Generally speaking, the elastic pin is used on the TL-type elastic sleeve pin cardan shaft, which mainly plays the role of driving the two half couplings to fix and transmit.And whether the hardness of the pin will change the torque of the cardan shaft, for the standard data, the fixed number, size and material of the backrest pin will not change the torque too much, and if the number increases or the pin of the cardan shaft The larger the size, the torque of the cardan shaft will change.

　　When processing cardan shafts, you must follow the data of the National Ministry of Machinery Standards. If the torque of the cardan shaft designed by yourself is too large or the torque is too small, it will affect the use of the cardan shaft.Because if the torque does not meet the rated use requirements, the torque or speed of the cardan shaft will not meet the use requirements, which will cause the cardan shaft to twist and break during operation.
