Cooperatively form gear, the supporting part side wall circumferentially on be uniformly provided with multiple stopper slots, the stopper slot crosses at vertically
In the supporting part side wall, the stopper slot can be the structure such as outer small interior big taper or " ⊥ " font, the tooth with it is described
Spacing groove location sum amount corresponds, and the root portion of the tooth is provided with the limited block coordinated with the stopper slot, described spacing
For block along the stopper slot axially with the stopper slot socket connection, the length of the tooth is identical with the supporting part length, in order to
Tooth is prevented to be axially moveable on supporting part, the supporting part both ends, which are sticked, the spacing ring, and the spacing ring is sheathed on
On the connecting portion, the limit ring outer diameter is identical with the supporting part diameter, and the spacing ring connects with the connecting portion screw thread
Connect, tooth is fixed on supporting part by the cooperation of spacing ring and stopper slot.By tooth and axle split settings, in part odontotripsis
When, the tooth of abrasion need to be only changed, unworn tooth need not be changed, and greatly save production cost.
Further, the angle between the crest top land of the tooth and side is right angle.Gear pump by driving gear with it is driven
Gear continuous engagement and disengagement, the swept volume for causing to be formed between pumping cylinder and gear change, and convey liquid or are allowed to increase
Pressure, the more close of two gears and pumping cylinder assembling is usually required that, between avoiding liquid from directly flowing through between the teeth of two gears
Gap flows through gap between gear and pumping cylinder, and in order to prevent liquid from directly flowing through the gap between tooth and pumping cylinder, tooth top is not
Can chamfering.
Further, in order that driving gear shaft is rotated by motor, one end of the axle is provided with drive block, described
The one end of drive block away from the axle is provided with driver slot, and the driver slot is " one " font groove, " ten " font groove or polygon groove,
Driver slot is used to coordinate with motor output end.
Further, in order to reduce the production cost of gear shaft, the axle is provided with the through hole through the axle vertically.
The beneficial effects of the utility model are：A kind of detachable gear wheel axle provided by the utility model, using tooth and axle point
Body is set, and in part during odontotripsis, need to only change the tooth of abrasion, unworn tooth need not be changed, greatly save and be produced into
This.

Embodiment
The utility model is described in detail presently in connection with accompanying drawing.This figure is simplified schematic diagram, only in a schematic way
Illustrate basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
As Figure 1-5, a kind of detachable gear wheel axle of the present utility model, including the axle of split settings, tooth 3 and spacing ring
5, the axle includes supporting part 1 and the connecting portion 2 located at the both ends of supporting part 1, and the diameter of supporting part 1 is more than the company
The diameter of socket part 2, the side wall of supporting part 1 circumferentially on be uniformly provided with multiple stopper slots 4, the stopper slot 4 crosses at vertically
In the side wall of supporting part 1, the stopper slot 4 is outer small interior big " ⊥ " character form structure, the tooth 3 and the stopper slot 4
Put and corresponded with quantity, the root portion of the tooth 3 is provided with the limited block 9 coordinated with the stopper slot 4, the limited block 9 with
