Hansen P4 Single Stage Gear Units
The Hansen P4 Single Stage gearbox is available in 9 different sizes, with up to 170,000 Nm torque output and with a power rating of up to 10,500kW. To complement the Hansen P4 Multistage gear units, Hansen has introduced a brand-new and innovative range of single stage gear units, suitable for various applications requiring small reduction ratios, such as paper machines, pumps, compressors, etc.
Features of P4 Single Stage Units
• New, heavy duty single stage gear units extend into the multi megawatt power range
• High torque geometry in low speed gear sets
• Low noise geometry in high speed gear sets
• Dedicated housings for single stage applications
• Enlarged, monoblock or split housing and increased shaft height for higher thermal ratings
• Housing can accomodate gear sets with different center distances
• The rounded housing design features a smooth surface to minimize dirt or moisture accumulation
• Oversized inspection cover
• Balance between mechanical, thermal and bearing rating for all ratios results in a new and more logic approach of size selection
• Two housing mounting positions, horizontal and upright
• Our Oil-LockTM system is standard sealing for high speed shaft
• Tapered roller bearings fitted into a rigid housing absorb the high internal gear forces
• Options for improved protection such as labyrinth sealing, anti-dust or anti-moisture breather
