compare than prior art products, have characteristics novel, reasonable in design, compact structure, be widely used in the supporting application of motorcycle main frame factory.
Description of drawings
Fig. 1 is the utility model product cross-sectional view.
Fig. 2 is Fig. 1 left view.
Embodiment
As depicted in figs. 1 and 2, the machine oil pump for motor of the utility model band filter cap comprises the triangle pump housing 1 and the pump cover 2 that are fixedly connected by many pieces of screws 8, is provided with locating stud 6 location between the described pump housing 1 and the pump cover 2; Be provided with hypocycloid wheel 4, epicyclodial wheel 3 and rotating shaft 5 in the described pump housing 1, described rotating shaft 5 ends that are positioned at the described pump housing 1 are provided with radial pins 7 and are connected with described hypocycloid wheel 4; The end that described rotating shaft 5 stretches out in the described pump housing 1 is used to connect driving gear; The assembly method of the described pump housing 1, pump cover 2, hypocycloid wheel 4, epicyclodial wheel 3 and rotating shaft 5 as State Intellectual Property Office on February 25th, 2004 notice of authorization, the patent No. is called the utility model patent technology of " the lubricated oil pump of using of a kind of motorcycle " for the ZL03233176.2 name, belong to existing known technology category, so repeated description no longer.
As depicted in figs. 1 and 2, filler opening 17 of the present utility model is located at the described pump housing 1 lower edge 15, and described filler opening 17 is the stepped shape cylindrical cavity; Described filler opening 17 inner chambers are plugged with the L type and take over 13, and described adapter 13 is embraced piece 11 by arc and fixed through screw 9 and the described pump housing 1 lower edge 15; Described adapter 13 is provided with annular protrusions 16 near the position of described filler opening 17 inner chamber steps, is provided with seal ring 12 between described annular protrusions 16 and the described filler opening 17 inner chamber steps.The below port of described adapter 13 is provided with filter cap 10, and described adapter 13 is fixedly connected with the end cap 14 of described filter cap 10.
Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.When rotating shaft 5 was run up by the driving gear driving, the big oil mass machine oil of formation produced good lubricated and cooling to engine gear.And gearbox gear and engine shell intracoelomic cavity take place that scraping produces foreign matter such as aluminium bits and when being back to the filler opening 17 of oil pump with machine oil, foreign matters such as aluminium bits have been subjected to stopping of filter cap 10 and can't have entered, thereby guaranteed to enter the degree of purity of oil pump pump housing inner chamber machine oil, guarantee the proper functioning of inside and outside cycloid wheel, improved reliability of products and working life.
