Description
Technical field
The present invention relates to a kind of driving mechanism of electric tool, particularly relate to a kind of driving mechanism that can effectively reduce electric tool width.
Background technique
In field of power tools, a lot of place needs the driving mechanism used based on gear, such as chain saw, need to use the output speed of a series of driving mechanism to motor to slow down, but carry out speed change because driving mechanism often have employed multiple gear, volume is very huge, and the instrument that this needs of chain saw are hand-held, its size, build needs to consider the factors such as ergonomics, wherein the most important point be exactly electric tool along motor drive shaft to width can not be large, otherwise the volume of shell both can have been made to become very large, instrument is made to become very too fat to move, also have influence on the vanning of user to the gripping comfort level of instrument and instrument to transport simultaneously.In prior art, still for chain saw, the motor of chain saw and working head are all provided at the both sides of driving mechanism, so just make the width of chain saw greatly increase, bring inconvenience to user.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of driving mechanism of electric tool, there is shell, be located at the motor in described shell, the gear be connected with the rotating shaft transmission of described motor, the output shaft be in transmission connection with described gear, the shaft axis of described machine shaft and the axis parallel of described output shaft, it is characterized in that: described motor and described output shaft are positioned at the same side of described gear, described gear at least comprises the first gear engaged successively, second gear and the 3rd gear, described first gear, the shaft axis of the second gear and the 3rd gear all with the axis parallel of described machine shaft, described first gear is connected with the rotating shaft transmission of described motor.
Preferably, the shaft axis of described first gear, the second gear and the 3rd gear is coplanar.
Preferably, described gear also comprises transmission shaft, the 4th gear, internal tooth torus, one end of described transmission shaft is connected with described 3rd gear transmission, its the other end is connected with described 4th gear transmission, described 4th gear and described internal tooth torus internal messing, described internal tooth torus and described output shaft are in transmission connection.
Further preferably, described driving mechanism is also fixed with oiling device, described oiling device engages with described internal tooth torus and can to this engagement place lube oil injection.
Preferably, described electric tool is chain saw.
Preferably, described electric tool is pruning shears.
Compared to prior art, driving mechanism of the present invention, by the arrangement again to transmission part, efficiently reduces the width of electric tool, the outer casing space of instrument is reduced, has widened Gear center distance simultaneously, improve transmission efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is the front sectional view of driving mechanism of the present invention;
Accompanying drawing 2 is the vertical view cutaway drawing of driving mechanism of the present invention.
In accompanying drawing:
1-shell, 2-motor, 3-gear, 4-output shaft, 5-oiling device;
31-first gear, 32-second gear, 33-the 3rd gear, 34-transmission shaft, 35-the 4th gear, 36-internal tooth torus.
Embodiment
Below in conjunction with accompanying drawing being preferred embodiment described in detail to driving mechanism of the present invention.
See accompanying drawing 1-2, driving mechanism of the present invention comprises shell 1, is provided with motor 2 in shell 1, and rotating shaft and a gear 3 of motor 2 are in transmission connection, and the rotating speed eventually passing through speed change is exported by an output shaft 4 by gear 3; In overall distribution, output shaft 4 and motor 2 are all positioned at the same side of gear 3, and effectively reduce the width of whole mechanism like this, make the parts in shell 1 compacter, the space availability ratio of shell 1 is improved.
In the present embodiment, the main body of gear 3 is a gear-box, the first gear 31 is provided with in gear-box, second gear 32 and the 3rd gear 33, above-mentioned three gears engage successively, wherein the first gear 32 is for input speed, the output shaft of itself and motor 2 is in transmission connection, 3rd gear 33 is for exporting the rotating speed of this one-level, directly it can be connected with output shaft 4 output carrying out rotating speed, also can be as shown in drawings, increase one-level speed change again, one end of 3rd gear 33 and a transmission shaft 34 is in transmission connection, the other end and the 4th gear 35 of this transmission shaft 34 are in transmission connection, 4th gear 35 is small gear, it is the relation of internal messing between itself and internal tooth torus 36.The engagement system of this internal gear-internal tooth torus greatly can reduce output speed, and internal tooth torus 36 connects output shaft 4, and final output one meets the rotating speed of operating mode.Preferably, internal tooth torus 36 is provided with an oiling device 5, this oiling device 5 is fixed relative to shell 1, engages, to engagement place lube oil injection, can effectively ensure that the normal operation of mechanism with internal tooth torus 36.
All the time the principle reducing volume is as far as possible have followed in the component arrangement of the present embodiment, also namely motor 2 and output shaft 4 are arranged on the homonymy of gear 3, in order to reserve enough arrangement spaces at homonymy, as further preferred embodiment, the shaft axis distance of the first gear 31, second gear 32 and the 3rd gear 33 is widened, except ensureing the axis parallel of three, also they are arranged in same plane, so not only add the space of homonymy arrangement, motor 2 can more reasonably arrange nigh position simultaneously, makes transmission efficiency higher.
Compared to prior art, driving mechanism of the present invention had both reduced taking up room of transmission part, and make overall structure compacter, cross section is little, simultaneously more reasonably to the arrangement position of motor and transmission part, made transmission efficiency higher.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
