【Gear Reducer】ZDY soft tooth surface series gear reducer


Decelerator with hard tooth surface includes parallel shaft and vertical shaft series Parallel shaft decelerator is manufactured according to national standard (JB/T8853-2001)The products are optimized designed to advanced level in national. It includes 4 series of ZDY single stage), ZLY (2-stage),ZSY (3-stage) and ZFY (4-stage). Vertical shaft decelerator is manufactured according to national standard (JB/T9002-1999) and used as driving device that has vertical arrangement of input and output shaft, and it includes 3 series of DBY DCY and DFY.


(1) Preferential desian is applied in main parameter such as center distance and nomina drive ratio, which quarantee good interconnection between key parts and components 

(2) All gears are made of quality alloy steel and treated with carburising and quenching with tooth surface hardness up to 54-62HRC.

(3) Small size, light weight, high precision, large carrying capacity, high efficiency, long service life, high reliability, stable driving, and low noise.

(4) Normally oil sump lubrication is used, with cooling naturally. lf thermal power can not be achieved, circular oil lubrication or fan may be used, and cooled with cooling coil pipe.


(1) Input rotate speed n, is < 1500r/min.

(2) Gear wheel driving peripheral speed is < 20m/sec.

(3) Ambient temperature is -4050 C  f it is < 0C , lubricant should be preheated to> 0C before startup. Runnina both forward and backward are available for this decelerator

(4) Applicable for the industries such as metallurgy, mine, chemical industry, constructior materials,hoisting, transportation,textile, paper making, paper making, food, plastic, rubber, engi neering machinery,and energy industry.
