In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of rotor of motor and the radially jockey of rotating shaft, make as far as possible torsion that rotor is delivered to rotating shaft and load in other words torque ripple reduce simplified structure and production technology simultaneously.
The utility model is achieved by the following technical solution: it comprises rotor and rotating shaft, rotor comprises internal rotor and magnetic external rotor, shaft set is in the internal rotor the inside, internal rotor is enclosed within the external rotor the inside, between internal rotor and external rotor, form the space, the outer surface of internal rotor and the inner surface of external rotor are respectively arranged with several pits, at the pit of the outer surface of internal rotor with in the space between the pit of the inner surface of corresponding external rotor the transmission damper unit is installed with it, the outer surface of transmission damper unit is nested into the pit the inside.
The grafting piece that above-mentioned described transmission damper unit can be rubber or asynthetic rubber.
Above-mentioned described transmission damper unit can be made up of rubber ring and connecting pin, has the hole in the middle of the rubber ring, is inserted with connecting pin in the inside, hole.
The pit number of the inner surface setting of the outer surface of above-mentioned described internal rotor and external rotor can be 2 to 60 scopes.
The inner surface that the outer surface of above-mentioned described internal rotor is provided with pit and external rotor is provided with the position of pit and can aligns, and also can stagger.
Above-mentioned described pit is that the cross section is circular arc or rectangle, and the outer surface cross section of transmission damper unit is circle or rectangle.
Above-mentioned described connecting pin can connect, and also can not connect.
Above-mentioned described internal rotor and external rotor be provided with that pit can connect, also can be not connect.
2 to 60 transmission damper units are installed between above-mentioned described internal rotor and the external rotor.
The transmission damper unit of installing between above-mentioned described internal rotor and the external rotor can link all-in-one-piece.
The utility model compared with prior art has following advantage: 1) utilize rubber ring and connecting pin to carry out transmission or adopt rubber grafting piece directly to drive, rubber grafting piece and rubber ring adopt thin rubber manufacturing, avoid traditional structure to adopt the thicker block rubber of a monoblock as actuated element, saved material, reduce cost, can dwindle the radial dimension of whole rotor; 2) traditional employing one monoblock block rubber is as actuated element, amplitude of deformation is big during the rubber transmission, the transmission response lag, utilize rubber ring of the present utility model and connecting pin to carry out transmission altogether, the distortion of transmission damping ring is little, main by the metallic pin transferring power, both can reach the purpose of vibration damping, increase the speed of response simultaneously; 3) 2 to 60 transmission damper units can evenly be set between internal rotor and external rotor, more even when making transmission of power, reduce vibrations and noise; 4) structure advantages of simple more is easier for installation.
