To Take The Advantages Of Gear Modification Into The Large Gear Box Speed Reducer

July 5, 2009 - PRLog -- Modern gears are developed into harden face with high precision, high load capacity, low noise and etc. The gear face modification technology is developed into compensating the deformation of involute under the heavy load. In traditional, the modification technologies are used very few for the difficulties in the manufacture.
With the development of profile grinding technology, to modify the gear profile is very easy under the control of grinding wheel’s profile. But determining the quantity and curve of modification is the key technology, for less or over modification will not satisfy the requirement of gear load capacity even will damage the function of gears.
Based on the special study in the deformation of gear under various heavy load, Ningbo donly transmission has made lots of experiences of modification.
This technology increases the load capacity nearly 20% and lows noise near 3-5dB(A).
Donly has successfully used the technology in the large gearbox gear units gear reduction units speed reducer in large customized gearbox including mill gearbox, turnover gearbox, double helical gearbox, sugar mill gearbox, heavy duty crane gearbox, vertical planetary gearbox in cement and so on.
