THE BEVEL GEARS MACHINING
This study aims to present the bevel gears processing method. The
first part presents the theoretical aspects of the bevel gear. The second part
presents the effective method of their generation.
The theoretical study of bevel gears is very complex. The principle of
generating a bevel gear is represented by the generating of plane gear teeth
profile through a cutting tools system and then meshing between bevel gear
and plane gear during machining.
Taking into consideration the complexity of the bevel gears
processing, we do not claim that this study has exhaustively analyzed all the
aspects of this subject.
Keywords: bevel gear, plane gear, meshing

30-24 CALCULUL DE PREDIMENSIONARE AL ANGRENAJELOR CONICE

THE ROUGH SIZING CALCULATION OF THE BEVEL GEARS
This study aims to present the rough sizing calculation of the bevel
gear. In this study are presented the bevel gears type Klingelnberg.
The calculation has the purpose of determining the main elements of
the bevel gears: the minimum diameter of the pinion, the number of teeth for
the pinion and for the gear wheel, z1 and z2, the mean normal module mn, the
face width B and the mean spiral angle βm.
The final geometry calculation of the bevel gear Cyclo Palloid
Klingelnberg according to ISO 23509:2006 will be made using special
calculation program for machine design.
Keywords: bevel gear, pinion, mean spiral angle, face width
