Description

Driven shearing motor

Technical field

The present invention relates to a kind of motor configuration, particularly relate to a kind of driven shearing motor that is applied to driven shearing.

Background technology

As shown in Figure 1, existing driven shearing motor 100 mainly comprises one and is arranged at the magnet ring 11 in this holder 10 for the holder 10, one that are fixed on a driven shearing housing 90, and one by this holder 10 coated and this magnet ring 11 around rotor 12, this rotor 12 has a linking part 121 that protrudes this holder 10, this linking part 121 is for linking an eccentric wheel 91, this this eccentric wheel 91 of rotor 12 interlocks can drive blade 92 reciprocating motions while rotation, so that the result of use of cutting off hair to be provided.

But this driven shearing motor 100 has following shortcoming:

1. the arm of force length that this rotor 12 radially extends from an axle 122 can be limited to the structure of this magnet ring 11 and this holder 10, because arm of force length is restricted, so the torsion while rotation is still less.

2. this rotor 12 is to rotate in the confined space being coated at this holder 10, owing to being difficult for heat radiation, so can reduce the useful life of this driven shearing motor 100.

3. it is large that the winding 123 configuring on this rotor 12 takies volume, and the materials'use amount that causes winding the line is more, and manufacturing cost is high.

Summary of the invention

The object of the present invention is to provide one can promote torsion, good heat dissipation effect, and the lower driven shearing motor of manufacturing cost.

Driven shearing motor of the present invention comprises a holder, a rotor unit, and two bearings; This holder comprise one along an Axis Extension and around surrounding wall, fixation wall of radially extending from this surrounding wall, one be formed in this surrounding wall and along the arbor hole of this Axis Extension, and a winding that is sheathed on the outer peripheral face of this surrounding wall along this axis, this winding and this fixation wall are along this axis direction arranged spaced; This rotor unit comprises that one passes the axle of this arbor hole, a magnet ring around this winding along this axis, and an arm of force that is radially connected to this magnet ring from this axle; Described bearing be arranged at respectively the two ends of this surrounding wall and be connected in this surrounding wall and this axle between.

Driven shearing motor of the present invention, the fixation wall of this holder is near wherein one end of this surrounding wall, and the axle of this rotor unit has a linking part, and this linking part protrudes from this surrounding wall one end near this fixation wall.

Driven shearing motor of the present invention, the fixation wall of this holder is near wherein one end of this surrounding wall, and the axle of this rotor unit has a linking part, and this linking part protrudes from the other end of this surrounding wall.

Beneficial effect of the present invention is: because this winding and this fixation wall are along this axis direction arranged spaced, the configuration of this magnet ring can not be subject to the structural limitations of this fixation wall, so the length of this arm of force is can more existing design long, when this rotor unit running, just can produces larger torsion and export; And because this winding is not coated completely, and this rotor unit can produce air-flow while rotating, so this driven shearing motor possesses the advantage of good heat dissipation effect; In addition, the small volume that this winding is shared, so coiling materials'use amount is lower, so can reach effect that manufacturing cost is lower.

Brief description of the drawings

Fig. 1 is a schematic diagram, and the structure of existing driven shearing motor is described;

Fig. 2 is a schematic diagram, and one first preferred embodiment of driven shearing motor of the present invention is described;

Fig. 3 is a schematic diagram, and one second preferred embodiment of driven shearing motor of the present invention is described.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in detail.

As shown in Figure 2, the first preferred embodiment of driven shearing motor 200 of the present invention comprises a holder 20, a rotor unit 30, and two bearings 40.

This holder 20 is for being fixed on a driven shearing housing 90, and comprise one along an axis X extend and around surrounding wall 21, fixation wall of radially extending from this surrounding wall 21 22, one be formed in this surrounding wall 21 and along the arbor hole 23 of this axis X extension, an and winding 24 that is sheathed on the outer peripheral face of this surrounding wall 21 along this axis X.

This fixation wall 22 is close to wherein one end of this surrounding wall 21, the holder width W 1 that this fixation wall 22 radially formed is greater than the rotor width W2 that this rotor unit 30 radially formed, so be unlikely the medial surface that touches this driven shearing housing 90 when this rotor unit 30 rotates.

This winding 24 is along this axis X direction arranged spaced with this fixation wall 22.

This rotor unit 30 comprises that one passes the axle 31 of this arbor hole 23, a magnet ring 32 around this winding 24 along this axis X, and an arm of force 33 that is radially connected to this magnet ring 32 from this axle 31.

This axle 31 has a linking part 311, and in the present embodiment, this linking part 311 protrudes from this surrounding wall 21 and be close to one end of this fixation wall 22.

This linking part 311 is for linking an eccentric wheel 91, and this this eccentric wheel 91 of rotor unit 30 interlocks can drive blade 92 reciprocating motions while rotation, so that the result of use of cutting off hair to be provided.

Described bearing 40 is arranged at respectively the two ends of this surrounding wall 21 and is connected between this surrounding wall 21 and this axle 31.

As shown in Figure 3, the second preferred embodiment of the present invention is similar to this first preferred embodiment, and its difference part is, this connecting portion 311 also can protrude from the other end of this surrounding wall 21, is away from one end of this fixation wall 22.

Whereby, because this winding 24 is along this axis X direction arranged spaced with this fixation wall 22, the configuration of this magnet ring 32 can not be subject to the structural limitations of this fixation wall 22, so the length of this arm of force 33 is can more existing design long, when turning round, this rotor unit 30 just can produce larger torsion output, then, because this winding 24 is not coated completely, and this rotor unit 30 can produce air-flow while rotation, so this driven shearing motor 200 possesses the advantage of good heat dissipation effect, in addition, the small volume that this winding 24 is shared, so coiling materials'use amount is lower, so can reach effect that manufacturing cost is lower.
