Creating Spur and Helical Gears - Tutorial - SOLIDWORKS. This video shows not only how to create Spur and Helical Gears using SOLIDWORKS, but also how to add intelligence to the design and let SOLIDWORKS do most of the heavy lifting for you. This video relies heavily on equations. If you’ve never used equations in SOLIDWORKS, this is a great video for that also.

I have watched many videos on gear design and this video is by far the best explanation of how gears are designed and the use of equation tables to control size and number of teeth for a gear. The narrator speaks clearly, knows his subject and moves slow enough for viewers to follow the video. In my opinion the best tutorial on the subject I have ever viewed. Great teacher!

This is a great SolidWorks tutorial, with the one exception that these gears would explode in use. Gear teeth are nearly universally involutes, not circular arcs. SolidWorks even offers involute support. This can't be overlooked.

After the first impulse to agree, I googled it (but didn't get too deep into the matter) and found that actually the "Wildhaber-Novikov gearing" or "Circular arc gearing" seems to even have advantages over the common involute or zykloid teeth... But it is more complicated to manufacture - and so quite rare. Anyway I guess that if someone is constructing "gears", he is going to buy them as standard parts. Or if he really makes them himself - he knows about involutes ;)

this was the best gear design tutorial I have ever watched, so simple!

@jeandaher8757 9 жыл бұрын

nice tutorial for using the equation functionalities however as a mechanical engineer here are some major faults in the design: 1- by definition the involute is never an arc, it follows sin and cos formula 2- the pressure angle should never be done as shown, it simply used to calculate the base diameter where the involute starts 3- the helical angle is also wrong, simply projecting a line is so wrong, it should be done with a "helix", the helix pitch depends on the helical angle and pitch diameter, for instance for 45 degrees its tangent is 1 so the pitch is 3.141 * pitch diameter I didn't want to sound critical, but if you produce such tooth profile as indicated the gears will slide and won't roll. they won't be efficient at all especially for molding plastic gears. I have produced perfect gears geometries this way, it takes more time in the beginning but if you set your global variable as indicated it should be easy. I will be happy to share my knowledge with the community thanks

jean daher I had the same thoughts, jean. The method in this clip is wonderfully simple, and great for making realistic looking gears (as long as the "looking" is done from a distance) but it should be made very clear that gears modelled in this way are not functional. Most people will not realise that the projected curve, in particular, produces a different result from a helix, and it is increasingly incorrect as the helix angle increases. A "crossed" skew-gear pair at 45 degree helix angle would make this very apparent, and the interference towards the ends of the teeth would be considerable. A further problem is that, for a helical gear, the tooth profile needs to be swung around normal to the helix. Not that it matters for a "Not for production" visualisation of a gear.

+jean daher I am studying Design of Machine Elements, and one of my final assignment is to create a gearbox, which I have choose to use spur gear and I found your comments very accurate with what I am studying at the moment.Would you share how you have created perfect gear geometries? I am struggling at the moment in creating the shaft....

@jeandaher8757 9 жыл бұрын

Sure, but as I said it takes some time upfront. SW is also limited since it always refers to the original coordinate system and disregard the new one. (I complained abut it, they admitted it but still not fixed) 1. start setting an equation for 1a-pitch diameter 1b- diametral pitch (module for metric) 1-c pressure angle 2. make a sketch for all relevant diameters driven by the equation, from previous you can set your number of teeth, base diameter, addendum etc. 3. now create an equation driven sketch, make sure you pick parametric with t1=0 t2=2*pi (it doesn't have to be 2pi but it is better to be longer than not enough) set Xt=(base diameter/2)*cos(t)+(base diameter/2)*t*sin(t) set Yt=(base diameter/2)*sin(t)-(base diameter/2)*t*cos(t) you should have a full involute. after that just fix the curve, another bug with the software the rest is up to you to make an extrusion based on that sketch and cut based on equation curve, create the cuts pattern from calculated number of teeth. if you follow that you have a template that works perfect every time. once you master that helical gear is similar however you cut the involute with a helical cut instead straight cut. the helix pitch will based on helical angle described in earlier post hope that helps you jean

Dont forget that you can drop your driving sketch into every assembly and sub assembly, this lightens up the processing time in the main assembly and helps your computer to think in smaller chunks of information this helps stop crashes and opening and saving times.

just an FYI, the gear as modeled produced interference when mated with an identical gear of ~0.2mm according to interference detection features. It would not be functional. I verified the equation outputs to be sure it was not a replication error.

How do you calculate the center to center distance if you know what gear ratio and module you would like to have?

@anandi1974 10 жыл бұрын

I have the following points for clarification: 1.How to create gears with actual involute profile? 2. @10.15 the profile curves were dragged to meet the root diameter. However, for gears with less than 43 teeth, base circle would be bigger than the root diameter. In that case what do we do? 3. Profile used for creating the spur gear can not be used for Helical gear. The profile used for Loft cut should correspond to the profile in transverse plane and not the normal plane. I sincerely request you to make a detailed demo incorporating all the above mentioned points.

If the gears are on the same plane, what angle would you use if you are meshing helical gears?

@brunohougaard1758 5 жыл бұрын

This helical thing is all good, but ... if the derived profiles are not perpendicular to the projected curve, the tooth profile is being "squeezed" together as the helix angel increases, thereby compromising the profile and thinning the tooth along its width. - A better way would be to create the projected helix curve (as shown), creating a reference plane along (at the end) - and - perpendicular to the curve, and on here sketch the tooth profile and perform a sweep to preserve the integrity of the profile along the helix curve, no matter the applied helix angle!

Thank you for this great effort I have a question please answer me I used all the methods to draw the model and all the methods that I used I think are unrealistic. Generally The first question is do you think this method is the best for drawing gears??? If the answer is yes, then why does the width of the tooth appear to be wider than the reality if the number of teeth is less than 10??? The last question is, is there a law regarding the depth of the tooth? If the model is greater than 1.25, the formula is used [the model * 2.25] and the smaller one is [the model * 2.4], or is it worth experimenting??? Thank you

so looking through the comments a lot of people are saying this isn't mechanically correct. Would this spur gears design method be sufficient for prototyping out of acrylic or plywood with a laser cutter, or will they fail instantly? A lot of people have said things along the lines of 'this is wrong, this is what you should have done' but what I want to know is why it should be done differently. Is it simply more efficient, or is it an absolute requirement that these parts be produced differently? Thanks in advance for any replies.
