  23. Hello everyone I'm having a bit of trouble figuring out what would be the total output torque of both rated and peak for this chart with the gearbox. http://www.anaheimautomation.com/products/brushless/brushless-gearmotor-item.php?sID=158&pt=i&tID=98&cID=47&item=BLWRPG232S-36V-4000 Below the chart says "Torque of the output shaft (after gear-box) = (Peak Motor Torque) X (Gear Ratio)", but what would be the rated torque? (There's also two peak torques, one on both tables, but I'm guessing we use the peak of the first table. So then what is the peak torque on the second table representing?) This website also has a spec sheet which has a different chart than the one on the website which is also confusing. Thank you
  24. As I see this club (Kinematics of Machines Club) sit here and do nothing, I am reminded of other clubs from long ago. When I was a small boy, long, long ago, clubs were very popular. The typical "club" would start when several guys would build a "club house" in someone's yard. It was usually just a lean-to type structure, often a roof and one wall up against a garage wall or a fence, but it was to the center of all our activities. We would usually work feverishly for the better part of a day building the "club house." The wall and roof might very well be cardboard, a few tree branches, maybe a piece of corrugated sheet metal. We put a lot of ingenuity and effort into building our club house! Once it was finished, the big question always came up: What are we going to do now?? Sometimes, it would be proposed that our purpose was to fight other gangs in town. The biggest problem with that was, there were no other gangs that we knew about, so who could we fight? Along with that, there was always the risk that we might get hurt, perhaps even loose the whole fight and get beat up. Most of us were rather risk adverse! So, what were we going to do now? The only unifying thought that always came up was this one: We were going to keep the girls out (remember, this is a group of boys, roughly 6 to 10 years old!). Keeping girls out was obviously a priority, but we usually thought that an exception should be made if anyone's mother wanted to come in. Remember, mothers are not girls, even if there is some similarity, or so a group of small boys would reason. The whole thing would usually end when the father of the home where the club house was built would say something like, "I want this mess cleared away by the end of the day on Saturday." A few of us would dismantle the club house and pile it with the trash to be carried away while other members of the club simply vanished. With all the current activity in the Kinematics of Machines Club, and with its evident lack of purpose, I think I see a lot of parallel with the clubs of my childhood. The question in my mind now is, "When will we get the order to clear this mess away?" DrD
  25. Hi all, Very glad to find this forum, I hope it'll be the right place where to find answers. I'm looking for a system as the title says to control a rotary movement, the system must have both a spring and a dashpot. If someone knows any manufacturer, please, let me know. Thanks all
  26. Dear Bob, What you have drawn is simply a form of a slider-crank mechanism, and well known mechanism described in countless sources. Do a Google on that name and you will find more information than you ever imagined. DrD

  28. Gears on the transmission of a reacecar

    Why is the final gear on the transmission of a race car a spiral bevel gear instead of a straight spur one? Thanks
