Plum blossom elastic coupling is a common coupling

Plum coupling主要适用于起动频繁、正反转、中高速、中等扭矩和要求高可靠性的工作场合，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。梅花形弹性联轴器具有以下特点：
(1)Plum elastic couplingStable and reliable 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) High-strength polyurethane elastic elements are resistant to oil, have large carrying capacity, long service life, and reliability.
(5) The coupling does not need to be lubricated, the maintenance workload is small, and it can run continuously for a long time.
The structure of the plum blossom coupling affects the use of the plum blossom coupling in the transmission industry.
Plum elastic couplingThe working principle is to install an integral quincunx elastic ring between the claws of two half-couplings of the same shape to realize the connection of the two coupling halves.This coupling is widely used in water pumps, oil pumps, machine tools and other industries.The power is transmitted through the squeezing between the claw and the elastic ring, and the relative deviation of the two shafts is compensated by the elastic deformation of the elastic ring to realize vibration reduction and buffering.The plum blossom flexible coupling belongs to the category of general mechanical parts. It is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms so that they can rotate together to transmit torque.
In high-speed and heavy-duty power transmission, some plum elastic couplings also have the function of buffering, damping and improving the dynamic performance of the shafting.Moreover, the elastic body in the plum blossom elastic coupling has the function of protecting the machine when the machine is running. When the machine is told to run, its torque reaches the range that the coupling cannot bear. The elastic body will have problems first, which will remind you of the machine's problems and greatly reduce the phenomenon of machine damage.The plum blossom elastic coupling has the following characteristics: the plum blossom elastic coupling has simple structure, small radial size, light weight, and small moment of inertia. It is suitable for medium and high speed applications. The plum blossom elastic coupling is stable and reliable, and has good vibration reduction, Buffer and electrical insulation properties.
The following describes the steps required by the coupling manufacturer to install and position the plum blossom coupling. Cleaning: wipe off the dust on the surface of the installation shaft, apply a thin layer of oil or lubricant, clean the inner hole of the coupling and Apply oil or lubricant, and insert the coupling into the installation shaft; if the hole diameter is too small, please be careful not to hit the installation with a hammer or hard metal.Position of the positioning screw: Two 90° screw holes are machined on the outer circle of the coupling.The set screw fixes the coupling to the shaft through these two holes.This is a relatively common fixation method.Since the front end of the screw is in contact with the shaft, the shaft may be damaged or difficult to disassemble. Tighten the screw position: cut off the joint on the coupling.
Utilize the tightening force of the coupling factory screw to deform the slit and secure the shaft tightly.This method is easy to install and disassemble, and will not cause damage to the shaft.This is a very common fixing method, keyway positioning: For high torque transmission requirements, in order to prevent axial sliding, the installation and positioning of the torx coupling are usually combined with positioning screws and fastening screws.
