Shaanxi LMZ-Ⅱ (formerly MLL-Ⅱ) plum-shaped elastic coupling with brake wheel

LMZ-Ⅱ (formerly MLL-Ⅱ) type brake wheel plum-shaped elastic coupling is mainly composed of two convex teeth closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element Corresponding elastic deformation occurs, which plays a role of automatic compensation.

LMZ-Ⅱ(原MLL-Ⅱ)型带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-Ⅱ (formerly MLL-Ⅱ) plum blossom elastic coupling with brake wheel has the following characteristics:

(1) Stable work, with good vibration damping, buffering and electrical edge performance.

(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.

Seven main points of hot-installation of LMZ-Ⅱ (formerly MLL-Ⅱ) plum-shaped elastic coupling with brake wheel:

XNUMX. Before heating, first check whether the plum blossom coupling is in a pair with another coupling. If it is out of order in the installation of the same unit, it is necessary to find out the pair mark or number.

Two, checkPlum couplingWhether the mating surface has defects such as burrs and scratches.

30. Record the temperature rise and current value regularly, and the temperature rise does not exceed XNUMX degrees per hour.

100. After the temperature rises to XNUMX°C, the investigators should always pay attention to temperature changes.

XNUMX. When measuring the aperture value of the sample rod, be sure to cut off the power before proceeding.

XNUMX. Qualified fire-fighting equipment should be placed in the heating area for emergencies.

XNUMX. After the plum blossom coupling is hot-installed on the shaft, cold water should be used to pour the journal to cool it to prevent the heat from spreading to the armature and affecting the insulation performance.
