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 this CAD software. You will see how to use Solidworks features and sketch tools in simple manner to create Spur gear 3D model. 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 also 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 only when the drive and driven shafts are parallel. If you draw the profile of spur gear, it looks like an involute curve.
In helical gear, 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 axis 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 of 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 and 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.Camnetics, Inc. GearTrax provides the designer with an easy to use tool for creating solid models of drive components in seconds. Spur and helical gears, bevel gears, worm gears, involute splines, timing belt pulleys, chain sprockets, V-belt pulleys, cycloidal drive mechanisms and elliptical gears. GearTrax provides the designer with an easy-to-use tool for creating solid models of drive components.
It is intuitively easy to use for the designer with limited gear experience yet powerful enough for the gear expert. It is extremely useful in understanding how changes to the gear parameters reflect on the gear mesh. GearTrax is more than a library program. Each part model is created with its specific requirements just as a designer would create it, but rather than taking hours or days, the part is created in seconds.
GearTrax creates solid models of spur, helical, rack and face gears, bevel gears, worm gears, involute splines, timing belt pulleys, chain sprockets, V-b lt pulleys, cycloidal drive and elliptical gears. GearTrax also integrates with Excel to create data sheets. Annotating a drawings or part file is simple. Data sheets can be created in text, CSV and Excel files. Two versions are available, standard and PRO for higher functionality. The PRO version has a full screen mode.
Benefits Creates parts in seconds, rather than hours or days Intuitive and easy to use, yet powerful Helps the user understand how changes to the gear parameters reflect on the gear mesh PRO allows for modifying models created by GearTrax Very affordable.
Our gear and cam software products provide the designer with tools to create solid models of drive components in seconds rather than hours or days. GearTrax Data Sheet. Learn more. GearTrax Intro. A quick video introduction of the 3rd generation of GearTrax.

They are not true involute gears that you can use for manufacturing. Rack gears must have fewer than teeth. Parent topic Other Tools. Performing Beam Calculations.

Making gear on SolidWorks are easier than making gear on Autocad because we just need to put the parameter likes Pitch Diameter, Modul, Shaft Diameter, and etc. Look at the picture below :. Then choose and click the Gear twice. After that, the kind of gear choices will appear. Then click the Spur Gear and click the right side of the mouse then click Create Part. After that, there will be the choices of Feature Manager on the left screen sides. On the image above we can see that the several gear parameter choices should be fill, and for this section, we will make a Spur gear that having a parameter like this:.
Here we go, our gear would be like this. Those are How to create Spur Gear with SolidWorks and if you want to modify the gear back, it means giving tapped hole to the keyway, just modify itself with your own design. Just see the next tutorial. If you want to design spur gear or other gear easily you can design with toolbox menu, just fill the parameters of gear.

Necessary Always Enabled.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.Gear mates force two components to rotate relative to one another about selected axes.
Valid selections for the axis of rotation for gear mates include cylindrical and conical faces, axes, and linear edges.

Does SolidWorks Have a Gear Tool
Gear Mates Gear mates force two components to rotate relative to one another about selected axes. Also: You can mate any two components that you want to rotate relative to one another. You do not have to mate two gears. Similar to other mate types, gear mates do not prevent interference or collisions between components. To prevent interference, use Collision Detection or Interference Detection. To revert to the default value, delete the override value.
The background color of the box is white for the default value, and yellow for the override value. Parent topic Mechanical Mates.
