Support base used for processing slewing bearing

Abstract: The utility model relates to a support base used for processing a slewing bearing The support base comprises a panel and four side plates welded on the periphery of the panel, wherein the edges of the adjacent side plates are fixedly connected, the support base is characterized in that an included angle between each side plate and the panel is 105 degrees, the support base is also provided with a stiffening beam, and the stiffening beam is tipsily arranged in a cavity formed by the panel and the side plates; and one of the side plates is also provided with a handle The support base provided by the utility model has the advantages of reasonable structure, low manufacturing cost, good weight capacity, light self weight, and is convenient and practical

Composite board automatic gluing and laminating production line

Abstract: The invention discloses a composite board automatic gluing and laminating production line. The composite board automatic gluing and laminating production line comprises a machine frame, a pushing cylinder, a lower bearing plate, a pushing head, a support, a plate case, a plate bearing strip, a pre-pressing mechanism, a glue box, a peristaltic pump, a coating mechanism, a material taking mechanism,a jacking cylinder, a plate bearing mechanism, a vertical column, a heating mechanism, a servo motor, a gear, a slewing bearing, a round disc heating box, a bearing seat, a supporting rod, a stoppingplate, a material collecting mechanism, a vertical frame, a lower pressing cylinder, an upper die, a connection arm and a synchronous lower die mechanism. The device is simple in structure, can coatthe glue onto the surface of a base plate uniformly, the situation that the glue is not well attached due to secondary pollution can be avoided, the gluing area is accurate, the glue can be recycled,and thus glue waste is effectively avoided. Meanwhile, through floating type design, the upper die and the lower die are laminated simultaneously, uniformity of the lamination is effectively improved,the upper die and the lower die are driven by the single pressing cylinder to laminate, laminating synchronicity is effectively ensured, and the production line can meet the lamination requirement ofbase plates with different layers.

Slewing bearing service life prediction method

Abstract: The invention relates to a slewing bearing service life prediction method. The method is characterized by comprising steps that temperature, torque and original vibration signals of a slewing bearing are extracted; dimensional and non-dimensional characteristics values of the signals are selected in a time domain, and a sensitivity characteristic value corresponding to each signal is selected; principal component analysis (PCA) dimension reduction processing for the sensitivity characteristic value of each signal is carried out, and a temperature PCA performance degradation index, a torque PCA performance degradation index and a vibration PCA performance degradation index of the slewing bearing are respectively formed; service life period state distribution of the slewing bearing is acquired through a self-organizing characteristic mapping neural network (SOM), and input sample class division is accomplished. According to the method, degradation characteristic index establishment and service life period state distribution of the slewing bearing can be realized, residual service life is effectively predicted, and huge loss caused by abrupt ending of service life of the slewing bearing can be substantially reduced.

Slewing bearing wearing extent on-line measurement and lubricating grease automatic filling-up method

Abstract: The invention relates to a slewing bearing wearing extent on-line measurement and lubricating grease automatic filling-up method. The method comprises the steps of utilizing the change of a lubricating grease insulating property to judge the change of metal particle content in a lubricating grease, and judging the wear condition of a slewing bearing raceway, so as to indirectly judge the generation and development of the damage of the raceway and be used for optimizing a lubrication condition of a slewing bearing, determining filling-up quantity and filling-up frequency of the lubricating grease according to the wear condition, and realizing the required lubrication of a self-adapting working condition. The method provided by the invention avoids the problem of separation of a wearing extent value of a micrometric displacement measuring method, the problem of self abrasion of a contact-type micrometric displacement transducer, and the problem of insufficient non-contact type micrometric displacement range and poor accuracy, can realize on-line measurement, avoids the problems that the regular fixed point filling-up has the problems of excessive pouring grease or shortage and the like, optimizes the lubrication condition of the slewing bearing, effectively improves the load-carrying capability of the slewing bearing, prolongs the service life, and fills up an industry blank; and the purposes can be realized just by general instrument and equipment such as electric control grease pouring pumps, insulation meters and measuring heads.
