Label declaration
1 master gear, 2 bearings, 3 subordinate gears, 4 subordinate bearings, 5 positive triangle magnetic patch, 6 little magnetites, 7 pads, that "+" among the figure number represents is anodal, "-" number represents negative pole.
Embodiment
The utility model is a kind of magnetic gear drive, the master gear that has bearing 21 that it is provided with in the middle of comprising and being positioned at around the master gear and the contacted subordinate gear 3 of master gear, the subordinate gear is the subordinate gear that has subordinate bearing 4, described master gear is that magnetized master gear, subordinate gear also are magnetized subordinate gear, the magnetic of the outer ring of master gear is opposite with the magnetic of inner ring, the outer ring magnetic of subordinate gear is also opposite with inner ring magnetic, and the magnetic of the magnetic of the outer ring of master gear and subordinate gear outer ring is identical magnetic.
Described subordinate gear is 1 ~ 6, subordinate gear more than 2 is provided with equilateral triangle magnetic patch 5 between two subordinate gears, a drift angle of described equilateral triangle magnetic patch is opposite with the magnetic on base, and the magnetic on base is identical with the magnetic of the outer ring of master gear, described equilateral triangle magnetic patch drift angle formed angle between master gear and subordinate gear, one of them base angle of equilateral triangle magnetic patch is formed angle between master gear and another subordinate gear, and the tangent direction of the direction of drift angle and master gear moving direction is opposite.
Be provided with in the place that master gear contacts with bearing and can weaken and the pad 7 of isolated magnetic, also be provided with in the place that the subordinate gear contacts with the subordinate bearing and can weaken and the pad of isolated magnetic.By increasing the loss that pad can delay master gear and subordinate gear magnetic force, prolong working life of the present utility model.
As shown in Figure 1, the master gear that has bearing that the utility model is provided with in the middle of comprising and being positioned at around the master gear and the contacted subordinate gear of master gear, the subordinate gear also has the subordinate bearing: described master gear is that magnetized master gear, subordinate gear also are magnetized subordinate gear, the magnetic of the outer ring of master gear is anodal, the magnetic of inner ring is negative pole, and the outer ring magnetic of subordinate gear is for also being anodal, and the magnetic of inner ring is negative pole.
Described subordinate gear is 6, between two subordinate gears, be provided with the equilateral triangle magnetic patch, a drift angle of described equilateral triangle magnetic patch is opposite with the magnetic on base, the magnetic on base is anodal, described equilateral triangle magnetic patch drift angle formed angle between master gear and subordinate gear, one of them base angle of equilateral triangle magnetic patch is formed angle between master gear and another subordinate gear, and the tangent direction of the direction of drift angle and master gear moving direction is opposite.
Because the principle that the same sex is repelled each other, the rigidity that has reduced master gear and subordinate gear contacts, the power of can effectively reducing friction, make master gear energy loss in the process of transmission, between two subordinate gears, increase the triangle magnetic patch and can utilize the principle that the same sex is repelled each other, there is a natural attraction between the sexes, the gear of triangle magnetic patch both sides is subjected to the attraction force and the repulsive force of triangle magnetic patch respectively, can further reduce the influence of the frictional force that the subordinate gear is subjected to, further the usefulness of saving.
Embodiment 2
As shown in Figure 2, on embodiment 1 basis, on each tooth of master gear, inlay several little magnetites 6, the little magnetite one side opposite with master gear outer ring magnetic outwardly, and magnetite is embedded on the opposite flank of tooth of the tangential direction of master gear moving direction.That is to say and on each tooth of master gear, inlay several little magnetites, the positive pole of little magnetite outwardly, and magnetite is embedded on the opposite flank of tooth of the tangent direction of master gear moving direction.
In the master gear rotating process, can further utilize the principle that there is a natural attraction between the sexes by on the opposite flank of tooth of the tangent direction of master gear moving direction, inlaying magnetite, because subordinate gear outer ring is anodal, and magnetite one side outwardly attracts each other with the subordinate gear, thereby further reduce the influence of the frictional force that the subordinate gear is subjected to, further the usefulness of saving.
