Yes, it would be easier to drill the hole but there are other reasons. It's makes the shaft the same width as the red bearing also clamped by the green sides. The shaft will experience torque when the knob at the top is tightened. A hole though a round shaft would have high pressure on the curved edge at a point on each side some little distance away from ...

If the screws look like a pair of thick and long interlocking archimedes screws, then the device is called a rotary screw compressor. You can think of it as a special case of a roots blower, where the interlocking lobes on the lobe shafts possess a spiral twist. By making the lobe depth progressively shallower along the length of the screws, the working ...

The impulse causes lateral acceleration of the rod and rotation of the rod. $$ P=m\frac{dv}{dt} \quad \text{for lateral acceleration}$$ $$ P=I\frac{d\omega}{dt} \quad \text{for rotational acceleration}$$ We calculate the net acceleration for each point along the length of the rod and after multiplying that by the density of the rod we get the forces' acting ...

That is on the high pressure end of normal pneumatic conveying blowers, but they are out there. See the notice at the bottom of the attached chart. http://www.hsiblowers.com/products/high-speed-turbo-blowers.html You don't want a high pressure compressor, you just need to find the right compressor that will deliver at 18 psi. You need to specify if the ...

Here is the cheap way to proceed. First, find you a battery-powered weedeater that is second-hand, or a discard. disassemble and test the motor for operation. If it operates, now you have a generator that has almost exactly the right power output for your application, because in its previous lifetime it was a motor in the same application as the little gas ...

In general, either grating configuration should permit flow equally as well provided the slot diameters are the same, and the ratio of open area is the same. By fins in the acrylic, I assume you mean slots correct? Aluminum fins on the heat sink, slots in the acrylic housing, the acrylic material between the laser cut slots are members (slang for structural ...

Some threaded inserts have flanged faces for a few reasons, one being that if you press the flange flush to the surface around the hole you're tapped hole will be relatively perpendicular. These can just be hammered in. Others, typically "self-clinching", are installed with arbor presses and some degree of attention by the operator to maintain ...

The methods available to a hobbyist are akin to that of the production world, in that one needs only a controlled heated implement traveling in a restricted manner. A drill press with a long bolt threaded to match the insert provides such restrictions. Heat can be applied to the insert and the quill lowered into the part, which is secured appropriately to ...

Figure 1. Something like this? It will be faster as the drive pin moves through the lower section of the slot. Figure 2. This option should result in more even speed on the forward and reverse strokes.

Rotary screw and scroll , neither uses centrifugal force. Sullair Co. makes both and other types of compressors . Their website should have more information.

A 1 cylinder 4 stroke at 3000 rpm will have 1500 power strokes, So 1500 * 3 is 4500 power strokes. Based on a 4 stroke engine needing two crank revolutions to complete the full cycle of intake, compression, power and exhaust.

The trade numbers typically give you the envelope dimensions (inner and outer diameters, thickness). Everything else is at the discretion of the manufacturer - pitch diameter, rolling element size, quantity and contact diameter. This is why for the same trade number bearing you might see several different manufacturers, all with different load ratings.

I've never seen a machine do this, but consider this. Tie the thread to the middle of rod and have the rod in a vertical orientation. Have two jaw like, or pincer like devices, one vertically above the other. Place the rod, with thread attached, into the one of the sets of jaws, say the top one. As the chain of toruses moves laterally the top jaw moves ...

The duplicate activity H should start from the end of activity G. otherwise you are stating that the duplicate of H can only start once H is completed... The duplicate of activity K starts from the end of activity F. When checking these diagrams, you just have to read the story in the diagram back to match the information in the table. If you list some of ...

What I've seen in commercial applications of this nature involve a vibrating device, which dislodges the stuck balls. It causes random movement within the block or pack of balls and helps to disorganize them enough to allow movement. From the video clip, you'd want something to move the block in the center out of the way, even just a tiny amount. Have you ...

Since certain projects for certain tasks can be composed speedier than the time it takes to create an identical CAD document. Likewise, utilization of factors makes the program more helpful ie a program to create a chamber can be composed to accept width as the controlling contention while delivering numerous CAD records for different various measurements ...

If you operate a cnc machine you will learn g-code eventually. Even if its just a subset of the g code. The reasons are numerous but mostly it boils down to: You need to setup the machine and tools from time to time. Then it might be practical to be able to write short snippets to change tools, work coordinates etc. I mean this isnt really magic its more ...

I'm afraid joints created in the editor don't transfer to the Animation module. You have to animate the components again.
