Descrição Geral

The Whitworth Quick Return Mechanism, "MBM2", is a mechanism able to transform circular movement into reciprocating movement. It ismade of aluminum and consists of a rotary element, called crank, with a graduated disk, connected to a rigid bar, called connecting rod.

When rotating the crank, the connecting rod moves back and forward. The rotation motion of a crank or crankshaft causes a rectilinear reciprocating motion of a piston or plunger.

The forward reciprocating motion is at a different rate than the backward stroke.

EXERCÍCIOS E PRÁTICAS GUIADAS

EXERCÍCIOS PRÁTICOS GUIADOS INCLUÍDOS NO MANUAL

  1. To demonstrate the action of a simple Whitworth quickreturn mechanism.
  2. Graphic determination of the relationship between the linear displacement of the connecting rod and the angular displacement of the input crank.
  3. More exercises and practices may include the determination of the velocity and acceleration of the connecting rod by graphical differentiation and comparison with the values obtained by velocity and acceleration diagrams.
