Abstract
The invention discloses a kind of gear lubrication oil circuit, applied to the gear lubrication of engine, gear lubrication oil circuit includes the gear installation end face that oil groove is cast in engine body, oil groove connection engine body main oil gallery；Gear chamber cover plate is closed together in the gear installation end of engine body, and gear chamber cover plate closes to form gear lubricant road with oil groove.The oil groove of the gear lubrication oil circuit of the present invention is formed by casting, and without machining, is reduced the processing abrasion of engine body, by multiple through holes of gear chamber cover plate, can be carried out effectively lubricating to multiple position gears.
Description
Technical field
The present invention relates to the gear lubrication oil circuit of engine art, more particularly to a kind of gear lubrication for engine.
Background technology
The sliding bearing gear designed on current body takes the mode of oil lubrication to be all the side using internal machining drilling
Formula, is connected by drilling with main oil gallery, forms the oil circuit of closing.Fig. 6 is installed according to the gear of prior art engine body
The schematic diagram at end.Fig. 7 is the schematic cross-sectional view of the gear installation end according to prior art engine body.Such as Fig. 6 and Fig. 7 institutes
Show, the gear oil duct 5 of prior art is needed by being machined into Drilling operation formation on engine body, and this results in existing
With the presence of technology its own shortcomings：1. oilhole needs machining, waste of materials and production efficiency can be caused slow, manufacturing cost is carried
It is high；2. drillable length is long, it is easily caused drill and does not position beat, cause drill to be broken.
How to solve gear lubrication oil circuit and design the cost height for relying on machining, causing, beat is slow, manufacturability is poor to ask
Topic turns into industry urgent problem to be solved.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
When the prior art for being considered as recognizing or implying the information structure in any form well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of without machining drilling, it is possible to which multiple position gears are effectively moistened
Sliding gear lubrication oil circuit.
To achieve the above object, the invention provides a kind of gear lubrication oil circuit, applied to the gear lubrication of engine, tooth
Wheel lubricant passage way includes the gear installation end face that oil groove is cast in engine body, oil groove connection engine body main oil gallery；Tooth
Engineer room cover plate is closed together in the gear installation end of engine body, and gear chamber cover plate closes to form gear lubricant with oil groove
Road.
Preferably, in above-mentioned technical proposal, gear chamber cover plate also includes at least one through hole, through hole one end connection gear profit
Lubricating oil road, the other end is to the gear in requisition for lubrication.
Compared with prior art, the present invention has the advantages that：1. oil groove casts to be formed, without machining steps；
2. drilling is reduced, it is cost-effective；3. effectively lubricating can be carried out to multiple position gears.

Embodiment
Below in conjunction with the accompanying drawings, the embodiment to the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figures 1 to 5, according to a kind of gear lubrication oil circuit of the specific embodiment of the invention, applied to engine
Gear lubrication, gear lubrication oil circuit include oil groove 1 be cast in engine body 3 gear install end face, oil groove 1 connection starts
Machine body main oil gallery 4；Gear chamber cover plate 2 is closed together in the gear installation end of engine body 3, gear chamber cover plate 2 and oil groove 1
Closure forms gear lubricant road.
In some embodiments, gear chamber cover plate 2 also includes at least one through hole, through hole one end connection gear lubricant
Road, the other end is to the gear in requisition for lubrication.
In summary, because the oil groove of the present invention is that casting is formed, without needing machining steps as prior art, reduce
Processing cost；And take oilhole to be designed on gear chamber cover plate, take the length of oilhole very short, processing technology is simple, use
This lubricant passage way is designed, and can carry out effectively lubricating to multiple position gears.
It is foregoing to the present invention specific illustrative embodiment description be 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 above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that the certain principles and its reality of the present invention should
With so that those skilled in the art can realize and using the present invention a variety of exemplaries and
A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
