Abstract
The utility model relates to a commutator which comprises a pressing ring, pole pieces and a skeleton. The skeleton is a tubular member. A center portion of the tubular member is provided with a skirt rim. Three pole pieces are uniformly distributed along the skirt rim. Each of the pole pieces comprises a main piece and a supporting pin. The main piece is perpendicular to the supporting pin. The main pieces are adhered to an outer peripheral face of a skeleton tubular portion. The supporting pins are adhered to the skirt rim and are extended out of the skeleton. The pressing ring is pressed on the supporting pins of the pole pieces and fixes the pole pieces to the skeleton. Three insulated ribs are uniformly distributed on the skeleton tubular outer peripheral face. The insulated ribs are arranged along the axial direction of the skeleton. The insulated ribs are clamped between the main pieces of the adjacent pole pieces. The insulated ribs are prepared from an insulated material. With the above scheme, the utility model provides the commutator of good symmetry.
Description
Technical field
The utility model is specifically related to a kind of commutator.
Background technology
Commutator is commonly called as commutator, is in order to allow motor continue parts that rotate on the motor.Existing commutator comprises trim ring, pole piece and skeleton, described skeleton is tubular element, and the tubular element middle part is provided with the shirt rim, and three pole pieces evenly distribute along the shirt rim, pole piece comprises main leaf and leg, main leaf is vertical with leg to be arranged, main leaf applying skeleton tube outer peripheral face, and skeleton is also stretched out in leg applying shirt rim, trim ring is installed with in the leg of pole piece pole piece is fixed in skeleton, the position of such commutator pole piece main leaf very easily changes, and causes symmetry not enough, thereby has affected the stability of motor.
Summary of the invention
For the deficiency that prior art exists, the commutator that provides a kind of symmetry good is provided the purpose of this utility model.
For achieving the above object, the utility model provides following technical scheme: a kind of commutator, comprise trim ring, pole piece and skeleton, described skeleton is tubular element, the tubular element middle part is provided with the shirt rim, three pole pieces evenly distribute along the shirt rim, pole piece comprises main leaf and leg, main leaf is vertical with leg to be arranged, main leaf applying skeleton tube outer peripheral face, skeleton is also stretched out in leg applying shirt rim, trim ring is installed with in the leg of pole piece pole piece is fixed in skeleton, it is characterized in that: described skeleton tubulose outer peripheral face evenly distributes and is provided with three bar insulation muscle, and described insulation muscle axially arranges along skeleton, described insulation muscle is located between the main leaf of adjacent pole piece, and described insulation muscle is made by insulating material.
By adopting technique scheme, the insulation muscle that is uniformly distributed in skeleton tubulose outer peripheral face is located between the main leaf of adjacent pole piece, and main leaf is equated with distance between the main leaf, makes symmetry reach best, thus the increase motor stabilizing.
The utility model further is set to: described shirt rim is provided with slot between the insulation muscle, described slot and main leaf are suitable near a side of shirt rim, also are provided with the draw-in groove suitable with leg on the described shirt rim, and described draw-in groove and slot link.
By adopting technique scheme, slot better is arranged between the insulation muscle main leaf, further optimizes the symmetry between main leaf, and draw-in groove has then increased the installation stability of pole piece.
The utility model further is set to: described insulation muscle is made by rubber.
By adopting technique scheme, rubber is drawn materials simply, and good insulating is suitable for making the insulation muscle.
The utility model further is set to: described insulation muscle and skeleton are integrated setting, are made of plastics.
By adopting technique scheme, the integral type design makes the cooperation of insulation muscle and skeleton tightr, and the good insulating of plastics is with low cost.
