Low-Noise Grinding Bevel Gears with Extra-Long Shaft for Efficient Transmission
This precision-grinding orthogonal gear set with an extra-long integral shaft is engineered for high-performance industrial drive systems that require exceptional accuracy, stability, and durability. Manufactured with advanced grinding technology and produced under ISO 17485:2006-6 standards, the gear set delivers superior meshing quality, reduced noise, and high transmission efficiency—making it suitable for demanding machinery applications.
This gear assembly consists of a spiral bevel gear pair (Z = 44:11, Modulus 3M) combined with a one-piece extended shaft. The integrated design eliminates joint weaknesses and ensures excellent coaxiality, making the product ideal for long-distance torque transmission and high-speed operation.
The ground tooth surfaces significantly enhance precision and reduce backlash, while the optimized geometry enables smooth, quiet, and efficient power transfer even under heavy loads.
Low-Noise Grinding Bevel Gears with Extra-Long Shaft Product Structure Description
● Bevel Gear
Precision-ground tooth surfaces ensure high tooth profile consistency.
Gear Ratio: Z = 44 : 11
Module: 3M
Suitable for medium-to-high speed and high-torque orthogonal transmission structures.
● Extra-Long Integral Shaft
