Abstract

The utility model discloses a kind of pneumatic magneto, and it is linked together at spring cylinder and magneto, and piston is coaxially connected with the armature of magneto, and the excitation rotor of magneto and armature are set with and can rotate.The magnetic field of armature cutting excitation rotor, makes the closed winding on armature produce induced current, forms Induced magnetic field; Because Induced magnetic field always hinders the change in former magnetic field, on armature, so just produce one in the vector magnetic moment of 90 degree: one be the moment contrary with armature movement direction, one be the torque of excitation rotor; When armature is from the process that inner dead point arrival outer dead point also stops, excitation rotor revolves turnback, meanwhile cylinder exhaust, and spring release promotes piston and armature is moved to inner dead point by outer dead point, and excitation rotor rotates 180 again.Utilize the rotary motion of convert reciprocating motion for excitation rotor of spring cylinder and armature, there is no intermediary agency, compact conformation, simple.

Description

Pneumatic magneto

Technical field

The present invention relates to a kind of pneumatic magneto, be specifically related to air motor field.

Background technology

Current air motor is Purely mechanical structure, constructs more complicated, and moving component is easy to wearing and tearing.

Summary of the invention

The invention provides a kind of pneumatic magneto, it is linked together at spring cylinder and magneto, and piston is coaxially connected with the armature of magneto; Symmetrical two pieces of circular arc N poles and S pole permanent magnet in the excitation rotor of magneto, excitation rotor and armature are set with and can rotate.When compressed air enters cylinder, piston is moved to outer dead point by inner dead point, spring is stored the energy of backward stroke of the piston by compressing, the armature moving linearly be connected with piston, the magnetic field of armature cutting excitation rotor, make winding closed on armature produce induced current, form Induced magnetic field; Because Induced magnetic field always hinders the change in former magnetic field, on armature, so just produce one in the vector magnetic moment of 90 degree: one be the moment contrary with armature movement direction, one be the torque of excitation rotor; When armature is from the process that inner dead point arrival outer dead point also stops, excitation rotor revolves turnback, meanwhile cylinder exhaust, and spring release promotes piston and armature is moved to inner dead point by outer dead point, and excitation rotor rotates 180 again.Utilize compressed air to make the rotary motion that piston and armature convert reciprocating motion are excitation rotor, compact conformation, simple, moving component is few.

The present invention is realized by following technical scheme: a kind of pneumatic magneto, comprising: cylinder, the magnetoelectricity casing be connected with cylinder, the spring be sleeved in cylinder, the air valve for cylinder air feed, the armature be connected with piston, the excitation rotor that can rotate be set with armature; It is characterized in that: described cylinder is connected with magnetoelectricity casing, pocketed springs in cylinder, magnetoelectricity casing inner sleeve fills two bearings, arranges spacer, and located by jump ring between two bearings; Piston and armature are linked together by square push rod and can come and go slip; Described excitation rotor to be sleeved between armature and magnetoelectricity casing and and bearing fit.

Described armature core has the silicon steel plate stacking of double flute to be formed by punching, two circular arc type magnetic poles of iron core respectively remove an angle, form asymmetric structure, its objective is the drift angle making to keep about 10 degree between armature and excitation rotor, to ensure that armature can have the direction of rotation determined, be convenient to excitation rotor and start; By coiling enamelled wire in the groove of iron core, two the end of a thread of enamelled wire weld together, and form closed-loop path.

Described excitation rotor is made up of shell and symmetrical two blocks of circular arc permanent magnets in the enclosure and the output shaft that is connected to shell one end; The length of two described block permanent magnets is slightly less than the axial length of armature and the interior outer dead point stroke sum of piston.

Good effect of the present invention

1. utilize compressed air to make the rotary motion that piston and armature convert reciprocating motion are excitation rotor, structure is simple, and moving component is few.

2. manufacture craft is simple, and conventional manufacturing process can realize.
