Effects of linear and angular misalignment on a spur gear pair

Insight - Non-Destructive Testing and Condition Monitoring, 2011
This paper investigates the effects of linear and angular misalignments on static contact parameters in a gear pair, taken at various points during the gear meshing cycle. The parameters of interest include the degree to which the load is shared among the teeth in contact (load sharing ratio (LSR)), the reaction forces at the gear centres and the ...

Fatigue Life Analysis for Angular Contact Ball Bearing with Angular Misalignment

Journal of the Korean Society for Precision Engineering, 2016
Angular misalignment has a significant effect on the characteristics of angular contact ball bearings (ACBBs). This paper presents an analysis of fatigue life for ACBBs subjected to angular misalignment. A simulation model is developed with de Mul’s bearing model and the ISO basic reference rating life model.

Angular misalignment in induction motors with flexible coupling

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
The problem of angular shaft misalignment in motors — load systems coupled through flexible couplings is analyzed in this work. A model for the analysis and diagnosis of angular misalignment in induction motors is presented. It allows studying the angular shaft misalignment effects over the motor torque, instantaneous power and currents through dynamic

Angular Misalignment Effect on the Dynamic Behavior of Bearings

International Journal of Mechanical Engineering Education, 2006
Dysfunction of rotating machines is often caused by shaft misalignment. This defect generates some important loads and vibrations, and can lead to a premature failure of a bearing, shaft or coupling. The objective of this study is to survey angular misalignment. The first part deals with the development of a theoretical model describing the phenomenon.

Angular tilt misalignment loss at a GRIN rod lens coupler

Applied Optics, 1986
A geometric optics model for evaluating end separation and transverse offset losses at a graded-index (GRIN) rod lens to lens coupler is extended to the case of angular tilt misalignment loss. Two different fiber–lens combinations are examined, and the model is verified by comparison to experimental measurements, which show close agreement to the ...

A Low-Complexity Solution to Angular Misalignments in Molecular Index Modulation

2019 IEEE 30th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2019
Multiple-input multiple-output (MIMO) transmission approaches have been recently considered in the context of molecular communications due to desirable improvements they provide in terms of communication efficiency. Among these methods, molecular index modulation (molecular-IM) schemes yield a significant improvement in throughput and show promising ...

Both Tilt and Misalignment are Manifestations of Angular Induction

Perceptual and Motor Skills, 1993
With a Poggendorff configuration one sees two obliques as being misaligned, and with a Judd configuration one sees them as having different tilts, i.e., as being misoriented. It has been suggested that these are separate illusory effects. I submit, however, that one can see misorientation in the double Poggendorff and misalignment with a Judd-like ...

Shaft angular misalignment detection using acoustic emission

Applied Acoustics, 2014
Shaft angular misalignment (SAM) is a common and crucial problem in rotating machinery. Misalignment can produce several shortcomings such as premature bearing failure, increase in energy consumption, excessive seal lubricant leakage and coupling failure.

Effects of angular misalignments on fiber-optic alignment automation

Optics Communications, 2001
Automation of fiber-to-optic alignment is critical to the development of cost effective fiber-optic component manufacturing technologies. Key to the alignment automation is the angular alignment automation, which is now unavailable. But angular misalignments are unavoidable in practical fiber-optic aligning process.

Effects of angular misalignment on optical klystron undulator radiation

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2015
Abstract In this paper ,we analyze the important effects of optical klystron undulator radiation with an angular offset of the relativistic electron beam in the second undulator section. An anlytical expression for the undulator radiation is obtained through a transparent and simple procedure.It is shown that the effects of the angular offset is more
