    Standard for Metal Bottle/Cylinder Formed Threads

    Hello, I am trying to develop some attachments that will thread onto an existing tool. The attachments are metal cylinders. The existing one that I am examining is shown in the picture below. I am trying to find the thread size of this cylinder so I can model and tolerance it correctly...

    Help sourcing an internally threaded vulcanized hard fiber seal

    The thread is 5/16-24 UNF. No thread sealant is permitted unfortunately.

    Help sourcing an internally threaded vulcanized hard fiber seal

    The washer pictured is brand new. It comes with the thread in the inner diameter from the manufacturer. I do not know the original manufacturer though. When I say it appears to be formed, I mean it appears to be formed into the material, instead of being tapped afterwards. The material looks...

    Help sourcing an internally threaded vulcanized hard fiber seal

    I am trying to source the washer seal in the image below. It is .41" OD x .29 ID X .067" thick. The unique thing about this washer it appears to have a thread formed into the ID. I have reached out to every vulcanized fiber / hard fiber material supplier I can find and no one can make this. Does...

    Reduce Noise and Vibration of Planetary Gearset

    Here are some videos to compare the sound/vibration with and without the gearset. Tool with the gearset at max rpm: https://res.cloudinary.com/engineering-com/video/upload/v1706111268/tips/WITH_GEARSET_-_MAX_RPM_ispuc1.mp4 Tool without the gearset at max rpm...

    Reduce Noise and Vibration of Planetary Gearset

    3DDave, Thank you for your reply. I should have mentioned that I did run the tool with the gearset installed and not installed. The vibration and sound is greatly reduced without the gearset installed, as I perceived it. I do not currently have any means of measuring the vibration. What...

    Reduce Noise and Vibration of Planetary Gearset

    mfgengear, I have not determined the hardness or material requirement yet. I want to confirm, from the pictures I posted, you believe the issue lies in the quality of the gears themselves? This is a concern of mine. As I looked at the teeth under the microscope, I did see that they shapes are...

    Reduce Noise and Vibration of Planetary Gearset

    I am wanting to improve a planetary gearset in a cordless power tool. The current gearset creates a lot of noise and vibration. The motor spins at ~17,500 rpm, and the planetary gearset reduces it to ~4000 rpm at the output. The gear ratio is .228. The sun gear has 13 teeth, fixed ring gear has...

    Need Data Acquisition for Pressure, Sound, and Vibration of pneumatic hand tools

    MintJulep, Mass flow rate is another test I will be doing. The results of the test is for our own R&D. The test will be a comparison of our product and others in the market.

    Need Data Acquisition for Pressure, Sound, and Vibration of pneumatic hand tools

    I am sorry for the vagueness before. I have thought about this testing more and what I would like to do is be able to measure the output of the pneumatic tool, a caulking gun, compared to the trigger position. Ideally the caulk would output linearly with the position of the trigger. Ideally, I...

    Need Data Acquisition for Pressure, Sound, and Vibration of pneumatic hand tools

    I am a new engineer at my company and I have been tasked with setting up a way to measure the pressure limits of a new pneumatic tool that we are working on. I also need to measure the sound produced from the tool, and the vibration that the user would experience in their hand. I am a recent...

    Improving pipe threads on LDPE injection molded component

    3DDave, I don't think the material is the issue because products like this already exist and have existed for a long time: example: https://www.adhesivedispensing.net/TS616_Nozzle_6_x_1_16_pk_10_p/ts616.htm I believe it is most certainly the thread form that is the issue, and I am trying to...

    Improving pipe threads on LDPE injection molded component

    btrueblood, I should have stated that it is "more play than desirable". The existing products we are comparing it to feel much more secure as they are being tightened. No sealant will be used to seal the threads, as they are supposed to be quickly interchanged. Using thread gauges is one of my...

    Improving pipe threads on LDPE injection molded component

    btrueblood, It has both axial play and lateral play. I believe that when the two components are fully tightened, that only 1 or 2 threads are actually engaging. In testing, when we put the system under pressure, the male threaded component blew off of the female threaded component. There is also...

    Improving pipe threads on LDPE injection molded component

    Hello, We recently designed some LDPE components that 1/4" NPT pipe threads. One component with internal threads and what component with external threads. We had molds made and received initial samples. When tightening components together, the thread engagement feels sloppy. Before the...
