Linear drive (double acting)

Former Member

Hello,

I am trying to replace a double acting pneumatic cylinder by an electric driven linear drive.

 

A two segment funnel is opening by the cylinder. The product in the funnel(0.2-2Kg) helps to open. To stop the funnel from opening a force of 70 Newton is needed. This pull-force is needed for 3 second out of the 4.

 

The specs i need are the following:
Stroke: 25mm
Pull Force: 70 Newton (only when stroke = 0)
Push force: 5 newton(when stroke is +20mm)
Duty cycle: 80%

 

 

 

I hope this is all the information needed, if not, i'd like to hear.

 

Kind regards,
Stef

  • How fast does it need to move?

    There are lots of (expensive) sealed electric actuators and jactuators on the market, but usually they move quite slowly.

    It might be less costly to use a high ratio gearmotor with a connecting rod to convert angular motion to linear.

    If you use a worm gearbox, it will not move when power is not present.
