spur gear collection 02 3D 打印模型

spur gear collection modeled in inventor 2010 and provided in multiple file formats (.ipt, .stp, .stl, .3ds, .obj). collection includes 14 spur gear sizes (8-tooth through 64-tooth), fully ready for 3d printing.

the native inventor files are fully parametric and can be opened and manipulated in any version of the software that is 2010 or newer. the feature trees and parameter tables are logically arranged and clearly labeled, making edits extremely simple.

all gears have been exported as stp files, allowing them to be opened in any 3d cad software. they have also been exported as 3ds and obj files, for use in 3d graphics packages. finally, they are provided as stl files, making them ready for 3d printing.

strategic recesses have been engineered into the larger gears to minimize their volume for the purpose of reducing the cost of 3d printing.

no textures or materials included. model is not animated.

gear specifications:
- approximate involute gear tooth profile
- minimal backlash between gears
- 1/4 inch face width
- 1/4 inch shaft bore
- 16 pitch (p) gear size
- pitch diameter (pd) = gear teeth (t) / pitch (p)
- outside diameter (od) = pitch diameter (pd) + 0.125 inch
