tooth profile measuring error

基本解釋

A double-disc mode instrument for measuring involute tooth profile is analyzed, which has some advantages, such as simple structure, no Abbe error caused by the stylus, etc.
分析了雙基圓盤式漸開線測(cè)量?jī)x的測(cè)量原理，其具有結(jié)構(gòu)簡(jiǎn)單、測(cè)量過程中無(wú)測(cè)頭位置引起的阿貝誤差等特點(diǎn)。
If the normal section in the center of the tooth line is taken as a tooth measuring and design section, when spline hob is designed in a plane meshing, the tooth profile error is minimum.
如果以齒紋中點(diǎn)法剖面作為齒形檢測(cè)和設(shè)計(jì)剖面，用平面嚙合法設(shè)計(jì)花鍵滾刀時(shí)，則齒形誤差最小。
Adopting the engaging process of the measuring rack- probe, the error of straight generatrix is measured, and by error analysis, the tooth profile error and tooth orientation error can be obtained.
采用刃邊齒條測(cè)頭，測(cè)量齒輪廓面的直母線偏差，通過誤差分析分離出齒廓總偏差和螺旋線總偏差。
