Gear Design & 3D Shapes 2.2.5

  Continue to app

Publisher Description

The app allows you to design and visualize the involute Gear,Pinion and Rack geometry in 2D and 3D. In built functionality includes saving of designs on to your device to view anytime. The geometry generated is reliable.

[IMP Note]App doesn't work well on Tablet due to UI issues.

Design available based on:

+ Pinion & Gear Teeth and Module

+ Teeth and Module

+ Teeth and Base Diameter

+ Teeth and Tip Diameter

+ Free form (No design restriction)

The app has got functionality to share the design along with all the design data over, email, What's App etc.

About Involute Gears:

The involute gear profile, originally designed by Leonhard Euler,[1] is the most commonly used system for gearing today, with cycloidal gearing still used for some specialties such as clocks. In an involute gear, the profiles of the teeth are involutes of a circle. (The involute of a circle is the spiraling curve traced by the end of an imaginary taut string unwinding itself from that stationary circle called the base circle.)

Irrespective of whether a gear is spur or helical, in every plane of the involute gears the contact between a pair of gear teeth occurs at a single instantaneous point (see figure at right) where two involutes of the same spiral hand meet. Contact on the other side of the teeth is where both involutes are of the other spiral hand. Rotation of the gears causes the location of this contact point to move across the respective tooth surfaces. The tangent at any point of the curve is perpendicular to the generating line irrespective of the mounting distance of the gears. Thus the line of the force follows the generating line, and is thus tangent to the two base circles, and is known as the Line of Action (also called Pressure Line or Line of Contact). When this is true, the gears obey the Fundamental Law of Gearing.

The angular velocity ratio between two gears of a gearset must remain constant throughout the mesh.
