Today's highly advanced and integrated designs of gear grinding machine allows the operator to enter the parameter such as helix angle, pressure angle, module etc.
The angle corresponding to in-cylinder peak temperature, to which it should correspond the maximum ion concentration, is expected between the TDC and the peak pressure angle; but the sensing dynamics, the local temperature measurement, and probably other aspects very complex to consider result experimentally in a "thermal" or "post-flame" ionization peak extremely close to the peak pressure angle.
Limited Tenders are invited for Procurement of high pressure angle pattern multistage drain
Now the pressure angle has increased, and there will be an outburst," said Grigoryan.
Traditional transmission pressure angle is usually used to assess the limb of a single loop and should not be utilized for the evaluation of spatial parallel mechanism.
The parameters of the mating gears are: normal module [m.sub.n], pinion and wheel number of teeth [z.sub.p] and [z.sub.w], normal pressure angle [[alpha].sub.n], pitch helical angle [[beta].sub.p], center distance d, pinion and wheel moments of inertia [I.sub.p] and [I.sub.w], pinion and wheel loads [M.sub.p] and [M.sub.w], teeth contact stiffness K and damping D.
The procedure aims to limit the maximum value of the pressure angle and obtain a cam dimension compatible with the locomotion unit size.

Detailed ocular examination of both eyes were performed including best corrected visual acuity, slitlamp biomicroscopic examination, intra ocular pressure Angle evaluation by gonioscopy using Zeiss goniolens was done.
where s is the tooth thickness along the pitch cylinder, [r.sub.1] is the pitch radius, [alpha] is the standard pressure angle, and [[alpha].sub.y1] is the pressure angle at radius [r.sub.y1].
On the eve of one of the most important matches of her life, Saina played down the pressure angle. "There's pressure, no doubt about that.
Saina played down the pressure angle defeating Chew 19-21, 23-21and 21-13 to win the 38th gold for the country.
