Inversions of Mechanisms

Submitted By – Chetan Jaganure, Vishal Kamble.

Guide name – Mr. Sushant Patil sir.

Inversion is the method of obtaining different mechanism from single kinematic chain by fixing different links in turn.

Types of mechanisms :a) Four bar chain mechanism – this mechanism consist of all four turning pair. 1) coupled wheel of locomotive, 2) beam engine.

b) Single slider crank chain mechanism – this mechanism consist of three turning pair and one sliding pair. 1) rotary IC engine, 2) with worth quick return mechanism, 3) crank and slotted lever mechanism.

c)Double slider mechanism – this mechanism consist of two turning pair and two sliding pair.

1)scotch yoke mechanism , 2) Oldham’s coupling.

Four bar chain mechanism1) Coupled wheel of locomotive

Purpose is to transmit the rotary motion of one wheel to another.

2) Beam engine mechanism

• Purpose is to convert rotary motion to reciprocating motion.• Application is to drain water or oil from mines.

Single slider crank chain mechanisms

1) Rotary IC engine

2) With worth quick return mechanism

3) Crank and slotted lever mechanism

Application : It is used in in shaper machine

Double slider crank chain mechanism

1)scotch yoke mechanism

2) Oldham’s coupling.
