Specific implementation mode
Below in conjunction with the accompanying drawings, the specific implementation mode of the present invention is described in detail, it is to be understood that the guarantor of the present invention Shield range is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members Part or other component parts.
As shown in Figure 1 to Figure 3, Fig. 1 is the sectional view that gear shaft according to the present invention is combined with positioning pin.Fig. 2 is basis The combination stereogram of the gear shaft and positioning pin of the present invention.It is another that Fig. 3 is that gear shaft according to the present invention is combined with positioning pin The stereogram at visual angle.According to a kind of gear shaft of the specific embodiment of the invention, it is used for 3 location and installation of gear in cylinder block On 4, there is pin hole 41 and multiple screw holes 42, gear shaft includes axis body portion 1 and positioning pin 2 in cylinder block 4.Axis body portion 1 is in Discoid, 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;Mounting hole 12 with Location hole 11 is situated coaxially within the center in axis body portion 1, and the diameter of mounting hole 12 is more than the diameter of location hole 11;Axis body portion 1 Further include multiple through-holes 13, be distributed evenly in around location hole 11, axis body portion 1 is to pass through multiple lead to by multiple bolts 5 Axis body portion 1 is fixed on multiple screw holes 42 of cylinder block 4 by hole 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 invention.Fig. 5 is basis Gear shaft, positioning pin, the gear of the present invention are assemblied in the sectional view of cylinder block.In some embodiments, positioning pin 2 includes fixed Position section 21, positioning section 21 are located at one end of positioning pin 2, and positioning section 21 is installed in the pin hole 41 of cylinder block 4 after location hole 11 It is interior.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 include interlude 22 and thread segment 23.Interlude 22 is located at the centre position of positioning pin 2, and the diameter of interlude 22, which is more than, to be determined The diameter of position section 21;Thread segment 23 is located at the other end of positioning pin 2, and a part for thread segment 23 protrudes from outside gear shaft;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 invention, positioning pin, gear are assemblied in the front of cylinder block Schematic diagram.Fig. 7 is that gear shaft according to the present invention, positioning pin, gear are assemblied in the schematic top plan view of cylinder block.Fig. 8 is basis The gear shaft of the present invention, the dismounting schematic diagram in proper order of positioning pin, bolt, gear.In some embodiments, the spiral shell of positioning pin 2 A part for line section 23 will protrude from outside gear shaft, and the purpose designed in this way is the effect of the thread segment 23 of positioning pin 2 It is the dismounting for positioning pin 2.Because the mounting means of traditional gear 3, gear shaft is, first by gear shaft bolt 5 and calmly Position pin 2 is fixed on allowed in cylinder block 4 after axial direction again by gear 3 along gear shaft be installed on gear shaft, when dismounting is also Gear 3 first is removed along the axial direction of gear shaft, then dismantles gear shaft again.So, above-mentioned dismounting mode is only limited to 3 He of gear The enough operating modes of the installation control of gear shaft, but if when installation space is very restricted, traditional installation and removal 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 present invention, this screw thread at this time A part for section 23 protrudes from gear shaft, and purpose is just to be able to be connected with disassembling fixture, then utilizes tooling that will position 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 present invention has the advantages that compared with prior art:Simple in structure, manufacture is held Easily, 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 present invention is in order to illustrate and illustration purpose.These descriptions It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed And variation.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the present invention and its actually answering With so that those skilled in the art can realize and utilize the present invention a variety of different exemplary implementation schemes and Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
