Abstract
The utility model provides a water pump axle, belongs to machinery for the manufacturing of immersible pump. The axis body is six positive arris rhabodoids, has the assembly screw thread in the one end of axle, has set up a circular check ring at the other end, and the external diameter of retaining ring is the same with the external diameter of axis body, and the axis body is in the same place with the retaining ring is fixed. It is all very convenient to process and adorn, unload.
Description
Technical field: a kind of pump shaft, belongs to mechanical field, for the manufacture of immersible pump.
Background technology: axle is the strength member in water pump, in the prior art, pump shaft is to pass through
The center screw screw of axle one end and shaft joint are fixed together, or the screw with shaft joint side
It is fixed together with projection key screw.In order to prevent loosening of center bolt, many producers adopt
Stick with glue agent screw sealing is good, so, be just completely fixed together between pump shaft and shaft joint
, not only trouble during assembling, the dismounting when maintenance the most more bothers, and torch adhesive to be used burns
Axle or shaft joint could be changed after change.
Summary of the invention: in multistage pump, is installed in series by multiple stators, and pump shaft plays connection leaf
The parts such as sheet, stator and the effect of transmission power.In the prior art, pump shaft is to pass through axle
The center screw screw of one end and shaft joint are fixed together, or with the screw of shaft joint side and
Projection both key screws are fixed together.In order to prevent loosening of center bolt, many producers use
Adhesive is good screw sealing, so, is just completely fixed together, no between axle and shaft joint
But trouble during assembling, the dismounting when maintenance the most more bothers, after burning with torch adhesive
Axle and shaft joint could be taken apart, change certain part therein.
This utility model have employed a kind of new structure design, can overcome of the prior art one
A little defects, improve the efficiency of loading and unloading, reduce processing cost.
A kind of pump shaft, it is characterised in that: axis body 1 is positive six rib rhabodoids, at axis body 1
One end is provided with a circular stage, this stage has assembling screw thread, is provided with one at the other end
Individual circular collar 2, the external diameter of back-up ring 2 is identical with the external diameter of axis body 1, and axis body 1 and back-up ring 2 are solid
It is scheduled on together.Shaft joint 3 is hollow cylindrical, and inside is divided into two sections, and one section has hexagonal endoporus
31, can match with pump shaft 1, another section has circular inner hole 32, and inwall has strip fin,
Can coordinate with motor shaft.
As long as pump shaft 1 being injected from shaft joint circular inner hole 32 during assembling, in hexagonal
It is the most permissible that head is moved in hole 31 to, and owing to back-up ring 2 cannot pass through hexagonal endoporus 31, shaft joint 2 is not
Can skid off from pump shaft 1, owing to being also equipped with guide vane shell, stator, impeller etc. on pump shaft 1,
Shaft joint 2 also will not slide to the opposing party, as long as laying down the assembling screw of the other end, water during dismounting
Pump shaft just can pull out, install, dismantle the most very convenient.
Suitable hexagon shaped steel is chosen man-hour as long as adding, in one stage an of turning therein,
And car goes out screw thread, other end is lathed a stage on shield ring sleeve, then back-up ring and axis body are welded in
The most just complete.
Accompanying drawing illustrates: Fig. 1 is the structural representation of pump shaft, and Fig. 2 is the left diagram of Fig. 1,
Fig. 3 is the cooperation figure of axle and shaft joint, Fig. 4 be the structural representation of existing axle, Fig. 5 be Fig. 4
Left view, Fig. 6 is the right view of shaft joint 3, in figure: 1 axis body, 2 back-up rings,
3 shaft joints, 31 hexagonal endoporus, 32 circular inner holes.
Detailed description of the invention: a kind of pump shaft, axis body is positive six rib rhabodoids, at axis body 1
One end is provided with a circular stage, this stage has assembling screw thread, is provided with one at the other end
Individual circular collar 2, the external diameter of back-up ring 2 is identical with the external diameter of axis body 1.As long as adding man-hour to choose conjunction
Suitable hexagon shaped steel, and car goes out screw thread, other end car in one stage an of turning therein
It is whittled into a stage on shield ring sleeve, more just completes welded together to back-up ring and axis body.
