The quincunx coupling is used more and more widely, but in many occasions, the details of installing the quincunx coupling are not very clear, resulting in a higher damage rate of the quincunx coupling and a lot of economic losses.The following is the installation technique of the plum blossom coupling.
(1) Before installation, check whether the two shafts of the prime mover and the working machine are concentric, whether there are wrapping paper and scratches on the surfaces of the two shafts, whether there are sundries in the inner holes of the two half couplings of the plum-shaped coupling, and whether the inner holes are ribbed. Whether there are bruises on the edges; if any, the shaft and half coupling should be cleaned up, and the bruises should be treated with a fine file.Then check whether the inner hole diameter and length of the two half couplings are consistent with the diameter and shaft elongation of the prime mover and working machine.In general selection, it is better to make the length of the prime mover and the working machine end half-coupling less than the shaft extension of 2-2mm.
(2) In order to facilitate the installation, it is better to put the two half couplings in the 2-120 incubator or oil tank for preheating, so that the inner hole size increases and it is easy to install.After installation, ensure that the shaft head cannot protrude from the half-coupling section. It is better to be flush.Detect the distance between the two halves of the coupling:
Measure the readings of 3~4 points along the two inner sides of the flange of the half coupling and take the average value, and the sum of the measured dimensions of the extension section and the two diaphragm sets. The error of the two should be controlled within 0~0.4mm.
(3)找正:用百分表检测两半联轴节法兰盘断面和外圆跳动,当法兰盘外圆小于250mm时跳动值应不大于0.O5mm;当法兰盘外圆大于250mm时,跳动值应不大于0.08mm。
(4) Install the bolts: insert the bolts from the outside of the small hole of the flange, pass through the outside of the large hole of the other flange, put on the buffer sleeve and elastic washer, screw on the nut, and tighten the nut with a wrench.If the installation is unsuitable or if it is removed and replaced, it will not damage the shaft and the half coupling; after installation, it is better to rotate freely without holding back.
In addition, in actual use, check whether the nut of the plum-shaped coupling is loose or falling off before starting the equipment. If so, tighten the nut with a wrench in time.
