Introduction of tire coupling knowledge

Talk about the balance of tire coupling:

Why is it that the former is more intuitive and is often used for specific balancing operations of a given rotor, while the latter is used to measure the pros and cons of rotor balance or to detect balance accuracy. The balance grade standard of tire couplings is evaluated by e.Because the tire coupling due to various reasons makes its center of mass or inertial principal axis not coincide with the axis of rotation, it will produce unbalanced centrifugal inertial force, centrifugal inertial couple force and dynamic deflection (mode of vibration) during operation, which is called rotor This imbalance phenomenon will inevitably cause the vibration of the shaft system, which will affect the normal operation and service life of the machine, so we should pay attention to it.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 product of mass diameter.It is also expressed by the product of mass diameter per unit mass, called eccentricity e (not geometrically eccentric.) The product of mass diameter mr is a relative quantity related to the mass of the rotor, while the eccentricity e is a value that has nothing to do with the mass of the rotor.的量。 The amount.

The tire coupling for LLA metallurgical equipment is a highly elastic coupling with good shock absorption and excellent inter-axis offset compensation performance. The working temperature is -20 to 80 degrees Celsius and the transmission torque is 10 to 20000N. M, suitable for wet, dusty, shock, vibration, variable forward and reverse and frequent starting working conditions, and it is easy to disassemble and assemble, does not need lubrication, and is durable.The non-standard coupling is made according to the needs. When overloading, the clamping flap of the half coupling will work, and no malignant accident will occur. Its structure is marked as M, and the standard half coupling structure is K type. It can no longer be marked in the display.
