Spindle in the use of the common problems and solutions

Spindle in use of the common problems and solutions - 2020 04 - 30 xin-wen zhang spindle is one of the main components of twisting winding on spinning frame, is long and thin axis of revolution as the main body two bearing assembly. On twisting machine, spinning frame, roving frame has a spindle. Used in spinning mill equipment scale and production capacity are expressed in terms of the number of spindle, the number and speed of spindle production capacity has a direct effect of corresponding working procedure, especially the spinning spindle. And the quality of the spindle and the quality of yarn, power consumption, environmental noise, such as labor productivity are closely related. Therefore, the performance of the spindle assembly of complete sets of spindle has a close relationship with and vibration. Spindle, then, what are the common problems in use process, and how to solve? Can cause of spindle spindle tip wear spindle tip wear hemp hand and vibration phenomenon Cheng Chao character. Spindle wear mainly appear in the spindle tip and bearing parts. Ingot pointed the normal wear and tear of smooth round sphere; Serious abrasive wear makes ingot pointed a gourd shape. Demonstrated the characteristics of the spindle tip wear is gourd head, the taper groove. Cause analysis when the bottom of the ingot and spindle tip part is out of the common axis, ingot rod move produces lateral contact sliding wear. If the bearing oil shortage, so bearing retainer wear speed will be faster. Normal wear of bearing retainer to lower accuracy, fit clearance increases, causing vibration. And where there is a certain load conditions, the spindle of wear depends on the spindle blade, the bottom of the ingot, bearing material, hardness, geometric accuracy and roughness, etc. In addition, the merits of the bobbin of the vibration of the spindle can influence is very big also, especially after high speed. Method the effect of spindle oil is not only the lubrication parts, and it is used to damping vibration free, and power consumption. For spindle on a regular basis and ensure the oil is enough, can delay the wear and tear of spindle pivot. Recommended product brand for the total loss system oil L ~ AN10 GB443 national standards, bearing lubricating oil ( Spindle oil) L - FC10、L- FD10 to L - FD10 for the best, the movement of oil viscosity was 9 ~ 11 was/s/s ( 40℃） ； Lubricating oil should be used in large petrochemical enterprise original packaging products. Bobbin to choose good quality and stable manufacturers; The correct use and maintenance of spindle can reduce the wear and tear of spindle, prolong the service life of the spindle. Broken spindle blade root cause analysis (1) trolley doffing impact; (2) the spindle blade itself has a crack defects; (3) material hardening, aging caused by the unreasonable phenomenon of hard brittle. Elimination method does not use the trolley or cut use trolley number; Due to the material crack of ingot rod or spindle blade itself appear probability is extremely low, only before get in the car, carefully selected, general can solve. Broken ingot ingot, oil or oil leakage cause analysis (1) installation method is not correct in the school work is not required when installing or flange tapping spindle foot, or increase the arm tightened nuts can cause broken bolsters phenomenon; (2) casting ingot foot caused by material or loose, the organization is not close itself has defects such as cracks, porosity, sand holes, and feet are likely to break ingot ingot foot oil or oil leakage phenomenon. Elimination method of spindle is installed on frame reinforced hole, require accurate positioning, reliable fastening, not easy to move. Properly installed bolsters, wrenching moment not greater than 80 nm tighten nut; Bolsters phenomenon of oil spill, oil leakage should be found and treated in time, in order to prevent the fouling yarn. Pole plate up root cause analysis (1) lack of oil caused by needle fall off; (2) bearing wear gap is big. Elimination method reasonable maintenance, the maintenance of spindle, ensure sufficient oil. Pole plate sinks (1) analysis of the causes of spindle early running-in, the wear of the tiny grinding grain is not clear in time, the cone socket type ingot bottom wear or be drilled through; (2) flat ingot bottom type gasket fall off. Method the new spindle running-in period can't open the; And seriously implement new spindle oil change cleaning procedures, and timely removal of grinding particles in the lubricating oil. Big head cause analysis (1) by the rod of the bearing plate force deformation or fracture; (2) pole plate of early wear; (3) the collective doffing. Bobbin elimination method with high quality; Proper maintenance, maintenance of spindle; Ensure the bearing lubrication. Ingot bile loss of elastic support under the elastic analysis of the causes of ingot bravery is mainly used for YD4000 series of spindle, spindle bile lose elasticity is mainly caused by poor oily and dirty. Rule out the use of high quality lubricating oil method; Regularly check oil level height; Fill oil on a regular basis. Through to the spindle structure and problems in use process and cause analysis, to enhance the speed and prolong the service life of the spindle, should be timely to find and deal with problems arising from the spindle in the use of, to the rational use of spindle, cleaning in time, come on, strengthen the daily inspection and maintenance, improving yarn quality, in order to achieve the purpose of prolonging the service life of the spindle. （ Source: the textile equipment online)
