Introduction to the cable car universal coupling maintenance

Introduction to the cable car universal coupling maintenance - 2018 08 - 05 abstract: this article mainly from baishi mountain scenic feiyun mouth cableway maintenance of universal coupling, mainly introduce the maintenance of the process of the universal coupling and matters needing attention. Key words: cableway; Universal shaft; Maintenance; Maintenance feiyun mouth cableway is hebei Lai source baishi mountain scenic spot, begin to prepare to construct in 2010, approved by the state ministry of construction, completed in April 26, 2013 single circulating fixed rope clips pulse group box type ropeway, cableway all inclined long 567 meters, 312 meters elevation difference, along the way, a total of eight stent 12 box ( 3 a group box, a total of four groups of box) 。 A, the purpose of the universal coupling universal coupling advantage of the characteristics of its organization, make the two axis is not in the same axis, the presence of axis Angle can be achieved by coupling of two continuous rotary shaft, and transmission torque and reliably. Universal coupling of the biggest features are: its structure have larger angular compensation capacity, compact structure, high transmission efficiency, the overloaded power transmission at high speed, some coupling and buffer, vibration and enhance the role of shaft system dynamic performance, the universal coupling of maintenance is particularly important. Second, the universal coupling overall demolition universal coupling between the brake and the speed reducer, the maintenance should be overall demolition, to break up the maintenance, when remove the first high speed brake by hand chain hoist crane, make it a little stress, avoid is disassembled cause damage to the brake, coupling with same lifting chain, then remove and high speed brake and reducer connection flange bolts, at this time, should be paid attention to when removing bolt, should be in the flange bolt hole completes the corresponding mark, so that the installation position, after to remove all bolts, using chain speak universal coupling to the bus, use the rope to place it on the floor. Three, universal shaft coupling of split first, pull out spline shaft, at this time should be paid attention to, if there is no arrow, universal coupling outer side or arrow wear away, should mark, convenient in installation position correctly, clean grease spline shaft, spline shaft should be carefully observed at this time have any damage, cracking. Flange of disassembly, because of the length of the Allen wrench is limited, so, by adding casing on hexagon, makes it easier to remove bolts, in use when remove the casing to fix universal coupling, convenient to remove the flange bolts, all bolts after removal of all separate the universal coupling and flange, flange for cleaning, if discover rust, should be timely. Flange fork remove next, at this point we can see the spider, the spider's surface to wipe clean, take a closer look at ever have rust, damage, cracking, use sand paper to grind there is damage or corrosion. Will remove cross axis, use gasoline to thoroughly clean the spider, cleaning personnel should wear protective gloves, in order to avoid damage gasoline rivals, cleaning can be divided into rough washing and fine washing, rough washing, used in the oil brush to remove grease or adhesive material, fine cleaning, slowly rotating in the oil, cleaning the cross shaft, bearing should turn slowly, carefully clean, clean the spider at the same time, the universal coupling for other parts to clean, wipe, after cleaning, coating on the cross shaft and bearing grease immediately. All parts is clean, the universal coupling assembly, daub grease to each connection, convenient in installation, assembly, after the completion of the docking spline shaft, should find the position of the arrow is on or ready to mark the location of the docking, the whole assembly has been completed, the universal coupling fill equipment antirust paint off paint, paint dry after universal coupling with the rope to the big car, reoccupy hand chain hoist, installation to its original position, find the flange before mark for installation. Overall after the installation, inject grease on universal coupling, all completed, low-speed test, after the test, the normal work of the universal coupling, the maintenance work is done. Four, conclusion universal coupling the whole maintenance process takes 1 hour 30 minutes, universal shaft coupling is very important for the maintenance, in the process of daily maintenance, oil should be 500 hours, the runtime cases should be once every two months lubrication, refueling, the screw hole of the bearing face oil screw, injection with high pressure oil gun to overflow, the universal coupling 3 months will be commonly used for maintenance, split, cleaning, check whether there is any damage on the spider and joint, such as a rusted-out timely fill the equipment antirust paint, indentation and normal wear phenomenon is found, it should be replaced in a timely manner. When the job is running, often should observe whether universal coupling is abnormal radial swing or the phenomenon such as bearing heating, found that these phenomena should be timely maintenance. In may be due to the operation of the universal coupling of personal and equipment accidents caused each place, must be equipped with safety protection measures. （ Source: white stone mountain cableway)
