Abstract
The utility model relates to a kind of rotor, comprise mandrel, the circumference outside of described mandrel is provided with resilient bushing, described mandrel is radially provided with baffle ring, the end of baffle ring is outwards provided with projection, is provided with special-shaped permanent magnetism stone in the outside of resilient bushing, and the outer surface of described permanent magnetism stone and protruding inner surface interference fits are installed, on the permanent magnetism stone surface of winding around, offer several air-vents, the end face of described permanent magnetism stone is the arcwall face caving inward.The utility model is simple in structure, by be fixedly installed baffle ring on mandrel, because the lug boss of permanent magnetism stone and baffle ring has adopted interference fits, provides certain pretightning force, prevents in high speed rotating process, avoids producing and rocks, and suppresses noise and vibration; By air-vent is set, improve radiating effect; By winding around on special-shaped permanent magnetism stone, improve magnetic flux.
Description
Technical field
the utility model relates to motor part field, relates in particular to a kind of rotor.
Background technology
rotor is the rotating parts in motor, and motor is made up of rotor and stator two parts, and it is the conversion equipment for realizing electric energy and mechanical energy and mechanical energy and electric energy.Rotor is divided into two kinds of internal rotor rotating manner and external rotor rotating manners; Internal rotor rotating manner is that the core body in the middle of motor is rotary body, output torque or income energy, and external rotor rotating manner is taking motor ectosome as rotary body, and different modes has facilitated the application of various occasions.
rotor of the prior art can produce violent vibrations in the time running up, and also can produce great noise simultaneously, and adhesive in rotor is difficult for dryly, has reduced the intensity of bonding, has shortened the useful life of rotor, has reduced the reliability of working rotor.
be a kind of rotor that 201220307398.X announces according to Chinese Patent Application No., comprise mandrel, permanent magnetism stone, resilient bushing and aperture, mandrel outside is provided with permanent magnetism stone, between mandrel and permanent magnetism stone, is provided with resilient bushing, and mandrel and resilient bushing two ends are provided with aperture.This simple in structure, easy to assembly quick, connect reliably, can avoid larger vibrations and the problem of noise.But the rotor magnetic flux of this structure is little, radiating effect is poor, easily produce and rock simultaneously, cause job insecurity.
Utility model content
in order to overcome the deficiencies in the prior art, the utility model provides a kind of rotor, connects reliably, in High Rotation Speed process, is difficult for rocking, and improves radiating effect simultaneously.
the utility model is achieved in that
a kind of rotor, comprise mandrel, the circumference outside of described mandrel is provided with resilient bushing, described mandrel is radially provided with baffle ring, the end of baffle ring is outwards provided with projection, be provided with special-shaped permanent magnetism stone in the outside of resilient bushing, the outer surface of described permanent magnetism stone and protruding inner surface interference fits are installed, and on the permanent magnetism stone surface of winding around, offer several air-vents.
as optimal technical scheme of the present utility model, the end face of described permanent magnetism stone is the arcwall face caving inward.
as optimal technical scheme of the present utility model, described air-vent is circular hole, and its diameter is 10mm.
compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, by be fixedly installed baffle ring on mandrel, because the lug boss of permanent magnetism stone and baffle ring has adopted interference fits, certain pretightning force is provided, prevent in high speed rotating process, avoid producing and rock, suppress noise and vibration; By air-vent is set, improve radiating effect; By winding around on special-shaped permanent magnetism stone, improve magnetic flux.
Brief description of the drawings
fig. 1 is structural representation of the present utility model.
in figure: 1-mandrel; 2-resilient bushing; 3-baffle ring; 4-permanent magnetism stone; 5-air-vent; 6-arcwall face.
Embodiment
in order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
described a kind of rotor, comprise mandrel 1, the circumference outside of described mandrel 1 is provided with resilient bushing 2, and described mandrel 1 is radially provided with baffle ring 3, and the end of baffle ring 3 is outwards provided with projection, be provided with special-shaped permanent magnetism stone 4 in the outside of resilient bushing 2, permanent magnetism stone 4 adopts sintered neodymium iron boron material to make. and the outer surface of described permanent magnetism stone 4 and protruding inner surface interference fits are installed, and certain pretightning force is provided, and prevent in high speed rotating process, avoid producing and rock, suppress noise and vibration.The end face of described permanent magnetism stone 4 is the arcwall face 6 caving inward, and occurs sliding while preventing from just starting winding around.
on permanent magnetism stone 4 surfaces of winding around, offer several air-vents 5, be convenient to breathe freely, improve the radiating effect of rotor, described air-vent 5 is circular hole, and its diameter is 10mm.
the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
