Stress Concentration factor Analysis of Helical Gear Drives with Asymmetric Teeth Profiles

Journal of Engineering, 2018
This study investigates the influence of asymmetric involute teeth profiles for helical gears on the bending stress. Theoretically, bending stress has been estimated in spur involute gears which have symmetric teeth profile by based on the Lewis, 1892 ...

Development of a free-form tooth flank optimization method to improve pitting resistance of spur gears [PDF]

MATEC Web of Conferences, 2022
Although steel involute gears are the standard solution for gear transmissions, they tend to suffer from poor pitting resistance. Pitting typically occurs when the gear tooth flanks have high equivalent curvature at the contact point and/or when the ...

Tooth contact analysis of spur gears. Part 1-SAM analysis of standard gears

MATEC Web of Conferences, 2017
The involute gears are sensitive to the misalignment of their axes which determines transmission errors and perturbations of pressures distributions along the tooth flank. The concentrated contacts in gears are no longer as Hertz type.

A differential evolution algorithm for tooth profile optimization with respect to balancing specific sliding coefficients of involute cylindrical spur and helical gears

Advances in Mechanical Engineering, 2015
Profile shift has an immense effect on the sliding, load capacity, and stability of involute cylindrical gears. Available standards such as ISO/DIS 6336 and BS 436 DIN/3990 currently give the recommendation for the selection of profile shift coefficients.

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Interference in Internal Involute Spur Gears

Transactions of the Japan Society of Mechanical Engineers, 1955
This paper deals with the interference in internal involute spur gears and shows, giving the pressure angle α and the addendum (for module) ρ1, ρ2, that the minimum tooth difference to avoid the trochoidal interference is nearly equal to (ρ1+ρ2)cosec2δ and that of avoiding the trimming is nearly equal to 2 (ρ1+ρ2)cosec2δ where (2δ-sin 2δ)/2sin2δ=tanα ...

Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse

Advanced Science, EarlyView.
An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...

TEHL Analysis of Rough Surface Spur Gears with Non-Newtonian Lubricants under Sudden Overloads

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
The time-dependent modified Reynolds equation, elasticity equation, and energy equation with initial conditions were formulated and solved numerically using a multi-grid multilevel with full approximation technique for an involute spur gear.

Study of the tooth contact for high contact ratio spur gears with long tip relief [PDF]

MATEC Web of Conferences, 2019
Profile modifications are commonly used to avoid shocks between meshing gear teeth produced by the delay of the driven gear, and the subsequent sooner start of contact, due to the teeth deflections.
