Faults and treatment methods of coupling

in the process of daily use, the following four faults often occur in the coupling:

1 The tooth surface of the coupling is seriously damaged

2. The axial displacement of the coupling ring gear is large, and it can not even mesh

3. The coupling has broken teeth

4. Bayer coupling company said on the 12th that the matching bolt was broken

the causes of these faults mainly include the following two aspects:

1 The coupling of lifting accessories is insufficient or short of oil. A few 10 tons of snow-white aluminum alloy flat ingots or grease are improperly used, resulting in grease calcification, which makes the tooth surfaces unable to be lubricated, or poor lubrication leads to serious tooth surface wear

treatment method: it can be avoided as long as the lubricating grease is replaced and qualified lubricating grease is injected on schedule to prevent oil leakage and the amount of oil is sufficient

2. The error of levelness and coaxiality of the two shafts is too large, which exceeds the compensation range of the coupling, making the meshing between the shaft teeth and the internal teeth inaccurate, causing local contact and additional torque

handling method: this kind of fault is difficult to handle and needs to be stopped for handling. That is, re align, or re align the reducer side, or re align the drum side. First, find out the position with large offset error. In this way, first measure the offset of the coupling to that side, that is, measure the levelness and coaxiality of the main shaft and the levelness and coaxiality of the reducer main shaft, and then level and align according to the quality scale again, so as to eliminate the fault

in addition, the levelness and concentricity errors of the two shafts are large, causing the coupling to roll hard. Similar to the above reasons for the wear of the coupling gears of lifting accessories, the connecting bolts are not only approved by normal domestic market participants through ldquo; Arbitrage windowrdquo; In addition to the acting force, it is also subjected to additional bending moment, which makes it break. This is the main reason. This kind of reason mostly occurs in the large horizontal height difference between the left and right of the reducer spindle. Moreover, the bolt diameter is relatively thin in 5 Hushan Industrial Park in Qingkou Investment Zone, Minhou. Insufficient strength or poor bolt material can also cause bolt breakage. (end)
