Description
Technical field
The utility model relates to a kind of chain saw, relates in particular to a kind of chain saw that is used to cut timber.
Background technology
Offer the chain saw that the carpenter uses in the market, its operation principle is to drive driving gear with power set (comprising gasoline engine and motor), thereby the driven gear that drives on the power transmission shaft by driving gear drives sprocket, and 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 fuel loading system on the present electric 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, driven gear cooperating on driving gear and the power transmission shaft, produce friction in the time of work, now mainly be to rely on the lubricant of application when dispatching from the factory to be lubricated, in prolongation along with service time, the loss of lubricant, the decline of lubricant quality, lubricant effect descends even loses lubrication, is easy to cause flank of tooth fret wear like this, step appears in the flank of tooth and inoperative position intersection at gear, the effect sideshake increases, and the noise of generation is big, and vibration force increases, even cause transmission system entirely ineffective, reduced the use of chain saw and received a mandate.
Summary of the invention
The purpose of this utility model be to provide a kind of can the lubricated chain saw of auto-supply.
In order to overcome the defective that exists in the background technology, the utility model provides following technical scheme according to the lubricating requirement and the operating mode working environment thereof of each mechanism's friction requirements in the plant equipment master-plan:
A kind of chain saw of the utility model, comprise saw chain, guide rod, power set, the driven gear that is connected with on the power set on driving gear and the power transmission shaft is connected, driven gear drives the sprocket that is connected with saw chain, thereby driving saw chain moves on guide rod, described driving gear and driven gear are arranged in the sealed gear case, are filled with lubricating oil in the gear-box.Can make driven gear and driving gear in the gear-box obtain lubricating fully like this, lubricating oil comes out from oil guiding hole, makes guide rod and saw chain obtain sufficient lubrication, reduces frictional force to surface abrasion between gear and minimizing energy loss.
Can also in gear-box, be provided with the fuel tank that is filled with lubricating oil as of the present utility model, reach same effect.
Be provided with oil-guide device in the described gear-box.Can make being seeped on the sprocket that lubricating oil in the gear-box is more prone to like this, saw chain and guide rod are lubricated.
As of the present utility model preferred, described oil-guide device is to be provided with oil guiding hole on gearbox wall, described oil guiding hole preferably is arranged on above the saw chain and on the face parallel with saw chain, and in the chain saw running, lubricating oil comes out saw chain and guide rod are played lubrication from oil guiding hole.
Described oil-guide device is provided with shuts down the stopping leak device.Described shutdown stopping leak device preferably adopts flat spring; the effect that flat spring can play the sealing oil guiding hole is set; make chain saw lubricating oil when not working be unlikely to leak into the outside; when chain saw is worked; rotation because of gear; lubricating oil in the fuel tank is flowed, and flat spring is out of shape slightly and has broken away from oil guiding hole, makes lubricating oil can enter into oil guiding hole.
Be provided with oil ga(u)ge in the described fuel tank.The amount that can clearly show lubricating oil in the fuel tank like this.
Be provided with dust guard outside oil guiding hole, this dust guard preferably adopts the mesh dust cover, is used for preventing that foreign material such as wood chip from entering oil guiding hole and stopping up oil guiding hole.
Described gear-box or fuel tank seal with sealing device, preferably adopt sealing ring or sealing gasket, to prevent oil leakage phenomenon.
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.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described further by specific embodiment.
A kind of chain saw of present embodiment, comprise saw chain 1, guide rod 2, motor 3, the driven gear 6 that 3 in motor is provided with on driving gear 4 and the power transmission shaft 5 is connected, driven gear 6 drives the sprocket 7 that is connected with saw chain 1, move on guide rod 2 thereby drive saw chain 1, described driving gear 4 and driven gear 6 are arranged in the sealed gear case 8, fill lubricating oil in the gear-box 8, fuel tank as oil storage uses, and gear-box seals with sealing ring.Gear-box is provided with oil guiding hole 9.When machine works, lubricating oil is directed in the oil guiding hole 9 under the pressure that gear operation produces, and oozes then to guide rod 2 and saw chain 1, and guide rod 2 and saw chain 1 are played lubrication.Also be provided with flat spring 11 on the oil guiding hole 9 and seal oil guiding hole, this fixedly other end perk of flat spring 11 1 ends is easier to break away from oil guiding hole like this when chain saw is worked, and makes oil be easy to ooze out.When electric chain saw was not worked, flat spring was sealed oil guiding hole 9, can prevent leakage of oil, and when electric chain saw was worked, flat spring 11 was out of shape slightly and has broken away from oil guiding hole 9, makes lubricating oil can enter into oil guiding hole 9.Also be provided with oil ga(u)ge 12 in the gear-box 8, can reflect the amount of oil in the gear-box timely.Also be provided with oil filler 13 and seal closure 14 on the gear-box.Also be provided with mesh dust cover 10 on the oil guiding hole 9, prevent that foreign material such as wood chip from entering oil guiding hole 9 and stopping up oil guiding hole 9.
Because gear-box 8 is full of lubricating oil for what seal in gear-box 8 inside, can make the parts of gear-box 8 inside obtain sufficient lubrication.When electric chain saw is started working, momentum effect at the lubricating oil that flows, make the flat spring distortion break away from oil guiding hole, lubricating oil can enter oil guiding hole, then through infiltrating on the guide rod, by contacting of guide rod and sprocket and saw chain, running by saw chain, lubricating oil is taken to the contact-making surface of sprocket and guide rod, realized self-lubricate to saw chain, guide rod, reduce the frictional force between saw chain and the guide rod, reduced the wearing and tearing between saw chain and guide rod, improved the service life and the service behaviour of electric chain saw.
In addition, the oil guiding hole in the present embodiment can be arranged on any position in the fuel tank.The similar structure of auto-supply lubrication principle any and of the present utility model all should be in protection domain described in the utility model.
Embodiment 2: present embodiment medium power device adopts gasoline engine; fuel tank 15 is set in gear-box; fill lubricating oil in the fuel tank 15; have oil guiding hole 9 on the fuel tank 15; oil guiding hole 9 is provided with shuts down antidiarrheal device flat spring 11; be covered with mesh dust cover 10 in the oil guiding hole outside, other structure is identical with embodiment 1.
