Abstract
The utility model discloses an electric chain saw, comprising a motor, a motor shaft, an output shaft, a cutting element, a bull gear, a pinion and a sprocket, wherein one end of the motor shaft is arranged in the motor, the other end of the motor shaft is fixed with the pinion, the bull gear is meshed with the pinion, the sprocket and the bull gear are arranged together, the cutting element and the sprocket are arranged together, the bull gear drives the sprocket to rotate, so as to drive the cutting element to rotate, and the output shaft is arranged in the sprocket and is fixed steadily. The electric chain saw has the advantages that the structural design is simple, the overall size is reduced and the like.
Description
Technical field:
The utility model relates to a kind of power tool, particularly relates to a kind of electric chain saw.
Background technology:
At present, electric chain saw on market mainly comprises motor, motor shaft, output shaft, cutting element, gear wheel and pinion, wherein, motor shaft one end is arranged in motor, the other end and pinion are fixed, output shaft one end is fixed in gear wheel, the other end and cutting element are set together, gear wheel and pinion are meshed, motor shaft drives pinion rotation, meshes by gear and drives the gear wheel rotation, and gear wheel drives output shaft rotation, output shaft drives cutting element again and rotates, and realizes the work purpose.The shortcoming of this structure is: output shaft must rotate could realize the work purpose, this has long enough with regard to the length that requires output shaft, the length increase of output shaft will certainly increase the volume of whole electric chain saw, has increased simultaneously the volume of packing and has increased production cost.Therefore, be necessary to be improved.
The utility model content:
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of reasonable in design is provided and can reduces the electric chain saw of overall volume.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of electric chain saw, comprise motor, motor shaft, output shaft, cutting element, gear wheel and pinion, wherein, motor shaft one end is arranged in motor, and the other end and pinion are fixed, gear wheel and pinion are meshed, also comprise sprocket wheel, described sprocket wheel and described gear wheel are set together, and described cutting element and described sprocket wheel are set together, described gear wheel drives described sprocket rotation and then drives described cutting element rotation, and described output shaft is arranged in described sprocket wheel and maintains static.
Be provided with torsion spring between described sprocket wheel and described gear wheel.
Be provided with four needle bearings between described sprocket wheel and described output shaft.
The utility model has following advantage with respect to prior art:
The utility model design output shaft is motionless, sprocket wheel and gear wheel are set together, cutting element and sprocket wheel are set together, gear wheel drives sprocket rotation and then drives the cutting element rotation, realize the work purpose, output shaft does not rotate the volume that can effectively reduce whole electric chain saw, has reduced simultaneously the volume of packing and has reduced production cost.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
referring to Fig. 1, a kind of electric chain saw that provides according to the utility model, comprise motor 1, motor shaft 2, output shaft 3, cutting element 4, gear wheel 5 and pinion 6, wherein, motor shaft 2 one ends are arranged in motor 1, the other end and pinion 6 are fixing, gear wheel 5 and pinion 6 are meshed, also comprise sprocket wheel 7, this sprocket wheel 7 is set together with gear wheel 5, cutting element 4 is set together with sprocket wheel 7, gear wheel 5 band movable sprockets 7 rotate and then drive cutting element 4 rotations, output shaft 3 is arranged in sprocket wheel 7 and maintains static, design output shaft 3 is motionless, sprocket wheel 7 and gear wheel 5 are set together, cutting element 4 is set together with sprocket wheel 7, gear wheel 5 band movable sprockets 7 rotate and then drive cutting element 4 rotations, realize the work purpose, output shaft 3 does not rotate the volume that can effectively reduce whole electric chain saw, reduced simultaneously the volume of packing and reduced production cost.
Be provided with torsion spring 8 between sprocket wheel 7 and gear wheel 5, be provided with four needle bearings 9 between sprocket wheel 7 and output shaft 3.
Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that do not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
