This standard contains information for the design@ fabrication@ inspection and mounting of bevel gears. The term bevel gears is used to mean straight@ spiral@ zerol bevel and hypoid gear designs. If the text pertains to one or more but not all@ the specific forms are identified. The manufacturing process of forming the desired tooth form is not intended to imply any specific process@ but rather to be general in nature and applicable to all methods of manufacture. Precision finish@ as used in this standard@ refers to a machine finishing operation which includes grinding@ skiving@ and hard cut finishing. However@ the common form of finishing known as lapping is specifically excluded as a form of precision finishing. Users should determine the cutting methods available from their gear manufacturer prior to proceeding. Cutting systems used by bevel gear manufacturers are heavily dependent upon the type of machine tool that will be used. This standard is intended for use by an experienced gear designer capable of selecting reasonable values for the factors based on his knowledge and background. It is not intended for use by the engineering public at large.
