Abstract
A retainer for securing the compressor rotor (172) to the compressor-turbine shaft (160) of a turbocharger includes a retaining sleeve (180) having an aperture therethrough for mounting the sleeve onto the shaft adjacent the compressor rotor to prevent movement of the rotor on the shaft in the direction of the sleeve. The sleeve has an inner bore (180a) having a diameter forming an interference fit on the shaft such that the sleeve prevents movement of the compressor rotor on the shaft. In one embodiment, a lug (300) extends from the sleeve (180) and engages the compressor rotor to transmit a rotational force from the shaft to the rotor through the sleeve and lug.
