Gear reducer is a system by which output energy of high-speed motor or engine is transmitted to some other mechanical component by 
lowering the rotational speed at higher torque. In addition, it delivers mechanical safety by reducing rate of the rotating equipment. The number of gears found in the reduction equipment assembly depends on the output rate and dependence on applications.
Increasing installation of wind generators worldwide is Gear Reducers driving development of the market
Increasing set up of wind generators worldwide is one of the major factors driving growth of the apparatus reducer market. Gear reducer is used in wind generators for controlling the speed of engine with which power can be transmitted. The primary reason for gear reducer can be to multiply the quantity of torque generated by an input reference, to be able to achieve the desired result from the wind mill. For instance, based on the Global Wind Energy Council (GWEC), in 2016, the total set up capacities of wind turbine was 485 GW and is expected to surpass 800 GW by 2021. According to Coherent Marketplace Insights’ analysis, the full total set up capacities would increase to over double the installed capacities in 2016, by 2025.
