TRANSFER EQUIPMENT FOR TRAY IN LOW PRESSURE CARBURIZING FURNACE

A transfer equipment that can perform loading and unloading operations through one door while maintaining vacuum of a batch type carburization furnace in which vacuum conditions of high temperature and lower pressure are maintained and can transfer a carburization tray silently by directly driving rollers through drive gear units attached to one sides of the rollers is provided. In a cerburization tray transfer equipment installed within a vacuum carburizing furnace, the cerburization tray transfer equipment comprising a furnace body external casing(1), an internal insulation casing(2) and drive gear units(5), an equipment for transferring a carburization tray in the vacuum carburizing furnace is characterized in that: rotation shafts(4) made of graphite and installed at one sides of rollers(3) are connected to rotary power transmitting universal joints(33) outside the internal insulation casing through small shaft passing holes formed on the internal insulation casing; the rotation shafts are connected to rotation shafts installed at the drive gear units by the universal joints; spur gears are mounted on the drive gear units installed between the internal insulation casing and the furnace body external casing; idle gears are mounted under the spur gears to transmit power to front and rear rollers in the same direction; and ends of the spur gears are connected to universal joints(6) to rotate the rollers in a predetermined direction.
