Drive Shaft for Rock Drilling Machine
1.For the main transmission, Gleason spiral bevel gears are used, ensuring high transmission efficiency and effective noise reduction during operation.
2.The planetary reduction structure type "NGW" is applied at the end of the wheel.Its design features compact arrangement and well-thought-out structural configuration.
3.Disc brakes with a caliper are used in the braking system.They provide a large braking torque, ensuring stable and reliable operation of the brakes.
4.Thanks to the integration of the hydraulic steering assist, control becomes smooth and maneuverable.
5.Made from solid cast steel, the axle body demonstrates high load-bearing capacity and high rigidity.
6. Usually installed on 14 - 16-ton drilling machines.
MAIN CHARACTERISTICS:
This equipment, designed for 14-16 ton rock drilling machines, offers superior performance.In the main transmission, Gleason spiral bevel gears are used, ensuring efficient and silent operation, while in the wheel transmission, a planetary design of the NGW type is used, compact and well-thought-out.Disc brakes with a caliper provide sufficient torque for stable stopping, and a hydraulic steering booster ensures smooth maneuvering.The fully cast steel axle body has high load-bearing capacity and rigidity, making it ideal for heavy-duty tasks in drilling rock formations.
