Повний текст джерелаRadius hardening on journals of forged steel Diesel engine crankshafts is performed in order to increase fatigue life characteristics. This requirement may be necessary if the demands for engine power are to be increased, but where the existing crankshaft design is close to its fatigue limit, such that an increase in loading will cause it to'fail. Induction hardening of journal radii changes the make-up of the material from a coarse to a fine crystalline structure which alters the features of crack propagation. As a consequence of this higher loads can be applied onto the crankshaft without ultimately resulting in catastrophic material failure. Extending the induction hardened zone from the bearing surfaces into the radii of journals, culminates in process difficulties which are not experienced in non-radius hardened Hardening of journal radii induces crankshafts. as well as releases stresses in the crankshaft webs. This results in a deformation of the crankshaft which can be measured in the form of journal runout. Such a problem cannot be overcome by straightening the crankshafts in order to reduce runout, since this will cause Straightening hand induces the radii to crack once hardened. in the unhardened state on the other stresses which will be released again after hardening. This results in an increase in runout. High runout indicates that stresses have been induced into the crankshaft material. This is undesirable since this will make critical manufacturing processes such as grinding, governing of journal lengths, uncontrollable. It can furthermore result in creep of the crankshaft long after the manufacturing date. This results in crankshaft deformation, noticeable through an increase in runout. Since the crankshaft cannot be straightened after hardening, the consequence is that it will be unusable. The process must therefore be developed in such a manner, that all variables which can contribute towards stress induction resulting in journal 'runout, must be investigated and resolved.

Повний текст джерелаThe active magnetic bearing (AMB) is a relatively new technology which has
many advantages compared with conventional bearing design. In an AMB system,
the rolling-element back-up bearings are indispensable to protect the magnetic
bearing rotor and stator, and other stationary seals along the rotor shaft. In this
paper, a theoretical formulation is proposed and solved numerically to examine the
transient response of the flexible rotor, from the time just previous to the AMB
shuts down and including the rotor drop onto the back-up bearing. The backward
whirl of the rotor, which may lead to the destructive damage of the machinery, has
been analytically predicted at very light support damping and very high support
damping. Also, the vibration due to the non-linearity of the contact point geometry
has been included in the analysis. The influence of the support damping on the
displacement of the disk and also the contact force between the journal and the
inner-race of the back-up bearing have been computed for various rotor system
parameters. By comparing these results with the optimum support damping for
the simple flexible rotor model, it is shown that this support damping optimization
can be applicable for specifying the required optimum range of support damping
for the back-up bearings of AMB systems.

Resumo: Este trabalho tem como objetivo propor um modelo de dinâmica flexível dos componentes de um compressor alternativo monocilíndrico de refrigeração. Tal modelo representa um aperfeiçoamento da modelagem dinâmica utilizada, que supõe mancais rotativos fixos ou pinados. A modelagem dinâmica flexível do compressor é útil na analise dos esforços de natureza elástica e dissipativa que ocorrem nos mancais de sustentação do conjunto. Esses resultados podem também ser utilizados numa correta medição da energia dissipada pelos mancais. O modelo dinâmico utiliza um mecanismo biela-manivela, pistão e eixo, sujeitos ao carregamento da pressão que o fluido refrigerante exerce sobre o pistão no interior do cilindro. A modelagem incorpora efeitos giroscópicos e utiliza mancais flexíveis nos acoplamentos dos componentes, o que proporciona maior mobilidade ao modelo. O Método de Newton Euler é utilizado na analise das forças e momentos atuantes no sistema para a obtenção das equações diferenciais que representam o seu movimento. As equações dinâmicas, por sua vez, são resolvidas numericamente através do método de Runge-Kutta. Observou-se que a modelagem da oscilaãoo dos componentes rotativos no conjunto eixo-biela-manivela é capaz de produzir esforços diferenciados nos mancais do compressor quando comparado aos esforços de mancal presentes num modelo pinado
Abstract: The work consists in fiding a flexible dynamics model of a single cylinder, reciprocating refrigeration gas compressor. The model represents an improval to the current dynamic model of compressors, that use fixed or pinned rotation journal bearings. An efficient dynamic model of the compressor is useful in the analysis of elastic and dissipative loads that occur in the system¿s internal bearings. The results produced by the model can also be employed in the correct measurement of the energy dissipated at the bearings. The dynamic model consists of a rotor, cranckshaft, connecting rod and piston, all subject to the load from compression of the refrigerant fluid. The model incorporates gyroscopic effects and utilizes flexible bearing couplings, which yield greater mobilty to the moving mechanisms. The Newton-Euler method is used in the analysis of acting forces and torques, establishing the necessary differential equations that describe the movement of the system. A numerical solution of the dynamic equations is obtained through use of the Runge-Kutta method. Application of the model shows that oscillations of the rotating internal components of the compressor yield increased loads to the bearings, as compared to a pinned rotation model
