Description
Technical field
The utility model relates to a kind of motorcycle engine water pump, and Centrifugal water pump is used in particularly a kind of motorcycle engine cooling of adopting rolling bearing, sliding bearing together support water pump spindle, belongs to mechanical field.
Background technique
The water pump structure that present motorcycle engine adopts usually is: drive water pump vane by a water pump spindle and quicken the cooling water circulation, a water pump vane and a cover mechanical seal device cooperate and prevent the cooling water crankcase that bleeds, adorn an oil sealing in the mechanical seal device lower end and prevent that the oil in the crankcase from entering water pump, and in order to keep water pump spindle stable, shown in A and B among Fig. 1, usually two rolling bearings of employing support and locate, this structure is owing to be two bearings, the space that requires is bigger, when arranging with cooperating of complete machine to bulk require relatively largely, and comparatively trouble is installed also.
Along with the manufacturing development of motorcycle, the trend of complete machine miniaturization is clear and definite day by day, therefore just bring complete machine just to be difficult to adopt the structure of this two roller bearings and location for the smaller motor in this positioned opposite space for cooperating the space of arranging to diminish.
The model utility content
The purpose of this utility model is to provide a kind of structure simpler motorcycle engine pumping plant at the deficiency of existing two roller bearings water pump spindle technology, it supports water pump spindle by sliding bearing and the rolling bearing that is provided with on crankcase cover, simplified the engine water pump structure, make shared spatial arrangement position reduce, reduce by a rolling bearing, reduced cost.
The utility model is achieved by the following technical solution:
A kind of motorcycle engine water pump which comprises at least water pump vane, and water pump spindle, bearing, crankcase cover, water pump cover, described water pump spindle pass a through hole that is opened on the crankcase cover; In a side of described through hole, water pump spindle is fixedlyed connected with water pump vane, and is sealed in the water pump cover; At the opposite side of described through hole, the other end of described water pump spindle is set in the bearing, and this bearing fixing is on crankcase; Described water pump cover be located on the crankcase cover and with this crankcase cover by bolt and forms the cavity that holds water pump vane; Described cavity has the mouth of pipe that the outflow of supplying water is gone into.In this design proposal, cancelled a rolling bearing in traditional water pump, and replaced with a through hole that is opened on the crankcase cover, the volume of water pump is dwindled.
For guaranteeing that motion good between above-mentioned through hole and the water pump spindle cooperates, described through hole to be offered be circle, the diameter of its diameter and described water pump spindle is complementary, and formation is slidingly matched.Simultaneously, offer the depression oilhole of oil groove or dispersion at the inwall of described long through-hole.By such setting, can in oil groove or oilhole, insert lubricant oil, thereby reduce the friction between water pump spindle and through hole, constitute sliding bearing.
In the above-mentioned scheme that lubricant oil is set, can also adopt in the described water pump spindle and the outside at the described through hole place of matching and offer endless oil groove or axial oil groove or half oilhole, and lubricant oil be inserted in the oil groove or oilhole of water pump spindle; No matter oil groove is any shape, as long as can trapped fuel, can play lubricated effect.
For other parts that make above-mentioned sliding bearing and water pump are isolated, prevent that lubricant oil from leaking outside or other liquid, impurity enter through hole and influence the proper functioning of this sliding bearing, be provided with oil sealing at described through hole by water pump vane one side, this oil-sealing sleeve is located at the water pump spindle outside, and the embedding crankcase cover is positioned at the oil seal groove that the through hole is offered.
The utility model is compared with existing product, and its advantage is:
1, simplifies the structure: technological scheme provided by the utility model, cancelled in traditional motorcycle water pump needed two each rolling bearings, by directly offering through hole on the crankcase cover and a rolling bearing is set below through hole is supporting water pump spindle, not only lack and used one pair of bearing than prior art, simplified operation, also make the required assembly space of complete machine littler, and the performance of parts and whole water pump is had no effect.
2, save cost: the utility model only adopts one pair of bearing, simultaneously, in production and processing, simplifies and reduced operation, uses two pairs of bearings to reduce cost than the prior art scheme.
Description of drawings
Fig. 1 is the motorcycle engine water pump structure schematic representation of prior art;
Fig. 2 is a specific embodiment structural representation provided by the utility model;
Fig. 3 cooperates schematic representation between through hole in embodiment illustrated in fig. 2 and water pump spindle.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 2, water pump provided by the utility model comprises at least: water pump cover 1, water pump vane 2, water pump spindle 3, oil sealing 4, crankcase cover 5, bearing 6.
Described water pump is arranged on the body of crankcase cover 5, forms the space 7 that can hold water pump vane 2 by the water pump cover 1 that be located on the crankcase cover 5, and this space 7 is provided with the mouth of pipe that supplies water and flow to out.
In above-mentioned water pump, water pump spindle 3 passes a through hole 51 that is opened on crankcase cover 5 bodies and enters space 7, and fixedlys connected with water pump vane 2 in space 7, and the other end of this water pump spindle 3 is inserted in the bearing 6, and with these bearing 6 stationary fits.Described bearing 6 is fixedly installed on the crankcase cover 5.
Water pump spindle 3 carries out stable rotation under the together support of through hole 51, bearing 6, and drives water pump vane 2 rotations, reaches the purpose that cooling water is circulated.
Have comparatively good being slidingly matched for making between water pump spindle 3 and the through hole 51, reduce friction, through hole 51 and water pump spindle 3 are mated setting, make in its cooperation place to have glade plane space 53 (as shown in Figure 3) between through hole 51 and the water pump spindle 3.
In addition, for further reducing the friction between water pump spindle 3 and the through hole 51, on the inwall of through hole 51, offer all oil grooves 52 of ring.In the water pump assembling, in all oil grooves 52 of described ring, add lubricant oil, thereby make water pump spindle 3 and the sliding bearing that through hole 51 constitutes have good runnability.
In the above-mentioned lubricant oil adding scheme, also can adopt the scheme of offering oil groove in the outside of water pump spindle 3, the effect of offering all oil grooves 52 of ring in its effect and the through hole 51 is identical.
For making other parts isolation of the above-mentioned sliding bearing that constitutes by water pump spindle 3 and through hole 51 and water pump, prevent that lubricant oil from leaking outside or other liquid, impurity enter through hole 51 and influence the proper functioning of this sliding bearing, be provided with oil sealing 4 at described through hole 51 by water pump vane 2 one sides, this oil sealing 4 is set in water pump spindle 3 outsides, and embedding crankcase cover 5 is positioned at the oil seal groove 54 that through hole 51 places offer.
It should be noted last that: above embodiment is the unrestricted technological scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, and not breaking away from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
