Study on Optimization of Gear Micro-Geometry for Gear Durability
Nowadays, modern gearboxes are characterized by high torque load demands, low running noise and compact design. And the durability of gearbox is specially a major issue for the industry. For gearbox used in roll squeezer, failure can be extremely costly in terms of repair costs, replacement parts, and in lost production due to downtime. The main reasons for gear modification are to compensate for the deformation of the teeth due to load and to ensure a proper meshing to achieve an optimized tooth contact pattern. Typical flank modification may be subdivided into profile and flank modifications. Both modification types are defined separately but can be superimposed. The most common modifications profile and lead crowning are utilized in order to achieve a good contact pattern without having contact on both ends of the flank at either the tip or root area. In order to solve these demands, profile and lead modifications are being applied for gearboxes more often than in the past. In this paper, the gearbox is firstly modeled in Romax software, and then the procedure how to produce profile and lead modifications is expressed. Therefore, comparing with the simulation, there is a good result in the test rig.
