Sliding bearing bush with embedded quality ultrasonic C scan system parts drive mechanism design

Abstract: To achieve intelligent ultrasonic detection of a kind of effective way of ultrasonic water immersion detection technology, the to improve the speed and quality of the ultrasonic detection has important significance. In the development trend of today's society, the development of high speed, high precision ultrasonic immersion scanning system can very effectively improve the automation level of ultrasonic detection. It has a broad application prospect.

Is designed in this paper embedded bearing of sliding bearing with quality ultrasonic C scan system component, the driving mechanism, the driving mechanism of the design principle and structure, running process is described in detail, and the mapping of the various parts of the model and two-dimensional maps, and the whole assembly of two-dimensional map. The design first of ultrasonic C scanning technology development at home and abroad present situation, the principle and characteristics of simple overview, then the mechanical structure design of the mechanism and main components of the checking calculation. The mechanism mainly comprises a driving device, transmission device, rotary part, a water tank and a machine frame block. Finally the were summary and outlook.

Keywords：Water immersion test; ultrasonic C scan; driving mechanism;
