Anyway, the company I will be working for makes both types of gears, inveloped and 'standard' gears.Hot Threads. What version of Solidworks are you using? Let me know if you have questions on how it was created.įor some reason I can't open that picture you attached, maybe I will be able to at work once I start up there. Ill try to draw an example when i get a moment. More than likely you will need a straight line for the centerline. The picture you posted is a little more complicated but because it is an enveloping style worm gear setup but you just need to draw your profile of the gear and a sweep path. The tooth profile will depend on your design but the pitch of your helix needs to match the pitch of your gear.
I put a lot of links in there for suresh about gear design and a few how to links in there.
Switchblade, check the post above this one one designing a gear. I found this thru some of the related threads. I just watched this video very closely, and am definitely a LOT better than where I started. I have Solid Works Here is one that I made real quick, but it does not have the proper angle to fit into the worm. I will be on here periodically to try and help you guys help me. Mainly the worm gear, but just some background advice on how to make these better, faster, etc. Hello everyone, I am fairly experienced with Solid Works, but would like some advice on how to create both of the gears in this picture. Note: I added some cuts and fillets to add character to my gears.įigure 3 - Finished Gear.By Switchblade, July 10, in SolidWorks. Now you have a part that was created by the toolbox but is no longer governed by it. This path may change depending on your installation. This allows you to do a Save As on the part file, and save it to your project folder. Uncheck the box called Make this folder the default search location for toolbox components.
The toolbox will override any changes made to a toolbox part, but I think the default Toolbox gears are ugly. Using the gears we created, the gear ratio will be or Toolbox files are read-only. Because tooth count is proportional to the size of the gear, you can also use the number of teeth to calculate the gear ratio. Figure 2 - Calculating the center-to-center distance. First, divide them in the individual diameters by two to get the radius. With the pitch diameter, it is easy to calculate the center-to-center distances of the gears. If I have another gear with 20 teeth, and the same diametral pitch as above, the diameter will be four inches. Toolbox Gears – Kinetic Art Project Part II So, if I have a gear with 30 teeth and a diametral pitch of five teeth per inch, the diameter will be six inches. The diameter of the gear will be the number of teeth divided by the diametral pitch. Obviously, the tooth count is the number of teeth on your gear this number will govern the size of the gear. Solidworks Tutorial Very Simple Worm Gear For Toys Figure 1 - Two gears that are the same size with different Diametral Pitch. For my gears, I wanted nice large teeth, so I chose a smaller diametral pitch of five. Larger diametral pitch numbers result in smaller gear teeth. What this means to non-engineers is that so long as two gears have the same diametral pitch, they will properly mesh. Diametral pitch equals the number of teeth divided by the pitch diameter the result is the size of the gear tooth independent of the size of the gear. Thank you for returning to my Kinetic art project series.
