What is Scotch yoke?
The Scotch Yoke (also known as slotted link mechanism) is a reciprocating motion mechanism, converting the linear motion of a slider into rotational motion, or vice versa. The piston or other reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part.
What is a Scotch yoke used for?
The Scotch yoke mechanism is most commonly used in control valve actuators in high-pressure oil and gas pipelines, as well as in various internal combustion engines, such as the Bourke engine, SyTech engine and many hot air engines and steam engines. This mechanism does not create lateral forces on the piston.
Who invented the Scotch yoke?
The Scotch yoke was used as an energy conversion device for the Bourke engine, a two-stroke engine developed early in the 20th century by engineer and inventor Russell Bourke.
How the Scotch yoke converts motion?
In the Scotch yoke mechanism, the rotary motions of the crank are converted to the linear motion of the alternating part. Power is supplied from the DC motor shafts, & the crank attached to the shaft rotates. In this way, the rotational speed of the crank is converted to the reciprocating motion of the yolk.
What is Scotch Yoke actuator?
A scotch yoke actuator may be defined as a mechanical device that converts linear force into torque to motorise quarter-turn valves. A single-acting scotch yoke actuator is made of three main components: housing containing the yoke mechanism, pressure cylinder containing the piston and spring enclosure.
What is DOF of scotch yoke mechanism?
Degree of freedom (DOF): Two DOF mechanisms such as: rotation such slotted sphere, two translation motion, one rotation + one translation independently such cam.
How many revolute joints does a scotch yoke mechanism have?
two revolute joints
The double slider-crank linkage has four links joined in a kinematic chain and consists of two revolute joints and two sliding or prismatic joints.
Are cranks zombies?
In the film series, Cranks are depicted as zombie-like creatures with strange vine-like growths protruding from their bodies. The book series clearly defines differences between Cranks and regular zombies, however, as Cranks remain alive and somewhat can speak.
What is difference between slider crank and scotch yoke mechanism?
A scotch yoke mechanism is one which translates rotary to linear movement or vice versa, by using a pin moving in a slot. A slider crank is a mechanism is one which translates linear to rotary movement using an oscillating link or con-rod.
What is quaternary link?
A quaternary link contains four kinematic links. With the four links, we can form four binary links as shown in the picture attached. But the theory say only three.
