Influence of Gear Design on Tool Load in Bevel Gear Cutting Fritz Klocke, Markus Brumm, Stefan Herzhoff Abstract During gear design,
2、the tooth geometry is optimized towards the required running behavior. Pressure angle and tooth root radius of the gearset are among the influencing factors. As the tools in bevel gear cutting are specially designed for each gearset, the tool profile geometry is defined by the gear geometry. The obj
3、ective of this work is to analyze the influence of the tool profile geometry on thermal and mechanical tool load during bevel gear machining. By means of a finite element based machining simulation the chip formation in bevel gear cutting of ring gears is calculated. The simulation results show a si
4、gnificant thermal and mechanical load maximum at the tool corner, where the maximal wear occurs. The variation of the tool profile geometry shows a high influence of the tool pressure angle and the tool corner radius on the tool load at the tool corner.

5、ing Simulation, Tool Temperature, Tool Stress, Wear 1. Introduction and Challenge Bevel gear cutting is a very productive machining process, especially in automotive applications. A ma- chine kinematic in six axes is necessary to manufacture the gear geometry. In typical applications, the unde- form
6、ed chip cross-section is L-shaped, spreading over two adjacent cutting edges including the tool corner as shown in Fig. 1. Fig. 1 Multi-Flank Chip Formation in Bevel Gear Cutting In this multi-flank chip formation tools often reach the tool life due to excessive wear at the tool corner radius 1, 2, 3, 4. This local wear limits the usable tool life in series production. Furthermore, tool wear related problems cannot be considered during the design phase of bevel gears. This would requir
