Relevant characteristics of reed coupling

  The reed coupling has good damping characteristics, good elasticity, large changes in elastic elements, compact structure, and reliable, but the price is relatively high, and it is suitable for large changes in load.Shafts with torque vibration are mostly used in diesel engine power devices such as ships, diesel locomotives, diesel generator sets, heavy vehicles and industrial diesel power units to adjust the natural frequency of the torque vibration of the shaft drive system and reduce resonance The amplitude of the time.
    The reed coupling is composed of several reeds of different lengths stacked into a group to form an equal-strength beam structure, of which the longest main reed is directly embedded in the groove between the flowers, and the rest are secondary reeds of different lengths, symmetrical Distributed, the structure is used for two-way transmission (reversible), and asymmetrical is used for one-way transmission.
    The elastic element of the elastic blocking reed coupling is composed of a group of reeds, the reed groups are radially distributed. One end of each group of reeds is a fixed end, which forms a fixed connection with the support block, and the other end is The free end forms a movable connection with the associated parts.When the coupling transmits torque, the movable end of the reed contacting the spline shaft is bent and deformed relative to the fixed end, so that the two halves of the coupling are twisted to a certain angle.In order to increase the cushioning and vibration absorption effects of the coupling, the cavity between the reeds of each group is filled with lubricating oil. Under the action of variable load, the reeds bend left and right to form a pressure change in the oil cavity, forcing the lubricating oil to pass through the reeds. The gaps on both sides flow from one side to the other, creating a greater viscous friction damping.The biggest feature of the coupling is its good damping performance, and the lubricating oil can also reduce the friction and wear that occur directly on the reed due to the bending and deformation of the reed.
