Gear reducer is a mechanism by which result energy of high-speed motor or engine is transmitted to some other mechanical component by lowering the rotational speed in higher torque. In addition, it delivers mechanical security by Gear Reducers reducing speed of the rotating gear. The number of gears used in the reduction gear assembly depends upon the output velocity and 
requirement of applications.
Increasing set up of wind generators worldwide is driving development of the market
Increasing installation of wind turbines worldwide is one of the main factors driving development of the gear reducer market. Gear reducer is utilized in wind generators for controlling the velocity of engine with which power can be transmitted. The primary reason for gear reducer can be to multiply the amount of torque generated by an input resource, in order to achieve the desired output from the wind turbine. For instance, according to 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 Market Insights’ analysis, the total installed capacities would increase to over dual the installed capacities in 2016, by 2025.
