Oscillating / Reciprocating Motion
Oscillating / Reciprocating Motion
(OP)
Good morning / evening ladies gentlemen.. And sleep deprived creatures..
I have an application that requires me to build a mechanism similar to a jigsaw, it has to have a fairly high RPM and around a 1.5 to 2 inch stroke.
Does anyone know of a linear actuator or off the shelf system that will provide me what I need?
It is going to be mounted onto an XY gantry, so ideally I would like to control the speed relative to the feed rate.
I throw the floor open to those brighter than myself (ie everyone)

Its my fault I should have mentioend I plan to run the mechanism nearly 8hrs a day
As far as a crank and piston.. I have that one up my sleeve as a last resort, the whole motor assembly will be rotating on a C Axis, the lighter and more balanced I can make the load... The better
Thanks a heap guys... Keep that grey matter simulated

If your rate of operation is not too high, you might be able to use an pneumatic actuator.

Try a search on "voice coil actuator".

Many applications I run into like this, the solution usually ends up being a cam follower (cause voice coils can't produce the force, and linear motors are too expensive).

The immediate benefit I see is the standard, easy to replace bearing with essentially zero free play.
