Abstract
Positioning formula machine shaft, including machine shaft body, the machine shaft body is rotatably assorted with motor rotor core, the outer wall of the machine shaft body is provided with for hot jacket or press-fits the mating surface of motor rotor core, the end of the mating surface wherein side is circumferentially with the step for positioning, the step is provided with the step end face for propping up motor rotor core towards the side of mating surface, and the step end face of the step is tight with the installation end face pressure of motor rotor core.The beneficial effects of the utility model are：1) positioning formula machine shaft simple structure, easy to process, ensures without other technology and pattern assemblies, is usable in miniature, small-sized, the big-and-middle-sized all kinds of electronic products of various plain shaft structures；2) in rotor rotor production process, the situation that tradition ensures positioning by technology and pattern assembly is changed, when making motor rotor core in hot jacket or colding pressing onto motor shaft, energy one-time-reach-place, it is not necessary to manually adjust, saved time, human and material resources.
Description
Technical field
The utility model is related to a kind of positioning formula machine shaft.
Background technology
In conventional motors pivot design and manufacture, machine shaft does not have a positioning step, rotor core hot jacket or colds pressing
When in rotating shaft, orientation problem can only lean on frock or workman to hold by hand, occur motor caused by deviations often
Stator and rotor iron core is not lined up and influences the problem of motor performance.In order that can make, rotor is more time saving and energy saving in the mill to save worry, and presses
According to the size positions of stator and rotor iron core, positioning step is directly increased on axle, so as to ensure that guaranteeing both quality and quantity for rotor production,
Save substantial amounts of time cost and cost of labor.
The content of the invention
Artificial operation is needed when the utility model is installed for current machine shaft with rotor core, causes deviations to lead
The motor stator and rotor iron core of cause is not lined up and influences the problem of motor performance, it is proposed that one kind need not be positioned manually, and be mounted directly
Positioning formula machine shaft.
Positioning formula machine shaft described in the utility model, including machine shaft body, the machine shaft body and electricity
Machine rotor iron core is rotatably assorted, and the outer wall of the machine shaft body is provided with for hot jacket or press-fits the cooperation of motor rotor core
Face, it is characterised in that：The end of the mating surface wherein side is circumferentially with the step for positioning, and the step direction coordinates
The side in face is provided with the step end face for propping up motor rotor core, step end face and the motor rotor core of the step
Installation end face pressure is tight.
The step is cylindrical structure, and the external diameter of the step is more than the external diameter at the machine shaft mating surface.
The step end face of the step is vertical with the axis of machine shaft body.
Positioning formula machine shaft manufacture material described in the utility model can wide selection engineering material, such as 45 steel, 40Cr,
Q235 etc., and machine shaft body shape is columnar step formula, and outer diameter of step is slightly larger than the normal external diameter of machine shaft body, platform
External diameter and thickness can be designed according to actual conditions at rank, as long as can guarantee that rotor core is reliably installed in place.
The beneficial effects of the utility model are：1) positioning formula machine shaft simple structure, easy to process, without other techniques
Frock ensures, is usable in miniature, small-sized, the big-and-middle-sized all kinds of electronic products of various plain shaft structures；2) this utility model is put
Traditional optical axis is abandoned without location structure, by positioning formula step pivot design, in rotor rotor production process, tradition is changed by work
Skill frock ensures the situation of positioning, and when making motor rotor core in hot jacket or colding pressing onto motor shaft, energy one-time-reach-place is not required to
Manually adjust, saved time, human and material resources.

Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings
Referring to the drawings：
The positioning formula machine shaft described in the utility model of embodiment 1, including machine shaft body 1, the machine shaft
Body 1 is rotatably assorted with motor rotor core 2, and the outer wall of the machine shaft body 1 is provided with for hot jacket or press-fits motor turn
The mating surface 11 of sub- iron core, the end of the wherein side of the mating surface 11 is circumferentially with the step 12 for positioning, the step
12 are provided with the step end face for propping up motor rotor core 2 towards the side of mating surface, the step end face of the step 12 with
The installation end face pressure of motor rotor core 2 is tight.
The step 12 is cylindrical structure, and the external diameter of the step 12 is more than the mating surface 11 of the machine shaft body 1
The external diameter at place.
The step end face of the step 12 is vertical with the axis of machine shaft body 1.
Positioning formula machine shaft manufacture material described in the utility model can wide selection engineering material, such as 45 steel, 40Cr,
Q235 etc., and machine shaft body 1 is shaped as columnar step formula, and the external diameter of step 12 is normal slightly larger than machine shaft body 1 outer
Footpath, external diameter and thickness can be designed according to actual conditions at step 12, as long as can guarantee that rotor core 2 is reliable being installed in place.
Content described in this specification embodiment is only enumerating to the way of realization of utility model design, and this practicality is new
The protection domain of type is not construed as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model is also wrapped
Include those skilled in the art according to the utility model design it is conceivable that equivalent technologies mean.
