| With the development of industrial technology, the reliability of the bearing increasing demands. Cleanliness of bearing and bearing internal defects has a great impact on the reliability of the bearing. If the bearing containing dirt,that has a great impact on the life of the bearing. Currently there is no uniform bearing cleaning technology. Spray cleaning technology is the most widely used bearing cleaning technology, but, It often requires retooling, and because the presence of an uneven surface raceways, spray cleaning has some limitations. It is necessary to find a good cleaning effect, high degree of automation, no tooling bearing cleaning methods. On the other side,if there is a slight intensive holes, cracks and other defects in the bearing rings, bearings will produce vibration and noise, that is never permissible. Currently, most bearing manufacturers use artificial as the bearing ring detection method, Because bearings are mass-produced mechanical basic components, this method does not meet the requirements of productivity. Therefore, it needs to be an on-line automatic inspection equipment.Based on domestic and foreign technology and the customer’s needs, We designed the bearing ring cleaning and online automatic testing equipment. The device can be applied to the outer diameter of 260-460mm, height bearings in the size range of 42-180mm. This equipment can be divided into auxiliary function modules with the main function module in two parts. Auxiliary function modules include transport mechanism, limit mechanism and displacement mechanism, the main function modules include cleaning station and an ultrasonic flaw detection station.Based on the principle of a slider-crank mechanism, We designed a locating and clamping mechanism, Such agencies do not have tooling. Positioning accuracy and clamping force meet the requirements. With a brush for cleaning bearings, bearing cleanliness meet customer requirements. Ultrasonic flaw detection scanning mechanism enables to adjust the angle and distance of the probe. Duplicate detection cover of probe more than 10%. Using ANSYS to analyze the rigid frame, chassis rigidity to meet the requirements.According to the bearing cleaning and bearing testing features, We developed a bearing automated production equipment, this device has a simple structure, powerful features, a high degree of automation. Besides, this equipment has no tooling and no adjustment. I wish this equipment is help to improve the bearing cleaning and automatic detection... |
