The Input torque balancing through addition of an auxiliary mechanism is a well-known way to improve the dynamic behavior of mechanisms. One of the more efficient methods used to solve this problem is creating a cam-spring mechanism. However, the use of a cam mechanism is not always possible or desirable because of the wear effect due to the contact stresses and high friction between the roller and the cam. 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. Therefore, the main advantages include reducing friction, vibration and piston wear, as well as smaller engine dimensions. However, the input torque of the Scotch yoke mechanism is variable and can be balanced. This work proposes to balance the input torque of Scotch yoke mechanisms without any auxiliary linkage just by adding linear springs to the output slider. After cancellation of inertial effects the input torque due to friction in joints becomes constant, which facilitates the control of the mechanism. An optimal control is considered to improve the operation of balanced Scotch yoke mechanisms.

It is a simple mechanism, the rotary motion of pin convert into linear motion. First, the power supply to be connected in DC motor, when the shaft to start in rotation moment, now the crank rotates the pin slider inside of yoke part and also move in forward direction. When the Crank will be rotate in clockwise direction and yoke will be getting displacement movement at forward. The maximum displacement of yoke depends upon the length of Crank. The crank is rotated along clockwise revolution at the same time the Yoke sliding completely moved in forward direction. It will take more time to start return stroke. After some time, the crank will be rotated continuously to come back in initial position of rotation. So, the Yoke move in backward direction and come back for initial position. Therefore, the crank has full revolution to be completed, At the same time the Yoke will complete the forward and backward movement of Sliding. By means of the full revolution of Crank, the Yoke will be sliding through equal of double length of Crank. The Yoke displacement can be controlled by varying of crank length.The Scotch yoke is also known as slotted link mechanism. The slotted link mechanism is used for converting the linear motion of a slider into rotational motion or vice-versa.
