The transmission device is connected with the motor through a transmission shaft. The electric circular saw is characterized in that the transmission device comprises a planetary gear train and an output gear train, the planetary gear train is connected with the motor, and output gear train is connected with the saw blade. The electric circular saw is simple in structure, solves the problems in the prior art well, makes up the defects, and is worth popularizing.
Description
Technical field
The utility model relates to the constructing technology field of cutting electric instrument, refers to especially a kind of electric circular saw that increases torsion.
Background technology
Electric circular saw is to be applicable to cut the electric tool that the objects such as timber, plastics, fiberboard are used.On market, the existing common built-in transmission of hand-held class electric circular saw is the gear train of driving tooth and driven tooth composition, the number of teeth is smaller, cause output speed larger, on conventional spongiosa cut substrate, can operate, even and if because torsion does not reach, can cause cannot normal operating or also can only cut with very slow speed the larger rotating speed in the situation that when running into the thicker cut substrate of density, efficiency reduces greatly, and the scope of having chosen of cut substrate is limited, and this class electric circular saw easily damages.The problems referred to above need technological improvement to be solved.
Summary of the invention
The purpose of this utility model is to provide a kind of scope of application that increases, and increases long-life increase torsion electric circular saw.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of electric circular saw that increases torsion, comprise motor, support, baffle plate, fan, saw blade and transmission device, motor connects baffle plate, fan is arranged on internal stent, baffle plate is connected with support, and transmission device is connected with motor by power transmission shaft, it is characterized in that: described transmission device comprises epicyclic train and output gear train, wherein epicyclic train connecting motor, output gear train connects saw blade.
Further, described epicyclic train comprises one-level gear and secondary gear, and one-level gear engages with secondary gear internal tooth, and secondary gear connects output gear train.
Further, described output gear train comprises driving wheel and driven pulley, and driving wheel engages with driven pulley external tooth; Driven pulley connects saw blade.
Further, the diameter of described driving wheel is greater than the diameter of driven pulley.The rotating speed that driving wheel is less, can drive driven pulley running relatively at a high speed.
Further, described power transmission shaft afterbody is provided with retainer ring.Retainer ring, for fixing driving wheel, prevents because the excessive power transmission shaft that skids off of rotating speed.
When the utility model uses, epicyclic train outputs power, be transferred on the driving wheel of output gear train, become the secondary transmission that moment of torsion increases, and then transmit on driven pulley by driving wheel, the diameter of driving wheel is greater than the diameter of driven pulley, reaches the output speed of final requirement and the larger moment of torsion that rotatablely moves, can under the desired minimum cut rotating speed of cut substrate, torsion be become to maximum, greatly improve cutting efficiency.
Brief description of the drawings
Fig. 1 is that the utility model is implemented structural representation.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with drawings and Examples.
In conjunction with Fig. 1, the utility model relates to a kind of electric circular saw that increases torsion, comprise motor 1, support 2, baffle plate 3, fan 4, saw blade 5 and transmission device 6, motor 1 connects baffle plate 3, and fan 4 is arranged on support 2 inside, and 3, baffle plate is connected with support 2, transmission device 6 is connected with motor 1 by power transmission shaft 7, transmission device 6 comprises epicyclic train 61 and output gear train 62, and epicyclic train 61 comprises one-level gear 611 and secondary gear 612, and secondary gear 612 connects output gear train 62; Output gear train 62 comprises driving wheel 621 and driven pulley 622, and driven pulley 622 connects saw blade, and the diameter of driving wheel 621 is greater than the diameter of driven pulley 622; The afterbody of power transmission shaft 7 is provided with retainer ring 71, and retainer ring 71 can prevent driving wheel 621 power transmission shaft 7 that slides out because running up.In the utility model operating process, epicyclic train 61 outputs power, be transferred on the driving wheel 621 of output gear train 62, become the secondary transmission that moment of torsion increases, and then transmit on driven pulley by driving wheel, the diameter of driving wheel 621 is greater than the diameter of driven pulley 622, thereby reaches the output speed of final requirement and the larger moment of torsion that rotatablely moves, can under the desired minimum cut rotating speed of cut substrate, torsion be become to maximum, greatly improve cutting efficiency.The utility model is simple in structure, but can solve the problem of prior art, supplies a gap, and is worthy to be popularized.
