Abstract
The utility model relates to a cooling and lubricating structure for an internal combustion engine swinging arm supporting seat. The circumference of one supporting end of the cam shaft of the internal combustion engine is provided with a helical groove; a supporting seat corresponding to the supporting end is provided with an oil transferring hole; an oil transferring pipe is connected with the oil transferring hole; the oil transferring pipe is communicated with a swing arm bushing ultimately to comprise the pressure lubricating structure. Compared with the existing splash lubricating, the cooling and lubricating structure for an internal combustion engine swinging arm supporting seat not only ensures that the lubricant can be sufficiently supplied when lubricating, and the more important is that the inexhaustible lubricant can act the cooling function on the swing arm bushing and the swing arm supporting seat of the swing arm bushing, and the lubricant of the cooling and lubricating structure for an internal combustion engine swinging arm supporting seat can not be heated to generate the carbonized harmful consequence. The service life of the swing arm bushing is naturally prolonged. Therefore, the accuracy of the valve timing of the internal combustion engine can be held for a long time; the internal combustion engine has easy starting, normal air exhaust and stable over-all performance.
Description
Technical field
The utility model relates to the rocker arm support of internal-combustion engine, specifically is the cooling and the lubricating structure of internal-combustion engine rocker arm support.The cooling and the lubricating structure of the rocker arm support of the horizontal four-cycle diesel of especially little cylinder diameter.
Background technique
In order to save maintenance cost, to have installed in the rocker arm support of, internal-combustion engine the same and be fixed with rocker arm bush with all fastness, rocking arm is installed on the corresponding axle of rocker arm support, and lining forms a fastness with axle.At this lining place, be still and be lubricated, and present lubricating system all is mist of oil and the splash lubrication that adopts.Because this place's operating temperature is higher, and the lubricants capacity at this place of the feasible arrival of this lubricating system is very limited again, so the lubricant oil at this place very easily is heated carbonization.Finally, form abrasive wear, shortened the normal working life of this lining on the contrary.And then cause valve timing inaccurate, and the engine starting difficulty, black smoke from exhaust, overall performance descends.
Summary of the invention
In order to overcome above-mentioned defective, the utility model proposes a kind of structure that changes existing lubricating system, to prolong the normal working life of described lining.
Realize the cooling and the lubricating structure of a kind of internal-combustion engine rocker arm support of the utility model purpose.Have spiral chute on the circumference of a supported end of internal combustion (IC) engine camshaft, on the supporting base corresponding the oil transportation hole is arranged with this supported end, there is a transport pipe to be connected on this oil transportation hole, this oil inlet hole is the oil transportation channel of UNICOM's cylinder head and rocker arm support, end has axle to be pitman arm shaft about rocker arm support, all have hole radially to communicate with the oilhole of rocker arm support on it, rocker arm bush is fixed on the rocking arm and forms fastness with pitman arm shaft.
Realize the cooling and the lubricating structure of the another kind of internal-combustion engine rocker arm support of the utility model purpose.Have spiral chute on the circumference of a supported end of internal combustion (IC) engine camshaft, on the supporting base corresponding the oil transportation hole is arranged with this supported end, there is a transport pipe to be connected on this oil transportation hole, the other end of this transport pipe is connected on the oil inlet hole on the rocker arm support, and this oil inlet hole is by an oil transportation channel and the interior rocker arm bush UNICOM of rocker arm support.
Spiral chute on the supported end circumference of described internal combustion (IC) engine camshaft can be that camshaft itself just has.As long as its rotation direction can guarantee: after this camshaft rotated, the effect that can form volute pump got final product.When camshaft rotated, this spiral chute just pumped the lubricant oil in the internal combustion (IC) engine airframe from the oil transportation hole of described supporting base, enter described transport pipe and oil transportation channel, arrives described rocker arm bush at last, so that the fastness that it was constituted is cooled off and lubricates; Also rocker arm support is cooled off simultaneously.Obviously, the matching gap of utilizing fastness itself to exist just can make the flow of lubricant that has lubricated lining and cooled off this lining and rocker arm support thereof simultaneously get back in the internal combustion (IC) engine airframe.
Superiority of the present utility model is as follows:
Compare with splash lubrication with existing mist of oil, what structure of the present utility model adopted is pressure lubrication.It not only guarantees to have the supply of sufficient lubricant oil when lubricated, the more important thing is lubricant oil endlessly can to rocker arm bush and rocker arm support thereof play cooling effect---its lubricant oil itself does not have yet and has been heated to the adverse consequences of carbonization.Naturally the prolongation that just obtain the working life of rocker arm bush.So can keep IC engine gas distribution accuracy regularly for prolonged period of time, engine starting is easy, exhaust is normal, and overall performance is stable.

Embodiment
Embodiment 1 (with reference to figure 1, Fig. 3):
A kind of cooling of internal-combustion engine rocker arm support 1 and lubricating structure.Have spiral chute on the circumference of a supported end of internal combustion (IC) engine camshaft 8, on the supporting base 7 corresponding the oil transportation hole is arranged with this supported end, there is a transport pipe 6 to be connected on this oil transportation hole, the other end of this transport pipe is connected on the oil inlet hole of cylinder head 5---and when described spiral fluted rotation direction is rotated with assurance camshaft 8, can make this spiral chute pump lubricant oil and be as the criterion to the oil transportation hole; The two ends of described transport pipe 6 have the copper packing 4 with 3 mating reactions of threeway bolt, the screw that described oil transportation hole and oil inlet hole have the screw thread with threeway bolt 3 to be complementary is connected to the two ends of this transport pipe 6 on oil transportation hole and the oil inlet hole with two threeway bolts 3.This oil inlet hole is UNICOM's cylinder head 5 and the oil transportation channel of rocker arm support 1, and a setting sleeve 2 as an oil transportation channel part is arranged betwixt---obviously, locate also with other public modes or structure and to be fine; End has axle to be pitman arm shaft about rocker arm support 1, all have hole 12 radially to communicate on it; rocker arm bush is fixed on the rocking arm with pitman arm shaft and forms fastness; lubricant oil has been finished lubricated and refrigerating function with oil transportation hole 11, from the gap natural back flow between rocker arm bush and pitman arm shaft in the body of internal-combustion engine.
Embodiment 2 (with reference to figure 2, Fig. 3):
