Example Embodiment

[0030]figure 1 It shows a partial cross section of a commutator 10, whose copper section 26 is cast or embedded in the plastic 12 and can rotate around the axis of rotation 14 when the commutator 10 is in operation.

[0031] In order to improve the torsional strength, the commutator 10 is provided with a reinforcing ring 16 on at least one end surface, preferably on both end surfaces, which is composed of a metal ring 18 and an insulating ring 20. The reinforcement ring 16 is mounted in a mounting seat 15 in the copper section 26. In this embodiment, the mounting seat 15 is designed to be groove-shaped and is composed of cuts in each copper section 26. Although there are various implementation forms for this type of insulating ring, the glass fiber ring 20 is preferably used as the insulating ring.

[0032] The copper section 26 has a holding core 28 on the side facing the rotation axis 14, which forms a part of the mounting seat 15 of the reinforcing ring 16.

Abstract

The invention concerns a commutator with a reinforcing system comprising a stepped insulating ring with a carrier part and a flange part and a metal ring which has a rectangular cross-section and is fitted into the stepped shape of the insulating ring such that part of the radial outer surface of the metal ring abuts the radial inner surface of the flange part and the end inner surface of the metal ring completely abuts the end outer surface of the carrier part.

Description

technical field [0001] The invention relates to a commutator with copper segments embedded in plastic, the copper segments are fitted into at least one mounting seat into a reinforcement ring coaxially arranged on the commutator axis of rotation, which consists of a metal ring and a Composed of insulating rings combined with metal rings. Furthermore, the invention relates to a method of manufacturing said commutator, according to which a body consisting of copper segments is made with at least one seat for a reinforcing ring consisting of a metal ring and an insulating ring ; install the reinforcing ring on the mounting seat; and, then cast the commutator with plastic. Background technique [0002] Different commutator embodiments are known, all of which are reinforced with glass fiber reinforcement rings. Although these commutators have outstanding advantages, such as fiberglass rings have favorable expansion characteristics and can be preloaded ...
