Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1 to Figure 3, Fig. 1 is that the front view structure of PTO gear engagement structure according to an embodiment of the present invention is shown
It is intended to；Fig. 2 is the backsight structural representation of PTO gear engagement structure according to an embodiment of the present invention；Fig. 3 is according to this hair
The schematic diagram of the section structure of the intermediate idler gear of the PTO gear engagement structure of a bright embodiment.
A kind of PTO gear engagement structure according to the preferred embodiment of the present invention, comprising: intermediate idler gear 1, bell housing 2
And PTO gear 3.The both ends of intermediate idler gear 1 offer 12 hole of 11 hole of the first positioning pin and the second positioning pin respectively, and intermediate
One end of idle gear 1 is fixed in cylinder block by the cooperation in 11 hole of the first positioning pin 11 and the first positioning pin；Bell housing 2 passes through
Second positioning pin 12 cooperation corresponding with 12 hole of the second positioning pin of intermediate idler gear 1, so that it is intermediate lazy to be fixed on bell housing 2
On gear 1, and first positioning hole 21 is offered on bell housing 2；And PTO gear 3 is solid by the first positioning hole 21 of bell housing 2
Due on bell housing 2, and PTO gear 3 is engaged with intermediate idler gear 1.
In a preferred embodiment, be also provided with second location hole 22 on bell housing 2, and second location hole 22 to
Cooperation corresponding with the second positioning pin 12 and 12 hole of the second positioning pin；First positioning pin, 11 hole and 12 hole of the second positioning pin are opened respectively
Set on the intermediate position at the both ends of intermediate idler gear 1；First positioning pin, 11 hole and 12 hole of the second positioning pin are coaxial.
In practical applications, PTO gear engagement structure technical problems to be solved of the invention are according to engine gear
System's arrangement, by guaranteeing the concentricity of the first positioning pin 11 and the second positioning pin 12, to accurately control PTO gear 3 and centre
The back lash of idle gear 1 reduces biggish the making an uproar when gear train works due to the generation bigger than normal of PTO gear 3 and idle gear gap
Sound.Specifically: PTO gear engagement structure of the invention includes: intermediate idler gear 1, bell housing 2 and PTO gear 3.It is intermediate
Idle gear 1 is located in cylinder block by the first positioning pin 11, and the second positioning pin 12 is used to position bell housing 2, passes through control
(positioning of PTO gear 3 stops for the concentricity of first positioning pin 11 and the second positioning pin 12 and first positioning hole 21 on bell housing 2
Mouthful) and second location hole 22 between tolerance, to control the back lash between PTO gear 3 and intermediate idler gear 1, by
It is to be positioned by the first positioning hole 21 (3 positioning spigot of PTO gear) of bell housing 2, and bell housing 2 is logical in PTO gear 3
Intermediate idler gear 1 (second location hole 22 is inserted into the second positioning pin 12) Lai Dingwei is crossed, is equivalent to only two sizes in this way
Chain thus can accurately guarantee tolerance to greatly reduce the dimension chain of 3 positioning spigot of PTO gear, if the first positioning pin
11 holes and 12 hole of the second positioning pin connect, that is, drill the axle bed of intermediate idler gear 1, and such first positioning pin 11 and second is fixed
Position pin 12 be equivalent to be it is coaxial, thus only need to control the tolerance of first positioning hole 21 and second location hole 22, energy
Control gear back lash, as soon as that is, only need a wheel chain, the back lash of such gear can control smaller；And
And the first positioning pin 11 and the second positioning pin 12 of intermediate idler gear 1, or (be integrated on 1 axis of intermediate idler gear) as one,
Or separately do, or idler shaft center is drilled, it is inserted into a pin.
In short, PTO gear engagement structure of the invention, simple and reasonable, PTO gear is positioned by bell housing seam allowance,
And bell housing is positioned by intermediate idler gear, so entire dimension chain quantity is substantially reduced, so as to greatly reduce PTO
The distance between gear and intermediate idler gear tolerance, that is, greatly reduce the engagement between PTO gear and intermediate idler gear
Gap greatly reduces gear drive bring noise.
The aforementioned description to specific exemplary embodiment of the 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 specific principle of the invention and its actually answering
With so that those skilled in the art can be realized and utilize a variety of different exemplary implementation schemes of the invention and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
