Description
Technical field
The utility model relates to electromagnetic equipment field, especially relates to a kind of positioning tool for motor.
Background technology
Traditional positioner that is applied to the assembling of rotary compressor electric machine rotor, generally adopts the spacer shims of arc or Nogata shape.
The shortcoming of the spacer shims of arc: in design, the radian of spacer shims matches with diameter of stator bore or rotor diameter, can guarantee the fit-up gap of rotor, yet, in practical application due to the reasons such as machining accuracy of spacer shims, the available accuracy of arc is poor, thereby causing the radian of part arc spacer shims is non-accurate cooperation with diameter of stator bore or rotor diameter, become the situation of " 3 contacts ", because the contact situation of circumferential each position is all inconsistent, can cause rotor assembling circular gap inhomogeneous.
The shortcoming of the spacer shims of Nogata shape: on the one hand, the seamed edge of the Nogata shape of spacer shims can preferentially contact diameter of stator bore, because spacer shims is reused, the seamed edge camber that can wear and tear gradually, cause actual positioning gap to change, because the abrasion condition of circumferential each position is different, can cause rotor assembling circular gap inhomogeneous; On the other hand, the spacer shims of Nogata shape becomes " contact " at 3 with diameter of stator bore and rotor diameter, and the thickness of spacer shims is less, when bearing out-of-balance force, can occur bending and deformation, thereby cause the effective thickness of spacer shims to diminish, equally also can cause rotor circular gap inhomogeneous.
The positioner of above-mentioned two kinds of traditional electric machine rotor assemblings, all can cause the inhomogeneous situation of rotor assembling circular gap, simultaneously because the circumferential positioning precision of above-mentioned two kinds of positioners is not enough, for guaranteeing the operation possibility of assembling, the design thickness of general spacer shims is: the thickness of the spacer shims of the theoretical fit clearance > arc of rotor or Nogata shape, the effective thickness of spacer shims cannot reach the theoretical fit clearance of rotor, thereby affect the assembly precision of motor, affect performance and the reliability of compressor integral body.
