results of each calculation step, basic settings are computed as they are commonly used by modern CNC bevel gear generators in order to cut or grind real bevel gearsets. —Hermann J. Stadtfeld.

However, as a precau- tion, high hardness (HRC40 at maximum) occurs in some cases. • For safe handling and to prevent damage such as defor- mation, KHK stock bevel gears have round chamfering at the corners, on the top surface plane of a gear tooth.

helical gears, but the bevel pinion is designed with the larger addendum ( 0.7 working depth). c) This avoids interference and results in stronger pinion teeth. It also increases the contact ratio. d) The gear addendum varies from 1m for a gear ratio of 1, to 0.54 m for ratios of. 6.8 and greater. The gear ratio can be determined

Higher speeds, in. the region of 50 m/s, are possible with high precision ?nished gears. Zerol bevel gears have a tooth form that is curved
