19th century, developed into Cutting law principles and the use of this principle of special machine tools and gear cutting tools have emerged that military gear plus more comprehensive tool means, the involute but also shows great superiority. Cutting Tools Cutting Just when little movement from the normal engagement position, you can use a standard tool in the machine cut out the corresponding displacement gear. In 1908, Switzerland MAAG displacement method to study the development of a processing and manufacture of non-standard slotting machine shaft parts prices, then the non-standard shaft parts technology, English BSS, USA AGMA, DIN German gear modification have been proposed for a variety of Calculation Method. According shaft parts function and working conditions, the technical requirements, mainly in the following areas: the main shaft parts surface ⑴ dimensional accuracy often into two categories: one is the bearing inner ring with a cylindrical journal, that the supporting shaft Non-standard neck main shaft parts, used to determine the position of the shaft and the bearing shaft, high dimensional accuracy, typically IT 5 ~ IT7; the other for mating with a variety of transmission journal, namely with the journal , its accuracy is slightly lower, often IT6 ~ IT9.
