DFY hardened gear reducer 

DFY hardened gear reducer is suitable for transmission devices with vertically arranged output and input shafts. It is mainly used in various transportation machinery such as belt conveyors, and can also be used in the transmission mechanism of various general machinery such as metallurgy, mining, construction, cement, light industry, energy, etc.

Hardened gear reducers mainly include parallel shaft series and vertical shaft series, which mainly include four series: ZDY (single stage), ZLY (two stages), ZSY (three stages) and ZFY (four stages). Vertical shaft reducers are produced according to national standards (JB/T9002-1999). They are used for transmission devices with vertical arrangement of input shaft and output shaft, which mainly include three series: DBY, DCY and DFY.

DFY hardened gear reducer performance characteristics (1) The main parameters such as center distance and nominal transmission ratio are optimized and designed, and the main parts and components have good interchangeability.

(2) The gears are made of high-quality alloy steel through carburizing and quenching, and the tooth surface hardness reaches 54-62HRC.

(3) Small size, light weight, high precision, large load-bearing capacity, high efficiency, long life, high reliability, smooth transmission and low noise

(4) Generally, oil pool lubrication and natural cooling are used. When the thermal power cannot be met, circulating oil lubrication or fan and cooling coil cooling can be used.
