Description

The magnetic motivation

The utility model relates to a kind of magnetic motivation, belongs to the dynamic power machine technical field of magnetic force as power source.

At present, magnetic motivation of the prior art, generally all be as stator and rotor with permanent magnet, and generally all be to be fixed on these permanent magnets in the casing and to be fixed on the iron core of rotor as stator and rotor, when the magnetic engine operation, its rotating speed generally all can not change, and is therefore very inconvenient in use; In addition, because the permanent magnet that is installed on the rotor magnetic core is fixed, the NS extreme direction of its permanent magnet just can not change after installing, when rotor rotates, being fixed on epitrochanterian permanent magnet magnetic force line will take place constantly to change with the direction that permanent magnet magnetic force line as stator cuts mutually, therefore cutting the moment size that rotor is produced mutually by the magnetic line of force also will take place constantly to change, this not only makes the rotary speed unstabilization of magnetic motivation fixed, and because the direction can not guarantee epitrochanterian permanent magnet magnetic force line and permanent magnet magnetic force line as stator cuts mutually when the magnetic engine operation time remains on 90 cut direction of spending, promptly reach the cut direction of maximum moment, so the magnetic motivation can not be given full play to its due magnetic force efficient.

The purpose of this utility model is: a kind of magnetic motivation that can give full play to the magnetic force efficient of magnetic motivation and can control its rotating speed easily is provided.

The utility model is to constitute like this: it comprises casing (1), permanent magnet (2) as stator, power output shaft (3), rotor core (4), bearing (5), permanent magnet (2) is fixed in the casing (1), bearing (5) is contained on the casing (1), rotor core (4) is contained on the power output shaft (3), power output shaft (3) is contained on the bearing (5), two end caps (6) and a location key seat (13) also are housed on power output shaft (3), on the circumference of two end caps (6), evenly distribute at least 8 above cylindrical permanent magnet rods (7) are installed, the quantity of bar magnet (7) is mainly determined according to the power output of magnetic motivation, when the magnetic engine power big more, then the quantity of bar magnet (7) just requires many more, the quantity of bar magnet (7) can be even numbers or odd number, end at every bar magnet (7) has ratchet and sprocket (8), rotating gear wheel (9) is installed in casing (1), go up the tooth piece (10) that symmetry is equipped with two energy and the gears engaged of ratchet and sprocket (8) at gear wheel (9), speed governing axle (11) is installed on casing (1), governor gear (12) with gear wheel (9) engagement is housed on speed governing axle (11), an alignment pin (14) and a spring (15) that has the inclined-plane all is equipped with in the below that corresponds respectively to each ratchet and sprocket (8) on location key seat (13), and each alignment pin (14) all contacts with the ratchet of a ratchet with sprocket (8) respectively.

Because the utility model is installed in epitrochanterian permanent magnet and can makes independently moving with respect to rotor in rotor rotation, the direction that epitrochanterian permanent magnet magnetic force line and permanent magnet magnetic force line as stator are cut mutually remains at the cut direction of 90 degree, thereby magnetic force is always maximum to the moment that rotor produced, thereby given full play to the magnetic force efficient of magnetic motivation; In addition, the utility model adopts the direction that changes the permanent magnet NS utmost point on the rotor, make it to change with the direction that permanent magnet magnetic force line as stator cuts mutually, thereby change magnetic force to moment that rotor acted on, the direction of cutting mutually when epitrochanterian permanent magnet magnetic force line and permanent magnet magnetic force line as stator is spent when 90 degree change from 0, its magnetic force becomes maximum to the moment that rotor produced by zero, thereby can start the magnetic motivation, stop and speed regulating control, so the utility model compared with prior art, have and to give full play to magnetic motivation efficient, and can control the advantage of magnetic engine speed easily, the utility model also has simple in structure in addition, cost of manufacture is cheap, advantages such as reliable operation.The utility model is when work, the speed governing axle of adjusting on the casing (11) turns an angle gear wheel (9) earlier, rotate by being contained in ratchet and the sprocket (8) that two tooth pieces (10) on the gear wheel drive on the bar magnet (7) with its engagement like this, thereby change the pole orientation of this bar magnet (7), thereby the mutual magneticaction moment between stator permanent magnet (2) and the epitrochanterian bar magnet (7) is increased gradually by zero, thereby make power output shaft (3) begin to rotate, when power output shaft (3) rotates, all bar magnets (7) are all stirred by tooth piece (10) by ratchet and sprocket (8), make the magnetic line of force of bar magnet (7) meet the requirements of angle with the angle that stator permanent magnet (2) magnetic line of force cuts mutually.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A cross-sectional schematic of accompanying drawing 1;

Accompanying drawing 3 is the B-B cross-sectional schematic of accompanying drawing 1.

Embodiment of the present utility model: permanent magnet (2) is fixed in the casing (1), bearing (5) is contained on the casing (1), rotor core (4) is contained on the power output shaft (3), power output shaft (3) is contained on the bearing (5), on power output shaft (3), fixedly load onto two end caps (6) and a location key seat (13) again, on the circumference of two end caps (6), evenly distribute 16 cylindrical permanent magnet rods (7) are installed, ratchet of end fixed installation and sprocket (8) at every bar magnet (7), a rotating gear wheel (9) is installed in casing (1), go up the tooth piece (10) that symmetry is loaded onto two energy and the gears engaged of ratchet and sprocket (8) at gear wheel (9), on casing (1), install speed governing axle (11), on speed governing axle (11), load onto governor gear (12) with gear wheel (9) engagement, on location key seat (13), correspond respectively to the ratchet of each bar magnet (7) and the below of sprocket (8) and all load onto an alignment pin (14) and a spring (15) that has the inclined-plane, each alignment pin (14) is all contacted with the ratchet of a ratchet with sprocket (8) respectively, like this when ratchet and sprocket (8) by tooth piece (10) when stirring, the inclined-plane that the ratchet flank of tooth of ratchet and sprocket (8) promotes alignment pin (14) is withdrawn alignment pin downwards, thereby ratchet and sprocket (8) drive bar magnet (7) and can rotate along a direction, and because the another side of alignment pin (14) does not have the characteristics of the ratchet structure of inclined-plane and ratchet and sprocket (8), thereby make ratchet and sprocket (8) when rotating round about its ratchet pin that is positioned block and can not rotate, thereby guaranteed the operate as normal of magnetic motivation.
