本发明属于直升机操纵系统结构设计技术领域,具体涉及一种带有防水密封功能的直升机飞行操纵系统传动机构;包括支座(1)、扭轴(2)、摇臂(3)和轴承(6);支座(1)为带法兰的盘形支座;扭轴(2)由密封配合的端盖(7)和扭轴管体(8)组成;摇臂(3)下端端部圆周周向具有盖伞结构的挡水凸缘;摇臂(3)固连在扭轴(2)两端;扭轴(2)穿过支座(1)的通孔并通过轴承(6)连接在支座(1)上,支座(1)固定在机体结构(5)上;支座(1)与摇臂(3)为间隙配合。本发明的传动机构能实现传递操纵指令功能的同时满足防水密封的效果且不会带来额外的摩擦力。

    The invention belongs to the technical field of the structural design of helicopter control systems and relates to a helicopter flight control system transmission mechanism with a waterproof sealing function. The mechanism comprises supports (1), a torsion shaft (2), rocker arms (3) and bearings (6); the supports (1) are disc-shaped supports with flanges; the torsion shaft (2) is composed of an end cover (7) and a torsion shaft pipe body (8) which are matched with each other in a sealed mode; a water retaining flange with an umbrella covering structure is circumferentially arranged at the lower end part of each rocker arm (3); the rocker arms (3) are fixedly connected to two ends of the torsion shaft (2); the torsion shaft (2) penetrates through the through holes of the supports (1) and isconnected to the supports (1) through the bearings (6), and the supports (1) are fixed to a machine body structure (5); and the supports (1) are in clearance fit with the rocker arms (3). According to the transmission mechanism, the function of transmitting a control instruction can be achieved, meanwhile, a waterproof sealing effect is achieved, and no extra friction force is brought.
