Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 3852-2008 "Coupling shaft hole and coupling type and size". The main technical changes compared with GB/T 3852-2008 are as follows. --- the table 1 in the Y-type, Z-type and Z1-type shaft hole column content to do the appropriate changes; --- "Table 1 in the" hole with long hole conical shaft hole "modified to" have a hole of the cone-shaped shaft hole "; --- Table 3 in the shaft hole length 18,22 were changed to 16,20, an increase of 900,1000 two lengths; --- The length L1 of Table 4 is divided into "long series" and "short series"; --- Table 4 in the diameter dz limit deviation H10 to H8, and the corresponding deviation of the value of the corresponding adjustments; In Table 4, the diameter 6,7 increases the L1 value "18" and the d1 value "16", the diameter 8, 9 increases the L1 value "22" and the d1 value "24" Diameter 10,11 increases the L1 value "25" and the d1 value "28"; --- Change the limit of the "hole dz" in Table 6 to "axis, hole with code" and change all values to H8/k8 code; --- rectangular spline shaft hole and involute spline shaft hole coupling mark unified with Figure 2 said; --- the contents of the standard editorial changes, some of the contents of the value of the amendment. This standard is proposed and assigned by the National Committee on Standardization of Machine Shaft and Accessories (SAC/TC109). This standard drafting unit. in the machine productivity promotion center, Taiyuan Heavy Industry Co., Ltd., Yueqing City coupling plant, Zhejiang Huatai coupling Limited company.
