Bearing Holder Roll Removal Tool

Abstract

The utility model relates to a tool for dismantling a roll holding a bearing seat, which belongs to the technical field of mechanical engineering, and in particular relates to a tool for removing a roll holding a bearing seat of a supporting roll of a rolling mill. The invention provides a tool for dismantling a roller holding a bearing seat, which is used for improving the safety of on-site maintenance operation of an oil film bearing. The invention includes a hammer head, a fixed seat, a hinged seat, a lifting block, a connecting beam and an impact hammer, and is characterized in that: the top of the connecting beam is connected with the hinged seat, the bottom is connected with the fixed seat, and the impact hammer is fixed on the fixed seat , the top of the hammer piston is in contact with the hammer head.

Description

Technical field [0001] The invention belongs to the technical field of mechanical engineering, and specifically relates to a tool for disassembling a supporting roller bearing seat of a rolling mill. Background technique [0002] The oil film bearing of the support roll of the rolling mill generates high heat due to an accident. The oil film bearing cone sleeve in the bearing seat is heated and expanded and moves to the side of the roll. After the cone sleeve cools, it will hold the roll tightly, and after the taper sleeve tightly hold the roll The bearing bush and bearing seat are restricted from being disassembled outwards. This kind of bearing seat that holds the roll is often unable to be removed from the roll by a bearing seat disassembly machine. Generally, cranes are commonly used to lift heavy objects at the maintenance site and swing manually. The heavy object hits the bearing seat toward the outside of the roll, so that although the bearing seat can be removed, the hang...

Problems solved by technology

[0002] The oil film bearing of the backup roll of the rolling mill generates high heat due to an accident. The taper sleeve of the oil film bearing in the bearing housing expands and moves to the side of the roll after being heated. The taper sleeve will hold the roll tightly after cooling. Restricting the outward disassembly of the bearing bush and the bearing seat, the bearing seat that tightly hugs the roll is often unable to be disassembled from the roll by a bearing seat dismantling machine. Generally, a crane is used to lift heavy objects at the maintenance site, and manual swing The heavy object hits the bearing seat to the outside of the roll, so that although the bearing seat can be disassembled, there must be room for the hanging part of the impacting object to swing during the operation, but the range near the edge of the bearing seat is narrow, and the swinging track of the impacting object is accurately controlled to hit the impact It is not easy to point, and the suspension as the impact object must be very heavy, so it is possible to damage the bearing seat by impact, and the safety is also low
