Coupling | Types, Advantages, Disadvantages, Applications

It can be very difficult to fully center two shafts when connecting them together. Shaft deflection caused in operation of the machinery, thermal expansion of the shafts, warping of support plates over long periods of use, and wear of shaft bearings can also make it difficult to keep the shafts centered. The role of the coupling is to resolve these types of problems through the selection of the right coupling for the job. Miki Pulley provides a wide range of coupling products not just for general purpose motors, but for everything from servo motors, which demand ultra-precise control, to engines, which generate high vibration and large shocks. These metal disc-spring couplings with ultra-high torsional stiffness were developed for servo motor applications. The disc-spring method provides excellent properties: firmness in the torsional direction but flexibility in the bending, step-difference, and axial directions.

Study on Rigid-Flexible Coupling Effects of Floating Offshore Wind Turbines

What is the difference between rigid and elastic coupling in master-slave architecture and why direct speed control available only in elastic coupling? Published date: 23 May Rigid and elastic are 2 often used types of mechanical connection between 2 motors. As their name say, the rigid connection is the type of connection where motor shafts are firmly connected together or connected via gearbox e. In other word saying, in rigid connection the motors have to have the same speed. It is not possible at any time that one motor rotates faster than the other.

A coupling is a mechanical device which is used to hold two rotating shafts together. It is a permanent joint, unlike clutch which can be disengaged on the will of operator. With the help of couplings, we can join two shafts which are intersecting, colinear or parallel with a small distance. Oldham coupling is used to connect two parallel shafts which are a small distance apart. We all know that a clutch which is generally used in automobiles is also used for connecting two rotating shafts but there is a basic difference between a clutch and coupling. In clutch we can disengage the rotating shaft at our will whenever we want but in coupling it is not possible. In our domestic electricity generator, we see that a shaft is rotated by an engine by converting chemical energy of fuel into mechanical energy.

In order to account for rigid-flexible coupling effects of floating offshore wind turbines, a nonlinear rigid-flexible coupled dynamic model is proposed in this paper. The proposed nonlinear coupled model takes the higher-order axial displacements into account, which are usually neglected in the conventional linear dynamic model. Subsequently, investigations on the dynamic differences between the proposed nonlinear dynamic model and the linear one are conducted. The results demonstrate that the stiffness of the turbine blades in the proposed nonlinear dynamic model increases with larger overall motions but that in the linear dynamic model declines with larger overall motions. Deformation of the blades in the nonlinear dynamic model is more reasonable than that in the linear model as well. Additionally, more distinct coupling effects are observed in the proposed nonlinear model than those in the linear model.

1.0 Introduction

Забудьте о ней! - Он отключил телефон и запихнул за ремень. Больше ему никто не помешает. В двенадцати тысячах миль от этого места Токуген Нуматака в полной растерянности застыл у окна своего кабинета. Сигара умами безжизненно свисала изо рта. Сделка всей его жизни только что распалась - за каких-то несколько минут.

 - Я должен найти его партнера, прежде чем он узнает о смерти Танкадо. Вот почему я тебя вызвал. Мне нужна твоя помощь.

Нуматака затянулся сигарой умами и, выпустив струю дыма, решил подыграть этому любителю шарад. - Итак, вы хотите продать ключ, имеющийся в вашем распоряжении. Интересно. А что по этому поводу думает Энсей Танкадо.

Сьюзан стукнула кулаком по столу: - Нам необходимо это кольцо. Ведь на нем - единственный экземпляр ключа! - Теперь она понимала, что нет никакой Северной Дакоты, как нет и копии ключа. Даже если АНБ расскажет о ТРАНСТЕКСТЕ, Танкадо им уже ничем не поможет. Стратмор молчал. Положение оказалось куда серьезнее, чем предполагала Сьюзан.

В одно мгновение Сьюзан все стало ясно. Когда Стратмор загрузил взятый из Интернета алгоритм закодированной Цифровой крепости и попытался прогнать его через ТРАНСТЕКСТ, цепная мутация наткнулась на фильтры системы Сквозь строй. Горя желанием выяснить, поддается ли Цифровая крепость взлому, Стратмор принял решения обойти фильтры.
