Inversion of Double Slider-Crank Chain: Scotch Yoke
The double slider-crank chain is a mechanism commonly used in various engineering applications, such as engines, compressors, and pumps. It consists of two sliding pairs and two turning pairs. The input and output links in this chain are typically rotating and sliding in nature.
Scotch yoke is an inversion of the double slider-crank chain. It is a mechanism that converts rotary motion into reciprocating motion or vice versa. In this mechanism, the input link is a rotating crank, and the output link is a sliding yoke or slider. The sliding yoke moves back and forth in a straight line.
Explanation:
1. Double Slider-Crank Chain:
- Input link: Crank
- Output link: Slider
- Motion: Rotary input motion is converted into reciprocating sliding motion of the slider.
2. Scotch Yoke:
- Input link: Crank
- Output link: Slider (Yoke)
- Motion: Rotary input motion is converted into reciprocating sliding motion of the yoke.
The scotch yoke mechanism is used in various applications where a linear reciprocating motion is required, such as in reciprocating compressors, reciprocating pumps, and some engines. It provides a simple and compact design for converting rotary motion to linear motion.
The scotch yoke mechanism consists of a circular disc or crank connected to a rotating shaft. A connecting rod is attached to the disc, and the other end of the rod is connected to a sliding yoke. As the crank rotates, the yoke moves back and forth in a straight line.
The advantage of the scotch yoke mechanism is its simplicity and high efficiency in converting rotary motion to linear motion. It eliminates the need for complex linkages and provides a compact design. However, it has limited applications compared to the double slider-crank chain.
Overall, the scotch yoke mechanism is an inversion of the double slider-crank chain and is commonly used in applications where linear reciprocating motion is required.
