Embodiment Construction

[0010] Referring to Figure 1, figure 2 It can be seen that the planar carbon commutator of the present invention includes a commutator segment 1, a molding compound 2, and a carbon block 5, and the body 6 of the commutator segment 1 is perpendicular to the rotation axis (O axis) of the commutator. The segment 1 is arranged in the molding compound 2 and exposes the outer surface of the body 6 of the commutator segment, and the outer surface of the body 6 of the commutator segment is plated with a silver-copper alloy layer 3 (its function is to increase the thickness of the body of the commutator segment). outer surface roughness), the silver-copper alloy layer 3 is coated with a mixed strong adhesive layer 4, and the carbon block 5 is arranged on the mixed strong adhesive layer 4. Wherein, the commutator segment 1 is made of a silver-copper alloy material, the silver-copper alloy layer 3 is formed of a silver-copper alloy that is the same as or similar to the material of the co...

Abstract

The invention discloses a planar carbon commutator for a motor, which comprises a commutator segment (1), a molding compound (2), a carbon block (5), a body (6) of the commutator segment (1), and the commutator The axis of rotation of the commutator is perpendicular, and the commutator segment (1) is arranged in the molding compound (2) and exposes the outer surface of the body (6) of the commutator segment, on the outer surface of the body (6) of the commutator segment The silver-copper alloy layer (3) is coated with a mixed strong adhesive layer (4) on the silver-copper alloy layer (3) and the carbon block (5) is arranged on the mixed strong adhesive layer (4) . The invention solves the problem of complex structure of the existing planar carbon commutator, has the advantages of simple structure and convenient manufacture, thereby saving labor time and reducing production cost, and can fully meet various uses such as motor sparks, noise, and service life performance requirements.

Description

1. Technical field [0001] The invention relates to a commutator for a motor, in particular to a planar carbon commutator. 2. Background technology [0002] Chinese Invention Patent Specification CN 1046598C (authorized announcement date: November 17, 1999, patent number 95102934.7) discloses a planar carbon commutator segment commutator and its manufacturing method, including a base member (which can be called a molding compound), Contact member (can be called commutator piece), carbon commutator piece (can be called carbon block), the base member has a plurality of first containing pockets extending backward from its front end, carbon commutator piece is formed on the contact member and has a direction an integrally formed anchoring device extending rearwardly into said first receiving socket; the anchoring device has an interlocking portion engaged with the rear surface of the contact member to prevent axial disengagement of the anchoring device from the first receiving so...
