Mobile Screw Conveyor, 7m, 9-25°

Last crawled date: 1 year, 11 months ago

This is an updated version and should, may, but most likely will not receive further updates.

Notes and tips:
- The main assembly; the file you should open is named "TRANSPORTER.CATProduct". It's in the .rar file. I suggest you extract it and put all the files into a subfolder and make a shortcut of this file next to that folder.
- The main dimensions are linked and you can make your own version of the conveyor by changing those. However, most of the dimensions outside of the base conveyor are not linked and you'll get constraint warnings if you change something (holes won't match, etc.).
Sub-assemblies "PrviOslonac" (First Support), "Dizalica" (Lifter) and "PogonV2" (Drive, version2) should be disabled for constraints to work properly.
- To change the main dimensions, click on the "f(x)" icon. Filter it to show only "Renamed parameters". "'ISO..." ones are bolts, nuts and washers from the "Catalog Browser".
- Change the filter to "Length" to see which constraints are dependant on which dimensions.
- The conveyor is intended to be adjustable in angle between 9° and 25°. Anything more or less would not be not possible in real physics. The "KucisteDizalice" (Housing of the Lifter) part is fixed. The front wheels and the bottom of the lifter are linked to the same plane. This is considered to be the floor.
- There are no animated constraints.
- Some components don't have detailed interiors (end bearings, drive), but their mass should be close to real (if anyone is bothered about it).
- Loading the assembly and/or updating it(refreshing) can take a few seconds/minutes, depending on the speed of your computer.
- The model is saved in CatiaV5R21. If you want a specific file exported in a format another software can read, request it in the comments. It will probably take a few days for me to notice it, though.

- The main conveyor parts should have similar counterparts on martinsprocket.com. There you can find a catalog with US measurements. My conveyor is designed in metric.
- Thanks to GrabCAD user named mahesh ms. I used and modified his/her wheel geometry. The wheel is now made to fit a 32mm shaft and can contain a "K 32x40x42 ZWTN" needle bearing (SKF).
- Thanks to SKF for making their CAD geometry available as CATScript files.
- The drive model is based on "VAR 55/2 B3" design from varmec.com. It's a variable speed drive and transmission system. Adjustable even when it is not running. +1 to the one who invented that.
