High-strength reverser reinforcing ring

Abstract

The invention discloses a high-strength reverser reinforcing ring which comprises a reinforcing ring base body formed by alkali-free glass fiber yarns, wherein the reinforcing ring base body is cured by a soaking resin mother solution to form a reinforcing ring body; the resin mother solution is prepared from the following materials: epoxy resin, a curing agent, an organic solvent and powdery insulating solid particles; by weight, the adding quantity of the curing agent is 65 to 75 percent of the adding quantity of the epoxy resin, the adding quantity of the organic solvent is 35 to 50 percent of the adding quantity of the epoxy resin, and the adding quantity of the powdery insulating solid particles is 1 to 3 percent of the adding quantity of the epoxy resin; and at least one part of the powdery insulating solid particles are exposed on the outer surface of the formed reinforcing ring body. Compared with the prior art, the high-strength reverser reinforcing ring disclosed by the invention has the advantages that the integral strength of the reinforcing ring body is greatly improved, and the abrasion resistance of the reinforcing ring body is improved.

Description

technical field [0001] The invention relates to a reinforcement ring, in particular to a high-strength commutator reinforcement ring. Background technique [0002] The commutator is a key component in the manufacture of motors, and the reinforcing ring is an important part of the commutator, which plays a decisive role in the quality of the commutator. [0003] The initial reinforcement ring is made of metal material. Although the reinforcement ring made of metal material increases the tensile strength of the commutator, because it is not insulated, it cannot directly contact the external conductor, and an insulator must be connected. The device can be in contact with the conductor, and after a long time of use, the reinforcing ring made of metal material is easy to cause breakdown and open circuit between the commutator segments, which affects the performance of the commutator. For this reason, someone has developed a reinforcing ring for a commutator made of insulating ma...
