Fully 3D-Printed Planetary Bevel Reducer
This wonderful mechanism is similar in principle to the planetary reducer, but instead of the regular spur gears it employs bevel ones, and the gears in the middle are tilted. When projecting the pitch cones of these bevel gears on a vertical plane, their triangular outlines combine to create an isosceles trapezoid that is completely filled.
The gear ratio for this particular model is 4:1. The model's diameter in its widest part is 20 cm (7 7/8").

How to Derive the Equations of 3D Surfaces of Arbitrary Complexity and Model Them in Blender
Просмотров 6 тыс.Год назад
3D surfaces can be defined parametrically, with three functions x(u, v), y(u, v) and z(u, v). While the parametric equations of simple surfaces such as a cylinder or sphere can be easily derived with just a pencil and paper, others, such as a spinning hypocycloid orbiting around a center which itself is rotating, seem impossibly complex. This tutorial provides a system and method for deriving t...

How to Model a Tricky Part Based on a Technical Drawing in Blender 2.9.
Просмотров 16 тыс.3 года назад
The drawing, which we downloaded from GrabCad.com, poses a number of challenges. Specifically, it contains multiple joints between straight and cylindrical surfaces, as well as cylindrical and other cylindrical surfaces. The tutorial begins with the solving of two geometry problems necessary to model this part, and then proceeds with the actual modeling, which is not a quick undertaking. We had...
Tutorial: How to Model Non-Circular Gears in Blender
Просмотров 13 тыс.4 года назад
This tutorial briefly explains the math behind non-circular gears, and demonstrates how to quickly design and test a pair of meshing non-circular gears in Blender 2.81 (earlier versions of Blender can be used too.) All gears are fascinating, but there is something especially mesmerizing about non-circular gears. The math behind them is not exactly trivial, but we have developed an online calcul...

In this tutorial, you will learn how to design a gear train with a given gear ratio (1:12) and specific position of the output shaft relative to the input shaft (input and output axes coincide). A simple python script (shown below) is used to pick the optimal number of teeth for each of the involved gears based on the given constraints. Some neat tricks are used to turn a gear contour to a soli...
Tutorial: The Math Behind Hyperboloidal Gears and How to Design Them in Blender
Просмотров 14 тыс.5 лет назад
Hyperboloidal gears are essentially regular spur gears with their top and bottom twisted in the opposite directions. A hyperboloidal gear's reference surface is a hyperboloid, which is a surface obtained from a regular cylinder by twisting its top and bottom. Two identical hyperboloidal gears are capable of transmitting rotation at any angle between 0° and 90° with the gear ratio of 1. This tut...

    There are three main configurations of planetary gear systems: 1:planetary, 2: solar, 3:star. 1: Planetary type (internal gear fixed, sun gear as drive shaft, planetary carrier as output shaft): Gear ratio = number of teeth of sun gear / number of teeth of internal gear Example: For 12 teeth sun gear and 60 teeth internal gear, gear ratio = 12 / 60 = 1/5 2: Solar type (sun gear fixed, internal gear as drive shaft, planetary carrier as output shaft): Gear ratio = number of teeth on internal gear / number of teeth on sun gear Example: For 12 teeth sun gear and 60 teeth internal gear, gear ratio = 60 / 12 = 5 3: Star type (planetary carrier fixed, sun gear as drive shaft, internal gear as output shaft): Gear ratio = (number of teeth on internal gear / number of teeth on sun gear) + 1 Example: For 12 teeth sun gear and 60 teeth internal gear, gear ratio = 60 / 12 + 1 = 6 Therefore the gear ratio is 1:6 in the case of a *star type (fixed planetary carrier, sun gear drive wheel, internal gear output shaft).

    "remove doubles" is now "mesh->merge by distance." "Spin" is "mesh->extrude->spin." Blender key bindings change regularly so "Press W" is not very helpful (is now 'edge->bridge edge loops'.
