Section E article 32 and roll machine universal shaft fracture solution

E article 32 and winder solution 2018 - universal shaft section is broken 10 - 17 Zhang Lingbin ( Shandong liaocheng huarun textile co. , LTD. ) Is the role of article and roll machine in advance and the merger, the multiple small drafting, dogan winding roll after merger, followed by zone draft & le; 1. 112, the main draft & le; 2. 792, for such a small draft draft transmission accuracy of gear train put forward higher request, therefore rieter will E article 32 and winder draft gear train ( See figure 1) Little rock designed modulus of serration cone, cone gear at the same time to the adjacent process and designed to be constant, among them a + b = 91, I + j = 100, l + m = 108, s + r = 87, to ensure the center distance of adjacent rock remains the same. The design can ensure the adjacent rock bite tight, tip clearance constant, speed transmission precision. Figure 1 E 32 E drafting system although this design to ensure the transmission accuracy, but also creates the output shaft position is adjustable, but draft separation is adjusted with the change of the length of fiber quality, that is the position of drawing roller is not immutable, this makes the output shaft and drawing roller is difficult to keep on a straight line, thus rieter between the output shaft and drawing roller added cardan shaft section. But in E article 32 and roll machine in the process of long-term use, we found that the fracture of cardan shaft section often happen, See figure 2) 。 Since the supply of single E article 32 and roll machine frame in Taiwan area is large, the universal shaft section disconnected fracture easily leads to production; Another import expensive cardan shaft section, universal shaft section should be more than 3000 yuan, a domestic cardan shaft section also need to more than 1000 yuan, lead to increased production cost. We will solve the fracture problem of cardan shaft section research. Figure 2 cardan shaft section of the fracture failure of case 1 universal shaft section 1. Section 1 universal shaft lubrication is not good in the process of maintenance, we found that the cardan shaft section because there is no nozzle design, can not add grease to shaft section. Cardan shaft section is short of oil dry grinding is serious, over time, easy to fracture. 1. 2 draft position automatic stop poor sensitivity draft parts stop poor sensitivity, roller, roller round flowers, E article 32 and roll machine parking is not timely, appear even without a stop phenomenon, lead to universal shaft section load increasing, wear, or wring. 2 cardan shaft section fracture prevention measures. 1 regular lubrication cardan shaft section ( 1) First reserve three spare cardan shaft section. （ 2) Replace with three alternate cardan shaft section out of the car up for lubrication of the three universal shaft section. （ 3) For the change of cardan shaft section presents kerosene cleaning, shaft section to remove metal powder ( See figure 3) 。 Cleaning the cardan shaft section (figure 3 4) After cleaning the cardan shaft section presents the oil infiltration (7 days See figure 4) 。 Figure 4 infiltrating the cardan shaft section ( 5) After the infiltration of cardan shaft section daub grease EP1 ( See figure 5) 。 Figure 5 after daub grease cardan shaft section ( 6) With a rubber soft cover, cable tie to apply the universal shaft section of the grease seal ( See figure 6) In case the shaft section place or fly to the oil. Figure 6 seal after the cardan shaft section ( 7) Replace with cardan shaft section after sealing off on lubrication cardan shaft section, and then press ( 2) To ( 6) Steps, complete lubrication lubrication cardan shaft section. （ 8) For 18 months interval, repeat ( 2) To ( 7) The steps to achieve universal shaft section of the periodic lubrication. 2. 2 fine alignment E article 32 and roll machine drawing parts automatic stop when Laura or roller sensitivity for flowers around the roller lift height greater than zero. 5 mm, draft position automatic stop device, a braking signals, make E article 32 and roll machine stops running, avoid cardan shaft section of the load. 3 conclusion good lubrication cardan shaft section, and improve the draft parts stop sensitivity, prolong the service life of the cardan shaft section, reduce machine material.
