Support roller bearing system of a support roller of a roller hearth furnace, support roller handling device for exchanging support roller and method for exchanging support roller

摘要

In a support roller bearing system (3) of a support roller (2) of a roller hearth furnace (1), comprising a first bearing element (8), a second bearing element (10), a support roller (2) with its first longitudinal end (12) by means of the first bearing element (8) and with its second longitudinal end (13) by means of the second bearing element (10) rotatably in the roller hearth furnace (1) can be stored, wherein from the first longitudinal end (12) of the support roller (2) a shaft journal (14) extends from the from the first bearing element (8) protrudes outwardly and drive-connected with a drive unit (7), a solution is to be created, which are provided in a structurally simple way a storage system, through which the cost of maintenance and replacement of support rollers are reduced can be reduced to a minimum and operational interruptions of the roller hearth furnace. This is achieved in that the first bearing element (8) at least one for handling the support roller (2) serving handling element (40) which is mechanically coupled and positively connected to change a support roller (2) with a support roller handling device (15) to pull out the carrying roller (2) together with the first bearing element (8) from the roller hearth furnace (1) or to introduce the carrying roller (2) together with the first bearing element (8) into the roller hearth furnace (1).
