Product Description

Product Overview

Custom manufactured 2-module internal helical gears with 45° helical angle, precision engineered using advanced power skiving technology for superior transmission performance in demanding industrial applications.

Key Features & Benefits

High Transmission Stability: Gradual helical tooth engagement provides larger contact area, reducing shock, vibration, and operating noise
Enhanced Load Capacity: Superior radial and axial load handling compared to spur gears of same specifications
Optimal Space Utilization: Internal engagement design saves radial space while helical configuration optimizes axial dimensions
Improved Efficiency: Smooth engagement process minimizes energy loss for higher transmission efficiency

Industrial Applications

Industrial gearboxes for metallurgical and mining equipment
Automotive drivetrains and planetary gear mechanisms
Construction machinery including excavators and cranes
Aerospace systems requiring high reliability and compact design
