Description
Technical field
The utility model relates to a kind of chain saw, relates in particular to a kind of electric chain saw that is used to cut timber.
Background technology
Offer the electric chain saw that the carpenter uses in the market, its operation principle is that motor rotor is provided with gear with the power drives motor, thereby the driven gear that drives on the power transmission shaft by driving gear drives sprocket, sprocket drives saw chain, makes saw chain slide work at a high speed on guide rod.In work time, is untimely then oily because friction can produce a large amount of heats like this, is easy to damage owing to saw chain is overheated saw chain and guide rod.Generally also all 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, 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, make saw chain lack enough profit bones when in use, be subjected to big frictional force when causing saw chain on guide rod, to move work, make the guide rod heating, serious wear, thus guide rod and saw chain damaged, shorten the service life of electric chain saw.In addition, driving gear on the motor rotor head and the driven gear cooperating on 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 occurs at the flank of tooth and the inoperative position intersection of gear, the effect sideshake increases, the noise that produces is big, and vibration force increases, even causes transmission system entirely ineffective.
Summary of the invention
The purpose of this utility model be to provide a kind of can the lubricated electric 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 electric chain saw of the utility model, comprise saw chain, guide rod, motor, the driven gear that is connected with on the motor 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 full of lubricating oil in the gear-box.Can make driven gear and driving gear in the gear-box obtain lubricating fully like this, reduce frictional force surface abrasion between gear and minimizing energy loss.
Described gear-box inwall is provided with oil ga(u)ge.So just can clearly see the amount of the lubricating oil in the gear-box clearly.
Described gear-box is provided with pouring orifice and lid, can in time add lubricating oil according to actual conditions.
The power transmission shaft at described driven gear center is provided with oil guiding hole and oil guide pipe, and one or more oil outlets that this oil guide pipe and sprocket are provided with communicate.By oil guide pipe and oil outlet are set, make the interior lubricating oil of gear-box by oil guide pipe and oil outlet, lead on the sprocket through mechanical movement, contacting by sprocket and saw chain then, saw chain is lubricated, reduced when saw chain runs up on guide rod and the frictional force between guide rod, reduced wearing and tearing, the service life of having improved saw chain.
The inwall of oil guide pipe is provided with screw thread.Help Oil Guide so more.
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.
Described oil-guide device preferably adopts the oil tanker that is arranged on driven gear or the power transmission shaft; Perhaps by the oil pump Oil Guide is set.
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 electric chain saw lubricating oil when not working be unlikely to leak into the outside; when electric chain saw is worked; because of being subjected to the effect of torsion; flat spring is out of shape slightly and has broken away from oil guiding hole, makes lubricating oil can enter into oil guide pipe.
Described gear-box seals with sealing device.Preferred sealing ring or the sealing gasket of adopting seals.
The utility model has solved the defective that exists in the background technology, can make the various mechanisms in the electric 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 electric chain saw.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described further by specific embodiment.
A kind of electric 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, are full of lubricating oil in the gear-box 8, fuel tank as oil storage uses, and gear-box seals with sealing ring.The power transmission shaft 5 at driven gear 6 centers is provided with oil guiding hole 9 and oil guide pipe 15,3 oil outlets 10 that alternately distribute on the side of sprocket 7, and oil guide pipe 15 and oil outlet 10 communicate.On the driven gear 6, around oil guiding hole 9, be provided with an oil tanker 11, when machine works, lubricating oil can be directed in the oil guide pipe 15 by oil tanker 11, also be provided with flat spring on the oil guiding hole 9, one end of this flat spring is fixed on the power transmission shaft 5, the other end is just sealed oil guiding hole, when electric chain saw was not worked, flat spring was sealed oil guiding hole 9, can prevent leakage of oil, when electric chain saw is worked, because of being subjected to the effect of torsion, flat spring is out of shape slightly and has broken away from oil guiding hole 9, makes lubricating oil can enter into oil guide pipe 15.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.
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, because the effect of torsion, make the flat spring distortion break away from oil guiding hole, because the guiding of oil tanker, make lubricating oil can enter oil guiding hole, then through oil outlet on sprocket, by contacting of sprocket and saw chain, running by saw chain, take lubricating oil the contact-making surface of sprocket and guide rod to, realized self-lubricate, reduced the frictional force between saw chain and the guide rod saw chain, guide rod, reduce 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 any position that is included in the gear-box on the power transmission shaft.Auto-supply lubrication principle any and of the present utility model with structure all should be in protection domain described in the utility model.
