Introduction

Pneumatic devices are used as drives of clamping and transporting mechanisms, for remote control and regulation, in instrumentation, in automation of machines and devices operating in aggressive environments, in conditions of fire and explosion; radiation, at high temperatures, high vibration.

Advantages of pneumatic systems: reliability of operation, simplicity of structures, comparative ease of their operation and maintenance, relative cheapness, environmental safety.

Disadvantages of pneumatic systems: low response speed, inevitable air leaks from the system significantly reduce the efficiency of pneumatic devices.

The most widespread in robotic systems were two-way pneumatic drives.

When designing pneumatic actuators, it is necessary not only to correctly select their structural diagrams, including control diagrams, but also to determine the dimensions of actuators, air sprayers and other elements, as well as flow sections and maximum permissible lengths of connecting pipelines. The weight, cost, reliability and speed of the system depend on the correct size selection. The choice of parameters, despite the simplicity of the device design, is a rather difficult problem. Practice shows that errors in assessing the capabilities of the pneumatic drive and determining its parameters are very common.

Conclusion

The absence of simple and reliable methods for calculating the pneumatic drive affects the selection of dimensions of the actuator, control equipment and pipelines. Since the diameter of the cylinder or the flow sections of the line elements increases the danger that the required speed of the drive cannot be realized, it is necessary to select the dimensions of pneumatic devices with a large margin. Piston diameter and rod diameter were selected taking into account calculations, required requirements for long-stroke pneumatic cylinders () and conditions of permissible deflection.

Thus, based on the specified conditions and calculations, a two-way pneumatic drive with a double-sided rod was designed. Field of application - transporting devices.

Cylinder diameter.

Rod diameter.

Based on the selected parameters, a drawing of a pneumatic motor with a specification, a working drawing of the front cover, a pneumatic circuit was developed.
