Pratical power transfer: Linear actuator-driven pneumatics

Here is one solution I came up with while looking for a practical way to transfer significant forces over large distances or into moving components, without the headaches related to gearing mechanisms, axle extenders, etc. It is a linear actuator that drives the piston of a standard pneumatic cylinder directly, and the piston is cross-connected to another one, which reflects its motion and does the required job. (It can also inverse the motion by connecting them directly, rather than "crosswise".)



Of course, this is just a concept and design could be vastly improved on, especially regarding reinforcements that may be needed when the forces become really large. Theoretically, it could work with only one of these two hoses as well if the power is needed only in one direction, but is much more reliable and easier to control when their both ports are in use.


Unfortunately, due to the friction within the cylinders, the target piston is not nearly as precise as the input set by the linear actuator. However, its primary task is to transfer serious force, rather than do it extremely precisely. Due to an enormous gearing ratio of the linear actuator, its input torque is easily handled by almost any Lego motor. Just keep in mind that the total stroke length of the linear actuator exceeds that of a pneumatic cylinder, therefore (at least in this configuration) it can't be retracted completely.

Of course, the concept of cross-connected pneumatic cylinders that follow each other's motion can be practically applied in various other ways, however they must be driven "externally" ― that is, introducing a pump with a T-connector would not work as there is no output for the compressed air to escape from the system!

  20. gigs promote SEO - Search Engine Optimisation, is an extremely valuable skill. The job websites - at a time of increasing unemployment - seem to be full of very well paid positions for SEO executives. The reason for this is that actually, there are very few people in the UK who are truly skilled in SEO - and for that reason, those that are tend to choose to work for themselves regardless of the large amount of money they could earn working for an SEO firm.
