Application characteristics and structure of tire coupling

　　Application characteristics and structure of tire coupling

　　The common and different points of the two main types of tire couplings are convex and concave.Convex shapes are divided into three types: integral with skeleton, integral without skeleton, and radial incision.The inner side of the bead is bonded to the steel frame through vulcanization, and nuts are welded to the frame bolt holes.When assembling, the bolt is connected with the flange between the two half couplings. The torque is transmitted by the friction force between the tire and the flange end surface caused by the tightening of the bolts, and the torsional shear deformation occurs when the rim is working.Therefore, the tire coupling has high elasticity, strong ability to compensate the relative displacement of the two shafts, and good damping performance.Moreover, the structure is simple and does not require lubrication, assembly, disassembly and maintenance.This is more convenient.The disadvantage is that the bearing capacity is not high, and the shape and size are large.As the relative torsion angle of the two shafts increases, the shape of the tire is distorted, and the axial dimension is slightly reduced.Will generate additional axial force on the two shafts, thereby increasing the load on the bearing and reducing the service life.When the coupler is running at high speed, the centrifugal force on the outer edge of the tire expands outward, further increasing the additional axial force.Therefore, when installing the coupling, measures should be taken to make the direction of the stress of the tire opposite to the direction of the stress generated during work to offset some additional axial forces and improve the working conditions of the coupling and the two bearings.

　　Their common feature is that the tire ring is bolted to the two halves of the coupling to realize the connection of the two shafts.

　　1. The tire coupling does not need to be lubricated, which effectively saves maintenance costs;

　　2. The wear parts of the tire coupling connection are clear at a glance, and can be judged directly without stopping, so it can be easily repaired and replaced;

　　3. It is very easy to replace and install the worn parts of the tire coupling.When replacing tires, the motor and equipment are not disturbed;

　　4.The two drive shafts of the tire coupling allow a large misalignment, allowing 4 degrees of angular displacement, 6 mm of parallel displacement and 8 mm of axial displacement.

　　5. The vibration absorption performance of the tire coupling is very good, the coupling can "curl" about 12 degrees to absorb the vibration in the system;

　　6. Tire coupling can solve the torsional vibration problem by choosing tires with different stiffness.

　　7. Due to the bidirectional winding of the load in the steel wire rope, the tire coupling can realize bidirectional driving.

　　8. The tire coupling has no gap at all, which is an ideal choice for reverse drive, especially in gear transmission;

　　9. The tire coupling is made of fire-proof or anti-static tires, which can be used in fire-proof and anti-static occasions.

　　10. The tire-type lathe is equipped with various flanges, FHBEM Position, axles, high-speed axles and flywheels;

　　11. The tire coupling can adopt taper sleeve or short taper sleeve, with compact transmission structure;

　　12. The tire structure is simple, easy to assemble, and the tire body can be changed without axially moving the coupling.

　　The tire coupling has good axial, radial and angular offset compensation performance, good damping performance, simple structure, stable and reliable operation, no noise, no lubrication, convenient maintenance, simple loading and unloading, good processing performance, and low cost. It can be derived into a variety of structural forms, with good versatility, wide application range, and easy promotion.One of the outstanding advantages of the coupling is that it only needs to be installed once. When replacing the elastic element, there is no need to move the half coupling, which can reduce auxiliary working time and improve production efficiency. It is especially suitable for axis alignment that is difficult to install. It is necessary to reduce the auxiliary devices as much as possible, and the production efficiency is high. It is especially suitable for the difficult installation of shaft alignment, and it is required to reduce the auxiliary working environment as much as possible.Tire coupling is a new type of high-performance coupling in our country.It concentrates the advantages of the different structures of the standard elastic coupling, such as the advantages of the plum blossom elastic coupling: the elastic element is extruded, the structure is simple, and the reliability is high.The utility model overcomes the shortcomings of the plum blossom elastic coupling: when replacing the elastic element, the movable half coupling and the double flange plum blossom elastic coupling can change the elastic element without the movable half coupling, but the structure is complicated and the cost is High, when the mass and moment of inertia increase, the application range is limited.When the torque is the same, the radial dimension is much smaller than the elastic sleeve pin coupling, the mass is lighter, and the moment of inertia is small.

　　The above is the special purpose of tire coupling.Mastering these main characteristics is very useful for everyone.Therefore, everyone should also pay attention to coupling as a small project.
