Henan LT type elastic sleeve pin coupling
TAG
LT type elastic sleeve pin coupling is commonly used in the connection of motor and reducer, motor and water pump. It is a non-metal elastic element flexible coupling. Its structure is very similar to flange coupling, but two The coupling of the half couplings does not require bolts but uses pins with rubber or leather sleeves to realize the coupling of the two coupling halves.
LT typeElastic sleeve pin couplingThe structure is relatively simple, easy to manufacture, does not require lubrication, does not need to be bonded with metal vulcanization, easy to replace the elastic sleeve, does not need to move the half coupling, and has the properties of compensating the relative deviation of the two shafts and damping.The elastic sleeve works by compression and deformation. Because the thickness of the elastic sleeve is thin, the volume is small, and the elastic deformation is limited, the elastic pin sleeve coupling can compensate the axis displacement and elasticity, but the allowable compensation amount for the axis displacement is less. The elasticity is weak.The elastic sleeve pin coupling relies on the locking force of the pin group to generate the frictional moment on the contact surface, and compress the rubber elastic sleeve to transmit the torque.It is suitable for high-speed, low- and medium-power water pumps with high rigidity, high centering accuracy, low impact load, and low vibration reduction requirements.
LT type elastic sleeve pin coupling relies on the locking force of the elastic sleeve pin group to generate the frictional torque on the contact surface, and compress the rubber elastic sleeve to transmit the torque, so it is suitable for high speed, and the installation base has good rigidity and right Medium-precision working environment.However, the elastic sleeve is deformed by compression. Due to the small volume and thin thickness of the elastic sleeve, the elastic deformation capacity is limited.Therefore, although the LT-type elastic sleeve pin coupling can compensate the axis displacement and elasticity, the allowable compensation amount for the axis displacement is less, and the elasticity is weak.Therefore, the impact load should be small and the requirements for vibration reduction should not be high.
