Tutorial: How to model involute gears in SolidWorks and show design intent.

May 19,  · Step 1: 1) Make a sketch with a circle on the front plane. This represents the pitch circle that defines the centre of the tooth in radial direction. Dimension it. I chose a Pitch diameter, P=76 mm, but obviously you can choose any value. Aug 03,  · 9- SolidWorks Gear Tutorial: Gear design & drawing "easy version", type: spur gear.

Welcome to SolidWorks tutorials for beginners and in this Solidworks exercisesyou are going to learn to make gear 3D model. It contains the both video and step by step pictorial explanations for creating different types of gear Spur gear, helical gear bevel gear etc in the graphics area of teetn CAD software. You will see how to use How to connect denon bluetooth headphones features and sketch tools in simple manner to create Spur gear 3D too.

Also see How to make Spring 3D Model. Before going to this solidworks tutorial, you should have some knowledge about the gear, its types and major uses in engineering. Gear or Gears are toothed wheels which helps to transmit power and motion of one shaft to another by means of engagement of its teeth. The power transmission is very effective which gives positive drive and have constant velocity ratio.

Gear box is very compact in construction due the relatively small distance between drive and driven shaft. Note: Drive shaft means which is directly connected to drive machine e. Gears are well capable to huge amount of power transmission as compared to chain and belt drives.

You can achieve speed reduction even in small range which is cannot achieves by using chain or belt drives. These are the some of advantages of gears. Construction is very compact because of that manufacturing cost is also high. It solidworsk needs perfect alignment of shafts to provide efficient power transmitting capability with less loss and vibration. Teeth of spur gear is cut parallel to the axis of the shaft and so it is also called straight toothed gear. Because of the teeth alignment, you can use what is the biggest volcano in hawaii when the drive and driven shafts are parallel.

If you draw the profile of spur gear, it looks like an involute curve. In helical soliidworks, the teeth is cut an angle to shaft axis and profile is involute which is similar to spur gear. Hleix angle of both drive and driven gears should be same and one of should be right hand and other in left hand direction. Bevel gear is seem like truncated cone, where the gear tooth size and thickness decreasing towards the apex of the cone. It enables the power transmission in 90 degree where shaft what does p mean in emoticons are intersecting.

Bevel gear have two types of tooth cut which are either straight or spiral cut. Worm gear is different from other gear which consists of a worm and wheel. It enables 90 degree power transmission, where shafts axis are not intersecting. Worm is just like threaded screw which engages with tooth of worm wheel. Main specialty how to draw gear teeth in solidworks this gear is high speed reduction ration as compared to other gear types. Read more in wikipedia. Let us see how to create different types of gear 3D models with video tutorial and step by step pictures.

Open the SolidWorks solidworkx New part File. Select the Plane e. You can select it from the Tools menu also. This is the dedendum circle of gear. And you have to give dimension as per your requirement using Smart Dimension tool. Here, it is completely dimensions are selected roughly and only for solidworks tutorial purposes. You can apply it by clicking right mouse button and select the NormalTo from it.

You have to draw centerline using the Center line sketching tool. It should make it as closed loop for application of SolidWorks feature tools. Before applying circular patternyou have to make an axis for drive it. And click OK. Apply extrude cut option from the features command manager.

Final spur gear is look like the figure below. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.

What is Gear (Mechanical Gear)?

Jun 13,  · Teeth of spur gear is cut parallel to the axis of the shaft and so it is also called straight toothed gear. Because of the teeth alignment, you can use only when the drive and driven shafts are parallel. If you draw the profile of spur gear, it looks like an involute curve. Helical Gear: In helical gear, the teeth is cut an angle to shaft axis and profile is involute which is similar to spur gear.

The model from this tutorial is found here: Involute Gear Design from Scratch. This represents the pitch circle that defines the centre of the tooth in radial direction. Dimension it. The lines meet in the first point on the involute curve. This angle is called the pressure angle and 20 degrees is one of the most used standards, but it could be something else.

This circle is the base circle for the involute. As you may know, an involute is the curve described by the end of a string wound around a cylinder. You have to make it driven in SolidWorks because the length is fully defined by the sketch. If you change the sketch, this measurement will update to a new value. Draw a centerpoint arc as indicated. You click the two endpoints AND the arc itself, and the resulting dimension has a little arc over the number, showing that the dimension is measured through the arc instead of linearly.

This enters the value into the equation automatically. You can also draw a point offset the initial value 13 along the base circle to get the lowermost point on the involute. This needs to be fixed. Increase the length of the arc from 5 mm to say 5. Due to the parametric nature of the software, everything updates without you having to do anything else.

Extend the tooth downwards with lines parallel to the normal construction line. Specify 38 instances, equal spacing over degrees and click OK. This gives an assembly with the gear wheel at the origin. Mate the temporary axis to the assembly top plane …. Now both gear wheels can rotate independently but they stay centered.

You can go backwards and forwards. We have designed involute gears and verified that they actually work according to design intent.
