Abstract
The invention relates to a single-cylinder vertical air-cooled diesel engine, in particular to a cam shaft power output structure of a single-cylinder vertical air-cooled diesel engine, and belongs to the technical field of diesel engine. The cam shaft power output structure comprises a machine body and a cam shaft. A cam shaft mounting cavity is formed in the inner side of the supporting end of the machine body. The supporting end of the cam shaft extends into a cam shaft mounting hole and is connected with the inner wall of the cam shaft mounting hole in a rolling mode. An oil guiding groove is formed in the positioning end face of the cam shaft mounting hole. The cam shaft power output structure is simple, compact and reasonable, the supporting shaft diameter of the cam shaft in the cam shaft mounting hole of the machine body is increased, the bearing capacity of the cam shaft in the supporting position is improved, and the reliability of the cam shaft power output structure is improved; and meanwhile, modification of a machine body structure is small, and the technical problems of the type can be advantageously solved in a short time.
Description
Technical field
The present invention relates to a kind of single-cylinder vertical air-cooled diesel engine, specifically a kind of single-cylinder vertical air-cooled diesel engine cam
Axle power output structure, belongs to Diesel Engine Technique Field.
Background technology
To adapt to the supporting needs of power of different machineries, single-cylinder vertical air-cooled diesel engine power output is except using conventional mark
Determine outside rotating speed bent axle export structure, the camshaft export structure that also can be halved using rated engine speed sometimes.
The camshaft power output structure of existing diesel engine, the camshaft output end at its side cover is using rolling bearing
Support, body lumen end is supported using needle bearing.The moment of torsion transmitted when being exported from camshaft due to diesel powered is larger, plus
OHC still suffers from itself at work the active force that valve tappet, oil pump tappet body etc. are passed over, therefore, single cylinder stands
When formula air-cooled diesel engine adopts camshaft power output structure, needle bearing is excessive because of the load born, and its reliability is poor, holds
It is also easy to produce the phenomenons such as needle roller abrasion, retainer damage.
The content of the invention
It is an object of the invention to overcome above-mentioned weak point, it is convex so as to provide a kind of single-cylinder vertical air-cooled diesel engine
Wheel shaft power export structure, increased the bearing capacity at camshaft body lumen end support, improve camshaft power output knot
The reliability of structure.
According to the technical scheme that the present invention is provided, a kind of single-cylinder vertical air-cooled diesel engine camshaft power output structure includes
Body and camshaft, are provided with camshaft in body, camshaft is provided with timing gears；The side cover end connection side cover of body, side cover
Rolling bearing installation cavity is inside provided with, rolling bearing, the side cover end connection rolling bearing of camshaft are provided with rolling bearing installation cavity
And stretch out outside body from side cover, it is characterized in that：The support end inner side of body is provided with camshaft installing hole, and the support end of camshaft is stretched
Enter in camshaft installing hole and roll with camshaft installing hole inwall to be connected, the positioning end face of camshaft installing hole is provided with and draws oil
Groove.
Further, camshaft installing hole front end is provided with positioning end face, and positioning end is in the face of the body support end of camshaft
Position is positioned.
Further, it is provided with oil sealing between the side cover end of camshaft and side cover to be sealed.
Compared with the prior art the present invention has advantages below：
Present configuration is simple, compact, reasonable, increases the support diameter of axle of the camshaft in the camshaft installing hole of body, strengthens
Bearing capacity of the camshaft at the support, improves the reliability of camshaft power output structure；Meanwhile, to housing construction
Change it is less, be conducive to being solved in the short period technical problem that the type is present.

Position end face, 8- camshaft installing holes, 9- draw oil groove, 10- rolling bearing installation cavitys.
Specific embodiment
Below the present invention is further described the embodiment combined in accompanying drawing：
As shown in Figure 1 and 2, the invention mainly comprises body 1 and camshaft 2, the side cover end connection side cover 5 of body 1, set in side cover 5
Have in rolling bearing installation cavity 10, rolling bearing installation cavity 10 and be provided with rolling bearing 4.The support end inner side of body 1 is provided with cam
Axle installation cavity 8.
Camshaft 2 is provided with body 1, camshaft 2 is provided with timing gears 3, the side cover end connection rolling bearing of camshaft 2
4 and stretch out outside body 1 from side cover 5.Oil sealing 6 is provided between the side cover end of the camshaft 2 and side cover 5 to be sealed.
The support end of camshaft 2 is stretched in camshaft installing hole 8 and is slidably connected with the inwall of camshaft installing hole 8.It is described
The front end of camshaft installing hole 8 is provided with positioning end face 7, and positioning end face 8 is positioned to the position of the body support end of camshaft 2.
The positioning end face 7 of the camshaft installing hole 8 is provided with and draws oil groove 9, and machine oil is introduced to the friction by drawing oil groove 9
Pair is lubricated.
The present invention compared with prior art, increases the support diameter of axle of the camshaft in the camshaft installing hole of body, strengthens
Bearing capacity of the camshaft at the support, improves the reliability of camshaft power output structure.Meanwhile, to housing construction
Change it is less, be conducive to being solved in the short period technical problem that the type is present.
