Description
Technical field
The invention belongs to motor construction technical fields, directly become linear motion more particularly to a kind of rotary motion
Electric machine structure.
Background technique
Motor can be divided into rotating electric machine and linear motor according to the difference of movement output form, and rotating electric machine is the biggest
Well known and the most widely used a kind of motor.
It is loaded using motor driven, and exports rotary motion or linear motion as needed.When needing to export rotary motion,
It can directly be met the requirements by rotating electric machine；If necessary to linear movement output, when using rotating electric machine, it is necessary to cooperate
Screw-nut mechanism or gear and rack teeth mechanism etc. carry out the conversion of motion mode, and not only volume occupies greatly this mode, and
And installation maintenance process is more complicated；If when using linear motor, although linear movement output, straight line can be carried out directly
Electric machine structure is complicated and manufacture difficulty is big, and cost is more much higher than rotating electric machine.
Therefore, when needing linear movement output, existing rotating electric machine and linear motor all still have several drawbacks it
Place, if it is possible to overcome above-mentioned deficiency, and design it is a kind of have both rotating electric machine and linear motor respectively advantage electric machine structure then
It is very necessary.
Summary of the invention
In view of the problems of the existing technology, the present invention provides the motor knot that a kind of rotary motion directly becomes linear motion
Structure has the characteristics that volume occupies that small, manufacture difficulty is low and at low cost, and is suitable for direct current generator, asynchronous machine and synchronizes electricity
The conventional motors such as machine.
To achieve the goals above, the present invention adopts the following technical scheme: a kind of rotary motion directly becomes linear motion
Electric machine structure, including casing, drive end bearing bracket, rear end cap, stator core, rotor core and shaft, the drive end bearing bracket, rear end cap difference
The both ends of casing are mounted on, described shaft one end is connected on drive end bearing bracket by bearing, and the shaft other end is connected to by bearing
On rear end cap, the stator core is fixedly mounted on casing, and the rotor core is fixedly mounted in shaft, its main feature is that:
The shaft uses hollow shaft structure, and linear motion axis is provided on the inside of shaft, and shaft inner surface has internal screw thread, straight line fortune
Moving axis outer surface has external screw thread, and shaft is threadedly engaged with linear motion axis.
The linear motion axis integrally uses chamfered edge axle construction.
Described linear motion axis one end passes through drive end bearing bracket or the centre bore of rear end cap extends to outside casing, and centre bore uses
The rotary freedom of kidney-shaped pore structure, linear motion axis is limited by centre bore.
Beneficial effects of the present invention:
The present invention is compared with traditional rotating electric machine, in linear movement output, it is no longer necessary to screw-nut mechanism or tooth
The conversion that rackwork etc. carries out motion mode is taken turns, occupies volume of the present invention smaller.
The present invention is compared with traditional linear motor, and electric machine structure is simple and manufacture difficulty is low, and especially cost is than straight
Line motor is much lower.

Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Fig. 1~5, a kind of rotary motion directly becomes the electric machine structure of linear motion, including casing 1, drive end bearing bracket 2,
Rear end cap 3, stator core 4, rotor core 5 and shaft 6, the drive end bearing bracket 2, rear end cap 3 are separately mounted to the both ends of casing 1,
Described 6 one end of shaft is connected on drive end bearing bracket 2 by bearing, and 6 other end of shaft is connected on rear end cap 3 by bearing, described
Stator core 4 is fixedly mounted on casing 1, and the rotor core 5 is fixedly mounted in shaft 6, and the shaft 6 uses hollow shaft
Structure is provided with linear motion axis 7 on the inside of shaft 6, and 6 inner surface of shaft has internal screw thread, and 7 outer surface of linear motion axis has
External screw thread, shaft 6 are threadedly engaged with linear motion axis 7.
The linear motion axis 7 is whole to use chamfered edge axle construction.
Described 7 one end of linear motion axis passes through drive end bearing bracket or the centre bore 8 of rear end cap 3 extends to outside casing 1, centre bore
8 use kidney-shaped pore structure, and the rotary freedom of linear motion axis 7 is limited by centre bore 8.
Illustrate first use process of the invention with reference to the accompanying drawing:
Start motor, under electromagnetic force, shaft 6 and rotor core 5 rotate in casing 1, and with shaft 6
The linear motion axis 7 being threadedly engaged will be directly realized by linear motion by the rotary motion of shaft 6.As it can be seen that of the invention
Electric machine structure is compared with traditional rotating electric machine, in linear movement output, it is no longer necessary to screw-nut mechanism or rack-and-pinion
Mechanism etc. carries out the conversion of motion mode, occupies volume of the present invention smaller.Electric machine structure of the invention and traditional straight-line electric
Machine is compared, and electric machine structure is simple and manufacture difficulty is low, and especially cost is more much lower than linear motor.
The scope of patent protection that scheme in embodiment is not intended to limit the invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the patents of this case.
