Reversing sheet, reverser manufactured by reversing sheet and manufacturing process of reverser

Abstract

The invention relates to an improvement on a reversing sheet and a reverser manufactured by the reversing sheet and further relates to an improvement on the manufacturing process of the reverser. The reversing sheet comprises a main body and a root part, and is characterized in that bulges are transversely arranged on the left side and the right side of the main body; the reverser manufactured by the reversing sheet comprises mould plastic and the reversing sheets; the reversing sheets are embedded into the mould plastic and are arranged into a circle; the reverser manufactured by the reversing sheet is characterized in that the bulges on one side of each of the adjacent reversing sheets are adhered to one another; the mould plastic stretches between the reversing sheets and the main bodies; a space formed by the bulges between the two main bodies is filled with bakelite powder (namely mould plastic). The bakelite powder replaces conventional mica sheets to achieve an insulating effect, so that the labor is saved, the production efficiency is improved and the production cost is reduced; and the manufacturing process of the reverser is simpler.

Description

technical field [0001] The invention relates to an improved invention of a commutator segment and a commutator made by using the commutator segment, and also relates to an improved invention of a method for manufacturing the commutator. Background technique [0002] At present, the surface of the main part of the commutator segments on the common commutator on the market is flat. When making the commutator, the commutator segments are arranged in a circle with a gap through the process circle, and then a piece is artificially placed within the gap. Insert the mica sheets one by one, put the commutating piece set with the mica piece inserted on the fixing ring, knock out the process ring, and then put the commutating piece set on the mold through the fixing ring, and then inject the commutator. The prototype, the production process is cumbersome, and the mica chips are manually inserted by hand, which is a waste of manpower and financial resources, and affects the production ...

[0002] At present, the surface of the main part of the commutator segments on the common commutator on the market is flat. When making the commutator, the commutator segments are arranged in a circular shape with intervals through the process circle, and then a piece is artificially placed within the interval. Insert the mica piece one by one, put the inserted mica piece into the fixed ring, knock out the process circle, then put the commutator piece into the mold through the fixed ring, and then inject molding, this will form the commutator The prototype, the production process is cumbersome, and the mica sheet is manually inserted, which is a waste of manpower and financial resources, and affects the production efficiency of the product
