The worm rolling gearbox specially built for ORT Italia provides maximum stability of part diameter and straightness for the rolling of large diameter, high hardness and precision threads while maintaining a fixed centerline allowing for simplified tooling design.

This gearboxes are equipped with high precision and optimally designed spur and helical gearbox combinations with a 4 speed shifter mechanism for adjusting the feed and torque. Also these gearboxes come with a pneumatically actuated clutch for engaging and disengaging one roller die. This high performance infeed & thru feed two die cylindrical worm rolling gearbox is typically used in worm rolling machines to produce precision thread forms on Worm Shafts, rock drill shafts, gas compressor rods, jack screws, lead screws & other similar products that require a precision thread roller to meet their needs. These gearboxes can also be connected to NC control through an encoder arrangement allowing real time monitoring for process control.

In sum, the designed gearbox is simple and compact for its structure to suit in the thread rolling machine. Its transmission efficiency is high with high torque transmitting capacity

this stable drive proves to be reliable with its unique features. This series of gearbox is designed for its long working life with an aim to reduce the frequent breakdown and maintenance.

We consider ourselves grateful for ORT Italia to provide us this opportunity to develop these gearboxes for their thread Rolling Machines.
