SIX BAR LINKAGE MECHANISM

By | May 31, 2018

ABSTRACT:

A six-bar linkage is a one level of-flexibility system that is developed from six connections and seven joints. A case is the Klann linkage used to drive the legs of a mobile machine.

As a rule, each joint of a linkage associates two connections, and a double connection bolsters two joints. In the event that we view a hexagon as built from six paired connections with six of the seven joints framing its vertices, at that point, the seventh joint can be added to interface two sides of the hexagon to shaping a six-bar linkage with two ternary joints. This sort of six-bar linkage is said to have the Watt topology.

PRESENTATION:

A six-bar linkage can likewise be developed by first amassing five twofold connections into a pentagon, which utilizes five of the seven joints, and afterward finishing the linkage by including a paired connection that interfaces two sides of the Pentagon. This again makes two ternary connections that are currently isolated by at least one parallel connections. This sort of six-bar linkage is said to have the Stephenson topology.

ADVANTAGES:

• Six bar linkage straightforwardly apply to any broad instrument.

• As indicated in the first specify of the rigging train, the torque proportion is a component of the speed or precise speed proportion amongst yield and information connections of the system.

• The torque proportion is a component of geometric parameters, which, on account of a linkage, will by and large change over the span of the instrument movement.

DISADVANTAGE:

• Moderate speed application as it were

APPLICATIONS:

• Some wiper engine applications
