To achieve these goals, the technical solution used in the present invention is as follows:
A kind of Water pump for engine of motor cycle assembly, including impeller, water pump body and pump shaft, pump shaft is arranged in water pump body inner chamber by bearing, and pump shaft two ends pass from water pump body, impeller is arranged on pump shaft one end, and the pump shaft other end is for being connected to be driven it to rotate by motor with motor.The external diameter that described water pump body connects that end of motor near pump shaft is equal diameter structure; Detachably being provided with water pump cover at the water pump body other end, impeller is enclosed in the cavity between water pump body and water pump cover by water pump cover, is provided with the water inlet connected with described cavity and for installing the installing hole of water pump complement on water pump cover.
Described water pump body is installed that end of water pump cover and is formed with the dish edge being easy to assembling, and water pump cover is arranged on Pan Yanshang by bolt, is provided with sealing ring between dish edge and water pump cover faying face; Described installing hole is located at Pan Yanshang.
Water seal and oil sealing it is additionally provided with between water pump body and pump shaft.
Installing impeller section on pump shaft and be formed with step, impeller screw thread is screwed on pump shaft, and the pump shaft between impeller and step is set with packing ring, and packing ring is pressed between step and impeller in case uppermost leaf wheel loosens.
The endoporus that water pump body connects that end of motor near pump shaft is shoulder hole, and described bearing is arranged in this shoulder hole large aperture, is provided with back-up ring draw-in groove on pump shaft, is embedded with back-up ring in back-up ring draw-in groove, and described bearing is pressed between back-up ring and the step of shoulder hole.
Described bearing is two sets, and the pump shaft between two set bearings is provided with lining.
Tradition water pump is integrated with water pump cover and forms new water pump complement by the present invention, and the water pump complement after improvement can be directly installed on body as a complete entirety. Compared to existing technology, there is advantages that
1, water pump complement has directly just assembled in parts factory, it is simple to completes the tests such as the sealing of water pump, flow, just dispatches from the factory and install after test passes, it is to avoid install meaningless the doing over again that after on the engine, re-test is brought.
2, this integral water pump is more convenient when with engine assembly, technique is simple, have only to, either directly through bolt, pump cover is fixed on body (casing, case lid) above, baffle plate etc part need not be installed, without dismounting water pump vane and secondary installing, it is to avoid cause water pump complement secondary damage.
3, in after-sales service, it is easier to maintenance, only needs integral replacing or open pump cover portion and change, not needing to dismantle other engine part.
