The global market for Industrial Gearbox is projected to reach US$43. 6 billion by 2025, driven by increasing adoption of energy-efficient and high-performance gearboxes. Mechanical power transmission is vital in powering industrial automation equipment. Gearboxes are used to increase torque while reducing speed and deliver power in various combinations of speed and torque. Several types of gearbox designs are popular i. e. helical gearbox; coaxial helical gearbox; bevel helical gearbox; worm reduction gearboxes; planetary gearbox. Bevel & helical type gearbox are preferred in the cement industry, while pinion & planetary gearboxes are preferred in the steel industry which uses heavy, hard wearing machines. The present day gearboxes are capable of processing electric motor power causing minimum mechanical losses through utilization of gear optimization micro-geometries, refined bearing arrangements, superior gear machining methods, as well as advanced lubrication. Such technological developments are widely accepted and vital for providing contemporary power drive solutions. Parallel to this, gearboxes` interfacing with digitized controls use a more refined range of self-diagnostic devices and sensors; enabling an amalgamation among mechanical, information, and electrical technologies. The market for industrial gearbox is driven by increasing adoption of automation across varied industries and applications. Industrial automation is the process of taking control of any equipment or machinery through technology, resulting in improved production output, thereby resulting in cutting down on manpower and labor expenses. This has encouraged companies to adopt AI and robots, so as to manage the manufacturing process. Robots and the automation equipment are being installed across several industries. The integration of industrial gearboxes with the devices will make the automation process more reliable and efficient. While the need for upgrading the old infrastructure with newer technologies in order to efficiently serve the expanding market and to maintain competitive edge continue to fuel the demand for automation technologies, increased labor costs, the sheer shortage of skilled labor, and ageing workforce are consistently prioritizing the automation model in plants and factories. The use of automation helps in improving safety, efficiency and productivity. Automation in material handling also cuts down on operational costs by evading accidents, minimizing time and effort of day-to-day activities, and by eliminating redundancies. Gearboxes are finding increasing use in apron feeders, vibro feeders, paddle feeders, dribble feeders, rotary breakers, stacker belt drive, stacker travel drive, crushers, belt conveyors, reclaimers, etc.
