Description
Technical field
The utility model relates to a kind of clutch, especially relates to a kind of hysteresis cluth.
Background technology
It is several that employed clutch has slip clutch, electromagnetic clutch, permanent-magnetic clutch etc. in the present prior art.
The slip clutch volume is larger, in combination or separation process, to produce sliding friction, so the heating trial of strength is large, it is also larger to wear and tear, cause reliability to reduce because of friction disc wear after long-term the use, slip clutch uses also unstablely under the vibrations condition in addition, can not satisfy high accuracy, high reliability request.
The characteristic of electromagnetic clutch of the prior art is softer, and rotating speed diminishes with the increase of moment, although the characteristic of magneto is harder, higher frequency jitter is arranged after it skids, and can not recover running in the situation that moment reduces, and the moment size adjustment is inconvenient.
The utility model content
In view of the existing deficiency of the clutch of prior art.The purpose of this utility model is to provide that a kind of volume is little, reliability is high, slipping torque is large, not relying on a kind of hysteresis cluth that friction produces the advantages such as moment.
For realizing above-mentioned purpose of the present utility model, the utility model provides a kind of hysteresis cluth, comprising: an external stator; Internal stator, described internal stator are arranged in the described external stator; One power shaft, described power shaft is by the rotating described external stator middle part that is sheathed on of a bearing; One magnet exciting coil, described magnet exciting coil are arranged in the described external stator; One rotor and a rotating shaft, described rotating shaft is arranged at the middle part of described rotor and corresponding described power shaft setting by a close-fitting ring; Described internal stator comprises one first internal stator, the second internal stator and one the 3rd internal stator, and described the first internal stator is arranged at the bottom of the center of inside of described external stator; Described the second internal stator and described the 3rd internal stator spacing are sheathed on the top of described the first internal stator; Described rotor is arranged in the gap of described the second internal stator and the 3rd internal stator; Described the second internal stator outer wall and the 3rd internal stator inwall are respectively equipped with the air gap groove, and described air gap groove mutual dislocation is arranged, and described the second internal stator outer wall and the 3rd internal stator closely link together by a magnetic pole clamping ring.
According to above-mentioned design of the present utility model, be respectively N on the gap of described external stator and described the 3rd internal stator, the S utmost point is staggered, and be uniformly distributed on the gap of described external stator and described the 3rd internal stator.
According to above-mentioned design of the present utility model, described magnetic pole clamping ring is a unmagnetized magnetic pole clamping ring.
According to above-mentioned design of the present utility model, described rotating shaft is provided with two can prevent that the magnetic hysteresis rotor is not affected by axial force and the jump-ring slot that skids off.
Advantage of the present utility model and beneficial effect are: hysteresis cluth of the present utility model is in certain torque range; keep identical slipping torque and flex point moment; and externally the moment of resistance reaches before the flex point moment; without relatively rotation, the rotating speed that transmits can not descend between the rotor, and clutch plays good gearing; and when external drag moment reaches flex point moment; produce relative motion between rotor and the interior external stator, clutch skids rapidly, plays a protective role.Utilize the hysteresis characteristic of magnetic material to work, contactless between stator and the rotor, can not generate heat without friction, so reliability is high.Have that volume is little, reliability is high, slipping torque is large, do not rely on friction and produce the advantages such as moment.
