help!!

[jbelle7435]

This is my last part to create am done with my final project!


I need to make a pinion shaft


12 Teeth 20 degress STUB-12P PITCH 1.000


I need help on designing pinion gears in PRO-E???Anyone could help would be very appreciative!

Are you making a pinion gear, a pinion shaft or do you need both and then assemble them?


Generally, the gear and shafts come seperately so you can utilize a fixed shaft diameter and a vary the gear size.


Creation of the shaft could be as simple as a revolved protrusion of a given size. As for the gear itself, I would start with a revolved protrusion of the dimensions you are given or have calculated. Next, create a datum plane at an angle from on of the default planes through the axis of the protrusion. Sketch the profile of 1 (one) tooth symetric about the datum plane you created. Pattern that tooth,using the angle of the datum plane asyour basedimension, evenly spaced around the 360 degree circle.


Good luck.

A correction to previous post: you do NOT need to create a datum plane. In the sketch of your tooth profile, create acenter lineat an angle from one of the datum planes. Sketch symetrically about this centerline. Then create pattern using that angle.


A word of caution, dimension from the center of the axis for easier pattern creation.

Well what this really is .......


1)RAM---------->(22 teeth 20 degree STUB-12P)


this looks like a bar with 22 teeth going down it. I created that


2)Pinion Shaft-->(12 Teeth 20 degree STUB-12P, PITCH DIA 1.000+-.005)


I am desigining an arbor press. As you pull a bar downwards that is connected to the pinion shaft,the pinion shaft is spining so its teeth are going against the RAM's teeth making the RAM going downwards against it. If you understand

There are downloadable gear models in the files section at this site. Here's a link to one that will probably work for you.

Just modify the parameters to your needs. Also helps to see how gears can be constructed.
