Rotary actuators can be adapted to form the joints of a robot, providing high levels of mechanical stiffness and torque. They have compact yet heavy-duty designs. These kinds of actuators can be implemented to yield a torque-to-weight ratio about 10 times higher than a standard motor and Harmonic Drive configuration. One of the advantages of rotary actuators is that they can be added to a system easily, with a simple insertion between two links. Their precision makes them ideal not only for robots, but for other industrial applications and for testing. Position sensor options of varying accuracy 12, 17, 19 bit can give you greater control of the servo valve, to provide the precision and special capacity needed for certain purposes. Actuators of the same size can also be designed as single-vane or double-vane types, the single-vane allowing for better range of movement and the double-vane providing more torque.

Welcome to Thomasnet. In this guide, we will provide detailed explanations of the various types of actuators, their applications and uses throughout industry, considerations when selecting them, and the top suppliers, manufacturers, and distributors for sourcing the correct actuator for your project. Actuators are mechanical or electro-mechanical devices that provide controlled and sometimes limited movements or positioning which are operated electrically, manually, or by various fluids such as air, hydraulic, etc. Two basic motions are linear and rotary. Linear actuators convert energy into straight line motions, typically for positioning applications, and usually have a push and pull function. Some linear actuators are unpowered and manually operated by use of a rotating knob or handwheel.

A rotary actuator is an actuator that produces a rotary motion or torque. The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators are electrically powered; others may be powered pneumatically or hydraulically , or use energy stored in springs. The motion produced by an actuator may be either continuous rotation, as for an electric motor , or movement to a fixed angular position as for servomotors and stepper motors. A further form, the torque motor , does not necessarily produce any rotation but merely generates a precise torque which then either causes rotation or is balanced by some opposing torque. Stepper motors are a form of electric motor that has the ability to move in discrete steps of a fixed size. This can be used either to produce continuous rotation at a controlled speed or to move by a controlled angular amount.

A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers , and in many other places where linear motion is required. Hydraulic or pneumatic cylinders inherently produce linear motion. Many other mechanisms are used to generate linear motion from a rotating motor. Mechanical linear actuators typically operate by conversion of rotary motion into linear motion.

Thanks to technological advances and the onset of the automation era , human-powered devices increasingly became a thing of the past, giving way to their automation through the use of actuators. When speaking of mechanical actuators , we are referring to an inherently mechanical mechanism whose function is to provide a force to move another mechanical device. The force generated by an actuator comes from three possible sources : pneumatic pressure, hydraulic pressure or electric motive power.

The Eckart HSE4 rotary-linear-actuator is a combination of a rotary actuator and a dual-action linear cylinder. Consequently, with the HSE4, a rotary movement and and a linear movement can be executed in an extremely small space. Since the rotary actuator and the linear cylinder are hydraulically driven separately, any movement sequences can be selected, such as rotaring to the left and right, linearly extending and retracting, etc. If both components are driven evenly, then both types of movement will be executed synchronously.

ГЛАВА 34 Сьюзан сидела одна в помещении Третьего узла, ожидая возвращения Следопыта. Хейл решил выйти подышать воздухом, за что она была ему безмерно благодарна. Однако одиночество не принесло ей успокоения. В голове у Сьюзан беспрестанно крутилась мысль о контактах Танкадо с Хейлом. Кто будет охранять охранников. - подумала. Quis custodiet ipsos custodes.

Начала просматривать длинные строки символов на экране, пытаясь найти то, что вызвало задержку. Хейл посматривал на нее с самодовольным видом. - Слушай, я хотел спросить, - заговорил.  - Что ты думаешь об этом не поддающемся взлому алгоритме, который, по словам Танкадо, он хотел создать. У Сьюзан свело желудок.

 Спасибо, - сказал Беккер.  - Я сегодня улетаю. Офицер был шокирован. - Вы же только что прибыли. - Да, но человек, оплативший авиабилет, ждет.

 Лжец! - выкрикнула Сьюзан.  - Я видела твою электронную почту. Хейл замер, потом повернул Сьюзан лицом к. - Ты вскрыла мою электронную почту. - А ты отключил моего Следопыта. Хейл почувствовал, как кровь ударила ему в голову.

Хейл пожал плечами: - Зато он не имеет ничего против твоего присутствия. Тебе он всегда рад. Сьюзан заставила себя промолчать. Хейл хмыкнул себе под нос и убрал упаковку тофу. Затем взял бутылку оливкового масла и прямо из горлышка отпил несколько глотков.

Она снова почувствовала себя школьницей. Это чувство было очень приятно, ничто не должно было его омрачить. И его ничто не омрачало.

С самого начала его преследовала мысль, что звонки Северной Дакоты - это западня, попытка японских конкурентов выставить его дураком.
