Selection of a Belt Drive

Following are the various important factors upon which the selection of a belt drive depends: 1. Speed of the driving and driven shafts, 2. Speed reduction ratio, 3. Power to be transmitted, 4. Centre…

Acceleration in mechanisms

We have discussed in the previous topics the velocities of various points in the mechanisms. Now we shall discuss the acceleration of points in the mechanisms. The acceleration analysis plays…

Rubbing Velocity at a Pin Joint

The links in a mechanism are mostly connected by means of pin joints. The rubbing velocity is defined as the algebraic sum between the angular velocities of the two links which…

Velocity and Acceleration Analysis of Mechanisms

In this, we shall discuss the relative velocity method for determining the velocity of different points in the mechanism. The study of velocity analysis is very important for determining the…

Quick return motion mechanisms

Quick return mechanisms are used in machine tools such as shapers and power driven saws for the purpose of giving the reciprocating cutting tool a slow cutting stroke and a…

Inversions of Single Slider Chain

Slider crank chain: This is a kinematic chain having four links. It has one sliding pairand three turning pairs. Link 2 has rotary motion and is called crank. Link 3 has…

Coupler Curves

The link connecting the driving crank with the follower crank in a four bar linkage is called the coupler. Similarly, in the case of a single slider crank mechanism the…

Inversion of Mechanism

A mechanism is one in which one of the links of a kinematic chain is fixed. Different mechanisms can be obtained by fixing different links of the same kinematic chain.…

Mechanism

When one of the links of a kinematic chain is fixed, the chain is known as mechanism. A mechanism with four links is known as simple mechanism, and the mechanism with more…

Kinematic pair

The two links or elements of a machine, when in contact with each other, are said to form a pair. If the relative motion between them is completely or successfully…
