Abstract
The utility model discloses a kind of direct current torque motor commutator segment joinery and its constructions, including commutator segment, groove surface, salient point surface, top-surface camber, lower groove face, it is characterized in that the main body that the commutator segment is, groove surface is equipped on the left of the commutator segment, salient point surface is equipped on the right side of commutator segment, it is equipped with top-surface camber on the upside of commutator segment, is equipped with lower groove face on the downside of commutator segment.Such joinery and its construction commutator segment is suitable for the torque motor so big group, and is directly verified, uses in production.
Description
Technical field
The utility model relates to torque motor commutator segment field, specially a kind of direct current torque motor commutator segment Tenon knot
Structure.
Background technique
Traditional commutator segment is mutually limited by commutator segment two sides, and by control commutation chip size, commutation chip size must not
Excessive or too small, excessive last several groups are changed piece and insert not enter, and the too small direct spacing of commutator segment is too big, and slot is too wide, and is easy to incline
Tiltedly.The type commutator segment only leans on two sides mutually to limit, and each commutator segment is independent between each other, and commutator segment is easy to incline when insertion
Tiltedly, and between each commutator segment being distributed is not especially uniformly, some, which change between piece to be easy to be mutually inclined, causes bottom to be touched together
Or bottom spacing is too small leads to commutator segment direct short-circuit.When electric motor winding end is larger, when shaping, is also easy to individual commutator segments
It squeezes outward, individual commutator segments is caused to be inclined outwardly.Therefore it is big to be easy to appear two commutator segment spacing in process of production, between two commutator segments
Away from too small or even encounter together, commutator segment is inclined outwardly, whole non-round.When leading to following process cutting at present some spacing compared with
Greatly, side insulating layer quarter is not fallen, and directly affects motor service performance, and it is too small that some change piece spacing, and carbon dust is easy when motor works
Accumulation short circuit influences motor use, and commutator segment, which contacts with each other, directly results in winding short circuit, scrap of the product, outside individual commutator segment pictures
Tilt it is excessive cause when Vehicle Processing commutator segment effective thickness smaller or direct vehicle falls, make scrap of the product.Increase especially as motor
Greatly, when commutator segment the piece number increases, it is more easier that above some phenomenons occur.Using tradition commutation chip architecture, whole process
Efficiency is lower, and quality controllability is not strong, and qualification rate is not high.
Utility model content
The utility model is exactly in view of the above problems, provide a kind of direct current torque motor commutator segment joinery and its construction.
The utility model achieves the above object through the following technical schemes:
A kind of direct current torque motor commutator segment joinery and its construction, including commutator segment, groove surface, salient point surface, top-surface camber, lower slot
Face, it is characterised in that the main body that the commutator segment is, the commutator segment left side are equipped with groove surface, are equipped with salient point on the right side of commutator segment
Face, commutator segment upside are equipped with top-surface camber, are equipped with lower groove face on the downside of commutator segment.
Further, the length and width of the groove surface and salient point surface is worked in coordination.
Further, six turnings on the lower groove face are set as arc chord angle.
Further, the arc surface of the top-surface camber and lower groove face is on concentric circles.
The utility model maximum feature is so that each commutator segment mutually limited, be mutually located using joinery and its construction, is entirely become
Phenomena such as one, for commutator segment joinery and its construction without single commutator segment tilt phenomenon, spacing is big, short-circuit, between each commutator segment mutually
Limitation, forms full circle, and arrangement is uniform, it is not necessary to which secondary reshaping improves production efficiency, and overcomes the arrangement of traditional structure commutator segment not
Uniformly, the bad disadvantage of whole circularity.And such joinery and its construction commutator segment is suitable for the torque motor so big group, and straight
It connects and is verified, uses in production.
Detailed description of the invention
Fig. 1 is utility model diagram,
Fig. 2 is traditional commutator segment schematic diagram:
1-commutator segment, 2-groove surfaces, 3-salient point surfaces, 4-top-surface cambers, 5-lower groove faces.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of direct current torque motor commutator segment joinery and its construction, including commutator segment 1, groove surface 2, salient point surface 3, top-surface camber 4, under
Groove face 5, it is characterised in that the main body that the commutator segment 1 is is equipped with groove surface 2 on the left of the commutator segment 1, sets on the right side of commutator segment 1
There is salient point surface 3, top-surface camber 4 is equipped on the upside of commutator segment 1, is equipped with lower groove face 5 on the downside of commutator segment 1.
Further, the length and width of the groove surface 2 and salient point surface 3 is worked in coordination.
Further, six turnings on the lower groove face 5 are set as arc chord angle.
Further, the top-surface camber 4 is with the arc surface of lower groove face 5 on concentric circles.
The utility model maximum feature is so that each commutator segment mutually limited, be mutually located using joinery and its construction, is entirely become
Phenomena such as one, for commutator segment joinery and its construction without single commutator segment tilt phenomenon, spacing is big, short-circuit, between each commutator segment mutually
Limitation, forms full circle, and arrangement is uniform, it is not necessary to which secondary reshaping improves production efficiency, and overcomes the arrangement of traditional structure commutator segment not
Uniformly, the bad disadvantage of whole circularity.And such joinery and its construction commutator segment is suitable for the torque motor so big group, and straight
It connects and is verified, uses in production.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
