WQ-JXZZLX epicyclic efficiency test bench of the test bed is testing integrated cash analysis laboratory equipment sensors, computer monitoring and control technology, for understanding a given gear train, epicyclic (planetary gear train and differential gear train ) and structural composite gear train; the determination and efficiency ratios three wheel system. The bench is suitable for mechanical and electrical professional open wheel system structural analysis and efficiency testing laboratories, it is one of the important principles of laboratory equipment and machinery. Main technical characteristics: 1. The experiment station by different braking device is a brake and a relaxed state, to achieve fixed axis gear train, the conversion planetary gear train, the differential gear train, so that students build perceptions of the structure of the various gear train. 2. Determination of gear ratio and transmission efficiency of three wheel train mechanism, and then analyze their sports performance. 3. Bench shape for the table plate + box floor structure, easy adjustment arrangement laboratory. Bench structure cleverly designed, easy to quickly switch between the pilot project, greatly reducing the experimental preparation time. 4. Bench by SCM system, the rotational speed and torque of each sensor to collect data, connected to the computer via RS232, processing and analysis, it may clear and intuitive display various data and experimental curves in the software interface window. 5. Equipped with special test software, which is equipped with experimental institutions animation, experimental guidance documents to help with drawing, save function and print test curve and test reports, test interface, easy to operate, suitable for students to use in the open laboratory. Pilot projects: 1. Learn fixed gear train, epicyclic (planetary gear train and the differential gear train) and in line with the structure of the train wheels; 2. Determination of fixed axis, planetary gear train, the gear ratio of the differential gear train; 3. Determination of fixed shaft, drive efficiency planetary gear train.
