Product description

Parallel shaft hard tooth surface gear speed reducer is devided into:

ZDY (Single stage); ZLY (Double stage); ZSY (Three stage); ZFY (Four stage)

ZDY type is divided into : 80,100,125,160,200,250,280,315,355,400,450,500,560

ZLY type is divided into: 112,125,140,160,180,200,224,250,280,315,355,400,450, 500,560,630,710

ZSY type is divided into: 160,180,200,224,250,280,315,355,400,450,500,560,630, 710

ZFY type is divided into: 180,200,225,250,280,320,360,400,450,500,560,630,710,800.


1) Small size, light weight, high accuracy, large carrying capacity, high efficiency, long service life, high reliability, transmission smoothly, low noise.

(2) All the gear are made of high quality alloy steel, processe by carburizing and quenching, and the hardness of tooth surface is reach up to hrc54 – 62.

(3) Optimized design for the center distance and nominal transmission ratio. Have good interchangeability for the main parts and components.
(4) Use oil samp to lubricate, natural cooling. When the thermal power is out of the requirement, may use the circulation oil, the fan or the cooling coil to lubricate.


(1) The input speed is generally≤ 1500 r/min.
(2) It can be widely used in metallurgical, mining, chemical, construction, lifting, transportation, textiles, paper making, instruments, plastics, rubber, energy and other industrial field.

(3) The circumferential speed of gear drive is no more than 20 m / s.

(4) The working temperature is – 40~50 ℃, if less than 0℃. Lubricating oil should be preheated more than 0 ℃ before start running. This gear reducer can run reversible.
