DESIGN AND ANALYSIS OF UNIVERSAL COUPLING IN POWER TRANSMISSION

The Cardan joint suffers from one major problem: even when the input drive shaft rotates at a constant speed, the output drive shaft rotates at a variable speed, thus causing vibration and wear. The variation in the speed of the driven shaft depends on the configuration of the joint. Such configuration can be specified by three variables. The universal Cardan joints are associated with power transmission systems.

They are commonly used when there needs to be angular deviations in the rotating shafts. It is the purpose of this research to study the dynamics of the universal joints and to propose some practical methods for improving their performance. The task is performed by initially deriving the motion equations associated to the universal joints.

That is followed by elaborating on the oscillatory behavior in the rotational speed and the torque that transmits through the intermediary shaft. The forces in the joint bearings are calculated by using an analytical method that is also supported by the numerical modeling. Such models are also used in order to calculate the rhythm and the amount of the excess loads on the joint. This is suggested as a systematic procedure in the search for the causes of the failures in these popular bearings.

With the same purpose in mind some defected bearings with deformed sections were selected for the laboratory examinations.

By analyzing the loading behavior and the surface conditions of the defected bearings and by comparison with the known fatigue theories attempts are made in order to dig into the causes for the failures in these joints and their bearing surfaces. With the aim of improving the performance and the life expectancy of these popular elements of the machineries, some practical recommendations are also suggested.

DESIGN AND ANALYSIS OF UNIVERSAL COUPLING IN POWER TRANSMISSION

Vibration is a torsional vibration essentially, which will produce additional stresses in the shaft, and when the stress exceeds the allowable limit total the shaft parts will produce fatigue damage. The vibration analysis on the tripod sliding universal joint of ships is analyzed including modal analysis and response spectrum analysis. The analysis result shows that it need to increase the strength of the shell and the tripod in the future design to enhance the reliability, safety and work life of the tripod sliding universal joint.

Design recommendations are provided for both allowable stress design and load factor design. Types Normal universal joints Double universal joints 5. In other words, rotation of the two bodies about the direction perpendicular to the two axes will be equal. Comprehensive source of information on bolted and riveted structural joints as well as an explanation of their behavior under various load conditions. As a class project, I have analyzed an Universal Joint. The analysis revealed that the maximum stress was occurring at both the yokes of universal joint at the middle span. Graph is a comparison between input and output shaft angular velocity which changes according to the angle between the universal joint.

Show all documents This speed fluctuation will increase with the angular distinction between the shafts. Another, additional common, name for a Cardan joint. Conceptual Design and Preliminarily Structural Analysis of Inflatable Basket for an Asteroid Capturing Satellite design , FEM analysis and testing of an inflatable space structure is presented in [11], in which the development of an inflatable re-entry vehicle based on a cone-shaped configuration made by a series of inflated rings is described in theoretical, numerical and experimental aspects. The paper [12] shows a good agreement between simulation results obtained with the LS-DYNA code and the experimental tests on the airbag structure of the Orion crew module; the work by [13] also describes a review of the methods for the structural analysis of airbags, focusing the attention on the problem of reducing the effects of the landing on the Mars surface, topic faced by [14] as well. The use of inflatable structures and methods for its structural analysis are also described with reference to expandable lunar habitats [15], and to antennas for small Cubesat satellites [16].

Volume 7 Issue 4 Failing to design the joint without considering these factors may lead to premature fatigue fracture and ultimately fail the entire joint assembly. This work can be used as a textbook as well as a reference for practitioners, scientists, and students dealing with drive technology. Universal joint in a rigid rod that allows the rod to bend in any direction, and is commonly used in shafts that transmit rotary motion.

Простое число. Джабба посмотрел на таблицу, что стояла на мониторе, и всплеснул руками. - Здесь около сотни пунктов.

Она в конце концов перестала протестовать, но это продолжало ее беспокоить. Я зарабатываю гораздо больше, чем в состоянии потратить, - думала она, - поэтому будет вполне естественным, если я буду платить. Но если не считать его изрядно устаревших представлений о рыцарстве, Дэвид, по мнению Сьюзан, вполне соответствовал образцу идеального мужчины. Внимательный и заботливый, умный, с прекрасным чувством юмора и, самое главное, искренне интересующийся тем, что она делает.

Но было что-то. Сьюзан на мгновение заколебалась и оглянулась на заблокированную дверь. Всего двадцать минут, подумала. Повернувшись к терминалу Хейла, Сьюзан вдруг уловила странный мускусный запах - очень необычный для Третьего узла.

Однако одиночество не принесло ей успокоения. В голове у Сьюзан беспрестанно крутилась мысль о контактах Танкадо с Хейлом. Кто будет охранять охранников.

 Провайдер находится в районе территориального кода двести два. Однако номер пока не удалось узнать. - Двести два.
