Differentiation and identification method of Aral woodworking machinery coupling products utb2am39 therefore, although the elastic sleeve pin coupling can compensate the axis displacement and elasticity, the allowable compensation amount for the axis displacement is small and the elasticity is weak. The elastic sleeve pin coupling generates the friction torque on the contact surface by the locking force of the pin group, and compresses the rubber elastic sleeve to transmit the torque. It is suitable for medium and small power shafting transmission with good rigidity of mounting base, high centering accuracy, small impact load and low requirements for vibration reduction

will the phenomenon of "god horse" appear when the heating time of elastic pin coupling is too long? The heating of elastic coupling forgings will cause cracks in the workpiece during heating, resulting in cracks in the workpiece after machining and scrapping. If there is banded carbide on the surface of the elastic coupling, the hardness and structure after quenching and tempering will be uneven and easy to deform, which is also a defect that pearlite and ferrite have banded structure along the processing deformation direction. However, if the annealing is under heated or the temperature is low, if the damage occurs at the joint with the collet, the pearlite cannot be completely spheroidized, which is not conducive to cutting and subsequent heat treatment. Overburning cannot be remedied. Failure to remove beryllium oxide will affect machining. Overburning refers to the phenomenon of metal oxide or local melting due to too long heating time and too high temperature

houzhe transmission believes that the coupling is a component that connects the two shafts axially and transmits torque and motion, and has a certain ability to compensate the offset of the two shafts. In order to reduce the vibration of the mechanical transmission system and reduce the impact peak load, the coupling should also have a certain cushioning and damping performance. Sometimes the coupling also has the function of overload safety protection

the actual heating temperature required by the coupling can be calculated according to the interference value of the coupling and the shaft and the requirements of the above-mentioned manufacturer when the shaft sleeve is installed after the coupling is heated. Houzhe transmission believes that from the perspective of metallography and heat treatment, the heating temperature of the coupling cannot be increased arbitrarily, and the recrystallization temperature of the steel is 430 ℃. If the heating temperature exceeds 430 ℃, it will cause changes in the internal structure of the steel. Therefore, it is basically sufficient to set the upper limit of the heating temperature at 400 ℃

when designing the machine, it is specified that there is an allowable deviation value for the centers of the two shafts. From the assembly point of view, as long as the coupling can safely and reliably transmit torque, the greater the allowable deviation of the two shaft centers, the easier it is to meet the requirements during installation. However, from the perspective of installation quality, the smaller the deviation of the center line of the two shafts, the more accurate the alignment, the better the operation of the machine and the longer the service life
