DJM type elastic diaphragm coupling
DJM type elastic diaphragm coupling is mainly composed of two protruding teeth that are closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element undergoes corresponding elastic deformation, which plays a role of automatic compensation. .
DJM型弹性膜片式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。
The DJM type elastic diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces, and the diaphragms are divided into connecting rods. And different shapes of the whole piece.
The DJM type elastic diaphragm coupling is produced in the production line mode of modern numerical control processing equipment.
DJM type elastic diaphragm coupling has the following characteristics: flower-shaped elastic coupling has simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions, plum-shaped elastic coupling is stable and has good performance Vibration damping, buffering and electrical insulation performance.The quincunx elastic coupling has greater axial, radial and angular compensation capabilities. The polyurethane elastic element of the quincunx elastic coupling is oil-resistant, has a large load-bearing capacity, and has a long service life. The coupling does not need lubrication and requires maintenance workload It can run continuously for a long time.

The characteristics and maintenance methods of gear couplingGear coupling is a kind of removable rigid coupling.It uses internal and external tooth meshing to realize the torque rotation and movement transmission between the two halves of the coupling. It is suitable for the transmission shaft system connecting two concentric shafts, and has the performance of relatively compensating the relative displacement of the two shafts.Its structure is shown in Figure XNUMX. It is composed of main parts such as inner gear ring, gear shaft sleeve and end cover.
