The invention relates to the technical field of transmission shaft assemblies of transport vehicles, and discloses a transmission shaft fixing device of a fan transport trailer. An output shaft, an input shaft and a first flange are designed in a penetrating mode and fixed through flower type nuts, and the output shaft and the input shaft are fixed to the first flange through the flower type nuts under the action of lock pin pieces; by means of the structure, the output shaft and the input shaft can both achieve large-driving-force and large-torque transmission, safety is higher, the service life can be effectively prolonged, installation efficiency is high, labor intensity is small, the service life of spare parts is prolonged, transmission sound is small, the environment is not polluted, and major accidents caused by transmission falling are avoided. The lock pin piece comprises a pin body composed of two hollow coupling pieces which are oppositely matched, a lock nail is fixed in the pin body through a screw driving method, and the end portion of the lock nail is expanded after being driven, so that the end portion of the hollow coupling piece of the pin body at the end portion is turned outwards to fix the flower type nut to the screw shaft portion of the input shaft or the output shaft. And a series of problems caused by the loosening amount are eliminated.

    本发明运输车辆传动轴总成的技术领域,公开一种风机运输拖车的传动轴固定装置,通过输出轴、输入轴和凸缘一采用贯穿设计并经过花型螺母固定,输出轴、输入轴经过花型螺母在锁销件的作用下与凸缘一进行固定,使得其输出轴和输入轴均能具备大驱动力、大力矩传动,使得其安全性更强,寿命也能得到有效地提高,安装效率高、劳动强度小,延长各备件的使用寿命,传动声音小不污染环境,不会因传动下落发生重大事故。锁销件包括由相对配合的两个空心偶合件组成的销体,销体内部采用螺钉打入法固定有锁钉,经过打入锁钉端部发生膨胀,使得端部的销体的空心偶合件的端部外翻将花型螺母固定在输入轴或输出轴的螺丝轴部分处,消除其松动量带来的一些列问题。
