While it is certainly true that the "setting" or "laying out" of a pair of bevel gears is more complicated than laying out a pair of spur gears, it is also true that following the correct procedure
WhatsApp: +86 18838072829The gear engineer should design bevel gears with an offset whenever possible— especially small offsets that achieve the desired advantages without the potential disadvantages that the hypoid offset can produce. Even a very small offset helps to avoid pitting population along the pitch line, as they are known in spiral bevel gears.
