Greatest Mechanical Principles and Inventions

Here are some of the animations of the greatest mechanical principles and inventions, which shows greatness of human brain. Simple animation pictures are used to explain mechanisms of Boxer Engine, Geneva Drive, Radial Engine, Wankel Cycle.

1. Boxer Engine:

A Boxer Engine is a flat engine IC engine with multiple pistons that move in a horizontal plane. The layout shown in animation has cylinders arranged in either side of a single crankshaft and it is sometimes known as horizontally opposed engine.

2. Geneva Drive:

Geneva drive mechanism animationThe Geneva drive is a gear mechanism that translates a continuous rotation into an intermittent rotatory motion. The rotating drive wheel has a pin that reaches into a slot of the driven wheel in regular intervals advancing driven wheel by one step. The drive wheel has a raised circular blocking disc that locks the driven the driven wheel in position between steps.

3. Radial Engine:

Radial Engine is a reciprocating type IC engine configuration in which the cylinders moves outward and then inwards in regular intervals from a central crankshaft. It looks like a stylised star when viewed from the front. The radial engine configuration was very common used in aircraft engines before turbine engines became in use.

4. Wankel Cycle:

The Wankel engine is a type of IC engine using an eccentric point rotatory design to convert pressure into rotatory motion. Use of Wankel engine delivers advantages they are simplicity, smoothness, compactness, high RPM and a high power to weight ratio. Wankel Cycle engine is commonly referred to as a rotatory engine.
