The utility model is provided with a shaft hole, wherein, the outer wall face of which is provided with a combined part with a greater diameter; the inner wall face of the shaft hole is provided with a pivoting part and an oil storage part, wherein, the diameter of which is larger than the diameter of the pivoting part; the combined part and the pivoting part are respectively arranged at the outer and the inner wall faces in a staggered shape.
Description
The utility model belongs to motor component, particularly a kind of Rotor Pin Joint Bearing.
As shown in Figure 1 and Figure 2, the pivot joint bearing 92 of commonly using rotor is generally the copper bearing or the non-ball class bearing of oil-containing.During assembling, be to utilize external force that bearing 92 is forced into central siphon 93 internal diameters, make bearing 92 be the shape that closely cooperates and be combined in central siphon 93 inwalls.Because bearing 92 when being forced into central siphon 93, produces the distortion that becomes undergauge towards the internal diameter direction.Though, this distortion small-sized,, for when it articulates rotation for rotor center axle 91, will cause to make electrical machinery life shorten, easily produce harmful effects such as Rotation Noise; Because the inside and outside wall of bearing 92 forms axial length much at one, therefore, when bearing 92 is oppressed when combining closely in central siphon 93, the shaft hole inner wall 94 of bearing 92 can form irregular comprehensive distortion, therefore, level and smooth central shaft 91 outer wall and the contact friction of bearing 92 internal faces of distortion comprehensively will be caused, so, the central shaft 91 that is articulated in bearing 92 inwalls promptly easily generates Rotation Noise and electrical machinery life is shortened when rotated.
The purpose of this utility model provides a kind ofly can not be out of shape, prolongs electrical machinery life, makes the smooth-going Rotor Pin Joint Bearing of rotor shaft rotation.
The utility model is provided with axis hole, and its outer wall is provided with larger-diameter connecting part; Its shaft hole inner wall face is provided with pin-joint part and the diameter oil storage portion greater than the pin-joint part; Connecting part and pin-joint part are the shape that staggers and are located at the inner-outer wall face respectively.
Wherein:
The connecting part that is located at outer wall is corresponding with the oil storage portion that is located at internal face.
The pin-joint part is arranged on the axis hole two ends; Oil storage portion is positioned between two pin-joint parts.
Outer wall is provided with two connecting parts that are provided with at interval; The shaft hole inner wall face is provided with three pin-joint part and two oil storage portions of staggering and being provided with the connecting part, and two oil storage portions are arranged at respectively between the adjacent pin-joint part.
The connecting part is provided with the axial bore that runs through that forms fluid circulation path.
Because the utility model is provided with axis hole, its outer wall is provided with larger-diameter connecting part; Its shaft hole inner wall face is provided with pin-joint part and the diameter oil storage portion greater than the pin-joint part; Connecting part and pin-joint part are the shape that staggers and are located at the inner-outer wall face respectively.When the utility model connecting part is combined in the shaft tube inner wall face in the mode of combining closely, only can cause corresponding micro-strain in the non-pin-joint part of shaft hole inner wall, and distortion can not caused in the pin-joint part, deformation place can not contacted with central shaft, therefore, central shaft can the generative center deflection in being installed in axis hole of the present utility model the time phenomenon, and also can reduce noise and reduce abnormal friction during rotation, make central shaft obtain more smooth-going rotation, more by being oil storage portion in order to the ring groove of accumulation lubricating oil, provide central shaft more stablizing under the friction state, smooth and easy rotation, the working life of improving the utility model and rotor.Promptly not only can not be out of shape, prolong electrical machinery life, and make the rotor shaft rotation smooth-going, thereby reach the purpose of this utility model.
