LB type tire coupling is one of the couplings we supply. Its models are relatively complete, generally divided into two categories: convex type and concave type. Convex type is further divided into three categories: skeleton integrated type, boneless integrated type and radial notched type. Their common feature is to bolt the tire ring to connect the two halves of the coupling to achieve the connection of the two axles. The tire coupling has high elasticity, the ability to compensate the relative displacement of two axles is larger, and has good damping, and the structure is simple, does not need lubrication, assembly and maintenance are more convenient. Tire coupling in use sometimes there will be imbalance phenomenon, the following for you to introduce.

LB type tire coupling due to a variety of reasons to make its center of mass or inertia spindle and its axis of rotation do not coincide, when running will produce unbalanced centrifugal inertia force, centrifugal inertia force couple and dynamic deflection (mode) phenomenon, known as the rotor imbalance phenomenon, this imbalance phenomenon causes shafting vibration, thus affecting the normal work and service life of the machine, so it must be paid attention to. In order to correct or greatly reduce the unbalance of LB type tire coupling, the appropriate balance class shall be selected as required and achieved by adding or reducing the appropriate mass on the specified balance (correction) plane of the coupling after the product is manufactured and installed on the machine. This process is called balance correction, or equalization. The degree of unbalance (unbalance U) is usually expressed by the product mr Of the mass m of the rotor and the distance r from the center of mass to the axis of rotation of the rotor, which is called the mass diameter product. Also expressed in terms of mass product per unit mass, called eccentricity e(not eccentricity in the geometric sense) Mass product mr Is a relative quantity related to the mass of the rotor, while eccentricity e is a quantity independent of the mass of the rotor. The former is intuitive and often used for balancing operation of a specific given rotor, while the latter is used to measure the pros and cons of the rotor balance or detect the balance accuracy. The balance grade standard of the tire coupling is evaluated according to e.

The above content is the cause of unbalanced phenomenon of LB type tire coupling. I hope this article will be helpful for you to use. Manufacturers have rich experience in coupling, have the conditions and advantages of designing products and mass production, and can meet the various needs of users.
