Rock Drilling Machine Axle Shaft Assembly Corrosion Resistance Universal Joint Drive Shaft
The rock drill wheel-end axle assembly is a core transmission component for drilling equipment in mining, tunnel construction, and similar applications. Specifically designed to drive the travel and positioning system of rock drills, it efficiently transfers power to the travel wheel set while enduring high-frequency impacts, intense vibrations, and extreme loads in complex geological environments. Its high rigidity, wear resistance, and anti-fatigue design ensure stable movement and precise positioning of the drill in gravel and hard rock terrains, making it a critical component for enhancing drilling efficiency and equipment durability.
- Ultra-High Strength Structure
Made of special alloy steel through integral forging and surface hardening, with hardness reaching HRC 58-62 and tensile strength ≥1,200 MPa. - Fully Sealed Dustproof Design
Composite sealing system (fluororubber lip seal + dust cover) with IP69K protection rating, preventing intrusion of rock dust, mud, and blasting debris. High-temperature grease (operating range: -40°C to 120°C) enables long maintenance intervals. - Compact and Lightweight Design
Structural optimization reduces weight by 25% while maintaining torque capacity ≥50,000 N*m, meeting agile steering requirements in narrow mine tunnels.
