Infinitely variable transmission (IVT) is a system that gives a continuous (non-discrete) variation that includes zero in transmission ratios between two rotating elements. In this paper, a cam based IVT mechanism was designed and simulated using SolidWorks software containing two identical units. Each unit included a cam with a follower and oscillatory slotted links pivoted at a hinge that could be moved vertically by altering the transmission ratio, achieved by using a hydraulic ram or a power screw. system units also include a grooved wheel and a follower or actuator. During operation, the grooved wheels displayed an oscillating rotational motion, so that they are connected to the output shaft via one-way clutches (ratchets) to give the output shafts one-way directional motion. The cam profiles are designed and investigated within the system with regards to performance. A combination of uniform velocity and 1-5 polynomial profiles where selected and designed for the current study In general, the results obtained from the simulation showed compatibility with the expected theoretical results derived from the design of the current IVT system. These results indicated uniform velocity during the power stroke in each unit for all parts in the units. However, the ratchets used in this study produced a noticeable fluctuation in the angular velocity of the output shaft, and further work on the selection and development of more efficient ratchets is thus strongly recommended.

Infinitely variable transmission (IVT) is a system which delivers the ratio between two turning elements to a continuous (non-discrete) variation (including zero). This article uses Solidworks software to build and simulate a cam-based IVT system. There are two identical units in the system under examination. Each unit comprises a cam with an oscillating slot connection that swings on a hinge and can be vertically shifted by changing the transmission rate. This modifier can be a power screw or a hydraulic ram. In addition, a grooved wheel and followers or an actuator are included in the system units. The raised wheels swing rotating movement, such that they are coupled by a single-way clutch to the output shaft (ratchet) to move the output shaft one way. During the performance research, cam shapes are considered and examined inside the mechanism. a mixture of the unchanging speed and 1-5 polynomial shapes, used for the current investigation and tailored for The results produced from the simulation generally reveal the theoretical results expected in accordance with the layout of the current IVT system. For all parts in these units, the findings imply a uniform velocity while each unit is powered. In this investigation, nevertheless, the ratchets used cause remarkable fluctuations in the angular speed of the output axis. Further research is therefore urgently needed in the choice and investigation of more efficient ratchets.
