Lecture 15.3 Example of 3rd Inversion of Slider - Crank Mechanism : Oscillating Cylinder Engine Mechanism

3rd Inversion of Slider - Crank Mechanism : Oscillating Cylinder Engine Mechanism

Coupler link 3 is fixed OR

Fixed Link = Frame =Originally [link3 -Coupler]

Input link = Oscillating (Rocking) Cylinder = Originally [ link 4 - Slider]

Motion - Transfer Link = Piston with Piston Rod = Originally [ link 1 - frame ]

Output Link = Driven Crank = Originally [link 2 - Crank]

Note: Oscillating Cylinder Mechanism is used for example in a bicycle foot operated air pump. Here Motion - Transfer Link OR Coupler Link  ( Piston attached to piston rod) is given an input motion (oscillatory motion). This input link [ piston ] slides / reciprocates within Oscillating (rocking) cylinder [ 4th link] that has the same angular velocity as piston [ link - 1].

Construction Line, Line Type , Line Type Scale

Function of CAD Software  Drawing of objects using various elements (1) CONSTRUCTION LINE Construction line creates a line of infinite length At the command prompt, enter XLINE Command : XLINE and press enter Specify a point or [Hor/Ver/Ang/Bisect/Offset : hor [ Type 'hor' for horizontal line] Specify through point : [Select a point on screen] Specify through point : [Select another point] The CONSTRUCTION LINE passes through the entire drawing area. Use: Projecting points from FRONT VIEW to TOP VIEW or SIDE VIEW (2) One can type LINETYPE at the command prompt to invoke the line type manager dialogue box. Select required LINETYPE and click OK (3)One can type LTSCALE at command prompt to change the LINETYPE scale. At the command prompt, enter LTSCALE Command : LTSCALE New scale factor <current >: Enter a positive real value or press enter
