Abstract
The utility model discloses a water pump assembly of an engine of a motorcycle. The water pump assembly comprises a water pump shaft (1) and an impeller (2); a water pump gear (3) is arranged at the end, which is far away from the impeller (2), of the water pump shaft (1); the water pump shaft (1) is supported by a mounting hole positioned on a right crankcase cover (6); the water pump gear (3) is a plastic gear and is arranged on the water pump shaft (1) by means of press fitting; an end surface bearing (5) is arranged at an orifice, which faces a gear end, of the right crankcase cover (6); a water pump shaft pressure plate (4) is arranged on one side, which is positioned on the water pump gear (3), of the end surface bearing (5), and a steel wire ring washer (7) is arranged on the other side of the end surface bearing (5); the water pump shaft (1) is provided with a water seal assembly (8) close to the water pump impeller (2); and the water pump shaft (1) is provided with an oil seal (9) close to the water seal assembly (8). The water pump assembly has the advantages of compact structure, convenience in installation and low work noise.
Description
Technical field
The utility model relates to a kind of water pump structure, particularly relates to a kind of water pump complement for motorcycle engine.
Background technique
In prior art, water pump complement comprises water pump spindle and water pump vane, rotates by the rotation impeller of water pump spindle, thereby realizes pumping function.The rotation of water pump spindle realizes by the water pump gear that is installed on it.But because gear is connected by conventional key with axle, so water pump gear installation separately, this has increased the complexity of follow-up assembling, installs particularly troublesome when particularly changing assembly; On the other hand, have the fit up gap between this constitution water pump shaft and gear, this will cause producing in the pump working process larger noise.
Therefore those skilled in the art are devoted to develop a kind of Water pump for engine of motor cycle assembly easy to use, that noise is low that assembles.
The model utility content
Because the defects of prior art, technical problem to be solved in the utility model is to provide a kind of Water pump for engine of motor cycle assembly more convenient, that noise is lower that assembles.
For achieving the above object, the utility model provides a kind of Water pump for engine of motor cycle assembly, comprises water pump spindle and impeller; The far-end of the relatively described impeller of described water pump spindle is provided with water pump gear; Described water pump spindle is by being positioned at the mounting hole supporting of right crankcase cover; Described water pump gear is plastic gear, is fitted on described water pump spindle; Described right crankcase cover is provided with the end face bearing towards place, gear end aperture; Described end face bearing is positioned at described water pump gear one side and is provided with the water pump spindle pressing plate, and opposite side is provided with the steel wire ring washer; Described water pump spindle is provided with water-sealed component near described water pump vane place; Described water pump spindle is being provided with oil sealing near described water-sealed component place.
The fit diameter of described water pump spindle and described water pump gear is 16mm.
The beneficial effects of the utility model are: the utility model utilizes right crankcase cover as water pump body, makes more compact structure; Owing to adopting nylon gear and Integral press-fitting structure, make installation more convenient, and the fit up gap of having eliminated gear and axle, thereby make operating noise less.The utility model compact structure, easy for installation, operating noise is little.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of Water pump for engine of motor cycle assembly comprises water pump spindle 1 and impeller 2, and the far-end of water pump spindle 1 relative impeller 2 is provided with water pump gear 3.
Water pump gear 3 is plastic gear, is fitted on water pump spindle 1.Water pump spindle 1 is 16mm with the fit diameter of water pump gear 3.
Water pump spindle 1 is by being positioned at the mounting hole supporting of right crankcase cover 6, and right crankcase cover 6 is provided with end face bearing 5 towards place, gear end aperture.End face bearing 5 is positioned at water pump gear 3 one sides and is provided with water pump spindle pressing plate 4, and opposite side is provided with steel wire ring washer 7.Water pump spindle 1 is provided with water-sealed component 8 near water pump vane 2 places, is being provided with oil sealing 9 near water-sealed component 8 places.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
