Abstract
The utility model discloses a kind of dedicated splined shaft of water pump, including spline interstage sleeve and splined shaft, the outer wall end of splined shaft is provided with step, and step is meshed cooperation with spline interstage sleeve.Step is extrusion forming step.The utility model replaces the function of circlip using step, will not destroy the overall structure of pump shaft, and without groove, pump shaft is not easy to break, long service life, and easy to operate, high-efficient without using lathe, at low cost.It can be widely used in various pump equipments.
Description
Technical field
The utility model relates to pump shafts to manufacture and design field, in particular to a kind of dedicated splined shaft of water pump.
Background technique
Pump shaft is component part important in water pump, and impeller is mounted on pump shaft, so must in pump shaft spline root position
Spline interstage sleeve must be installed, be fixed on impeller on splined shaft.Pump shaft is connected to motor, motor moving axis rotation, pump shaft band movable vane
Wheel rotation.Since all loads are all on pump shaft, so the intensity and durability of pump shaft are critically important.
Usual splined shaft is to open a jump-ring slot with numerically controlled lathe in splined end, and circlip is installed in jump-ring slot, will be spent
Key interstage sleeve is stuck on circlip, fixes spline interstage sleeve, so as to install impeller.The axis is designed due to opening card on the whole in axis
Spring slot destroys the overall structure of axis, makes axis be easy to be broken in the position of jump-ring slot, service life is not grown.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of long service life, the dedicated spline of water pump easy to operate
Axis.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of dedicated splined shaft of water pump, including spline interstage sleeve and splined shaft, the outer wall end of the splined shaft are provided with
Step, the step are meshed cooperation with spline interstage sleeve.
Preferably, the step is extrusion forming step.
By adopting the above technical scheme, due to not destroying the overall structure of pump shaft using fashion of extrusion extrusion step, so that
Pump shaft is not easy to break, long service life.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1- spline interstage sleeve, 2- splined shaft, 3- step.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, a kind of dedicated splined shaft of water pump, including spline interstage sleeve 1 and splined shaft 2, the outer wall end of splined shaft 2
Place is provided with step 3, and step 3 is meshed cooperation with spline interstage sleeve 1.
Wherein, step 3 is extrusion forming step.
Principle: the splined shaft 2 of the utility model be 2 end of splined shaft using squeeze by the way of, squeeze out step 3, generation
For the function of circlip, be meshed cooperation with spline interstage sleeve 1.Due to squeezing out step using fashion of extrusion, the whole of pump shaft is not destroyed
Body structure, so that pump shaft is not easy to break, long service life.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
