Abstract

A puller resetting device on a shifting bearing block of a twin roller caster comprises a support seat fixed on a bottom plate of a casting roller set of the twin roller caster by a bolt. Three shaftsleeve installation holes are arranged on a support plate of the support seat and are respectively provided with a shaft sleeve with an internal thread. The shaft sleeves are fixed on the support plate of the support seat by nuts. Each shaft sleeve is connected with an elastic puller device by a thread. The elastic puller device comprises a casing with one end closed and the other end opened. Thecasing is provided with a disk spring and a mandril inside. An external thread is processed on the excircle of the mandril and is connected with the internal thread of the shaft sleeve. A plane bearing is arranged on a round table at one end of the mandril and is fixed on the round table by a plane gland nut which is put against the disk spring in the casing.
