Gearbox for Parallel Co-rotating Twin Screw Extruder

Product Description

Description:

The gearbox reduces the motor speed to the speed ofthe screw shafts and
distributes it to the two output shafts. Screw torque is 1050 N.m per shaft
The gearbox consists of:
Involute gear teeth couplings between the output shafts and screw shafts
Integrated thrust bearing assembly, radial bearings ofthe output axis are NSK products
Bottom part ofcasing designed as oil sump

Technical Parameters:

Each model gearbox is designed with three kinds of ratio 2.5/3/3.75, rotate speed 400/500/600rpm.Take 75 for example.

Model/Item	Main Motor	Reduce ratio	Rotate speed	Torque
Type-75A	90kw	3.75	400rpm	1074.4N.m
Type-75B	110kw	3	500rpm	1050.5N.m
Type-75C	132kw	2.5	600rpm	1050.5N.m

Features of the Gear Box:

1) Reduction Ratio: 3:1
2) Combining host transmission box speed reduction and torque distribution part together, using three axis style design, with compact structure. Speed reduction, torque distribution and two output shaft ridical bearing all use NSK bearings.
3) Input/output shaft oil seal use original Japan brand products.
4) Gear is 6 grade which is a high precision. High speed overloading hard-tooth surface.
5) The bearing and geared are forced to adopted the immersion oil-lubrication system.
6) Framework oil seal use Taiwan brand.

The gearbox reduces the motor speed to the speed of the screw shafts and distributes it to the 2 output shafts.
The gearbox consists of:
?Involute gear teeth couplings between the output shaft and screw shafts.
?Integrated thrust bearing assembly,radial bearings of the output axis are NSK products.
