pitch of helix的意思|示意

According to the new national gear standard, three deviation-measuring items must be included in the checkout of single gear: profile deviation, helix deviation and pitch deviation.

按照新的国家齿轮标准规定，对于单个齿轮必须检验三个偏差项目：齿廓偏差、螺旋线偏差和齿距偏差。

From the STMimages, we could see clearly the helix pitch and helix diameter of helix structure.

由STM图象中我们能清晰地观察到螺旋结构的螺距与螺径。

Because pitch deviation measuring technology is very mature, the main research objective of this thesis is laid on the checkout of profile deviation and helix deviation.

因齿距偏差测量技术已经很成熟，所以本论文的在位测量主要定位于检测齿廓偏差和螺旋线偏差。

A helix equation of time-varying pitch is established, revolving elliptic cylinder as equal angular velocity and rising as variable velocity at the same time.

建立了绕椭圆柱面以等角速度旋转，又以变速度上升的非定常螺距的螺旋线方程。

This paper presents a method for machining of taper cutting tools with equal helix Angle. The principle of the method is using taper helical curve with equal pitch to approach equal Angle one.

文章提出了一种在经济型数控机床上实现等螺旋角圆锥螺旋线的加工方法，其原理是用等导程螺旋线去逼近此种曲线。
