The main journal diameter precision requirements are usually based on the use of IT6 ~ IT9 precision shaft parts wholesale, and even IT5. As for the size requirements are less stringent in the longitudinal direction, usually only provides basic dimensions. 2) the accuracy of the geometry precision geometry refers journal roundness, cylindrical. These errors will affect the quality of their contact with the mating parts. Geometry of the general accuracy of the journal should be limited to within the diameter tolerance range, when high precision geometry to a predetermined shape tolerance on the part drawing. Luoyang Fuyuan Gear Machinery Co., Ltd. specializes in producing bevel gears, shafts, gears, and other precision disc-type shaft parts, please come to order. 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 neck, used to determine the position of the shaft and the support 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 To IT6 ~ IT9.
