Detailed Product Description

Rotary kiln Girth Gear Professional Customized High Precision Girth Gears

Bull Gears

Bull Gears can be made available by us as per different international standards including ASTM & AISI (USA), BS (British), JIS (Japanese), GS (German) and IS (Indian) standards. These gears comprise toothed driving wheel which is also largest in the mechanism. As a gear/sprocket much larger than others in same power train, these are larger of two spur gears engaged in any machine.

Features :

Making use of latest computer aided designing support using software like AUTOCAD, SOLID WORKS so as to ensure accurate designing of gears
All software used updated to latest versions
Gears checked for interference checks as well as dimensional accuracies
Expertise in offering solutions as per client's designs and drawings
Expertise in also offering load analysis and stress analysis on gears using finite element analysis for checking appropriate selection of materials & geometrical designs
Reverse engineering and designing support for generating drawings exactly as per sample as well as obtain accurate geometrical sizing

Applications :

Mining industry
Steel plants
Power plants
Paper plants
Fertilizer plants
