Abstract

A rotor assembling method for a turbo-charger may include washing and preparing components of a rotor having a connector, a permanent magnet, end caps, a retention ring, and a center pipe, inserting the connector into the permanent magnet, thermally inserting one or more end caps into the connector by cooling the connector and heating the one or more end caps under a first high-temperature condition for a first predetermined time to form a permanent magnet assembly, thermally inserting the permanent magnet assembly into the retention ring by cooling the permanent magnet assembly and heating the retention ring under a second high-temperature condition for a second predetermined time to form a rotor assembly, thermally inserting the center pipe into the rotor assembly by heating the rotor assembly under a third high-temperature condition for a third predetermined time to form a rotor assembling body, and post processing the rotor assembling body.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0158627 filed on December 31, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a method for assembling a rotor for an electric turbocharger and a rotor assembled by the method, more specifically, to such a method for assembling a rotor for an electric turbocharger and a rotor assembled by the method Rotors, where temperature has less impact on the permanent magnets during hot insertion into the rotor assembly, and are easier to post-machining (such as tip clearance adjustments). Background technique [0004] In general, a turbocharger is a device that rotates a turbine by applying the pressure of exhaust gas discharged from an engine, and then supplies high-pressure air to a combustion chamber by applying the rotational force of the turbine to inc...
