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 ...

Transmission errors in precision worm gear drives [PDF]
Transmission error is a measure of the positioning accuracy of a gear system. This has been widely documented in gearing for many years as the source of problems in noise and vibration.

Seeded fault detection on helical gears with acoustic emission [PDF]
, 2009 Acoustic emission (AE) is one of many technologies for health monitoring and diagnosis of rotating machines such as gearboxes. Although significant research has been undertaken in understanding the potential of AE in monitoring gearboxes this has been

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.

Measuring Geometrical Parameters of Involute Spur Gears to Sub-pixel Resolution [PDF]
Procedings of the British Machine Vision Conference 1992, 1992 The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel.

Theoretical and experimental working life comparison for a helical gear under linear pitting failure [PDF]
, 2007 For machine components like gears and bearings, working life calculation is one of the complex issues to deal with. This is because the mechanics of their operation is dependent on many parameters, like loading, friction and lubrication etc.

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.

Investigation of the involute spur gears with different pressure angles
Design of Machines and Structures, 2023 This article deals with an investigation of the choice of the profile shift coefficient for gears when the standard pressure angles of the gears are different. The basic idea for the study arose from a real-life problem where a gear in a piece of equipment needed to be re-placed.
