MODELING AND SIMULATION OF CYCLOID CURVES WITH APPLICATION IN ROBOTICS

Mechanical power transmission by reducing the rotating speed under a constant transmission ratio represents the function of a large group of products known as speed reducers. Cycloid gearing roller (invented by L. Braren), through its qualities, has an important role in modern mechanical transmissions. The difference between numbers of teeth of the cycloid gear roller can be equal to 1 (| Z1 - Z2 |  1), without risk of interference, as a result, can be obtained big gear ratios in accordance with in lower overall dimensions.Thus, this paper presents the modeling and simulation of cycloid curves (epicycloids, respectively hypocycloid), which generates the cycloid gears used a lot in robotics.
