Embodiment Construction

[0015] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] Figure 1~Figure 5 Among them, it includes commutator body 1, raised piece 2, waste material 3, protrusion 4, concave platform 5, wire slot 6, etc.

[0017] like Figure 4 , Figure 5 As shown, the present invention is a commutator segment of a DC motor, including a commutator segment body 1 and a riser segment 2, and the cross section of the raw materials for the commutator segment body 1 and the riser segment 2 is trapezoidal, and both commutator The material of silver-copper ladder row T2; The improvement of the present invention is that the reversing segment body 1 and the rising segment 2 are changed into a separate combined structure, and the two are separately blanked and processed. A concave platform 5 is provided on the commutator segment body 1, and a protrusion 4 is provided at the connection part of the rising segment ...

Abstract

The invention relates to a commutator segment of a DC motor, which comprises a commutator segment body and a riser, wherein the commutator segment body and the riser have a split combined structure; the commutator segment body is provided with a concave boss; a part of the riser connected with the commutator segment body is provided with a protrusion; and the protrusion and the concave boss are matched with each other and formed into a whole by welding. An integral structure is changed into the split structure, so materials are saved, the integral strength of the commutator segment is ensured, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a commutator of a direct current motor, in particular to a commutator piece used for the commutator of a direct current motor. Background technique [0002] As one of the main parts of the DC motor, the commutator's strength and performance are very important to the stable operation of the motor. The commutator is assembled from multiple commutator segments. like figure 1 , figure 2 As shown, the commutator segment includes a commutator segment body 1 and a raised segment 2, forming an L-shaped structure. For DC motors that need to cope with frequent impact loads and high speeds, an integral commutator segment is generally used, and the commutator segment body 1 and the lifter segment 2 are integrated and unloaded as a whole. The integral reversing piece has the characteristics of high strength, and the lifting piece 2 is not easily broken and deformed. However, when making and punching this kind of commutator piece, it n...
