The present invention provides a core ring assembly for an elevator governor, a governor and an elevator system, wherein the core ring assembly comprises: a first portion and a second portion of a core ring which are axially arranged, the first portion and the second portion of the core ring having contact surfaces therebetween; and a pressure generation mechanism for generating a pressure between the first portion and the second portion of the core ring, wherein the first portion of the core ring rotates by receiving an actuation torque from an over-speed actuating mechanism, and the second portion of the core ring rotates with the first portion of the core ring by virtue of friction of the contact surfaces and enables a safety activating module. The core ring assembly provided by the embodiment of the present invention has a peak torque limiting function and a compact structure.
