Shaanxi LMZ-I (formerly MLL-I) split brake wheel plum-shaped elastic coupling

LMZ-I (formerly MLL-I) type split brake wheel plum blossom elastic coupling is mainly composed of two protruding teeth closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic The corresponding elastic deformation of the component plays a role of automatic compensation.

LMZ-I(原MLL-I)型分体式制动轮梅花形弹性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。

LMZ-I (formerly MLL-I) type split brake wheel plum-shaped elastic coupling has the following characteristics:

(1) Stable work, with good vibration damping, buffering and electrical insulation properties.

(2) Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions.

(3) It has large axial, radial and angular compensation capabilities.

(4) Polyurethane elastic elements are resistant to oil, have large carrying capacity and long service life.

(5) The coupling does not need to be lubricated, the maintenance workload is small, and it can run continuously for a long time.

Introduction to the correct installation method of LMZ-I (formerly MLL-I) split brake wheel plum-shaped elastic 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 bumps on the surfaces of the two shafts, whether there are debris in the inner holes of the two half couplings of the plum coupling, and whether the edges of the inner holes are 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 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, the two half couplings are placed 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 face 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 3--4 readings 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. 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 disassembly and replacement, without damaging the shaft and half coupling, it is better to rotate freely after installation.

5. Instructions for operators:Plum-shaped elastic couplingBefore starting the equipment, check whether the nut of the plum blossom coupling is loose or falling off. If so, tighten the nut with a wrench in time.
