A roller bearing replacement device for replacement or exchange of a roller bearing of a roller hearth furnace includes a housing that can be sealed off from the environment or external atmosphere that has a sluice through which access to the roller bearing of the roller hearth furnace that is to be replaced from the inside of the housing while excluding the external atmosphere is possible, and at least one roller bearing handling device that is designed for demounting and installing roller bearings and is arranged moveably in the housing and which can be at least partly moved out of the housing through the sluice. Roller bearing replacement or exchange is possible without the roller bearing getting tilted or twisted through its movement during demounting or assembly as the case may be in the roller hearth furnace. The roller bearing replacement device furthermore has a height adjusting device that is coupled with the housing; this height adjusting device is designed and constructed to position the housing vertically and to align the housing on a horizontal plane.

Roller bearing replacement device

A roller bearing replacement device for replacement or exchange of a roller bearing of a roller hearth furnace includes a housing that can be sealed off against the external atmosphere with a sluice through which it is possible to access to a roller bearing of the roller hearth furnace that is to be demounted from inside the housing while excluding the environmental atmosphere, and at least one roller bearing handling device designed and constructed for demounting and installing roller bearings that is arranged in a moveable manner in the housing and can at least partly be moved out of the housing through the sluice. The sluice has a docking flange and a gas tightness monitoring arrangement, by means of which the gas-tightness of the docking connection on to the roller hearth furnace by the sluice can be monitored.

Roller bearing replacement device and process for switching roller bearings

A roller bearing handling system for replacement or exchange of a roller bearing of a roller hearth furnace includes a base support, a pivot support arranged on the base support, and a first roller bearing handling element arranged or placed on the pivot support and which can lift a roller bearing. The pivot support is arranged on the base support and is able to swivel about a stationary pivot point relative to the base support. A second carrier roller bearing handling element is arranged on the base support for handling a roller bearing and is able to be adjusted between a handling position, in which the second roller bearing handling element can mechanically couple and connect in a form-locking manner with the roller bearing for roller bearing replacement and a release position in which the mechanical coupling and form-locking connection between the roller bearing and the carrier roller bearing handling element is released is released.

A roller bearing replacement device with a housing that is sealed off is provided that has a sluice which can be coupled on a roller hearth furnace through which access to a roller bearing of the roller hearth furnace that is to be demounted is possible, and at least one roller bearing handling device which is arranged in a moveable manner inside the housing and can at least partly be moved out of the housing through the sluice. The housing has a cooling chamber designed for cooling of demounted roller bearings in which the at least one roller bearing handling device is constructed so that it can be moved at least between a replacement position and a cooling position.
