節圓直徑 的英文怎麼說
中文拼音 [jiéyuánzhíjìng]
節圓直徑
英文
diameter pitch-
The relation of radius of curvature and error as well as formulas of increasing parameters on condition of constant error are diverted. the equation of the line on the center of approximate circular arc is obtained ， and it can avoids the trouble that numerical solution owns possibility of no convergence and simplifies node calculation of non - circular curve
導出了曲率半徑與逼近誤差之間的關系和等誤差條件下的參數遞推公式，建立了通過逼近圓弧圓心的直線方程和圓心坐標計算公式.按這種方法用圓弧逼近平面參數曲線，不需要求解非線性方程組，避免了計算可能不收斂的麻煩，簡化了非圓曲線的節點計算過程Pbd pitch circle diameter
節圓直徑Pitch diameter, d
節圓直徑， dP. d. pitch diameter
節圓直徑Changing the diameters and fixing angles of milling cutter can meet the machining requirements of helical surface. this method has been applied in the process of manufacturing twin - screw in rubber and plastic mechanics, which simplifies the process route and shortens the prepare time in production and at the same time saves the cost and improves technical and economic benefits
通過改變圓柱立銑刀的直徑和加工安裝角度來滿足螺旋面的加工要求，該方法已在橡塑機械用同向雙螺桿的加工中得到應用，縮短了加工工藝路線，減少了生產準備時間，節約了加工成本，取得了良好的技術經濟效益。Based on ansys, this paper studies stress concentration on single notch of eight kinds of high strength bolts used in grid structure, obtaining their stress concentration coefficients, discussing the effect of ascending angle, bottom radius of screw thread and bolt - ball on stress concentration, introducing their effect coefficients of a1, a2, a3, putting forward the formulae of stress concentration coefficient
本文以ansys有限元軟體為研究手段，針對網架螺栓球節點的8種螺栓規格進行單缺口應力集中分析，定量求得相應的應力集中系數k _ t ；論述了螺紋升角、螺紋牙根圓角半徑r及球栓直徑比d / d對k _ t的影響，並引入相應的影響系數_ 1 、 _ 2及_ 3 ，最終提出了應力集中系數k的計算公式。The optimization selection and comparison have been conducted on the ratios of major structural dimensions of ball cage patterned constant speed universal joint namely the ratio between central circle diameter of steel ball and ball diameter, the ratio between outer diameter of universal joint and diameter of graduation circle of inner sleeve spline and the ratio between eccentricity of ball cage patterned constant speed universal joint and central circle radius of ball
對球籠式等速萬向節的主要結構尺寸即鋼球中心圓直徑與鋼球直徑之比、萬向節外徑與內套花鍵分度圓直徑之比，以及球籠式等速萬向節的偏心距與鋼球中心圓半徑之比進行了優化選擇和比較。分享友人
