Background technology
Offer the chain saw that the user uses in the market, its operation principle is to drive transmission mechanism with power set (comprising gasoline engine and motor), thereby drive sprocket by power transmission shaft on the transmission mechanism, sprocket drives saw chain, makes saw chain slide work at a high speed on guide rod.Work time like this,,, be easy to damage saw chain and guide rod owing to saw chain is overheated if untimely oily because friction can produce a large amount of heats.Also be provided with fueller on the present chain saw, but will be by manually pushing the lubricator button at regular time and quantity or manually adding lubricating oil.In practical operation, workman's operation element situation complexity, often do not reach former design code by pressure request, comprise that number of times of pushing and the blanking time of pushing do not reach requirement, and in use foreign material such as wood chip stop up oil outlet easily and cause the oil pump capacity deficiency, it is enough lubricated that saw chain is lacked when in use, be subjected to big frictional force when causing saw chain on guide rod, to move work, make guide rod heating, serious wear, thereby damage guide rod and saw chain, shorten the service life of electric chain saw.In addition, producing friction in the time of transmission mechanism work, now mainly is to rely on the lubricant of application when dispatching from the factory to be lubricated, in the prolongation along with service time, the loss of lubricant, the decline of lubricant quality, lubricant effect descends even loses lubrication, is easy to cause the transmission mechanism wearing and tearing like this, the noise that produces is big, vibration force increases, even causes transmission mechanism entirely ineffective, has reduced the use of chain saw and has received a mandate.
The utility model content
The technical problems to be solved in the utility model is: a kind of chain saw that can auto-supply is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of chain saw, comprise housing, be contained in the transmission mechanism in the described housing, be connected saw chain with described transmission mechanism, also include fueller in the described housing, described fueller comprises oil pump, and also be provided with the fuel tank of oil-feed pump fuel feeding in the housing, also be provided with cam in the housing with the transmission mechanism interlock, oil pump is provided with plunger, and this oil pump is inconsistent by this plunger and cam.
According to another embodiment of the present utility model, chain saw comprises that further described transmission mechanism and cam are coaxial.
According to another embodiment of the present utility model, chain saw comprises further and also is provided with flexible member on the described oil pump that this flexible member provides restoring force for described plunger.
According to another embodiment of the present utility model, chain saw further comprises described camshaft line and described oil pump axis normal.
According to another embodiment of the present utility model, chain saw comprises that further described oil pump is equipped with check valve.
According to another embodiment of the present utility model, chain saw comprises that further described fuel tank or oil pump adopt the sealing device sealing.
According to another embodiment of the present utility model, chain saw further comprises in the described fuel tank and is provided with oil ga(u)ge.
The utility model has solved the defective that exists in the background technology, can make the various mechanisms in the chain saw obtain sufficient lubrication, has realized auto-supply, and can in time add lubricating oil according to actual needs, has improved the service life and the service behaviour of chain saw.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation (demonstration saw chain) of embodiment of the present utility model.
Fig. 2 is that the structural representation of embodiment of the present utility model (does not show saw chain.)
Fig. 3 is the part perspective view of embodiment of the present utility model.
Wherein: 2, housing, 4, transmission mechanism, 6, saw chain, 8, oil pump, 10, fuel tank, 12, cam, 14, plunger, 16, flexible member, 18, motor, 20, connecting rod, 22, power transmission shaft, 24, sprocket, X, cam (12) axis, Y, oil pump axis.
Embodiment
As shown in Figure 1, this figure is the structural representation with chain saw of the utility model feature.Though the present invention describes with reference to the one exemplary embodiment shown in the accompanying drawing, should be appreciated that the present invention can implement in the embodiment of many replacement forms.In addition, can use the parts or the material of any suitable size, shape or type.
Shown in Fig. 1-2, chain saw comprises housing 2, is contained in the described motor of seeing in the housing 2 18, and transmission mechanism 4 is connected saw chain 6 with described transmission mechanism 4, the connecting rod 20 that links to each other with housing 2, and this motor 18, transmission mechanism 4 are wholely set in housing 2 with saw chain 6.Connecting rod 20 is telescopic connecting rods.
As shown in Figure 3, chain saw in use, saw chain 6 is made high speed rotating with the speed of about 12 meters of per seconds round carrier bar.Under the situation of high speed high load capacity, saw chain 6 fricative temperature can continue to rise, and ruptured by the stuck or chain of the influence expansion of high temperature up to chain and carrier bar.Because chain, the damage of carrier bar will cause transmission mechanism 4, related damages such as motor 18.So saw chain must be used oil lubrication.So, in the housing 2 of chain saw, be provided with fueller, this fueller comprises oil pump 8, and also be provided with the fuel tank 10 of oil-feed pump 8 fuel feeding in the housing 2, also be provided with the cam 12 with transmission mechanism 4 interlocks in the housing 2, oil pump 8 is provided with plunger 14, and this oil pump 8 is inconsistent with cam 12 by this plunger 14, the plunger 14 that drives oil pump 8 that rotatablely moves by cam 12 moves reciprocatingly, and gives saw chain 6 fuel feeding.Also be provided with flexible member 16 on the oil pump 8, the restoring force that provides of plunger 14 is provided this flexible member 16, and preferably this flexible member 16 adopts spring.
In addition, can continue fuel feeding for making oil pump 8, the utility model preferably adopts the axis X of above-mentioned cam 12 installation method vertical with the axis Y of oil pump 8, and like this, as long as cam 12 rotates, oil pump 8 just can carry out fuel feeding to saw chain 6 automatically.
When starting chain saw, motor 18 drive transmission devices 4 at first, on the one hand, transmission mechanism 4 drives sprocket 24 and rotates, thereby drives saw chain 6 motions, and then cutting timber; On the other hand, transmission mechanism 4 drives cam 12 and rotates, and cam 12 promotes plunger 14 motions of oil pump 8, thereby the lubricating oil in the fuel tank 10 is flow on the saw chain 6 of motion through oil pump 8, plays lubrication.
Its transmission mechanism 4 adopts the arc Bevel Gear Transmission in the preferred embodiment of the present utility model.In order to make machine can allow operator's operation more freely in actual use, we change common internal gear transmission mechanism into the arc Bevel Gear Transmission.Adopt the arc Bevel Gear Transmission can effectively dwindle the weight and the volume of head section, can effectively improve gear-driven intensity and life-span simultaneously.Make more freely light that the operator becomes in actual use.
Should be appreciated that foregoing description only is in order to set forth the present invention.Those skilled in the art can make multiple replacement form and modification without departing from the invention.Therefore, the invention is intended to all these replacement forms, modification and modification is included in the protection domain of appended claims.
