Análisis del efecto del apriete y la rigidez de contacto en la precisión de un mecanismo de levas conjugadas
(2012)
Conference report
Restricted access - publisher's policyLos mecanismos de levas conjugadas requieren de un ajuste con apriete para compensar las tolerancias de fabricación y montaje y al mismo tiempo evitar la separación de las superficies de las levas y los ... -
Avoiding early failures in conjugate cam mechanism by means of different design strategies
(2016-01-01)
Article
Restricted access - publisher's policyTo solve the indetermination of forces existing in a form-closed cam mechanism formed by conjugate cams, where the contact between the cams and the follower rollers is constantly ensured by only the geometry of the elements, ... -

Conference report
Restricted access - publisher's policyEl monitoreo de las condiciones de vibración es comúnmente utilizado para incrementar la disponibilidad de las maquinas en general, reduciendo consecuentemente los daños o fallas en las mismas, incrementar su vida útil, ... -
Contact characterization between a cam and a crowned roller follower
(S. Ekinovic, S. Yalcin, J. Vivancos., 2014)
Conference lecture
Open AccessIn the higher pairs of a mechanism, like the one existing between a cam and roller follower, it is common to localize the maximum deformations, the maximum contact pressures and that appears the surface fatigue failure due ... -
