Abstract
The utility model discloses a kind of rocker shaft bed with lubricating function, its structure is:The bolt hole of intermediate rockers seat is vertical with rocker shaft hole, and by gap oil duct is formed between bolt hole and bolt, the internal galleries of rocker arm shaft are vertical with gap oil duct.The bottom surface of intermediate rockers seat is provided with oil groove, and oil groove is communicated with bolt hole.Intermediate rockers seat is both installed to rocker arm shaft and is positioned, at the same rocker arm bracket again with rocker arm shaft, cylinder cap composition grease channel, the cam shaft for diesel engine spring bearing for overhead camshaft provides lubricating oil, it is to avoid the oil leab of processed complex on cylinder cap.Overall longer in view of 6 cylinder diesels, the lubrication of intermediate cam axle spring bearing is more difficult, so the structure is particularly well-suited to the longer type of such cylinder cap.
Description
Technical field
This utility model belongs to engine components, and in particular to a kind of rocker shaft bed for overhead camshaft diesel engine.
Background technology
Rocking arm and corresponding rocker arm shaft are the vitals in engine driving system, the design of rocker arm shaft lubricating system
Whether operation and the service life of electromotor will rationally be directly influenced.As the important motion portion of engine timing system
Part, camshaft are cooperated with rocker arm shaft and will ensure the sufficient lubrication of its motor process.The cam of many diesel engines belongs at present
Underlying structure, and for overhead cam diesel engine using this lubricating system of rocking arm lubricating system be then less suitable for.Therefore originally
Utility model proposes a kind of suitable for by the lubricating oil rocker arm shaft, being conveyed to the intermediate supports bearing fuel feeding of overhead camshaft
Structure.
The content of the invention
The purpose of this utility model is to provide a kind of for rocker shaft bed of the overhead camshaft with lubricating function, will shake
Lubricating oil in arm axle is shipped to the intermediate supports bearing of camshaft and lubricates for which.
Hereinafter principle of the present utility model and structure are illustrated.Rocker shaft bed with lubricating function, including rocker arm shaft,
Cylinder cap, rocker arm bracket bolt, camshaft and intermediate supports bearing.The bolt hole of intermediate rockers seat is vertical with rocker shaft hole, by spiral shell
Gap oil duct B is formed between keyhole and rocker arm bracket bolt.The internal galleries A of rocker arm shaft is vertical with gap oil duct B, intermediate rockers seat
Bottom surface be provided with oil groove, oil groove is communicated with bolt hole.
Lubricating oil Jing intermediate rockers seat to the path of camshaft fuel feeding is：Internal galleries A of the lubricating oil by rocker arm shaft, enters
Enter by gap oil duct B is formed between bolt hole and rocker arm bracket bolt, subsequently into the oil groove oil duct C of intermediate rockers seat bottom surface,
The downward oil duct D of Jing top surface of cylinder cover, supplies into the camshaft hole that oil duct E oblique with cylinder cap is communicated to the intermediate supports bearing of camshaft
Oil.
From in structure design, intermediate rockers seat is in addition to carrying out installing positioning to rocker arm shaft, it is important to in camshaft
Between spring bearing provide lubricating oil.Which is structurally characterized in that the bolt hole and the oil leab of oil groove composition of intermediate rockers seat, will shake
Lubricating oil in arm axle is transported on the camshaft intermediate supports bearing of cylinder cap, and the motion for camshaft provides lubricating oil, it is ensured that
Camshaft normal work in the case of sufficient lubrication.
The characteristics of this utility model and beneficial effect be, intermediate rockers seat is both installed to rocker arm shaft and positioned, rocker arm bracket again with
Rocker arm shaft, cylinder cap composition grease channel, the cam shaft for diesel engine spring bearing for overhead camshaft provide lubricating oil.Avoid
The oil leab of processed complex on cylinder cap, the structure are particularly well-suited to 6 cylinder diesels, because the type overall cylinder cover is longer, in
Between camshaft support bearing lubrication it is more difficult.
Description of the drawings
Fig. 1 is this utility model three-dimensional structure diagram.
Fig. 2 is C-C cross-section structure axonometric charts in Fig. 1.
Fig. 3 is rocker arm system fuel feeding oil channel structure schematic diagram.
Specific embodiment
Structural principle of the present utility model is described further below in conjunction with accompanying drawing and by embodiment.Band lubrication work(
Can the structure of rocker shaft bed be:The bolt hole 1 of intermediate rockers seat is vertical with rocker shaft hole 3, by shape between bolt hole and bolt
Into gap oil duct B, the internal galleries A of rocker arm shaft 4 is vertical with gap oil duct B.The bottom surface of intermediate rockers seat is provided with oil groove 2, oil groove
Communicate with bolt hole.
In order to the intermediate supports bearing for camshaft provides lubricating oil, 5 oil ducts are devised in intermediate rockers seat, i.e.,：
The downward oil duct D of the internal galleries A of rocker arm shaft, gap oil duct B, oil groove oil duct C, top surface of cylinder cover and tiltedly oil duct E.
By path of the intermediate rockers seat to intermediate supports bearing fuel feeding it is：Internal galleries A of the lubricating oil by rocker arm shaft,
Into by gap oil duct B is formed between bolt hole and rocker arm bracket bolt, subsequently into the oil groove oil duct C of rocker arm bracket bottom surface, in Jing
Cylinder cap 5 pushes up prone oil duct D, supplies into the camshaft hole that oil duct E oblique with cylinder cap is communicated to the intermediate supports bearing of camshaft
Oil.
Generally, in order that (overhead-cam design) cam shaft for diesel engine is sufficiently lubricated, need from
The two ends of cylinder cap are drilled through and are connected with body main oil gallery, and the spring bearing at camshaft two ends is lubricated.But the camshaft of centre
Spring bearing just should not directly drill and connect body main oil gallery, and so in addition to increasing the difficulty of processing of cylinder cap, key is also by shadow
Ring the intensity of cylinder cap.
This utility model passes through an intermediate rockers seat, there is provided a lubrication for intermediate cam axle spring bearing fuel feeding
Oil duct.The oil duct that gap is formed between the bolt hole and bolt of lubricating oil (along Fig. 3 directions of arrow) Jing intermediate rockers seats, in entering
Between rocker arm bracket oil groove, then the oblique oil duct of Jing cylinder caps enters intermediate cam axle spring bearing, define one it is simple, easily moisten
Slide-through road.
Used as embodiment, now on cylinder cap, oblique oil duct D bores depth 40mm, and oblique oil duct E bores depth 20mm, that is, facilitate and process again not shadow
Ring the intensity of overall cylinder cover.
