Description

Electromagnetic speed variator

Technical field:

The utility model relates to speed change gear, is specifically related to a kind of electromagnetic force of utilizing and replaces frictional force to transmit the electromagnetic speed variator of kinetic energy.

Background technology:

At present, mostly many bunchers that mechanically use are to utilize frictional force to conduct power in the prior art.Because friction can produce thermal effect, some mechanical energy can be converted to heat energy and consume in transfer process, and is easy to wearing and tearing machinery.

Summary of the invention:

Technical problem to be solved in the utility model is the defective that overcomes present prior art, provides a kind of electromagnetic force of utilizing to replace frictional force conduction kinetic energy and the electromagnetic speed variator less to mechanical wear.

The utility model is to solve the problems of the technologies described above by following technical scheme.It comprises generator unit stator, generator amature, magnetic pole and winding, and described generator unit stator is a cylindrical shape, is placed on the axle, and its inwall is fixed with magnetic pole, the groove that offers teeth groove on the outer wall or can match with belt; Generator amature also is placed on the axle, and is corresponding with position of magnetic pole, is equipped with in it with generator and derives the winding that line joins, and the control device that generator is derived line and controllable current size joins.Described control device is a ballast, and it comprises movable core, secured core and winding, and wherein winding and generator derivation line joins, and places in the secured core, and movable core is positioned at secured core and winding top, can do slippage along the chute that is fixed on the secured core.

The utility model structural design is simple, realizes easily, because zerofriction force produces, the machinery that can not wear and tear simultaneously, is easy to control and realizes automation as control medium with electric current, and noiselessness pollutes.

Embodiment:

The utility model replaces frictional force to conduct kinetic energy by electromagnetic force.As shown in Figure 1, the utility model comprises generator unit stator 3, generator amature 5, magnetic pole 4 and generator windings 6, and described generator unit stator 3 is a cylindrical shape, be placed on the axle 1, can rotate around this axle 1, axle 1 places on support 2 and the support 7, and between the support 2,7 bearing is housed.At generator unit stator 3 outer surfaces, be processed with teeth groove that can be meshed or the groove that can match with belt with other gear, can under the drive of other power, rotate or output power.In generator unit stator 3 inwall sides, be fixed with magnetic pole 4, at the correspondence position of this magnetic pole 4, be provided with generator amature 5, be fixed on the axle 1 by key, can among axle 1, rotate by the heart.In generator amature 5, also be provided with generator windings 6, link to each other with slip ring 8 by lead, this slip ring 8 links to each other with brush 10, is fixed on the support 7, and brush 10 is derived line 9 with generator and is joined.

The speed change output of the utility model generator realizes by deriving line 9 joining control device 16 with generator.As Fig. 2, shown in Figure 3, this control device 16 can be a ballast, it comprises movable core 11, secured core 12 and ballast winding 13, wherein ballast winding 13 joins with generator derivation line 9, place in the secured core 12, movable core 11 is positioned at secured core 12 and ballast winding 13 tops, handle 14 is housed on it, can drive the chute 15 that the lower edge is fixed on the secured core 12 at it and do slippage, by changing the relative position between movable core 11 and the secured core 12, can change the size of electric current in the ballast.

When with generator unit stator 3 during as power intake, generator unit stator 3 is driven and is relatively rotated with generator amature 5, at this moment, generator is derived line 9 two ends and is produced voltage, generator windings 6 forms electric current after connecting lead, generator amature 5 drives axle 1 to rotate under its electromagnetic force effect and do to rotate in the same way with generator unit stator 3 simultaneously, outputs power.Otherwise during as power intake, generator unit stator 3 rotates under generator windings 6 and magnetic pole 4 effects, outputs power by gear or belt pulley with generator amature 5.In the said structure, the velocity of rotation of generator unit stator 3 and generator amature 5 is by the control of the size of ballast electric current, and when mobile movable core 11, the size of electric current changes in the ballast winding 13, thereby has changed the size of electric currents in the generator windings 6.The change of size of current will cause the change of electromagnetic force size, and generator unit stator 3 or generator amature 5 rotating torques are changed, thereby realize the infinitely variable speeds of power output.

The utility model is used on the vehicle also can doublely make generator, can also brake as friction free simultaneously.
