Transmission Shaft PT08055200 is a critical power transmission core component exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground hard rock drill power systems, high-load quarry drill drive assemblies, and coastal mining sites with humid air.
These settings pose severe challenges for drill transmission shafts: extreme torsion (up to 5000N·m) from power transfer, intense vibration (35G) from rock drilling impact, abrasive rock dust, corrosive mining slurry, and temperature fluctuations. These issues often cause shaft fatigue cracking, wear, corrosion, or torsion failure, leading to drill power system breakdown and costly downtime. Yet, Transmission Shaft PT08055200 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its 40CrNiMo alloy steel base + quenched & tempered treatment achieves 1100MPa tensile strength and 5000N·m torsion resistance, withstanding extreme power transfer loads without deformation or rupture. This extends service life by 170% compared to standard 45# steel transmission shafts. Second, the nitrided surface (80μm thickness) reaches HRC 58-62 hardness, resisting wear from spline engagement and rock dust abrasion. Consequently, it reduces surface scuffing and ensures smooth power transmission for long-term use. Third, the precision spline design (±0.01mm tooth tolerance) ensures tight meshing with drill motor/gearbox components, eliminating power loss during transmission. Likewise, this improves drill energy efficiency by 20%.
Fourth, the anti-corrosion nitrided layer + epoxy coating resists rust and chemical erosion from mining slurry, passing 720-hour salt spray tests with no degradation. Above all, this ensures reliability in coastal or underground mines with high humidity. Fifth, the wide temperature adaptability (-40°C~120°C) ensures stable performance in freezing high-altitude mines and hot drill power compartments. On top of that, the balanced dynamic design reduces vibration by 30% during operation, protecting adjacent gearbox and motor components from impact damage.
Unlike ordinary industrial transmission shafts, this model is engineered for Hydraulic Rock Drills’ high-torsion needs. To elaborate, the 40CrNiMo alloy steel targets extreme power transfer loads, while the precision spline design adapts to drill gear engagement—features tailored to mining operational demands. Thus, it outperforms generic shafts in service life by 180%, significantly reducing maintenance costs.
Our manufacturing team uses precision CNC spline machining + quenching & tempering + nitriding technology for the transmission shaft. Furthermore, each unit undergoes torsion testing (5000N·m) and dimensional verification (±0.01mm tooth tolerance). Additionally, the shaft undergoes 100,000-cycle fatigue trials to ensure no performance degradation.
Notably, it operates stably in temperatures from -40°C (Arctic mining regions) to 120°C (drill power transmission systems). Moreover, the nitrided surface endures 6,000-hour wear trials without excessive material loss. In addition, the 40CrNiMo steel core resists fatigue cracking even under continuous high-torsion operation.
The transmission shaft’s flange + spline connection design integrates seamlessly with mainstream Hydraulic Rock Drill power systems. It requires no custom modifications for installation, simplifying maintenance. As a result, maintenance teams can complete replacement in 45 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform torsion resistance tests, precision inspections, wear resistance trials and corrosion verification. Importantly, it complies with ISO 6336 international mechanical transmission shaft standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces transmission shaft-related failure rates by 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only ensures efficient power transmission for drill systems but also extends the service life of drill power assemblies by 90%. Overall, Transmission Shaft PT08055200 delivers cost-effective, high-performance results for long-term mining operations. Beyond that, it minimizes downtime caused by shaft failure, maximizing operational efficiency and project profitability.
