The invention discloses a ventilation device for a mechanical device. The ventilation device comprises a connector, a connector assembly and a grating assembly. The grating assembly is assembled in an inner hole of the connector, and the connector assembly is connected with one end of the connector. The grating assembly comprises spacers, spacer bushes, a bolt and a nut, during assembly, the spacers are installed in the bolt, it is guaranteed that planes on the outer circle faces of the spacers are staggered by a certain angle, and the spacer bushes are installed between every two spacers for isolation. Then the nut is used for tightening. The device is simple in structure, the multiple spacers staggered by the certain angle form a labyrinth structure, it is ensured that the device is ventilated and does not leak oil outwards, and the good ventilation effect can be achieved. 本发明公开了一种机械装置用透气装置，包括接头、接头组件及格栅组件。其中格栅组件装配于接头的内孔中，接头组件与接头的一端进行连接。格栅组件包括隔片、隔套、螺栓和螺母，在进行组装时，将隔片装入螺栓，保证隔片外圆面上的平面错开一定角度，并在每两个隔片之间装上隔套进行隔离。然后用
