Reducing mechanical work in various industries and performing tasks with less effort is resulting in the increasing use of gears. With the increasing demand for gears, manufacturers are producing gears that are easy to install, reliable, compact and can help in transmitting a huge amount of power. Increasing use of electromechanical machinery and plant automation is resulting in the growing demand for gears. Manufacturers are also working towards developing gears that can withstand heavy loads, leads to low noise emission, and with increased service life. However, the high maintenance cost of gears is one of the major factor hampering the gear demand. Hence, with advancement in technology, companies are focusing on designing gears that produce less heat, and noise, thereby increasing life-cycle of gears.
