representation of a non-uniform reciprocating motion

Description:

• The Whitworth mechanism is also known as the quick-return mechanism.
• It represents a revolving crank slider and produces non-uniform stroke movement with slow forward movement and fast backward movement.
• This mechanism is used in tools, packaging and transport machinery.
• The KI 140unit generates non-uniform stroke movement by means of a Whitworth mechanism.
• The experimental unit comprises the drive disk with crank and coupling, the driving rod and the cylinder.
• The angle is adjusted using the crank disk, and an angle scale is integrated into the base plate.
• A millimetre-precise steel ruler is attached to the cylinder to measure the stroke.
• The elements are mounted on a base plate.
• Two handles make it easy to carry and stack the unit.
