  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    Travelling from Squamish to Calgary?

    Thought I would post here...you just never know. I'm trying to get 5 discontinued fence panels from Rona Squamish to Calgary. (Or somewhere closer to Calgary). They measure 95-1/2" W x 12" H x 1" thick. Not too sure of the weight, but guessing each panel would be 30 - 40 pounds. Willing...

    Helical cut gears - design solutions for lateral forces.

    Also, can anyone explain the purpose of having bearing sheilds/seals inside and oil filled gearbox? I would think these would not be needed.

    Helical cut gears - design solutions for lateral forces.

    @Mcgyver, I did read up on the Bellville washers. Looks like a great idea, but I can not find any in a 6004 or 6005 bearing size that would fit into the 0.014" I have available. In my reading about them I did read that it is preferable to load up the outer race of the bearing. No...

    Helical cut gears - design solutions for lateral forces.

    Basically I would be doing the same thing, shimming the shaft to one side, but the shim would have a bit of "flex" for lack of a better word? I'm not sure if I could get one thin enough? Presently I have ~0.015" play. Even if I could one thin enough, do you think it would last? I have...

    Helical cut gears - design solutions for lateral forces.

    Ok, that makes sense. I am unable to measure the play on the center gear. Maybe with some clay and preloading either the input or output gear to get the center gear to shift to its extreme I could get a rough estimate. My idea is to shim the input shaft to the left. Shim the output shaft...

    Helical cut gears - design solutions for lateral forces.

    It is power on/off ......but it does reverse the gear box loads.....not the direction of rotation.......when the power is on the motor feeds the gearbox and drives the back wheel. When the power is off the back wheel drives the gear box (Reverses the loads on the helical cut gears. Gears are...

    Helical cut gears - design solutions for lateral forces.

    Herringbone cut gears or dual helical cut gears should cancel out the lateral forces. The gears are about 10mm thick. Might be a challenge to cut something like that. Straight cut gears would also remove the lateral forces, but then I'm trading one noise for gear noise.

    Helical cut gears - design solutions for lateral forces.

    Maybe a video will help you guys see what I'm up to. Here is a short clip of the driveshaft from this gear box. Under power you can see the helical gears pull the shaft to the left. When you release power and the back wheel drives the gearbox the shaft moves to the right. There are three...

    Helical cut gears - design solutions for lateral forces.

    It is something that already exists. I'm thinking I might be able to shim the bearings on one side to remove some of the lateral play in the shafts, but for some reason I think this will cause an issue with the meshing of the gears. I'm even thinking that only shimming the input and...
