Mechanisms consist of rigid bodies connected by joints to create desired motions or force transmissions, playing a crucial role in machines. Various types of joints and mechanisms serve different functions, such as motion generation and force transmission. Special-purpose mechanisms like the quick return mechanism and universal joint demonstrate their applications in machinery and automotive systems.
A mechanism is a collection of rigid bodies connected by joints for motion or force transmission.
Mechanisms can be classified based on their function, constraints, or type of joint.
Common mechanisms include four-bar and slider-crank mechanisms, each with several inversions for different applications.
A combination of rigid bodies (links) connected by joints to create desired motions or facilitate force transmission.
Includes lower pairs (e.g., revolute, prismatic joints) and higher pairs (e.g., cam and follower) based on the nature of their contact.
The simplest closed-chain mechanism that converts rotary motion into oscillatory or reciprocating motion.
Mechanisms used in shaping and slotting machines that allows a faster return stroke than the cutting stroke.
A joint that allows the transmission of torque between shafts at varying angles, commonly found in automotive drive shafts.
