Abstract
The utility model relates to an electric reciprocating saw and pertains to the technical field of electric tools. The reciprocating saw comprises a housing internally provided with a motor. An output shaft of the motor drives an eccentric wheel which is coaxially arranged with a driven bevel gear via a reducing mechanism. The eccentric wheel is in transmission connection with a saw blade capable of performing reciprocating motion via a slider crank mechanism. The electric reciprocating saw is improved in that the reducing mechanism comprises a driving gear which is coaxially arranged with the output shaft of the motor; the driving gear is engaged with an internal gear arranged in the housing and coaxially arranged with a small bevel gear; and the small bevel gear is engaged with the driven bevel gear. The electric reciprocating saw is compact in structure, small in size and more convenient in application and usage and is smoothly held.
Description
Technical field
The utility model relates to a kind of cutting tools, and especially a kind of electric reciprocating saw, belongs to electric tool technical field.
Background technology
Electric reciprocating saw is a kind of conventional cutting tools, the Chinese patent application document that its basic structure can be 201210587930.2 referring to application number, the motor of installing in its housing drives the eccentric wheel coaxial with passive bevel gear by reduction gear of bevel gear structure, this eccentric wheel drives the saw blade being fixedly connected with slide block to do and the reciprocating motion of motor axially parallel by slider-crank mechanism, thereby realizes required sawing.
According to the applicant understood, existing electric reciprocating saw is due to limited and bevel gear reduction gearing mechanism, and therefore the distance between the reciprocating motion track of motor shaft and saw blade is larger; In addition, in order to meet the requirement of speed reducing ratio, the diameter of passive bevel gear is larger, and the space therefore occupying is larger, thereby makes current reciprocating saw structure not compact, and it is comparatively heavy that width or length direction all seem, makes troubles to gripping and operation.
Summary of the invention
The purpose of this utility model is: the shortcoming existing for above-mentioned prior art, by the improvement to reducing gear, the electric reciprocating saw that a kind of compact conformation, volume obviously dwindle is proposed, and bring convenience thereby use to operation.
In order to reach above object, electric reciprocating saw of the present utility model comprises the housing of inner mounted motor, the output shaft of described motor drives the eccentric wheel coaxial with driven bevel pinion by reducing gear, described eccentric wheel is in transmission connection by slider-crank mechanism and reciprocating saw blade, its improvement is: described reducing gear contains the driving gear coaxial with motor output shaft, described driving gear be arranged on housing in and the internal gear coaxial with cone pinion engage, described cone pinion engages with driven bevel pinion.
Engage as first order reducing gear because the utility model has adopted inside and outside gear, therefore can obviously dwindle the distance between motor shaft and saw blade reciprocating motion track, reduce the size of complete machine width; Meanwhile, because bevel gear engagement is only as the second level reducing gear after the first order, therefore, in the situation that keeping required speed reducing ratio, the diameter of driven bevel pinion can obviously reduce, thereby has also shortened the size of complete machine length direction.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the B-B profile of Fig. 1.
Detailed description of the invention
Embodiment mono-
The electric reciprocating saw basic structure of the present embodiment as shown in Figure 1, 2, 3, the motor 3 that power brick 2 is powered is installed at the middle part of housing 1, output shaft 3-1 and the driving gear 4 of this motor are coaxially connected, driving gear 4 engages with the internal gear 5 being arranged in housing, and this internal gear 5 is coaxially connected by power transmission shaft 7 with cone pinion 6.Between internal gear 5 and cone pinion 6 and power transmission shaft 7 be supported on respectively bearing 1-1 and 1-2 from the external part of cone pinion 6.Cone pinion 6 engages with driven bevel pinion 8, driven bevel pinion 8 is coaxially connected with eccentric wheel 9, eccentric block 10 on eccentric wheel 9 is connected by chuck 10-1 and saw blade axis 11, form slider-crank mechanism, thereby under motor 2 drives, after double reduction, drive the saw blade 12 being connected with saw blade axis 11 to do required reciprocating motion.
Because the distance between motor shaft and saw blade axis is obviously dwindled in the inside and outside gear engagement that the reciprocating saw of the present embodiment adopts, double reduction transmission simultaneously is significantly dwindled the diameter of driven bevel pinion, therefore the size of complete machine width, length and thickness (referring to Fig. 2) direction is all reduced, whole electric reciprocating saw compact conformation, volume is small and exquisite, grip smoothly, operation is used more convenient.
