Torque level 8-10Nm/cm³

D-type high torque three screw gearbox.

D-type high torque three screw gearbox is independently developed by Chuanli's professional gear technology team on the basis of D-type high torque twin-screw gearbox, which adopts parallel three-axis structure design.

Features:

1、High efficiency: The D-type high torque three screw gearbox has high transmission efficiency and can withstand large torque. It is  suitable for parallel co-rotating three screw extruders with high output. 

2、 Long life: The D-type high torque three screw gearbox is made of high strength alloy steel. It has the characteristics of high strength and good toughness, and can maintain good working condition during long-term operation.

3、Shock absorption and noise reduction: The D-type high torque three screw gearbox has a reasonable gear meshing method, smooth operation, and low noise, which can reduce the vibration of mechanical equipment during operation.

Gearbox main body:

1. Professional CNC processing and manufacturing.

2. Made of high quality cast iron material.

3.High-rigidity main body shock-absorbing design.

Gears:

1. Made with high precision gear shaping and grinding machines and high precision and efficient gear hobbing machines, with high processing accuracy and long service life.

2. Material with low carbon alloy steel.

3. Carburizing and quenching process/hardness.

Bearing:

apanese INA, NTN, and NSK bearings are selected with high precision to ensure the safety and stability of the gears.

Plate heat exchanger:

A large-area and efficient plate heat exchanger is selected to ensure that the cooling system of the gearbox is safe and reliable.

Enlarged and thickened lubrication and cooling pipeline design:

1. Enlarging and thickening the pipeline will help reduce the generation of louder noise when the gearbox is running.

2. Flow/temperature/pressure feedback design ensures stable operation of the gearbox.
