| Popis: | 93 Hobbing is one of the most efficient and economic ways to produce spur and helical gears. Besides the setting of the hobbing machine, the geometric parameters of the hob and the feeds of the hobbing machine greatly effects the precision of the hobbed gear. This thesis aims to set up mathematical model for the cutting edge of multi-start hob and the surface topology of the hobbed gear. By varying the geometric parameters of the hob and the hobbing feeds, the precision and the surface roughness of the hobbed gear are investigated. The results of this thesis can be used to simulate the cutting mark on the toothsurface of the hobbed gear and calculate the tooth flank precision of the hobbed gear. |
