These helical gears are also known as spiral gears. SECTION 7: SCREW GEAR OR CROSSED HELICAL GEAR MESHES Helical gear equals the integral multiple of radial pitch. In the axial system, the linear displacement of the helical rack, l, for one turn of the The radial pitch and the displacement could be modified into integers, if the helix Of the radial pitch, p t, and number of teeth.Īccording to the equations of Table 6-7, let radial pitch p t = 8 mm and displacement> The displacement of the helical rack, l, for one rotation of the mating gear is the product To mesh a helical gear to a helical rack, they musthave the same helix angle but with opposite hands. Normal coefficient of profile shift x n = 0. The formulas of a standard helical rack are similar to those of Table 6-6 with only the Similarly, Table 6-7 presentsĮxamples for a helical rack in the radial system (i.e., perpendicular to gear axis). With normal module and normal pressure angle standard values. Table 6-6 presents the calculation examples for a mated helical rack Viewed in the normal direction, the meshing of a helical rack and gear is the same asĪ spur gear and rack. Table 6-5 presents equations for a Sunderland gear. The only differences from the radial system equations of Table 6-3 are those for addendum and whole depth. The radial pressure angle, α t, and helix angle, β, are specified as 20° and 22.5°, respectively. For more information, go to Ellen’s website or her author central page.Table 6-7 6.10.3 Sunderland Double Helical GearĪ representative application of radial system is a double helical gear, or herringbone gear, ![]() Her WIP, The Hobo Code, is a YA historical fiction novel. Buikema has written non-fiction for parents and a series of chapter books for children - sprinkling humor wherever possible. Success!Īuthor, speaker, and former teacher, Ellen L. Go back to /CreatorHub, pressed upload video, and rechecked the sales page. The wait is 24 to 48 hours, although I suspect it may be less.Īfter more than enough time I checked to see if the video was on the sales page. ![]() The screen reverted to the select a category for your video as if you were getting ready to upload another one. Just to see what happens, I clicked on Upload video while it is still processing. Since this is the case when I scrolled down, I saw the Charlie’s New Beginning video short that I had uploaded for the physical book. This is the second time I’ve uploaded Charlie’s New Beginning as the first one is attached to the physical book and I wanted a video for the Kindle version as well. I didn’t have a lot of luck with “Your uploaded videos” so I went to /CreatorHub and this is the screen that pops up. As stated on this screen, you can view and manage your videos by going to “Your Account” and then selecting “Your uploaded product videos.” Give it a title and description (optional) and press submit if you are satisfied with the video. In my case it is Charlie’s New Beginnings. Decide how you want your video categorized. Click on “Upload your video” (see above). ![]() If you have the capability, this is what it will look like: Click on any image to enlarge Please note that not everyone is seeing this option on their books’ pages yet. I state upfront that technology and I do not always have an easy relationship, but this looked so promising that I thought I would give it a try. While perusing Facebook, I noticed a post in the Indies Unlimited Fans Group that piqued my interest - the new “add your video” option for your book’s Amazon sales page.
