    How to install and use diaphragm coupling

    Release Date: 2016-03-31 Publisher: Ever-Power Machinery

    The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the sleeve with a pin and generally will not loosen or cause backlash between the diaphragm and the sleeve.Some manufacturers provide two diaphragms, and some provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.The difference between the single diaphragm coupling and the double diaphragm coupling is the ability to handle various deviations. In view of the complex bending of the diaphragm, the single diaphragm coupling is not suitable for eccentricity.The double diaphragm coupling can bend in different directions at the same time to compensate for eccentricity.

    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 coupling, and whether there is any edge of the inner hole. If there are bruises, 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 let the length of the prime mover and the working machine end half coupling be less than the shaft elongation of 10-30mm.

    2. In order to facilitate the installation, it is good to put the two half couplings in the 120-150 incubator or oil tank for preheating, so that the inner hole size increases and it is easy to install.After installation, the shaft head should not protrude from the end surface of the half coupling, it is better to be flush.Detect the distance between the two halves of the coupling: take the average of the readings of 3 to 4 points measured along the two inner sides of the flange of the half coupling, and the sum of the measured dimensions of the extension and the two diaphragm sets, two The error is controlled within the range of 0-0.4mm.

    3.找正:用百分表检测两半联轴节法兰盘端面和外圆跳动,当法兰盘外圆小于250mm时跳动值应不大于0.05mm;当法兰盘外圆大于250mm时,跳动值应不大于0.08。

    4. Install the bolts: insert the bolts from the outside of the small hole in the flange, pass through the outside of the large hole of the other flange, put on the buffer sleeve, elastic washer, twist the nut, and tighten the nut with a wrench.If it is not suitable for installation or removal and replacement without damaging the shaft and half coupling, please make tools and install them according to Figure 3 to Figure 7.After installation, it is better to rotate freely.
