Gear Box Elements
The HUMBER split-transmitting principle has been successfully implemented in the HUMBER gearbox. With the digital online monitoring system, each gearbox is assembled with precision positioning for torque balance. The gearboxes are manufactured for HUMBER using CNC machine tools. Each gearbox is guaranteed by HUMBER itself. The specific torque factor is up to 10.3Nm/cm3, which features the gearbox properties in a twin-screw extruder. Higher factor means transmitting greater output force to the screws,
Overload Protection
 Torque limiter the overload protection torque limiter applied for instant protection for gearbox and extrusion units. This will be helpful for sudden surges in mechanical load. Precise speed difference sensors and control panel. There are two sensors between the motor side and gearbox side that will transfer a digital signal to the control system once any readable speed difference occurs. Electrical overload protection of the main drive motor is also incorporated.
