Development of the Process of Manufacturing CVT Pulley
The aim of the study is to improve the traction and dynamic characteristics of the car, as well as the development of the manufacturing process of one of the critical parts of the proposed design. The objectives are as follows: - to reduce the size of the CVT; - to increase the gear ratio of the CVT. The problem can be solved by upgrading the driven pulley to increase the range of transmission ratios. Modernization of the V-belt transmission is to create a two-section driven pulley, with automatic locking of the outer section relative to the inner one, and increase the diameter of the driven pulley compared to analogues. The technological process of manufacturing a modernized CVT pulley is proposed; the analysis of technological effectiveness of the proposed design of a pulley is made; technical requirements to the CVT pulley are given; the prototype was built; the production scheme was developed. A tool for grinding operation was developed; the installation scheme was designed.
