Furnace & Converter Tilt Drives

Typically, David Brown Santasalo furnance and converter tilt drives will have a central bull wheel assembly, which is driven by multiple primary drives that share the load equally to maximise torque.

These gearboxes are often in excess of 100 tonnes, with David Brown Santasalo being one of the few manufacturers worldwide with the necessary facilities and experience to manufacture them.

• Robust fabricated main bull wheel housing, designed using FEA techniques
• Bull wheels can be fabricated or cast
• Primary units have case hardened and ground gears to ISO grade 6 or better
• Motors, breaks and emergency drives can be incorporated into the design and mounted on to the primary units
• Double enveloping worm gear technology for smaller units
• In-house capability to manufacture all major components
• Units can be supplied with integral lubrication systems
• Maximum case rigidity means constant accurate alignment of gears during tilting operation, ensuring reliable operation and long life
• Optimum materials selection giving highest possible overload capacity ratings in minimum space
• Accurate gearing for highest overload capacity, long life and minimised noise and vibration levels
• Whole design optimised for maximum efficiency and overload capability, with one source of supply for the whole unit and no split responsibility
• More teeth in contact at any one time means much higher overload capabilities compared to conventional worm gear solutions
• All critical processes managed using David Brown Santasalo’s quality control systems
• No need for connection to central lubrications systems as gearboxes can be supplied as freestanding units
