Abstract
The utility model discloses a motor shaft has solved the pivot intensity of micro -machine not high and pivot and the fixed insecure problem of rotor coil, and its technical scheme main points are: be equipped with a plurality of strengthening ribs on the axis body, the both sides that lie in the strengthening rib on the axis body are equipped with annular oil groove along the circumference of axis body, and the one end of axis body is equipped with the terminal surface and at the coaxial double -screw bolt that is fixed with of the other end that radially is equipped with opening, axis body of this end edge axis body. Strengthening rib on the axis body is the intensity of multiplicable axis body both, can be used to fixed rotor coil again, and the fixed mode of this kind is more reliable. In addition, the opening of locating the axis body tip can make this tip take place deformation, is convenient for install external component.
Description
Technical field
The utility model relates to a kind of mechanical parts, and more particularly, it relates to a kind of motor shaft.
Background technique
Motor is widely used in, in the daily life of industrial and agricultural production and people, having become indispensable equipment.Motor is made up of rotating shaft, rotor coil, stator and housing, and rotor coil to be fixed in rotating shaft and to be communicated with rotating shaft and rotates together, and rotating shaft is connected with housing into rotation by bearing.At present, micro-machine on the market, the diameter of its rotating shaft is very thin, its rotor coil is bonding with rotating shaft glue or pass through straight burr (projection) clamping, such motor, the intensity of its rotating shaft is general not high, the situation of shaft bending card machine is easily there is after working long hours, this outer shaft and rotor coil pass through the bonding motor of glue, easily occur glue failure conditions thus both connections are loosened, shaft bending and rotating shaft are connected the operation that situation about loosening all can have a strong impact on motor with rotor coil.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of motor shaft, and the intensity of this motor shaft is higher, and not easily loosens after fixing with rotor coil.
For achieving the above object, the utility model provides following technological scheme:
A kind of motor shaft, comprise axis body, axis body is provided with some stiffening ribs, the both sides that axis body is positioned at stiffening rib are circumferentially with annular oil groove along axis body, one end of axis body is axially arranged with tangent plane at its sidewall along it, and the one end being provided with tangent plane is provided with otch at its end face along the radial direction of axis body, the other end of axis body is coaxially fixed with stud.
Further, the quantity of stiffening rib is 8, and stiffening rib is uniformly distributed along the circumference of axis body.
Further, the length of the axis body part between two oil grooves is 75.496 ~ 75.504mm, and the length of muscle is 20mm.
Further, the length of axis body is 164.96 ~ 165.04mm, and the diameter of axis body is 7.996 ~ 8.004mm.
Further, the length direction of otch is parallel to end face.
Further, the width of otch is the 1.5mm degree of depth is 2mm.
Compared with prior art, the utility model has the advantages that: the stiffening rib on axis body both can increase the intensity of axis body, can be used for again fixed rotor coil, and this kind of means of fixation is more reliable.In addition, the opening being located at axis body end can make this end that deformation occurs, and is convenient to install external component.

Description of reference numerals: 1, stiffening rib; 2, oil groove; 3, tangent plane; 4, otch; 5, stud.
Embodiment
With reference to Fig. 1, a kind of motor shaft, comprises axis body, and the length of axis body is 164.96 ~ 165.04mm, and the diameter of axis body is 7.996 ~ 8.004mm, and traditional micro-machine rotating shaft, due to the restriction of size, exists the problem that structural strength is not high.Be topic for overcoming above-mentioned, the utility model is provided with stiffening rib 1 on axis body, and stiffening rib 1 is uniformly distributed along the circumference of axis body, and according to the actual requirements and contact manufacture difficulty and cost, the quantity of stiffening rib 1 is preferably 8, and the length of stiffening rib 1 is 20mm.The intensity that stiffening rib 1 can increase axis body can be used for again fixed rotor coil, and the both sides that axis body is positioned at stiffening rib 1 are circumferentially with annular oil groove 2 along axis body, and the length of the axis body part between two oil grooves 2 is 75.496 ~ 75.504mm.One end of axis body is provided with tangent plane 3 and is provided with otch 4 at this end along the radial direction of axis body, tangent plane 3 for exterior part clamping, the rotating shaft of motor and the snap fit of exterior part are: the blocked hole of exterior part is inserted in one end that machine shaft has a tangent plane 3, the shape of the blocked hole of exterior part is corresponding with the shape of this tangent plane 3, carrys out clamping with this.But, because processing system exists error, sometimes blocked hole is inserted in rotating shaft, if both size errors are excessive, possibly rotating shaft cannot be inserted blocked hole, thus cannot clamping.Therefore, otch 4 has been offered in the one end in rotating shaft with tangent plane 3, and the width of otch 4 is the 1.5mm degree of depth is 2mm, and the length direction of otch 4 is parallel to tangent plane 3.The object offering otch 4 has two: one, and the existence of otch 4 can make the joint end of rotating shaft within the specific limits deformation occur, thus avoid because of machining error cause too greatly cannot clamping problem occur; Its two, otch 4 can be used for engaging with the outstanding position of exterior part, makes the snap fit of rotating shaft and exterior part more various, extends the Applicable scope of rotating shaft.In addition, the stud 5 being located at the rotating shaft the other end is that the connection of rotating shaft and exterior part provides another and selects.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
