Working Principle (Elbow Mechanism) Components: It uses an input shaft, an output shaft, and several (e.g., 3-8) identical, bent cylindrical linkages (pins) connecting hubs. Input Rotation: The input shaft rotates, causing its hub to turn. Linkage Action: The input hub pushes the bent links, which slide within holes in a stationary housing or another hub. Power Transfer: This sliding motion translates into a rocking or reciprocating movement of the links. Output Rotation: The links then push the output hub, causing it to rotate and transfer power to the driven shaft, even if it's at a 90° angle to the input. Advantages Simplicity & Cost: Fewer complex parts, making them cheaper to manufacture. Compactness: Ideal for tight spaces where gears would be bulky. Angle Versatility: Can transmit power at various fixed angles (0-180°). Limitations Low Torque: Not suited for high-torque, high-speed applications. Fixed Ratios: Generally have fixed speed/torque ratios, unlike geared systems. Applications Tower clocks (e.g., historic London clock) Drilling machines (for angular drilling) Lubrication pumps (CNC lathes) Periscope movement (submarines) #automobile #mechanism #gear #3danimation #technical #mechanicalengineering #animation #gearless #mechanics
