Abstract
The utility model discloses a commutator segment is personally experienced sth. Part of the body and is fixed the foot by the main leaf and constitutes, and the side is the centrosymmetric inclined plane about the main leaf body, and the inclined plane contained angle is 15 degrees, its characterized in that: the lateral surface of the main leaf body is the plane. The utility model discloses the position control of circumference direction is easily realized to row's piece in -process in the mould bucket, makes the mica sheet of singly inserting between commutator segment can easilier adopt same thickness, improves convenient assembling nature, can save commutator segment materials, reduce cost simultaneously.
Description
Technical field
The utility model relates to commutator topology field, is specifically related to a kind of improvement invention of commutator segment.
Background technology
Commutator product mainly divides Hooked reverser, tank commutator and end commutator three kinds.The conventional construction of the commutator segment of Hooked reverser and tank commutator is: be made up of main leaf body and fixing feet, inclined-plane symmetrical centered by the left and right side of main leaf body, inclined-plane angle designs according to the commutation blade number of commutator, and the lateral surface of main leaf body is the arc surface of coupling commutator cylindrical.The commutator segment of above-mentioned conventional construction, when needing to be insulated by mica sheet when between sheet, this list just needing commutator segment to carry out mica sheet during screening in mould bucket is inserted, because the lateral surface of commutator segment is arc surface and the height of arc surface point contacts with the circular-hole internal-wall of mould bucket, so the position of the circumferential direction of commutator segment in mould bucket not easily regulates, certainly dimensional discrepancy is there is in the commutator segment simultaneously owing to making on thickness, so between sheet during single slotting mica sheet, mica sheet will adjust thickness in good time, make single mica sheet inserted substantially can not adopt same thickness, which adds assembly difficulty, operating efficiency also can be affected.
Summary of the invention
In view of the deficiency of background technology, the purpose of this utility model aims to provide the position adjustments being easy to realize circumferential direction in a kind of screening process in mould bucket, enable single mica sheet of inserting more easily adopt same thickness, improve property easy to assembly, the commutator segment simultaneously save materials, reducing costs.
The utility model takes following technical scheme:
Commutator segment, is made up of main leaf body and fixing feet, and inclined-plane symmetrical centered by the left and right side of main leaf body, inclined-plane angle is 15 degree, it is characterized in that: the lateral surface of main leaf body is plane.
Described fixing feet is the bar shaped lath being parallel to main leaf body setting, and bar shaped lath is connected with the medial surface of main leaf body by floor, and the middle of floor is provided with a square fenestra.
Adopt the commutator segment of technique scheme, the lateral surface of its main leaf body is designed to plane, the lateral surface of such commutator segment just contacts with the circular-hole internal-wall of mould bucket less than arc surface height point, thus make the position of the circumferential direction of commutator segment in mould bucket be easy to realize regulating, so between sheet during single slotting mica sheet, mica sheet can adopt the same thickness calculated substantially, which improves the convenience of assembling, simultaneously, owing to eliminating arc surface, this part material of arc surface just can save, and reduces costs.Secondly, the design of square fenestra enables commutator segment enter into square fenestra fully filling with phenolic moulding powder during phenolic moulding powder injection-compression molding, makes to be formed between commutator segment firmly to combine, improves the mechanical strength of commutator product.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is side surface direction view of the present utility model,
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in the figure, commutator segment of the present utility model, is made up of main leaf body 1 and fixing feet, and inclined-plane symmetrical centered by the left and right side 12 of main leaf body 1, inclined-plane angle is 15 degree, and the lateral surface 11 of main leaf body 1 is plane.Described fixing feet is the bar shaped lath 2 being parallel to main leaf body 1 setting, and bar shaped lath 2 is connected by the medial surface of floor 3 with main leaf body 1, and the middle of floor 3 is provided with a square fenestra 4.
