These directions replace the previous design directions of the same number, without amendment. The values presented there were revised for this edition and a chapter was added for shaft shiftings.
这些说明取代了之前相同编号的设计说明，未作任何修改。本版对其中的数值进行了修订，并增加了关于轴移位的章节。
These directions comprise half-speed ( 1500 min − 1 1500 min − 1 1500min^(-1)1500 \mathrm{~min}^{-1} and 1800 min − 1 1800 min − 1 1800min^(-1)1800 \mathrm{~min}^{-1} ), and full-speed ( 3000 min − 1 3000 min − 1 3000min^(-1)3000 \mathrm{~min}^{-1} and 3600 min − 1 3600 min − 1 3600min^(-1)3600 \mathrm{~min}^{-1} ) bearings of 280 ÷ 900 mm 280 ÷ 900 mm 280-:900mm280 \div 900 \mathrm{~mm} diameters. The data required for the layout of the 3 -segment standard journal bearings have been established. Energy losses, oil needs, oil-heating, and admissible maximal bearing loads are presented as a function of the diameter for the entire diameter range. The shaft shiftings can be determined for the entire diameter and rotational speed ranges.
这些方向包括直径为 280 ÷ 900 mm 280 ÷ 900 mm 280-:900mm280 \div 900 \mathrm{~mm} 的半速（ 1500 min − 1 1500 min − 1 1500min^(-1)1500 \mathrm{~min}^{-1} 和 1800 min − 1 1800 min − 1 1800min^(-1)1800 \mathrm{~min}^{-1} ）和全速（ 3000 min − 1 3000 min − 1 3000min^(-1)3000 \mathrm{~min}^{-1} 和 3600 min − 1 3600 min − 1 3600min^(-1)3600 \mathrm{~min}^{-1} ）轴承。3 段标准轴颈轴承布局所需的数据已经确定。在整个直径范围内，能量损失、机油需求、机油加热和允许的最大轴承载荷与直径相关。可以确定整个直径和转速范围内的轴偏移。

Fully enclosed journal bearings with a diameter of d ≥ 400 mm d ≥ 400 mm d >= 400mmd \geq 400 \mathrm{~mm} enter the area of turbulent bearing friction at or above 3000 min − 1 3000 min − 1 3000min^(-1)3000 \mathrm{~min}^{-1} under the usual BBC operating conditions. The resulting heavy increase in bearing losses can be controlled by the use of segment bearings. In addition, segment bearings show excellent stabilizing properties. The use of segment journal bearings is treated in HTGD 662014.
直径为 d ≥ 400 mm d ≥ 400 mm d >= 400mmd \geq 400 \mathrm{~mm} 的全封闭轴颈轴承在通常的BBC工作条件下，当直径达到或超过 3000 min − 1 3000 min − 1 3000min^(-1)3000 \mathrm{~min}^{-1} 时，就会进入轴承摩擦湍流区。由此造成的轴承损耗的严重增加可以通过使用分段轴承来控制。此外，分段轴承还具有优异的稳定特性。HTGD 662014对分段轴颈轴承的使用进行了研究。
