gear reducer for plastic extruding   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 bearning is mounted on the front of the output shaft to bear the thrust from the screw.

Applicable scope:

1.The input rotation of prime mover shall be ≤15OOrpm.

2.The peripheral speed of gear drive shall be ≤20m/s.

3.The working ambient temperature shall be within -40°C~45°C. Preheat the lubricatting oil to above 0°C 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. If you want to change the direction, please make detailed description while placing order.
