Solidworks has inbuilt design tools it can speedup the design and generation of particular parts like cams, beams and bearings. Solidworks allows designers to produce both are linear and circular cams wih ease.
Cams in Solidworks can be created in three simple ways:
- One can choose to create cams from scratch by using modelling tools such as extrusion.
- Secondly you can choose to import curves that define the cam profile from an existing library.
- Thirdly one can decide to use the Solidworks toolbox cam feature that lets you define the cam specifications and in turn generates the 3D model based on these specifications.
For this demonstration I will use the inbuilt Cam tool inside Solidworks. To do this therefore we are required to first enable the Solidworks toolbox add-in inside the add-ins folder.
After doing this you can proceed to the Solidworks add-in tab and click on cams.
The above window shows three tabs which models the Cam. The first tab defines the units for the cam. Also you have to choose from either a linear or circular cam. You can then choose the follower type, the size of follower radius and the starting angle.
The motion tab lets you define the type of profile the cam will have.
If you are creating a circular am you need to define the motion over 360 degrees.
In the creation tab you are required to define various parameters such as the hub diameter, thickness and specifications for the through hole.
You can choose to make your cam internal or external.
Once you have defined the specifications you can then proceed to create the Cam.
Note that all the cam surfaces need to be tangent to each other in order for the cam mate in the assembly to work. Filleting the edges makes these surfaces tangent to each other.
