Abstract

Belt transmissions are often used in industry machinery to transmit power. Another field of application concerns the Front End Accessory Drive of Automotive engine; it recently asks for better performances in order to allow development of new technological innovations as starter-alternator integration in transmission. Belt slip on pulley causes the transmission error. This can be controlled to some extent using appropriate initial tension. The flat belt pulley surface is plain. In the present study, the effect of positive geometry square and round shape dimpled surface instead of plain is investigated. The remaining parameters except the contact surface of belt and pulley are same. The experimental set up developed is used to determine the belt slip and slip torque for varying load and speed conditions. Two different dimple geometries are considered for this investigation. The paper elaborates the application of aluminum material liners on the flat pulley in order to improve performance. This is relatively new method. Results as to percentage slip versus load and percentage slip versus torque is plotted. For Geometrical profile design of square & round shape positive geometry flat belt pulley we use 2-d cad, for 3-d modeling we use Unigraphix N-x & for analysis we are using Ansys work bench 14.5, to obtain comparative analysis of plain, square dimpled & round dimpled pulley ANOVA is used.
