Description
One, technical field
The utility model relates to a kind of water pump, especially the motorcycle engine water pump.
Two, background technique
At present, the motorcycle engine water pump mainly contains two kinds of structural types, and a kind of is split-type structural, and its structure characteristic is that component such as water pump spindle, oil sealing, bearing and water seal directly are assemblied in the endoporus of crankcase body float chamber lid, water channel is arranged on engine crankshaft casing float chamber and covers, this structure takes up room little, but as long as individual parts such as oil sealing, bearing and water seal are damaged, whole parts must be pulled down, and then change, refitting, not only time-consuming but also require great effort, extremely inconvenient; Another kind is a monolithic construction, its structural feature is that component such as water pump spindle, oil sealing, bearing and water seal are installed in the water pump body endoporus, water channel is arranged on the water pump body, water pump body is installed in the endoporus of crankcase body float chamber lid, the advantage of the water pump of this structure is if damage parts is arranged, the water pump body integral body that only needs component such as oil sealing, bearing and water seal will be installed is pulled down, change the water pump body that another one has assembled component such as water pump spindle, oil sealing, bearing and water seal then, be that integrated type is replaced, time saving and energy saving, installation and maintenance are convenient.Because the inlet channel of this water pump is arranged on the water pump body, therefore whole water pump occupation space is big.
Three, model utility content
The purpose of this utility model provides and a kind ofly takes up room for a short time, and assembling and maintenance be motorcycle engine water pump very easily again.
The technical solution of the utility model is: a kind of motorcycle engine water pump, oil sealing, bearing and water seal are installed in respectively in the axial circular hole of each section of water pump body, bearing, water seal lays respectively at the both sides of oil sealing, seal ring is arranged in the annular groove of water pump body cylindrical, water pump spindle passes bearing, oil sealing and water seal, impeller is fixedly connected on the water pump spindle axle head, the water pump body Spielpassung covers at right crankcase, the hole that water pump body radially is provided with communicates with the hole that right crankcase covers setting, it is characterized in that: the right crankcase cover that water pump body is installed is provided with inlet channel, and inlet channel communicates with water outlet on the water pump cover.
The utility model middle (center) bearing, oil sealing and water seal are separately positioned on each section endoporus of water pump body, and water pump body, bearing, oil sealing and water seal constitute an one-piece element and be installed in the endoporus of right crankcase cover, and assembling and dismounting maintenance are convenient; Because inlet channel is arranged in the right crankcase cover, and need not be arranged in the water pump body, dwindle the volume of water pump body, thus whole water pump take up room little, so it has had the advantage of original split type and integrated type motorcycle engine water pump concurrently.
The utility model has the advantages that: assembling and easy to maintenance occupies little space.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, embodiment
As Fig. 1: the utility model is mainly by right crankcase cover 1, water pump body 3, back-up ring 4, water pump gear 5, water pump spindle 6, bearing 7, round section joint ring 8, oil sealing 9, round section joint ring 10, sealing gasket 11, water seal 12, impeller 13 and water pump cover 14 are formed, wherein oil sealing 9, bearing 7 and water seal 12 are installed in respectively in the axial circular hole of water pump body 3 each sections, bearing 7, water seal 12 lays respectively at the both sides of oil sealing 9, seal ring 8 is arranged in the annular groove of water pump body 3 cylindricals, water pump spindle 6 passes bearing 7, oil sealing 9 and water seal 12, impeller 13 is fixedly connected on water pump spindle 6 axle heads, water pump body 3 Spielpassung are on right crankcase cover 1, the hole 17 that is provided with on the hole 16 that water pump body 3 radially is provided with and the right crankcase cover 1 communicates, it is characterized in that: the right crankcase cover 1 that water pump body 3 is installed is provided with inlet channel 2, and inlet channel 2 communicates with water outlet 15 on the water pump cover 14.
As can be seen from Figure 1: the outside of water seal 12 communicates with inlet channel 2 and water outlet 15 with the cavity that water pump body 3 forms.Be provided with round section joint ring 10 between right crankcase cover 1 and the step surface that water pump body 3 matches.
During engine operation, by serial transmission water pump gear 5 is rotated, then water pump spindle 6 impeller 13 rotations are sent to water outlet 15 on the water pump cover 14 to the water in the inlet channel 2, reach the purpose of pump water.
Be Spielpassung between the endoporus of water pump body 3 and right crankcase cover 1 in the utility model, be interference fit between the endoporus of bearing 7, oil sealing 9 and water seal 12 and water pump body 3, and the oil in the employing round section joint ring 8 canned motor crankcases, round section joint ring 10 is sealed into the water in water channel 2 and the water outlet 15, if damage parts is arranged, water pump body 3 integral body that only need component such as oil sealing 9, bearing 7 and water seal 12 will be installed are pulled down, change the water pump body 3 that another one has been equipped with component such as oil sealing 9, bearing 7 and water seal 12 then, assembling and easy to maintenance; No inlet channel 2 in the water pump body 3, and inlet channel 2 is arranged on the right crankcase cover 1, having reduced the spatial position that water pump is installed, he is with the advantage of original split type and integrated type motorcycle engine water pump.
