This standard is equivalent to ISO2727-1973 "Common Components for Modular Machine Tools-1 Scope
This standard specifies the relevant interchangeability dimensions of power boxes for modular machine tools. 2 Nominal dimensions and names
The nominal dimensions are specified in terms of the saddle width of the corresponding slide. The following nine nominal dimensions are used: 1
125, 160, 200, 250, 320, 400, 500, 630 and 800mm. The names are specified in terms of nominal dimensions.
3 Description
-Power box".
The dimensions of the power box with a nominal size of 125~250mm shall comply with the provisions of Figure 1 and Table 1. 8.1
The end face transmission key or shaft and flat key transmission can be adopted. 3.2 The dimensions of the power box with a nominal size of 320~800mm shall comply with the provisions of Figure 2 and Table 2. The transmission can be carried out by coupling or gear transmission, or other means. 4 Size

GB3668.5-83
This standard was proposed by the Ministry of Machinery Industry of the People's Republic of China. This standard was drafted and managed by the Dalian Modular Machine Tool Research Institute of the Ministry of Machinery Industry. The main drafters of this standard are Cao Weiqian and Li Fu: From the date of implementation of this standard, the former Ministry of Machinery Industry standards JB1522-75 "Nominal dimensions, parameters and interchangeable dimensions of power boxes with coupling transmission of common components of modular machine tools", IB-1523-75 "Nominal dimensions, parameters and interchangeable dimensions of power boxes with gear transmission of common components of modular machine tools" and JB2507-78 "Nominal dimensions, parameters and interchangeable dimensions of power boxes with end key transmission of common components of modular machine tools" will be invalid.
