About Tyre Coupling classification and characteristics

   Definition
   Tyre Coupling is divided into two major categories of convex and concave, convex with a skeleton is divided into integral, integral and radial boneless cuts three. Ring inside the tire vulcanization bonding method and integrated steel skeleton, the skeleton of the bolt hole welded nuts. When mounting the coupling halves with bolts and a flange connection, tighten the screws of the tire depend on the flange end face of the frictional force generated between the torque transmission, the tire ring at the work place torsional shear deformation, the Tyre Coupling With its high flexibility, the relative displacement of two-axis compensation capacity is large, and has good damping, and the structure is simple, without lubrication, disassembly and maintenance more convenient.
   The disadvantage is not high carrying capacity, larger dimensions, with the two axes relative twist angle increases twisted shape of the tire, the axial dimension decreases slightly greater in the two axes of the additional axial force, the bearing load increase and decrease life. Coupling high speed tires, the tire outer outward expansion of the centrifugal force, will further increase the additional axial force. To this end, measures should be taken in installing the coupling, so that the stress in the direction of the tire and the stress generated when the work in the opposite direction, to offset part of the additional axial force, to improve the work of couplings and two bearings and conditions.
   Classification and Characteristics
    Tyre Coupling main models: UL Tyre Coupling, LLB Tyre Coupling, LLA Tyre Coupling, DL polygonal rubber coupling, LAK saddle-shaped blocks and other types of flexible coupling, UL type, LLB type, LLA type is more commonly used in several models. Here we highlight the characteristics of these types of couplings: UL tire coupling specifications are UL1-18, nominal torque :10-25000, allowable speed :5000-800, shaft diameter: 11 -180mm, shaft hole length :22-302mm, weight :0.7-818, Material: 45 # round steel, cast steel, forged steel. UL tire coupling has good shock absorption cushioning properties, to solve the general coupling buffer effect can not be achieved.

COUPLINGS

     LLB Tyre Coupling size
     LLB Tyre Coupling size: LLB1-13 tires Body Type: LTB1-13, standard number (JBT10541-2005) original standard (JBZQ4018-85) Material steel, cast iron and 45 # round steel, other materials are also factory can be customized, nominal torque :10-20000 allowable speed: 5000-1000 shaft diameter: 6-200mm shaft hole length: 16-382mm, quality :0.4-340. LLB tire couplings used for metallurgical equipment, it is also known as metallurgical equipment tire couplings. LLB metallurgical equipment tire coupling is a highly flexible coupling, with good shock absorption cushioning and superior performance of inter-axis offset compensation, suitable for humid, dusty, shock, vibration, reversing more frequent change and start working conditions, and all easy disassembly.
    LLA Tyre Coupling specifications  
    LLA tire coupling metallurgical equipment specifications: LA1-11 :10-20000 Nominal torque allowable speed :5000-800 Shaft diameter: 5-180 shaft hole length :14-302 Weight :0.35-373kg Material: cast iron steel, suitable for humid, dusty, shock, vibration, frequent reversing and start changing working conditions and full disassembly convenient, without lubrication, durable and reliable.
    UL Tyre Coupling specifications
    Three kinds of couplings, UL tire coupling the most commonly used, three kinds of tire tire coupling body are not the same, UL-and LLB tire tire coupling body are not open of, LLA tire coupling tire body is open, under the same model, LLB tire body than the UL tire body thicker, Germany Lingsi tire coupling body with good quality tires, rubber internal distribution nylon thread, nylon fabric, so the tire body weight, reliable, flexible, long life and other characteristics, it is generally the tire body does not have.
