　　1. It has a high power-to-mass ratio, which is especially suitable for connecting high-power power devices; 2. The non-linear change in stiffness between shafts effectively restricts the drift of the magnetic center of the motor; 3. No lubrication or maintenance can fundamentally eliminate gear coupling Vibration caused by tooth surface wear...

　　The reason why both the production and consumption of steel have seen slight growth is that the driving effect of economic growth has weakened and the industrial structure has undergone profound changes.Both the growth of manufacturing industry and the growth of investment have weakened the driving effect of the national economy. The real estate and machinery industries have developed...

　　The elastic pin gear coupling is a pin made of a number of non-metallic materials, which is placed in the mating hole between the two halves of the coupling and the inner surface of the outer ring, and the two halves are connected through the pin to transmit torque. Shaft coupling, elastic pin gear coupling has a certain compensation for two shafts...

　　GL type roller chain coupling has the hardness of steel, excellent corrosion resistance and environmental protection performance.It has a simple structure, convenient assembly and disassembly, no need to move the connected two shafts during disassembly, compact size, light weight, a certain compensation ability, low requirements for installation accuracy, and work...

　　People in both urban and rural areas in my country have the custom of eating moon cakes during the Mid-Autumn Festival. As the saying goes, "August and XNUMXth are full, and Mid-Autumn moon cakes are fragrant and sweet."Moon cakes were originally used to sacrifice to the moon god. The term "moon cake" was first seen in the Southern Song Dynasty Wu Zimu's "Meng Liang Lu". At that time...

　　Flange coupling features: simple structure, low cost, can transmit large torque, does not allow relative displacement of the two shafts, no buffer.Purpose: Widely used in occasions with low speed, no impact, high shaft rigidity and good neutrality.Slider coupling: half coupling...

　　1. Reasonable selection: determine the transmission torque reasonably. Generally, the transmission torque should be determined according to the actual transmission power and actual working speed of the unit. The diaphragm coupling is selected, so that the selected diaphragm coupling can not only meet the torque transmission Requirements, and the lightest structure,...

　　The principle of JQ type-clamped shaft coupling: It uses two clamped shells that are split along the axial direction. The clamped shaft coupling has multiple leaf branches. Like a slider coupling, it has buffering due to its elasticity. The effect of vibration reduction, so it is used more in situations with strong vibration...

　　1. In the initial stage of selecting the coupling, understand the national standards, machinery industry standards, transmission system, such as the type of prime mover, working load, prime mover speed, transmission accuracy, shaft offset, working environment, etc. The reference basis of the shaft. ...

　　The earliest known Mother's Day originated in ancient Greece.On this day, the ancient Greeks paid tribute to Hera, the mother of the Greek gods.Later in the middle of the 17th century, the festival spread to England.On this day, young people who are away from home will return home and give their mothers some small gifts. ...
