Abstract

The invention discloses a cold rolled uncoiler drum support roller. The cold rolled uncoiler drum support roller comprises a main shaft, the end portion of the main shaft is provided with an adapter sleeve tapered roller bearing, a roller is assembled outside the adapter sleeve tapered roller bearing, and two ends of the adapter sleeve tapered roller bearing are respectively provided with a gland. The uncoiler drum support roller thoroughly solves the axial movement problem of the drum support roller, reduces the cost and improves the production efficiency.

Description

technical field [0001] The invention belongs to cold-rolled steel strip equipment. It relates to the structural design of the support roll on the reel of the uncoiler. Background technique [0002] Due to the increase in coil weight of modern cold-rolled strip steel, the cantilever decoiler can no longer meet the production needs. Now, the decoiler reel is equipped with backup rolls and external supports. When in use, the tapered roller bearing of the adapter sleeve in the support roller on the reel often moves axially, which increases the deflection of the reel of the uncoiler, and the main shaft is prone to breakage, which seriously affects the performance of the equipment and normal operation. Production. [0003] In order to reduce costs and improve production and quality, modern iron and steel enterprises all use larger tonnage steel coils. The back-up roll structure on the uncoiler reel cannot meet the production needs of strip steel, resulting in frequent downt...
