Abstract
The utility model relates to a water-cooled motorcycle engine water pump, which comprises a water pump shaft (4), a water pump body (3), a water pump gear (8) and a blade wheel (1), wherein the blade wheel (1) is arranged on one end of the water pump shaft (4); the water pump gear is arranged on the other end of the water pump shaft (4); the water pump body (3) is arranged on the pump shaft (4) through a bearing and is positioned between the blade wheel (1) and the water pump gear (8); the water pump body (3) is provided with a water seal (2) and a oil seal (5) inside; the water pump shaft (4) is broken into the front section and back section close to the water pump gear (8), and suitable connection socket (4a) and connection lug boss (4b) are arranged in the binding position of the front and back section. The utility model reduces the working procedure of assembling a water pump on the engine, so as to make the assembly of the pump become easy and simple, and help to guarantee the assembly quality of the pump.
Description
Technical field
The utility model relates to water pump, specifically, relates to a kind of water-cooling motorcycle engine water pump.
Background technique
In the existing cooling motorcycle engine water, particularly be used for the high-power cooling motorcycle engine water of beach buggy, the external diameter of clutch housing is usually greater than the external diameter of clutch gear, and water pump just is installed in a side of right crankcase internal clutch, water pump gear and clutch gear are the helical teeth engagement, drive pump operation (as shown in Figure 2) by clutch gear.When the assembling water pump, owing to clutch housing block and water pump gear and clutch gear are the reason of helical teeth, water pump can not be done as a wholely to install between right crankcase cover and right crankcase, can only will be with the water pump spindle of water pump gear to be installed on the right crankcase earlier earlier, again water pump body, oil sealing, seal ring and bearing etc. being assembled to right crankcase respectively covers, when the lid right crankcase cover, just finish the assembling of whole water pump at last, because each part is installed for disperseing, not only waste time and energy, and assembly quality is difficult to guarantee.
The model utility content
The purpose of this utility model provide a kind of on high-power cooling motorcycle engine water assembling easily and can guarantee the water-cooling motorcycle engine water pump of assembly quality.
For this reason, water-cooling motorcycle engine water pump described in the utility model, comprise water pump spindle, water pump body, water pump gear and impeller, impeller is installed in of water pump spindle, water pump gear is installed in the other end of water pump spindle, and water pump body on the water pump spindle and between impeller and water pump gear, is equipped with water seal and oil sealing by Bearing Installation in the water pump body, water pump spindle is two-section before and after being broken as near the water pump gear place, is respectively equipped with the connection groove that matches in the end face junction of front and back two-section and is connected boss.
Above-mentioned connection groove is a U-groove bevel, and the front and back two-section open end of water pump spindle is supported in the water pump body by little bearing or big bearing respectively.
The utility model is with water pump spindle two-section before and after being broken as near the water pump gear place, that section that water pump gear will be installed earlier during assembling is assembled on the right crankcase, remaining part can be assembled into earlier by water pump manufacturer and be installed in right crankcase again after the integral body and cover, can guarantee the assembly quality of water pump self like this, and reduce the operation of on motor, assembling water pump, make assembling simple.When right crankcase cover and right crankcase are linked, connection boss on only need making wherein one section stretches in the connection groove of another section, two-section is docking together before and after making, and prevent that them from relatively rotating, on gyratory directions, just water pump spindle is joined for an integral body, do not influence the transmission of water pump spindle moment.
The beneficial effects of the utility model are: reduced on motor the operation of assembling water pump, made the assembling work of water pump simple, easily, and helped to guarantee the assembly quality of water pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is after the water pump 16 before improving is installed in the motor described in the utility model and the position of clutch 9 concerns schematic representation.
Among the figure: impeller 1 water seal 2 water pump bodys 3 water pump spindles 4 connect groove 4a and connect boss 4b oil sealing 5 water pump gears 8 clutches 9 little bearing 11 big bearing 12 clutch gears 15 water pumps 16 right crankcase covers 17
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, impeller 1 is installed in of water pump spindle 4, water pump gear 8 is installed in the other end of water pump spindle 4, water pump body 3 by Bearing Installation on the water pump spindle 4 and between impeller 1 and water pump gear 8, water seal 2 and oil sealing 5 are housed in the water pump body 3, water pump spindle 4 is two-section before and after being broken as near water pump gear 8 places, is respectively equipped with the connection groove 4a that matches in the end face junction of front and back two-section and is connected boss 4b.
It is U-groove bevel that Fig. 1 illustrates connection groove 4a, also can be other shape, as long as can the two-section butt joint of convenient front and back install, and it is just passable to prevent that them from relatively rotating, the front and back two-section open end of water pump spindle 4 is supported on the water pump body 3 by little bearing 11 or big bearing 12 respectively.
During assembling, that section that water pump gear 8 will be installed earlier is assembled on the right crankcase, after can being assembled into an integral body earlier by water pump manufacturer, remaining part is installed in (with reference to Fig. 2) on the right crankcase cover 17 again, can guarantee the assembly quality of water pump self like this, and reduce the operation of on motor, assembling water pump, make assembling simple.When right crankcase cover 17 and right crankcase were linked, the connection boss 4b on only need making wherein a section stretched among the connection groove 4a of another section, and two-section is docking together before and after making.
