Functional Analysis and Mechatronic Design of a Cam Controlled Mechanism

The paper discusses a part of an industrial project which can be solved by mechatronic design method. In general, it follows VDI Guidelines 2206 and 2143, applying a model-based design tool. The objective of the project was to design and construct of a new state of the art pinion-engaging mechanism for starter motors. The pinion-engaging mechanism is a cam follower mechanism which contains the following parts: dc servo motor, rotational to translational transducer and the drive pinion. The rotational to translational transducer can be realized by designing a cylindrical roller follower mechanism. The goal of this paper is to present a mechanism design process and a test bench of the achieved construction. Some aspects of the kinematic relationships of the motion control, including electromechanical modeling are considered.
