Engineering Plastics bearing VS metal composite bearings

At present the use of the bearings can be divided into general and the Rolling sliding bearing; rolling bearings and sliding bearing the name of principle can be adopted to distinguish, when the Rolling friction is rolling friction, and sliding bearing when the work is sliding; Rolling friction mainly depend on the size and manufacture of precision bearings and sliding friction bearings depends primarily on the size of the sliding surface material. Bearing in general face are all self-lubricating function in accordance with the sliding bearing materials into non-metallic sliding bearings and metal sliding bearing. At present, non-metallic sliding bearing mainly to plastic bearings, plastic bearings are generally used relatively good performance of engineering plastics made; comparison of professional engineering plastics manufacturers generally have the self-lubricating modification technology, through fiber, special lubricants, glass Beads of engineering plastics, etc. to enhance the self-lubricating modified so that it reached a certain performance, and then modified by plastic injection molding processed into self-lubricating plastic bearings, the world's comparison of professional manufacturers to Germany and China, the CSB IGUS公司. Metal Bearing is the most current three-tier composite bearings, bearings in general are such a carbon steel plate for the substrate, through sintering technology in the first sintering plate on a spherical copper powder and then a layer of copper powder layer on the sintering 0.03mm PTFE the lubricant of which the middle layer of spherical copper plate main role is to enhance the Deep Groove Ball Bearing Self-aligning Ball Bearing Angular Contact Ball Bearing integration between PTFE and strength, of course, the work also plays a certain bearing and lubrication; current global comparison of professional manufacturers to the U.S. The GGB company, Japan's OILES company and China's CSB companies can easily see through the above description, plastic and metal bearings sliding bearing exist following differences: 1, plastic bearings as a whole are lubricating materials, long life and the metal sliding bearing Lubrication is only the surface layer of 0.003 mm PTFE, when the thin layer of friction End also declared the end of life; 2, the use of plastic bearings will not rust and corrosion resistance phenomenon, and the rusting metal bearings can not be easy For the chemical solution, 3, plastic, metal bearings than the quality of light, more suitable for modern light-design trends, 4, plastic bearings manufacturing costs lower than metal, plastic bearings used in injection molding is more suitable for processing from the Volume production; 5, plastic bearings in operation without any noise, vibration absorption of certain functions because of plastic than metal bearings sliding bearing the existence of numerous advantages, the output of plastic bearings are growing, the use of plastic bearing occasions are also constantly The extension, from fitness equipment to office equipment and automotive industries, etc. are used plastic bearings, in the car on the highway without the use of plastic bearings. Plastic Bearing broad market prospects unlimited!

TV300 portable vibration meter main parameter

TV300 portable vibration meter main parameter measuring range acceleration: 0.1~392m/s (peak value) speed: 0.01~80cm/s (effective value) moves: 0.001~18.1mm (peak ~ peak value) allowance error: ±5% application temperature scope: 0~45℃ frequency range acceleration: 10Hz~200Hz 10Hz~ 500Hz 10Hz~1KHz 10Hz~10KHz speed: 10Hz~1KHz displacement: 10Hz~500Hz major function measurable quantity vibration acceleration, speed, displacement, natural frequency and rotational speed; Three display modes special-purpose: Simultaneously demonstrated that the acceleration peak value, the speed effective value and move the Feng Feng value; Popular type: Only the demonstration acceleration peak value (either speed effective value, or moves the Feng Feng value); Frequency spectrum: Demonstrated that the spectrograph instrument can draw up the real-time spectrograph; The instrument can act according to the hypothesis the warning line plan stick plot; Simple failure diagnosis: When is surpassed by the observed value the warning value, auto-alarm. With the printer connection, may print the survey value and the spectrograph; With the microcomputer connection, may analyze the survey value and the spectrograph (coordinate superior machine software); Formidable memory function: May save the 25X62 measurement result and 25 spectrograph back light liquid-crystal display; Power source: The lithium battery disposes the main engine + sensor + magnetism to attract the place basically to be possible to choose the TV300 superior machine software　　　1 set of printers　　　　　　　 1 magnetism attracts the place　　　　　　 1 probe module　　　　　　 1 long probe　　　　　　　 1

Rolling Term(4)

Rolling in: Rolling Road in the rolling ball or roller. Cage: wrapped in whole or in part, some rolling in, and together with the movement of bearing parts for the isolation of rolling, and often also guide the rolling body and will keep its bearings within. Isolated cases: in the adjacent and between the rolling movement together with the bearing parts for the rolling of isolation. Ball: ball rolling body. Roller: symmetry axis and the vertical axis in the line of a cross-section of the plane showed the round of rolling. Needle: the ratio of length and diameter of the larger small-diameter cylindrical roller, the general length of the diameter of between three to 10 times, but usually the diameter of not more than 5 mm. Needle head can have several forms. 3, Size Size programme include: Rolling Dimension system or form. Bearing series: a set of specific types of rolling bearings, with a gradual increase in size, in most cases, have the same contact angle between the size and shape have a certain relationship. Size Series: Series width or height and diameter series of series of combinations, the tapered roller bearing also includes the perspective series. Diameter Series: China's current standard-size part of the programme. Bearing diameter incremental series, each bearing a standard diameter, has a diameter series, and the diameter between the two often have a particular relationship. Width Series: China's current standard-size part of the programme. Bearing width of the incremental series, the diameter of each series of bearing diameter, the width of a series. High series: My current standard size of the thrust bearing part of the programme. Bearing a high degree of incremental series, the diameter of each series of bearing diameter, a series high. Series point: My current standard tapered roller bearing size part of the programme, the contact angle of a particular area. Dimensions: Bearing appearance of a limited size. Basic form factor for diameter, diameter, width (or height) and Chamfer dimensions. Bearing diameter: to the heart of the inner ring bearing diameter of the shaft or thrust bearing diameter circle. Bearing diameter: to the heart of the outer ring bearing diameter or thrust bearing the seat diameter. Bearing Width: limited to the heart of the two rings bearing the width between the end of the axial distance, the single tapered roller bearing is that the inner ring and the outer ring back of the back between the axial distance. Bearing Height: The height limit thrust bearing two washers between the back of the axial distance. - Diameter: tangent to the surface of the ball with two parallel distance between the plane. Roller diameter: the roller axis perpendicular to the plane of the line (radial plane), and roller tangent to the surface parallel to each other as the distance between the two tangent. Rated load calculation, the application of radial roller central plane. Roller length: contains roller end, the two radial distance between the plane.
