Hi all,
The attached pictures was given to us by my employer, I asked them if it's ok to share and they were ok with it since they are not the original producer of the information.
I had a little bit of debate about this with my co-workers, a few said in this particular example it doesn't not...
Hey everyone, if you look at the image, you'll see two similar designs, the main idea behind these two was how the shaft in the right hand design is cheaper to make since compared to the gear shaft in the left picture a large shoulder was eliminated and replaced by just a washer/spacer which...
Hi everyone,
We use a lot of aluminum in our projects. Our general practice is to use steel flat washers under the head (we mostly use socket head cap screws) to avoid leaving indentation marks, or damage the surface during tightening and that seems to be working well.
However, we don't use...
Hi Everyone,
The first picture (taken from a book titled "Power Mechanisms of Rotational and Cyclic Motions") shows a deep groove & cylindrical roller bearing combination acting is locating-side of a bearing system. The roller bearing supports only radial load and the deep groove ball bearing...
Hi eng-tips,
As you see in the pictures, I have a design (basically, a cross-section of the drive end of a simple conveyor). When my boss reviewed it, he recommended using a bearing lock nut on the right-hand side (so right after coupler, pressed against the inner ring of bearing). He said that...
Hi everyone,
Hope it's not a stupid question![neutral]
Let's say you have bolted connection and the bolts are preloaded to the recommended value (let's say to 75% of proof load) and the joint is working properly under the external loads applied to joint.
Now let's swap the bolt with much...

Hi all,
If you are to add two dowel holes to two plates that are going to be clamped together with M6 screws, what size of dowel you would use? 5mm? 6mm? 8mm? and Why?(assuming they are not under any shear force).
Not just from functional point of view, but also manufacturing, assembly? One of...
Hello everyone,
I have a welded table with all the mounting pads on the top Blanchard Ground to 0.005".
My first question is:
I assume specifying a parallelism tolerance on mounting pads (relative to datum A on floor pads) is complete waste of money since the table will be sitting on uneven...
Hi,
I'm a solidworks user, just started working on NX. I can't figure this out by myself. How can I connect the end point of the green curve in the picture right on the circle from previous sketch?
If I first sketch the curve then sketch the circle and use on-point relationship it works...
