Nonlinear Dynamic Characteristics of Fixed‐Axis Gear Wear in Multistage Gear Transmission Systems
Shock and Vibration, Volume 2019, Issue 1, 2019., 2019 With the increasing service life of a gear transmission system, the gear teeth become constantly worn and the gear clearance increases. The increase in the clearance will produce a series of nonlinear changes that change the stability of the system and can even cause the loss of stability.

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018 High speed and heavy load put forward demanding requirements for the bending strength of spiral bevel gear. Shot peening, as a technological method, can greatly improve the bending strength of gear. During shot peening, a large number of subtle projectiles bombard the tooth surface of spiral bevel gear at an extremely high speed, which makes the latter

Vibratory Power Flow Analysis of a Gear‐Housing‐Foundation Coupled System
Shock and Vibration, Volume 2018, Issue 1, 2018., 2018 The marine gearbox is usually installed on a vibration isolation system in order to reduce oscillation transmitted to the ship foundation. However, researches on vibration transmission in the gear‐housing system and isolation system are currently independent.

On the dynamics of lubricated hypoid gears [PDF]
Mechanism and Machine Theory, 2012 The torsional dynamics of a vehicle differential hypoid gear pair is investigated. The model comprises applied torque, representing transmitted engine power, including engine order vibration. A number of gear teeth pairs transmit the applied torque through their lubricated conjunctions.
