Abstract:

In vehicles and some machines, clutch systems are used between motor and transmission as torque and motion drivetrain. Clutch systems consist of 3 main components and 2 auxiliary components as clutch disc, clutch cover assembly, and clutch bearing. In our study, the “outer main plate” part of the sub-parts of the clutch disc, which is one of the main components of the clutch, is discussed. The clutch disc is exposed to rotation momentum and pressure force during the transmission of motion. In the production of the outer main plate within the Dönmez Clutch Inc. drilling-cutting, straightening, and turning operations are applied. In this study, in the design of the outer main plate, the indentations with the depth of 0,05-0,04 has been applied on the surface. In our study, the effect of the indentation on the surface of the outer main plate to the stress around the rivet holes and on the main plate surface has been examined. Two different main plate designs with and without the indentations have been simulated by defining the real working conditions on the static structural module of the ANSYS commercial software. Through the two designs, equivalent stress, principal stress, total deformation, and stress vectors have been obtained. As a result, the indentation operation has been observed to absorb the stress on the outer main plate and around the rivets by distributing the stress on the surface of the part.
