Work of the planetary gear trains as differentials and their capabilities [PDF]

open access: yesMATEC Web of Conferences, 2019
Planetary gear trains can work differently, namely, with F=1 degree of freedom, i.e. as reducers or multipliers, and also with F=2 degrees of freedom, i.e. as differentials.

Kinematic Precision of Gear Trains [PDF]

open access: yesJournal of Mechanisms, Transmissions, and Automation in Design, 1983
Kinematic precision is affected by errors which are the result of either intentional adjustments or accidental defects in manufacturing and assembly of gear trains. This paper explains a general method for the determination of kinematic precision of gear trains.

Dynamics of early planetary gear trains [PDF]

open access: yes
A method to analyze the static and dynamic loads in a planetary gear train was developed. A variable-variable mesh stiffness (VVMS) model was used to simulate the external and internal spur gear mesh behavior, and an equivalent conventional gear train ...

Normalised Root Mean Square and Amplitude of Sidebands of Vibration Response as Tools for Gearbox Diagnosis [PDF]

open access: yes, 2012
Quick assessment of the condition of gearboxes used in helicopters is a safety requirement. One of the most widely used helicopter on-board-mounted condition monitoring system these days is the Health and Usage Monitoring System. It has been specifically

Hydraulic drive system prevents backlash [PDF]

open access: yes, 1965
Hydraulic drive system uses a second drive motor operating at reduced torque. This exerts a relative braking action which eliminates the normal gear train backlash that is intolerable when driving certain heavy ...

Dynamic Capacity and Surface Fatigue Life for Spur and Helical Gears [PDF]

open access: yes
A mathematical model for surface fatigue life of gear, pinion, or entire meshing gear train is given. The theory is based on a previous statistical approach for rolling-element bearings. Equations are presented which give the dynamic capacity of the gear
