Abstract

The utility model relates to an electric roller brush without driving force. The roller brush takes the mode of dual parallel array, and obtains dual torsion with equal size and opposite rotating directions from a conical gear type differential device of a driving device through symmetrical flexible shafts; the purpose of eliminating driving effect is realized. Using the brush, operators are not easy to fatigue; simultaneously, a motor of the device is free from the limit of size, and is capable of satisfying working requirements under various difference occasions and conditions.

Description

The electronic roller brush of non driving force

The utility model be about electronic roller brush in invention.

The Electric brush that uses is simple in structure at present, normally presses a brush wheel on small hand-held formula motor.Operator's handheld electrical machinery handle is connected power supply brush wheel is got into smooth, and allows brush wheel go to the contactant surface to carry out work then.This Electric brush exists two big shortcomings: one, the brush wheel that runs up has produced very strong trend motive force by the reaction of body surface.Roll forward for brush wheel is not kept here, the operator must pay very big muscle power and remove to resist this trend motive force, and labour intensity is big, is easy to fatigue; Its two because motor is hand-held, the power that this has limited motor undoubtedly again makes operating efficiency can not improve.

The purpose of this utility model provides a kind of Electric brush, it when work to operator's effect of not tending to act, the big I of motor is not limited by miniaturization as required and calmly simultaneously.

The utility model is achieved in that the equal principle of left and right half gear output torque of utilizing conical gear formula differential mechanism, be provided with symmetrical output bevel gear respectively with this left and right half conical gear interlock, use to arrange the moment of torsion that two parallel output shafts are externally exported the equal and opposite in direction switched in opposite.Again with two symmetrical flexible axles the brush wheel of two groups of axially parallels or polishing wheel and two corresponding coupling together of output shaft, the moment of torsion that is obtained on such two groups of brush wheels or the polishing wheel is equal and opposite in direction switched in opposite all the time just.So the moment of torsion of two-wheeled is just cancelled each other when working, externally do not produce the effect of tending to act on body surface.

The utility model is because the starting point is to eliminate the trend motive force of brush wheel or polishing wheel, adopt the method for flexible axle transmission simultaneously, so it not only makes the operator feel laborsaving light, and the work drive motor size is unrestricted, be equipped with corresponding brush wheel or polishing wheel, can satisfy the need of work of various different occasions and condition.

The embodiment and the description of drawings thereof of the concrete structure of utility model are as follows:

Fig. 1 is the transmission mechanism schematic diagram of wooden utility model.

Fig. 2 is an assembling schematic diagram of the present utility model.

The moment of torsion that belt pulley (1) transmits is passed to planetary conical cone gear (3) through cross axle (2), divides left half axle conical gear (4) and the right axle shaft Knucle-gear (5) of passing to both sides again.Conical gear (4) and (5) are special symmetrical double cog conical gears.The as many as bascule of the power transmission situation of planetary conical cone gear (3), no matter planetary conical cone gear (3) revolves round the sun or rotation, it always gives the moment of torsion mean allocation left and right two-semiaxle conical gear (4) and (5), and (in fact the rub-moment between the part and two flexible axle loss moments are all very little, and are very little to the torque distribution influence.) left and right two-semiaxle conical gear (4) and (5) output bevel gear (6) and (7) interlock of symmetry together respectively again, and make two output shafts (6 ') opposite with (7 ') axis parallel steer.Be installed in for this transmission system to have in the special-purpose casing (8) of fixing footing.Casing (8) is fixed on above the tripod steamboat flat car (10) with motor (9) and connects.Two groups of symmetry brush wheel or polishing wheels (11) and (12) are installed in the bearing support (13) abreast.Control stick (14) can rotate around the supporting lead screw on the bearing support (13).Respectively output shaft (6 ') and (7 ') are coupled together with brush wheel or polishing wheel (11) and (12) correspondence with the power-type flexible axle (15) of two symmetries and (16), whole like this device has just been formed.

Claims

1, the electronic roller brush of a kind of non driving force, by tripod steamboat flat car (10), motor (9), conical gear formula differential mechanism transmission device, symmetry flexible axle (15) and (16), be connected between the brush wheel support (13) and form, it is characterized in that: the power that motor (9) sends is passed to conical gear formula differential mechanism, the output shaft of parallel symmetry (6 ') and (7 ') are from this differential left, the antithesis moment of torsion that obtains the equal and opposite in direction switched in opposite is gone up in right axle shaft conical gear (4) and (5), this antithesis moment of torsion has realized eliminating the purpose of the effect of tending to act by symmetrical flexible axle (15) and (16) the two groups of parallel brush wheels that go to tend to act.

2, conical gear formula differential mechanism transmission device according to claim 1, the axle (2) that it is characterized in that this differential mechanism is the quadrature cross structure, left and right half conical gear (4) and (5) are symmetrical double cog conical gears, and left and right output shaft (6 ') is symmetry and parallel with (7 ').
