They can be described as generally closed, gear systems used to reduce high speeds resulting from drivers such as fixed speed electric motors to revolution speeds required by machines or change the direction of movement. Reducers are structurally power transmission systems consisting of gear systems, gears, shafts, gear bearings as part of power transmission systems placed in body gear box. Although reducers vary depending on gear types they have, Planetary Gear Reducers are commonly used types. The most important reasons for this are smaller inertia moment of rotating masses of planetary gears, their compact structure so they take up less space and capability to work on high speed efficiently. Another important reason is the low gear gaps (low backlash).

Areas of Application

• Automotive
• White Appliances
• Medical products
• Machinery manufacturing
• Food

Reducer Selection
Main factors that determine the type of product to be used are machine's working conditions, heat and the load to be applied to reducer shaft.

• Reducer body type
• Motor power
• Output speed
• Motor connection method
• Load class
• Daily operation hours
• Number of hourly start-stop
• Cycle ratio*

*Number of reducer input speed = Number of engine speed: n1 = nm = 1460 RPM

Number of reducer output speed = Number of construction machinery speed: n2 = niche = 23 d/d

Reducer cycle ratio:  i = n1 / n2 = 1460 / 23 =  63 / 1
