Embodiment
below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is further elaborated.
referring to the motor shown in Fig. 1, Fig. 3 and Fig. 5, this motor comprise have inner chamber casing 1, be housed in stator 2 in casing 1 inner chamber and rotor 3, the exportable motor shaft rotatablely moving 4.Under the effect of stator 2 excitations, produce continuous rotatablely moving, thus drive motor axle 4 continuous rotations.
this motor also comprises the axial cam on the output that is fixed on motor shaft 4, and is hinged on fork swingable on support 10, and support can be any fixed part on motor herein, and for example front end housing 6 also can be the external stability seat for mounted motor.Axial cam has the inner side axle head and the outside axle head that lay respectively at both sides, and the output of its inner side axle head and motor shaft 4 is fixedly connected, and its outside axle head offers the cam path of closed.One side shaft end of fork 10 is provided with guide 9, be located in cam path to these guide 9 matched in clearance, like this, in the time that rotating, motor shaft 4 can drive axial cam to rotate around Pivot Point Center line, under the effect of cam path, fork 10 swings accordingly, and the opposite side axle head of fork 10 is exported oscillating motion, makes this motor output oscillating motion.
one end of casing 1 is also provided with and is fixed with front end housing 6, and for axial cam being housed in its inner chamber, the swing output of fork 10 is positioned at the outside of front end housing 6, thereby connects the parts of other demand motives.
axial cam has the multiple form that arranges, and provides following three kinds of specific embodiments in the utility model:
embodiment 1
shown in Fig. 1, Fig. 2, this axial cam is Internal Spherical Surface axial cam 51, its outside axle head has the Internal Spherical Surface 71 axially concaving along it, cam path 8 is opened in this Internal Spherical Surface 71, like this under the effect of Internal Spherical Surface 71 and cam path 8, motor shaft 4 rotations can drive fork 10 to do continuous oscillating traverse motion around its hinged point, make this motor output oscillating traverse motion.
embodiment 2
shown in Fig. 3, Fig. 4, axial cam is set to inner conical surface cam 52, its outside axle head has the inner conical surface 72 axially concaving along it, cam path 8 is opened in this Internal Spherical Surface 72, like this under the effect of inner conical surface 72 and cam path 8, motor shaft 4 rotations can drive fork 10 to do continuous oscillating traverse motion around its hinged point, make this motor output oscillating traverse motion.
embodiment 3
shown in Fig. 5, Fig. 6, axial cam is set to axial globoid cam 53, on its outside axle head, there is the depressed part axially caving inward along it, this depressed part forms two camber lines 73 on any axial cross section of this axial globoid cam 53, these two camber lines 73 are along the axial indent of this axial globoid cam 53 and be distributed in symmetrically the axial line both sides of axial globoid cam 53, that is this depressed part is around the axial line rotation of axial globoid cam 73 and form with the camber line of an indent.Cam path 8 is opened in the cambered surface of this depressed part.
in this embodiment, fork 10 can be set to one or more, and one end of each fork 10 all can arrange guide 9, is located in cam path 8 to these multiple guide 9 equal matched in clearance.Motor shaft 4 rotations can drive these multiple forks 10 to swing simultaneously simultaneously like this, obtain the oscillating motion of multiple outputs in parallel.This is specially adapted to need the occasion of multiple oscillating motion driven members output in parallel.The mode of comparing traditional footpath at cam and upwards arranging rocking bar in parallel is set like this, and its space arranges very easy and structure is more compact, takes up room relatively little.
under this embodiment, if when the number of fork 10 is two, the bionic movement of rubbing for similar both hands of this motor output.
in the various embodiments described above, the curve shape of cam path 8 can and need the oscillating motion of output to design in conjunction with the structure of axial cam, thereby make the swing output of fork 10 export different angular displacements, displacement and acceleration, make it meet different designing requirements, also make motor be applicable to different application demands.
