We did run a compactor in the air suspended by just the backhoe. I recorded only a few data points, but it seems that the operating pressure is approximately 50% of what it was on firm ground. The compactor is suspended on four rubber mounts acting in sheer which do get hot. There is another...
We actually do have decent 65mm (mean dia) spherical roller bearings. A calculator on SKF's website estimated a frictional loss of ~171W (.23hp) for both bearings. In testing of the compactor's bigger brother, which happens to use the same bearing, they never got hot. That makes me think it...
JHG,
I know what you thinking, because I struggled with this too. At first glance, I thought constant speed meant no acceleration which meant no torque. And that is true, but a mass on frictionless bearings will consume no power once it is in steady state only if it is perfectly balanced...
This seems a little like elementary dynamics, but I can’t seem to find an answer anywhere in my recourses or on the web.
I work for a company that, among other things, makes vibratory plate compactors that mount on the end of backhoe booms. The compactors have a single eccentric mass that is...
There are manufacturers that sell hydraulic winches. In the applications that I am familier with they are driven by the power steering pump and use a two-position valve to divert oil to the winch. Take a look at Mile Marker's website.
If you could find a used pump then the only other things...
