1. Before installation, check whether 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 debris in the inner holes of the two half couplings of the LMZ-I plum blossom coupling, and the inner holes Whether there are bruises on the edges, if any, clean up the shaft and half coupling, and treat the bruises 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.

　　2. In order to facilitate the installation, it is better 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, ensure that the shaft head cannot protrude from the end face of the half coupling, and 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 of 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 the installation is unsuitable or it is removed and replaced without damaging the shaft and the half coupling, it is better to rotate freely after installation.

　　5. Instructions for operators: Before starting the equipment, check whether the nut of the LMZ-I torx coupling is loose or falling off. If so, tighten the nut with a wrench in time.

　　LMZ-I plum blossom coupling installation and disassembly:

　　1. Wipe clean the dust and dirt on the surface of the installation shaft, and apply a thin layer of engine oil or lubricant.

　　2. Clean the inner hole of the coupling, and apply oil or lubricant.

　　3.Insert the coupling into the mounting shaft; if the hole diameter is too tight, be careful not to hit the installation with a hammer or hard metal.

　　4. After the positioning is completed, first use a torque wrench (the specified tightening torque 1/4) to gently tighten the screws in the diagonal direction.

　　5. Increase the strength (1/2 of the specified tightening torque) and repeat the 4 steps.

　　6.Tighten the tightening torque according to the specified tightening torque.

　　7.Afterwards, tighten the fixing screws in the circumferential direction.

　　8. When disassembling the plum blossom joint, please proceed with the device completely stopped; loosen the locking screws in turn
