Rotary Kiln Drive Gearbox (pix ele6)

Kiln drive main gearbox is developed with a special design incorporating the features of dual tandem system. The gearbox is basically designed with quadruple stage reduction for an absorbed power of 173.22 kW at 1000 RPM having input and output shaft extended on either side with horizontal offset of 1642.40 mm and vertical offset of 280.20 mm, with provision of oil injection holes in the respective shaft for an adjustment of dynamic tooth contact by means of hydraulic pressure. The gear is made from high tensile carburising alloy steel, 17CrNiMob as per DIN 17210, case hardened to 60 +/ 2 HRC, precisely ground to accuracy class B as per DIN 3961 63. The output shaft is made from medium carbon steel CK 60N as per DIN 17200 of adequate size to withstand heavy load transmission for better rigidity without undue deflection. The shaft is supported in anti-friction spherical roller bearings having ample dynamic capacity to give better working life and flexibility against misalignment. Separate motor driven lubrication system is provided to enhance cooling as well as lubrication of bearings and tooth meshes with all necessary control and monitoring devices for pressure, oil flow, oil level, and clogged condition of filter elements.
