Star elastic coupling

  • What are the commonly used flexible couplings without elastic components?

    • 　　1. Flange couplings (1) Ordinary flange couplings are connected by bolts with reamed holes, and are centered by bolts of reamed holes (corresponding to reamed bolts), and rely on the shear resistance of bolts to transfer Torque. 2. The flange coupling (2) is connected by ordinary bolts...

  • Three points need to be considered when selecting the coupling

    • 　　First of all, the first point is to determine the form of the coupling according to the application (what driven equipment, what is it used for, and what are the requirements for the whole set of equipment?) according to the equipment. ...

  • About the installation of gear couplings

    • 　　There are many types of gear couplings, consisting of internal gear rings with the same number of teeth and flange half couplings with external teeth.However, there are two basic forms: 1. Combination of internal and external teeth; 2. Combination of face teeth. ...

  • What are the advantages of the Oldham coupling over other couplings?

    • 　　The Oldham coupling uses polyurethane plastic as the elastic element and is tightly combined with the two half coupling main body.The Oldham coupling is composed of two half couplings with grooves on the end faces and an intermediate disc with protruding teeth on both sides.Because the protruding teeth can slide in the groove, so...

  • Overview of flange coupling

    • 　　Flange coupling is the most widely used rigid coupling, consisting of two half couplings and connecting bolts.There are two centering methods for flange couplings: one is to match the tenon on one half of the coupling with the groove on the other half of the coupling. ...

  • Coupling is an important device for mechanical connection

    • 　　General machinery is composed of prime mover, transmission machine and working machinery. These three parts must be connected to work. The coupling is an important device that connects them. The coupling is mainly used for the connection between the two shafts. , It can also be used for shafts and other...

  • How to choose an economical and affordable coupling

    • 　　Due to the different types, types and specifications of the coupling structure, material, size and accuracy, the cost and manufacturing cost vary greatly.The cost of couplings with general accuracy requirements is lower than that of high-precision couplings, and the cost of couplings with simple structure and good manufacturability is lower than...

  • The difference between cast steel and forged steel

    • 　　Forged steel refers to various forging materials and forgings produced by forging methods.The quality of forged steel parts is higher than that of cast steel parts, and can withstand large impact forces. The plasticity, toughness and other mechanical properties are also higher than those of steel castings. Therefore, any important machine...

  • Improvement of Drum Gear Coupling

    • 　　Among a wide range of couplings, the drum gear coupling has the advantages of small size, large transmission torque, strong ability to absorb coupling errors, and excellent durability. It is the most common coupling transmission in medium and heavy machinery. Parts of the shaft,...

  • Lubrication method of drum gear coupling

    • 　　Good lubrication is a necessary guarantee for the safe and reliable operation of the drum gear coupling, as well as a necessary condition for reducing wear.Most of the high-speed drum gear couplings are lubricated by lubricating oil. The lubricating oil needs to be filtered by a high-precision oil filter with a filtration degree of less than 10 microns. The tooth surface...
