[0003] The spiral bevel gear of big specification needs a large amount of lubricating oil during the running-in period, but the lubricating oil is mainly poured at the intersection of the teeth, and the lubricating oil will gradually volatilize or solidify for a long time. Unlike the conventional spiral bevel gear, the spiral bevel gear of big specification needs a higher amount of lubricating oil, and the pouring interval is short, so that the use amount of lubricating oil is high, and the amount of lubricating oil that can directly play a role is also low. Because a lot of lubricating oil will directly flow to the lower part and drip, in order to solve the technical problem, the utility model provides a spiral bevel gear of big specification.
