Diaphragm couplings

JMIJ-connection countershaft type diaphragm coupling Installation instructions: 1. Before installation should first check the prime mover and work machine and two axes are concentric, whether two-axis surface wrapping paper and bumps, coupling halves Union rachis whether there is debris in the hole, if there are bumps in the hole edge, if the shaft should be half-coupling clean, handle the bumps with a fine file. Then check the coupling of two and a half bore diameter and length is the same prime mover, a working machine matches the diameter and shaft length dimension. When the general selection, so that the prime mover and work-side half coupling length less than the length of 10- 30mm shaft extension as well. 2. For ease of installation, it is preferable to two and a half coupling on 120--150 incubator or preheated oil bath, make up a large bore size is easily installed. After installation ensure the spindle head must not protrude half coupling end face to flush as well. Distance detection between the two halves of the coupling: along both inner half coupling flange measured 3--4 point readings are averaged, and extended section with two diaphragms measured size of the group and, two by error control within 0-0.4mm range. 3. Alignment: Using a dial indicator to detect the two halves of the coupling flange and the outer end surface of the beating, when less than 250mm cylindrical flange runout value should be less than 0.05mm; when the flange outer than 250mm jitter value should not be greater than 0.08.
