Abstract
The utility model relates to a kind of aluminum alloy water pump vane, comprise the impeller matrix of die cast, the central position of described impeller substrates forms six prisms extended straight up, the top of described six prisms is flat-top, the bottom center position of described impeller matrix is provided with a shoulder hole, the miner diameter end of shoulder hole to extend in six prisms and arranges internal thread, the thickness of described impeller matrix reduces to base circumferential gradually from six prism lower ends, in reclinate cambered surface, described impeller matrix is distributed with in the shape of a spiral multiple blade being bent to base circumferential in involute, each blade extends straight up, the extended height of the corresponding one end of base circumferential of each blade and one end of corresponding six prisms is respectively lower than the middle part extended height of involute segmental arc.The height of impeller of the present utility model is lower, reduces the whole height of water pump, prevents the pin of driver and water pump cover from interfering, facilitates driver's operation.
Description
Technical field
The utility model relates to Water pump for engine of motor cycle field, particularly a kind of aluminum alloy water pump vane.
Background technique
See Fig. 3, for current and that right crankcase of motorcycle engine is supporting water pump aluminum alloy impeller, the diameter of this kind of aluminum alloy impeller is less, six prisms on impeller matrix are dome, for ensureing that the pump water yield is sufficient, the height being arranged on six prisms on impeller matrix and aluminum alloy impeller need be increased, when this kind of aluminum alloy impeller installed by water pump, the height of water pump cover increases, and water pump whole height is increased.When water pump is arranged on engine right crankcase, because the height of water pump is higher, the height of right crankcase cover of engine is increased, motor is arranged on after on frame of motorcycle, right crankcase cover of engine is near pedal position, driver is in driving procedure, and pin and water pump cover interfere, extremely inconvenient driver's operation.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and provide a kind of aluminum alloy water pump vane, the height of impeller is lower, reduces the whole height of water pump, prevents the pin of driver and water pump cover from interfering, facilitates driver's operation.
The technical solution of the utility model is: a kind of aluminum alloy water pump vane, comprise the impeller matrix of die cast, the central position of described impeller substrates forms six prisms extended straight up, the top of described six prisms is flat-top, the bottom center position of described impeller matrix is provided with a shoulder hole, the miner diameter end of shoulder hole to extend in six prisms and arranges internal thread, the thickness of described impeller matrix reduces to base circumferential gradually from six prism lower ends, in reclinate cambered surface, described impeller matrix is distributed with in the shape of a spiral multiple blade being bent to base circumferential in involute, each blade extends straight up, the extended height of the corresponding one end of base circumferential of each blade and one end of corresponding six prisms is respectively lower than the middle part extended height of involute segmental arc.
Angle α corresponding to described blade involute segmental arc is 45-55 degree.
The quantity of described blade is six.
The diameter D of described impeller matrix is greater than the height H of six prisms.
Adopt technique scheme: a kind of aluminum alloy water pump vane, comprise the impeller matrix of die cast, the central position of described impeller substrates forms six prisms extended straight up, and the top of described six prisms is flat-top, and six prisms of flat-top are lower than six prism heights of dome.The bottom center position of described impeller matrix is provided with a shoulder hole, and the miner diameter end of shoulder hole to extend in six prisms and arranges internal thread, and the shoulder hole of water pump vane is fixedly connected with rotatingshaft by screw thread.The thickness of described impeller matrix reduces to base circumferential gradually from six prism lower ends, in reclinate cambered surface, described impeller matrix is distributed with in the shape of a spiral multiple blade being bent to base circumferential in involute, each blade extends straight up, and the extended height of the corresponding one end of base circumferential of each blade and one end of corresponding six prisms is respectively lower than the middle part extended height of involute segmental arc.
Be further described below in conjunction with the drawings and specific embodiments.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
Fig. 3 is the structural representation of current water pump aluminum alloy impeller.
In accompanying drawing, 1 is impeller matrix, and 2 is six prisms, and 3 is shoulder hole, and 4 is blade.
Embodiment
See Fig. 1 and Fig. 2, a kind of aluminum alloy water pump vane, comprise the impeller matrix 1 of die cast, central position above described impeller matrix 1 forms six prisms 2 extended straight up, the top of described six prisms 2 is flat-top, six prisms and impeller matrix are integrated die cast, and the diameter D of impeller matrix is greater than the height H of six prisms.The bottom center position of described impeller matrix 1 is provided with a shoulder hole 3, and the miner diameter end of shoulder hole 3 to extend in six prisms 2 and arranges internal thread, and the bigger diameter end of shoulder hole 3 is positioned at the bottom surface of impeller matrix.The thickness of described impeller matrix 1 reduces to base circumferential gradually from six prism 2 lower ends, what make impeller matrix is reclinate cambered surface above, described impeller matrix 1 is distributed with in the shape of a spiral multiple blade 4 being bent to base circumferential in involute, angle α corresponding to described blade 4 involute segmental arc is 45-55 degree, in the present embodiment, the quantity of blade 4 is six, and the angle α corresponding to blade involute segmental arc is 52 degree.These blades are arranged on the position between six prisms and base circumferential, leave span between one end of corresponding six prisms of blade and six prisms.Each blade 4 extends straight up, and the extended height of one end of the corresponding base circumferential of each blade 4 and one end of corresponding six prisms, respectively lower than the middle part extended height of involute segmental arc, makes the middle part of blade segmental arc be downward-sloping inclined-plane to the two ends of blade.
When the utility model uses, the shoulder hole of impeller is fixedly connected with rotatingshaft by screw thread, because the height of blade and six prisms all reduces, when this kind of impeller is installed, the thickness of water pump can be reduced, effectively prevent the pin of water pump cover and driver from interfering, ensure driver's normal running.
