Study on the dynamic performance of tilt rotor supported .

Tilt rotor supported by rolling bearings is often used in mechanical equipment. In the past, researches on dynamic performance of bearing-rotor were mainly carried out for horizontal rotor, but there is insufficient reported research on the tilting rotors. In this paper, the dynamic performance of a tilt rotor supported by spherical roller bearings is studied.

Simple and Versatile Dynamic Model of Spherical Roller Beari

2. Dynamic Model of the Spherical Roller Bearing A spherical roller bearing consists of a number of parts, including a series of rollers, a cage, and the inner and outer raceways. Describing each component in detail can result in a simulation model with a large number of degrees-of-freedom. Additionally, as with all radial rolling bearings,

Spherical Roller Bearing Simulation Model with Localized .

Extensive research has been conducted to study the dynamics of ball bearings, while studies related to spherical roller bearings are short-shrifted. In this paper a three degree of freedom dynamic model of spherical roller bearing that takes into account the inner and outer race surface defects is introduced.

A Vibration Model of Ball Bearings with a Localized Defect .

Gomez et al. [15] presented a deep groove ball bearing model with localized defects to study the instantaneous angular speed variations of the balls. This model used a simple localized defect model with a rigidly defect depth, and the defect depth is also regarded as the variation of the contact deformation when the balls pass over the defect.
