Effect of Installation Errors of Helical Gear on Bearing Capacity [PDF]
, 2023 Broken tooth roots due to mounting errors in helical gears at high speeds and heavy loads are a common problem in steel mills. Based on the contact characteristics of helical gears, this paper uses the finite element method to simulate the bending stress at the root of the pinion gear and the contact stress at the tooth surface under two cases of ...

Influence of installation error on roundness error measurement [PDF]
IOP Conference Series: Materials Science and Engineering, 2019 Abstract The installation tilt causes the actual measured circular contour to be an elliptical contour [1], and the installation eccentricity causes the sampled points uneven [2], which can both affect the measurement accuracy of the roundness error [3, 4].
