Network standard hole size and tolerance related terms and definitions, symbols, codes according to the relevant provisions of GB15? and GB11334, the cone diameter tolerance, the basic back auxiliary diameter (chain large end diameter) is the basic size, The basic size and limit deviation values ​​are shown in Table 3.2. The round angle tolerance of the cone is shown in Figure 3.35, which is the same as the shape tolerance T. The cone diameter tolerance T is uniformly distributed in the cone diameter tolerance T, and the determined circle tolerance band is 3.35. The angle tolerance AT is expressed by the angle value, and the single and double minus limit difference is given. The basic single angle and over-limit deviation value of the chain angle are shown in Figure 1. The diameter of the cone is approved by the Ministry of Machinery Industry on April 11, 1906. +t, co

Inspection of 1124 round cans of strong tooth gear milling cutter (supplement)
When the large end diameter of the A1 face cone is inspected by a plug gauge, the diameter tolerance is converted into an end face comparison and inspected with a feeler gauge. The round angle error and shape error of the 42-meter round cone are inspected by color coating with a comprehensive rate gauge. The inspection method should comply with the relevant provisions of JB5563, and the contact rate should not be less than.
