Camshaft phaser and assembly method therefor

Abstract

The present disclosure relates to a camshaft phaser and assembling method thereof. The camshaft phaser includes an outer front cover, an inner front cover, a spring, a rotor, and a stator. The spring retainer of the outer front cover is substantially cup-shaped and includes a protrusion protruding radially outward from its peripheral wall. The inner front cover includes an inner front cover recess, and the rotor includes a rotor recess. The inner front cover and the rotor are configured so that when viewed axially, a part of the rotor recess is covered by the inner front cover. After the spring retainer is inserted axially into the inner front cover and rotor, the outer front cover rotates under the torque of the spring so that the protrusion of the spring retainer is stopped axially by the inner periphery of the inner front cover.

Dependencies are inferred from the claim text.
