Welcome Viewers. Thanks a lot for visiting. The videos available on this Blog cover the application side of Autodesk Inventor software. Full sketching and total part/assembly creation is displayed. Almost all the videos are with finished part/assembly files. There are lots of video tutorial available on internet but very few show full modeling process as well as provide the file used in the video. So grab this golden opportunity.
By watching these videos any one can observe proficient techniques that are applied during parts/assembly creations.
If you are a first time user of Autodesk Inventor we recommend you to take some basic training from else ware and then return back. Only users who have some basic knowledge of the Autodesk Inventor software can understand these videos, because we have not added audio narration with the video tutorials.
The files of 3D Parametric CAD models available here can be utilized as a practice models too, in the class room training.
All the videos available here are in High Definition (HD). So, video quality is sharp and clear. Our Mission:- Promote our skills to find appropriate job for us and help people involved in CAD (Computer-Aided Designing) field. Dear viewers if you think that the content provided here is valuable, please pass it on to your friends/colleagues.
Display motion in Helical Gear (Internal) through Drive Constraint.
Create a ‘New Assembly’ and save it with the name ‘Helical Gear (Internal)-Drive Constraint ’.
Hold the Ctrl key, and click the Spur Gear tool on the Power Transmission panel of the Design Tab.
The Spur Gears Component Generator dialog box will open with its default values. Under the common area, fill 20 degree in the Helix Angle input box and select the check box next to ‘Internal’. Click ok.
Click anywhere in the Design Window, to place the Spur Gear 1 and Spur Gear 2.
Align the model in correct position by using View Cube.
Make the Spur Gear Assembly flexible from the Browser Bar.
Open the Visibility of Z Axis of Assembly and Z Axis of Spur Gear 1 in the Browser; later apply a Mate Constraint between them.
Place a Mate Constraint between Centre Point of Assembly and Centre Point of Spur Gear 1.
Open the visibility of YZ Plane of Assembly and Z axis of Spur Gear 2; later apply a Mate Constraint between them.
Place an Angle Constraint between YZ Plane of Spur Gear 1 and YZ Plane of Assembly. In the solution field area, select Directed Angle option.
Turn off the visibility of Work Plane to make the screen clear.
Set the browser from Assembly View to Modeling View using the toggle at the top of the browser.
Select the Angle Constraint in the Browser and change its name as ‘Drive’ by clicking twice slowly.
Right click the Drive Constraint and select Drive Constraint Tool from the context menu.
In the Drive Constraint dialog box, set the End value to 360 deg.
Expand the dialog box and set the value for Increment 0.5 deg.
Clear the screen by activating the Clean Screen command.
Click the Forward Button to display motion in Spur Gear 1 and Spur Gear 2.
In external Tooth systems, direction of rotation is in opposing directions. Internal gears have a parallel direction of rotation and a small centre distance.
