Tension, springs, force, gears 3

[confused290181]

Hi Guys,

My company use an arrangement where two probe parallel arms are connected with two tension springs with a measured force at measure head set to 4.5Kg. Spring/probes are open and closed by a smc cylinder driving a cam between the probe arms.

The new design removed the cam now the cylinder drives one probe away from the other and the probes are geared together so they move apart.

However this gearing is causing the force required to get 4.5 kg at the head to be increased ie using a scale weight on one arm force is set to 10Kg but on a load-cell at the measure head only shows 4.5kg

I know this is a little sketchy im happy to answer any questions you guys have for a new guy

Cheers

Instead of all the gearing and external springs you might want to take a look at the C-flex Bearing. to equalize and control your motion.
