Abstract. This paper presents the derivation of a simplified mathematical equation to predict the output speed of an overrunning clutch. The working principle of the overrunning clutch was studied and mathematical equations were derived for different cases. A MATLAB Simulink model was created to simulate the equations and ADAMS/View simulation was used for verification. The equations are able to calculate the output motion with minimal errors. The equation can be used for a quick estimation to predict the output speed for any kind of input motions.

“…For a standard operation in a dry environment, the major components of the friction torque are the rolling and sliding friction. K. Liu et al had done a study on the effect of the sliding friction on the overrunning clutch with an oscillatory input motion [3]. The study shows that a well lubricated clutch will reduce the sliding friction.…”

“…Roller freewheel mechanisms are used the most widely in machines, which in some cases have the lack of reliability of work due to characteristic weaknesses: lack of durability and load capacity; large friction losses in the freewheeling period; high precision manufacture and installation of mechanism elements; considerable sensitivity to element deterioration [9][10][11][12][13][14][15][16].…”

The article contains a research of the influence of design parameters (material, the jamming angle) on operation reliability of eccentric friction-type freewheel mechanisms using calculated and experimental techniques. As the investigated factor, the lower limit of the confidence interval for the time between failures is adopted It is shown that the necessary reliability of the eccentric freewheel mechanisms is ensured when jamming angles are 8–10° and when their elements are made of material 100Cr6. The reliability of such mechanisms is 1.7 times higher than of roller free-wheel mechanisms. The results of the research can be used when predicting the reliability of the mechanisms in the drives of machines.

“…This allows to preserve mechanical parts from shocking each other, increasing the lifespan of the engine and improving the driver's comfort. Conventional clutches include electromagnetic clutches [2,3], gear clutches [4,5], friction clutches [1], overrunning clutches [6,7] and centrifugal clutches [8]. Car manufacturers requirements for greater power transmission, lightweight, low cost design, smaller design space, high comfort and high effectiveness lead to develop new clutches mechanisms such as ultrasonic clutch [9] or piezoelectric clutch [10].…”
