WebThe Scotch yoke is a mechanism for 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. ...

WebThe Scotch yoke is a mechanism for 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. The shape of the motion of the piston is a pure sine wave over time given a constant rotational speed. Web31 May 2024 · Fig. 5 Our Scotch Yoke unit design. 1. Motor For our application, we decided to drive the crank/rotating wheel using a micro servo motor. Micro servo motor SG-90 has a torque of approx 1.8 kgf.cm. 2. Materials used To keep the weight of the movable part as low as possible, we decided to fabricate movable parts using light weight materials. If we …
Web3 Sep 2024 · Weight Imbalance – The center of gravity is offset from the shaft axis and it continuously relocates as the actuator operates. Force Imbalance & High Friction Losses – 100% of the piston and spring forces act upon the output shaft and the bushings that support the shaft. The shaft/bushing friction leads to wear and reduced output torque. WebII. MODIFIED SCOTCH-YOKE MECHANISM: The Scotch–Yoke mechanism in the proposed design is driven by a pair of non-circular gears 1 and 2 and two circular gears 3 and 4 (Fig. 2.1(a)) so that the input to the conventional scotch-yoke mechanism is no longer a constant i.e., ≠ constant (Fig 2.1(b)). Fig 9.2.1: Composition of gear drive with ...
WebScotch Yoke. The Scotch Yoke mechanism converts rotary to linear motion. As the disc/pin rotates, the shaft/oblong moves left and right in a sinusoidal motion. The advantages of …
