What is the rod?

The main rod is part of any driver that physically transmits the mechanical output of the driver to the device designed to control. In most cases, this part is slightly more than a simple, straight metal rod or rod. However, some control systems have relatively complex rod assemblies consisting of several links. The design of the rod is largely dictated by the type of driver, connected with the output torque and control of the device type. Most medium to cumbersome rods are made of metal, with lighter aluminum examples or different plastic stages. They are driven devices that can use electric motors, electromagnetic coils and compressed gas or oil as energy sources. As diverse as they can be in design and function, most of these devices transmit work movement to their activated device using drive. This part of the controller consists of a physical connection between the output mechanism of the drive and the activated device.

These parts are in most cases relatively simple direct components made of round or profiled stocks. A large ram on a hydraulic cylinder used to tilt a bucket on a machine moving on Earth is a good example of a simple driver rod. On the other hand, small boards that move head readers on the computer's hard disk are also rod drivers. Direct rods of the driver usually occur on performance that produces linear or line. In many cases, these rods are simply an extension of the internal mechanism of generating a power supply equipped with a caliper or a locking hole at their ends for connecting to the activated device.

rotary drivers often have oval or half-round cams that transmit their work movement, some of which are modular design, consisting of two or more separate pieces. In the types of rotary and linear output types, the drive rod is most commonly designedfor steel or finer alloys such as brass or aluminum. Heavy drives that produce a large amount of torque will usually have heavy hard steel rods capable of dealing with extreme loads. Light controls can have rods made of composites or reinforced plastic. Many of them are hollow in the cross -section to save weight and at the same time benefit from the own force of cylindrical structures.
