Hi all! I would like to know how, in workshop practice, one would measure the tooth thickness and pitch of a spur gear?

I discovered that I asked a silly question. The winder is not going to record how many turns the handle retotate but the 30 teeth gear...So the label should really be marked "1000, 2000, 3000, 4000.etc" I think I now understand the entire mechanism. But I still don't quite understand the...

yes. I see what you say now. Thanks. But could you refer to the new thread created? It is a follow up of this.

yes. The two gears are directly located behinr the counter face. Please refer to the new thread I've created.

oops.. I just knew that I could post pictures in the 'reply'.. sorry for starting another thread... Please relocate this thread if any inconvenience is caused.

Hi all! I open a new thread since I am going to post another picture, and this would overload the old thread. The first picture shows the number of teeth of the meshing gears. I was wrong that the pair of worm gears are glued. They are not glued as mentioned by Q_Goest. And the two gears...

can anyone help? Is that I decsribed the probelm too badly? If yes, please point out where you think the problem is vague, and I would clarify them. Please kindly help.

Hi all! I have a problem about the gears used in a winder as hown in the picture. You can see right in the front view of the picture, there is a counter, which is a pair of worm gear. The engineering drawing of this pair of draw is as shown in another picture. My question is, in the...

Hi all! Thanks for suggesting some good fluid mechanics and thermodynamics books. I've borrowed them from my library and going to read through then. I would soon need to run a practical project on designing gear boxes. The bad thing is that I am really an idiot in those machine components...

I'm a mechanical engineering student, and I am required to learn PDE as well.

Hi all! I'm an undergraduate student. I'm going to consolidate my what I've learned in fluid mechanics and thermodynamics. I would like to pick up a nice book and read through it from the beginning.(learning from the very basic) So, I would like to know what books you would recommend?

Clausius2, did your improficiency in those hands-on skills hamper your research and the rest of your study? p.s. Ph.D in Aerospace! Really great! :smile:

thank Clausius2 and brewnog! It is really nice to hear you talking about your own experience!

Lots of thoughts come to my mind recently... I'm an undergraduate in mechanical engineering. I would like to pursue further studies and hopefully get a Ph.D if possible. I would said I am a bit like a theorist-type person, a bit crap in mechanical skills. But I am doing very well in simply...

Hi all! I am currently doing a mechanical engineering degree. I am considering to further my study after graduate and hopefully get a lecturership in university. It would be fantastically great for me to be a researcher in this field. But I am doubting my own ability and my inclination. I...
