Abstract
The utility model discloses a water pump with a pump shaft and an impeller in splined joint. The water pump comprises a pump body and an impeller positioned and mounted inside the pump body through the pump shaft, wherein the impeller and the pump shaft are connected in a way that a spline inner bore and a spline shaft are in matched connection, the inner bore of the impeller serves as a splined hole, and the spline shaft is arranged at the matching and installation part of the pump shaft and the impeller. Therefore, when in work, the impeller can carry out axial sliding automatically along the pump shaft according to pressure difference on two sides of the impeller, and is positioned in a pressure balancing point (the optimal working position of impeller); and not only is the torsion loaded, but also the performance and the reliability of the water pump are increased.
Description
Technical field
The utility model relates to a kind of water pump, is the water pump that is connected and connects for spline between a kind of pump shaft and the impeller thus.
Background technique
In the prior art, the small pump pump shaft generally is connected to come transmitting torque by interference fit with impeller, and during for pump working, require the impeller can be poor according to pressure at both sides, automatically be in axial sliding along pump shaft, and be positioned to the water pump of pressure balance point (working position of impeller the best), if adopt interference fit, when then impeller is worked, cannot do axial slip along pump shaft, therefore, the performance and the functional reliability of water pump have greatly been influenced.
The model utility content
The utility model is at the deficiencies in the prior art, the water pump that provides a kind of pump shaft-impeller spline to connect, it is connected by the mode that will adopt spline-splined shaft to be connected between the pump shaft of water pump and the impeller, when then impeller is worked, can be poor according to its pressure at both sides, automatically be in axial sliding, and be positioned to pressure balance point (working position of impeller the best) along pump shaft, so both carry moment of torsion, improved the Performance And Reliability of water pump again.
For realizing above technical purpose, the utility model will be taked following technological scheme:
The water pump that a kind of pump shaft-impeller spline connects, comprise the pump housing and pass through the impeller of pump shaft location and installation in pump case, described impeller is connected by the mode that spline endoporus-splined shaft is connected with pump shaft, described impeller endoporus is a splined hole, and pump shaft cooperates the installation position to be set to splined shaft with impeller.
Further, described impeller endoporus is 12 tooth serration spline endoporus.
According to above technological scheme, can realize following beneficial effect:
Pump shaft described in the utility model is connected by the mode that spline endoporus-splined shaft is connected with impeller, when then impeller is worked, can be poor according to its pressure at both sides, automatically be in axial sliding along pump shaft, and be positioned to pressure balance point (working position of impeller the best), so both carry moment of torsion, improved the Performance And Reliability of water pump again.
