Shaanxi ML plum blossom coupling

ML plum blossom coupling has the following characteristics: stable operation, good vibration damping, buffering and electrical insulation properties.The structure is simple, the radial dimension is small, the weight is light, and the moment of inertia is small. It is suitable for medium and high speed applications. The plum-shaped elastic coupling has large axial, radial and angular compensation capabilities. The polyurethane elastic element is oil-resistant and has a large load-bearing capacity. , The service life is long, the coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.

ML型梅花联轴器主要适用于起动频繁、正反转、中高速、中等扭矩和要求高性的工作场合，例如：冶金、矿山、石油、化工、起重、运输、轻工、纺织、水泵、风机等。工作环境温度 -35℃～ 80℃，传递公称扭矩25～12500Nm，许用转速1500～15300r/min。 

How to install and use ML plum blossom coupling

1 Before installation, check whether the two shafts of the prime mover and the working machine are concentric, and whether there are wrapping paper and bruises on the surfaces of the two shafts.

Plum couplingWhether there is debris in the inner holes of the two half-couplings, whether there are bruises on the edges of the inner holes, if any, clean the shaft and half-couplings, and handle 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.In general selection, it is better to make the length of the prime mover and the working machine end half-coupling less than its shaft elongation 10-30mm.

2 In order to facilitate the installation, it is better to put the two half couplings in a 120150 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 face of the half coupling, it is better to be flush.Detect the distance between the two halves of the coupling: 34 points of readings measured along the two inner sides of the flange of the half coupling are averaged, and the sum of the measured dimensions of the extension and the two diaphragm sets is controlled by the error. Within the range of 0-04mm.

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005mm；当法兰盘外圆大于250mm时，跳动值应不大于008。

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 the operator: Before starting the equipment, check whether the nut of the plum coupling is loose or falling off. If so, tighten the nut with a wrench in time.The load line valve should be opened after starting the equipment with no load for 1 minute; the shutdown sequence is reversed. (Please brush the outside of the coupling with oil once a month).

6. Practice has proved that if the installation, maintenance and operation are carried out according to the instructions and requirements, the number of daily starts of the plum coupling is 15 times,
