Week 10- Assembly Workbench

AIM:           

      To create 2 assemblies according to the content covered in the course videos. You will be provided with 2D diagrams of the components and you will have to first create the individual part files and then create a complete assembly of those part files in the assembly workbench. After creating the assembly make use of the drafting tools to create a 2D drawing similar to the one given in the assignment folder.

 QUICK CRANK MECHANISM-

• A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of link with three turning pairs and a sliding pair. A quick return mechanism is a subclass of a slider crank linkage, with an offset crank.
• Quick return is a common feature of tools in which the action is performed in only one direction of the stroke, such as shapers and powered saws because it allows less time to be spent on returning tool to its initial position.

CV-JOINT:

• Constant velocity joints (also known as homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly used in front wheel drive vehicles. Modern rear wheel drive cars with independent rear suspension typically use CV joints at the ends of the rear axle half shafts and increasingly use them on the drive shaft.
• Now i will create each part shown in the above CV joint. I'll use the Boolean method features to create all the parts.
