The invention relates to an intermediate supporting seat assembly, a transmission shaft assembly and a transmission system. The intermediate supporting seat assembly comprises a supporting seat shell, a transmission shaft and a transmission shaft, the supporting shaft penetrates through the supporting seat shell and is rotatably connected with the supporting seat shell through a bearing, the supporting shaft can move relative to the supporting seat shell in the axial direction, and the bearing moves along with the supporting shaft in the axial direction; the damping mechanism is arranged between the supporting shaft and the supporting seat shell and used for providing damping force when the supporting shaft moves relative to the supporting seat shell in the axial direction. According to the middle supporting seat, the supporting shaft can move relative to the supporting seat shell in the axial direction, when the supporting shaft is subjected to axial force, the supporting shaft moves relative to the supporting seat shell in the axial direction, the bearing moves along with the supporting shaft, impact force is prevented from directly acting on the bearing, the influence of axial impact force on the bearing is reduced, and the failure rate of the middle supporting seat is reduced; in the moving process of the supporting shaft, the damping mechanism generates damping force to dissipate impact energy, and the damping mechanism can play a role in vibration reduction so as to reduce vibration in the running process of the supporting seat assembly.

    本发明涉及一种中间支承座总成、传动轴总成及传动系统,中间支承座总成包括:支承座壳体;支承轴,其穿过支承座壳体,且通过轴承与支承座壳体可转动连接,支承轴可沿轴向相对支承座壳体移动,轴承随支承轴沿轴向移动;阻尼机构,其设于支承轴和支承座壳体之间,用于在支承轴沿轴向相对支承座壳体移动时提供阻尼力。本申请将支承轴设为可沿轴向相对支承座壳体移动,支承轴受到轴向力时,支承轴沿轴向相对支承座壳体移动,轴承随支承轴移动,避免冲击力直接作用在轴承上,降低轴向冲击力对轴承的影响,以降低中间支承座故障率;支承轴在移动过程中阻尼机构产生阻尼力耗散冲击能量,阻尼机构可起到减振的作用,以降低支承座总成运行过程中的振动。
