EXPERIMENT PREPARATION FOR LASER-CUT SPUR GEARS EFFICIENCY TESTING

Cylindrical spur gears remain widely used in mechanical systems due to their simplicity and effectiveness, despite being a long-established component in engineering. While many aspects of spur gear design, analysis, and application have been thoroughly studied during decades, recent research trends have shifted toward optimizing manufacturing efficiency and reducing production costs. This paper presents the preparation of laser-cut spur gears for the purpose of evaluating their power transmission efficiency. The gears were produced using laser cutting technology, which offers potential advantages in terms of production speed and cost-effectiveness compared to conventional manufacturing methods. The experimental evaluation is planned to be conducted using the GUNT AT200 test rig, where the gears will be mounted on test gearboxes. Multiple gear pairs with identical center distances will be examined under controlled conditions to assess their mechanical efficiency. The primary objective is to determine whether laser-cut gears, despite potential limitations in precision and surface finish, can achieve acceptable performance for practical applications, particularly in prototyping and low-load scenarios.
