Slotted Link Apparatus Model MT 137

Sci-tech Slotted Link Mechanism Model MT 137 is an example of a quick-return mechanism, capable of transforming circular motion into reciprocating motion. It is made of aluminum and consists of a rotary element (graduated disk), called crank, 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. It is a reversible system through which the connecting rod can be displaced by turning the crank and the other way round. If the connecting rod generates the input motion (as a piston in a car engine does), the crank is forced to rotate.

Item Description

Features

  • ideal mathematical pendulum can be demonstrated
  • moment of inertia in an experiment on a rotary pendulum

Sci-tech Slotted Link Mechanism Model MT 137 is a quick-return mechanism. It is used in some modelling machines in which the cutting tool is slow in one way and fast in the return. This mechanism is a combination of an inversion of the slider-crank mechanism and a slider block. It is a mechanism capable of transforming circular motion into reciprocating motion.

Technical Specifications

Specifications

Bench-top unit.

Anodized aluminum frame and panels made of painted steel.

Main metallic elements made of stainless steel.

– Rotary element (crank) with a graduated disc and an indicator to read the angle.

 Experiment Possibilities

  • Demonstration of the action of a simple crank and slotted link mechanism.
  • Graphic determination of the relationship between the linear displacement of the sliding block and the angular displacement of the input crank. Other possible practices:
  • More advanced exercises may include the determination of the velocity and acceleration of the slider block by graphical differentiation and comparison with the valves obtained by velocity and acceleration diagrams.
