ZLYJ reducers are a kind of high-precision rigid gear assembly specially designed for the single-screw

plastic/rubber extruder. Taking the JB/T 8853-2001 Cylindrical Gear Reducer as a reference for design,

the products applies the high-strength low-carbon alloy steel for gears and gear shaft, with tooth flank

carbureted, quenched and ground, to meet the gear precision at Level 6 (GB/T 10095) and hardness of

tooth flank HRC54~62. A huge thrust bearing is mounted on the front of the output shaft to bear the thrust

from the screw.

 

II. Applicable Scope

1. The input rotation of prime mover shall be no less than 1500rpm.

2. The peripheral speed of gear drive shall be no less than 20m/s.

3. The working ambient temperature shall be within -40°C~45°C. Preheat the lubricating oil to above 0°C or

choose the low temperature lubricating oil when the ambient temperature is below 0°C. Rotation is available

both forwards and backwards. However, the high-speed shaft of some types of reducers has a single-way oil

pump directing as defaulted to the output shaft which rotates clockwise
