Problems solved by technology

The previous rotary drum connection structure was relatively complicated, with many parts and complex structure. The drums were connected by setting two ears through fasteners, so the overall size was large and the load during retraction was mainly borne by shearing fasteners and bolts. When installing, consider the cooperation between the drum and the cylinder, and also consider the cooperation between the ears of the drums. The installation process is more complicated and cumbersome.

Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0027] Such as figure 2 As shown, a rotary drum connection structure provided by the present invention includes two semi-circular rotary drums 1 and 2 butted to form a circular connection with the landing gear buffer strut cylinder 100 . It also includes the connecting shaft 3 for connecting the rotating drum 1, the rotating drum 2 and the rocker arm 200, and the fastener 4 for axially fixing the connecting shaft 3 after the connection.

Abstract

The invention provides a rotating cylinder connecting structure. The structure is formed by two semi-ring type rotating cylinders through butt joint; the two ends of the rotating cylinders are provided with connecting holes passing through the axis of the rotating cylinder; the inner diameter on the end side of one connecting hole and the outer diameter on the end side of the other connecting holeare provided with annular grooves, and the profiles of the two annular grooves are in matching with each other; after the butt-jointing of the two rotating cylinders, the annular groove on the end side of the inner diameter is coincident with the annular groove on the end side of the outer diameter; and the two connecting holes at the place are coaxial, and connection shafts used for connecting with rocking arms are arranged in the connecting holes on the two butt-jointed rotating cylinders. Compared with the related art, the structure is small in profile volume, simple in component, light inweight, easy in operation and maintenance and excellent in usage performance.

Description

technical field [0001] The invention relates to the field of aircraft landing gear structure design, in particular to a rotary cylinder connection structure. Background technique [0002] As an important part of aircraft taxiing, take-off and landing, aircraft landing gear itself needs to bear many loads and functions, which will inevitably lead to complex structure and large size of the landing gear. At the same time, the layout space of the landing gear on the aircraft is limited. During the sweeping process of the line movement, the space between the landing gear itself and the nearby oil pipes and cables is small. [0003] Such as figure 1 As shown, the conventional traditional landing gear retracting mechanism generally performs plane flipping and retracting movement around the fixed rotation axis of the outer cylinder of the aircraft landing gear, and the installation and adjustment are connected between the cylinder and the rocker arm through joint bearings or univer...
