Embodiment Construction

[0019] figure 1 A rotary kiln according to the invention is shown in (generally designated with reference number 2 ).

[0020] The rotary kiln 2 consists of a combustion chamber 4 and a drive 6 .

[0021] The combustion chamber 4 is generally cylindrical and mounted for example to be rotatable about an axis of rotation X-X in a support not shown.

[0022] The drive means 6 are able to drive the combustion chamber 4 in order to rotate the combustion chamber 4 about the axis of rotation X-X.

[0023] The drive device 6 consists of a drive ring gear 8 . A ring gear 8 surrounds the combustion chamber 4 and is attached for rotation about the combustion chamber 4 .

[0024] The driving device 6 also includes a driving motor 10 and a gear reducer 12, the gear reducer 12 is provided with a driving pinion 14, and the driving pinion 14 is an output pinion of the gear reducer. The drive pinion 14 meshes with the drive ring gear 8 . The gear reducer 12 is driven by the drive motor 10...

Abstract

This drive device (6) is capable of transmitting a drive torque to the combustion chamber of a rotary kiln. The drive device (6) includes a drive ring gear (8) adapted so as to be attached to the combustion chamber. At least a portion of the drive ring gear (8) is fabricated out of cast iron.

Description

technical field [0001] The invention relates to a drive arrangement for transmitting a drive torque to a combustion chamber of a rotary kiln, said drive arrangement comprising a drive ring gear adapted to be attached to the combustion chamber. Background technique [0002] A drive of this type is already known from document WO 2010 / 67183. [0003] Traditionally, the drive ring gears for the combustion chambers of rotary kilns are manufactured from steel. In the particular case of rotary kilns, so far no material other than steel has been considered capable of stopping the rotary kiln during heating which causes specific difficulties and can lead to failure of the combustion chamber. The resistance of steel is therefore considered sufficient to provide the necessary reliability. [0004] However, steel is expensive and making ring gears from steel is difficult. Contents of the invention [0005] It is an object of the present invention to provide a drive for a rotary kil...
