Gear box
Transmission gear: Parallel tri-axial structure is combination of reduction and
matrix. The gear is made of high quality alloy (20CrNi2Mo). It had been treated by cementation heat process, the precision
grade can reach6th. It guarantees the tooth surface is high speed,
overloading, low noise and high torque.
Drive bearing: The brand of axletree: Japanese NSK.
Lubrication: Gear bearings in the gear box will be of oil immersed. There is
hydraulic lubrication in the gear engagement and gear bearings.
Cooling: Lubricated cooling adopts shell and tube cooler and circulated
water cooling method.
Screw
Diameter:￠21.7mm

Direction of rotation: Co-rotating
Screw & elements: W6Mo5Cr4V2 (6542#) high speed tool steel that had been treated by the vacuum
hardening process with the hardness of the surface is HRC58-62.Molding through dedicated grinding machine. The cleanliness is
much better than products out of traditional process.
Core axle: High quality alloy steel 40CrNiMo that with high tenacity and durability. It had been treated by the
hardening and tempering process.
Barrel
1). Structure: The first section works for main feeding, and the sixth section is set up for vacuum venting, the others are blocked.
2). Material: The material of the barrel 38CrMoAlA, surface hardness: HV950-1050, depth 0.5-0.7mm 3). Heating: Adopt multiple step format electric heating. All zones are cast
copper heater. The total heating power is 16KW and the max heating capacity every section can reach
500℃.
4). Cooling: Adopt soft water cooling system in the barrel and tap water
cooling way outside barrel. The circulation pipes are made of
stainless steel and the water inflow regulating valves are
stainless valves.
The brand of electromagnetic valve is DANFOSS.
5). Length: 120*7=840mm
