Bearing performance of JM diaphragm coupling

JMDiaphragm couplingThe diaphragm is fastened to the shaft sleeve with a pin. Generally, it will not loosen or cause backlash between the diaphragm and the shaft sleeve. This characteristic is a bit like a bellows coupling. In fact, the way the coupling transmits torque is similar. .The diaphragm itself is very thin, so it is easy to bend when the relative displacement load is generated, so it can withstand up to 1.5 degrees of deviation, while generating a lower bearing load in the servo system.The diaphragm coupling can be adapted to work in high temperature (-80+300) and harsh environments, and can move under shock and vibration conditions.

The diaphragm coupling is very delicate and can be easily damaged if it is misused or improperly installed in use.Therefore, it is very important to ensure that the deviation is within the tolerance of the normal operation of the coupling.Diaphragm couplings have a wide range of applications, but the quality of diaphragm couplings is the key to affecting the transmission torque, use cost and service life of the coupling, and the diaphragm couplings on the market seem to be separated Quite a few, strict implementation of the standards to manufacture precision diaphragm couplings, making the cost-effective (performance and price comparison) of the coupling well received by actual users.

What is the performance of the diaphragm coupling pivot bearing?

The armature bearings of the diaphragm coupling must meet their size and related limit speed requirements as much as possible, because the load carried by itself is very large, so it can be said to be able to pull the entire diaphragm coupling. The size is affected by some other directions, and it is necessary to ensure that they are not restricted by the distance inside the wheel or some other places below in the actual working process. Then in this case, the performance of the armature bearing It seems particularly important.

How about the performance of the shaft bearing?

The diaphragm couplings of this kind of bearings are basically the most important parts of the electric motor traction, and can effectively traction the entire electric locomotive and the electric motor, the internal combustion engine transmission system, and even occupy an important position in the process of migration. .This kind of equipment of Guangzhou Linko Automation Equipment Co., Ltd. has better performance.

Before installation, clean the end faces of the two shafts and check the fit of the key grooves on the end faces. After installation, all screws must be checked for normal operation. If they are found to be loose, they must be tightened. Repeat this for several shifts to ensure that they will not loose; During operation, check whether the diaphragm coupling is abnormal. If any abnormality occurs, it must be repaired. In order to prevent the fretting and wear of the diaphragm during high-speed operation, the diaphragm bolt hole should be cracked and damaged. , Solid lubricants such as molybdenum disulfide can be applied between the diaphragms, or the surface of the diaphragms can be treated with anti-friction coatings; in addition, appropriate measures must be taken at various sites that may cause personal and equipment accidents due to the operating diaphragm coupling. Safety protection measures.The coupling diaphragm is composed of several groups of diaphragms that are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is composed of several pieces stacked together. The diaphragms are divided into connecting rod type and different shape of the whole piece type.
