Location and installation in cylinder block 4 there is pin hole 41 and multiple screw holes 42, gear shaft to include axis body portion 1 and determine in cylinder block 4
Position pin 2.Axis body portion 1 is in the form of annular discs, and axis body portion 1 includes location hole 11 and mounting hole 12.Location hole 11 is located at the center in axis body portion 1
Position；Mounting hole 12 is situated coaxially within the center in axis body portion 1 with location hole 11, and the diameter of mounting hole 12 is more than location hole 11
Diameter；Axis body portion 1 further includes multiple through-holes 13, is distributed evenly in around location hole 11, and axis body portion 1 is by multiple spiral shells
Axis body portion 1 is fixed on multiple screw holes 42 of cylinder block 4 by bolt 5 by multiple through-holes 13.
As shown in Fig. 4 to Fig. 5, Fig. 4 is the structural schematic diagram of the positioning pin of gear shaft according to the present utility model.Fig. 5 is
Gear shaft according to the present utility model, positioning pin, gear are assemblied in the sectional view of cylinder block.In some embodiments, it positions
Pin 2 includes positioning section 21, and positioning section 21 is located at one end of positioning pin 2, and positioning section 21 is installed in cylinder block 4 after passing through location hole 11
Pin hole 41 in.Wherein positioning section 21 is axis body portion 1 to be located in the pin hole 41 of cylinder block 4.In some embodiments,
Positioning pin 2 further includes interlude 22 and thread segment 23.Interlude 22 is located at the centre position of positioning pin 2, interlude 22 it is straight
Diameter is more than the diameter of positioning section 21；Thread segment 23 is located at the other end of positioning pin 2, and a part for thread segment 23 protrudes from gear shaft
Outside；Wherein thread segment 23 is used for the dismounting of positioning pin 2.
Referring again to Fig. 1 to Fig. 5, in some embodiments, the positioning section 21 of positioning pin 2 and the pin hole 41 of cylinder block 4
Coordinated using transition.The positioning section 21 of positioning pin 2 is gap-matched with the location hole 11 of gear shaft.Interlude 22 is installed in peace
It fills in hole 12, the dress of interlude 22 and mounting hole 12 are clearance fits.
As shown in Figure 6 to 8, Fig. 6 is that gear shaft according to the present utility model, positioning pin, gear are assemblied in cylinder block
Front schematic view.Fig. 7 is that gear shaft according to the present utility model, positioning pin, gear are assemblied in the schematic top plan view of cylinder block.Figure
8 be the dismounting schematic diagram in proper order of gear shaft according to the present utility model, positioning pin, bolt, gear.In some embodiments,
A part for the thread segment 23 of positioning pin 2 will protrude from outside gear shaft, and the purpose designed in this way is the screw thread of positioning pin 2
The effect of section 23 is the dismounting for positioning pin 2.Because the mounting means of traditional gear 3, gear shaft is first to use gear shaft
Bolt 5 and positioning pin 2 are fixed on allowed in cylinder block 4 after axial direction again by gear 3 along gear shaft be installed on gear shaft, tear open
It is also first to remove gear 3 along the axial direction of gear shaft when unloading, then dismantles gear shaft again.So, above-mentioned dismounting mode only limits
In the operating mode that the installation control of gear 3 and gear shaft is enough, but if when installation space is very restricted, traditional peace
Assembly and disassembly technique just cannot be satisfied.
Referring to Fig. 6 to Fig. 8, as shown in figure 5, in 3 installation site of gear of the present embodiment, because of cylinder block 4
There are the blockings of location A, make gear 3 that can not be installed along the axial direction of gear shaft according to traditional mounting process, tooth
Wheel 3, which can only be pushed away according to the signal direction of Fig. 6 arrows from the radial direction of gear 3, is put into position, then again by gear shaft along its axis
It is fitted into direction in the axis hole of gear 3, is finally inserted positioning pin 2, blending bolt 5 is fixed.Sequence when dismounting is first to dismantle spiral shell
Bolt 5 extracts positioning pin 2, then in axial direction unloads gear shaft, finally radially removes gear 3 again.But due to fixed
Coordinate for transition between the positioning section 21 and the pin hole 41 of cylinder block 4 of position pin 2, cooperation is tighter, it is necessary to just removable by tooling
It unloads, how that tooling occurs to connect with positioning pin 2, has just used the thread segment 23 of the positioning pin 2 of the utility model at this time, this
A part for thread segment 23 protrudes from gear shaft, and purpose is just to be able to be connected with disassembling fixture, then utilizes tooling will
Positioning pin 2 is extracted from pin hole 41, after the completion of positioning pin 2 is dismantled, could carry out the dismounting of gear 3.
In conclusion the gear shaft of the utility model has the advantages that compared with prior art：Simple in structure, system
It makes easy, easy to spread；Standard is simple, convenient disassembly and the dual function with positioning and dismounting.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of different examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
