Problems solved by technology

In this way, since the actuators for aircraft are driven by aircraft fuel, which has poor lubricity compared with lubricating oil, the sliding surfaces of the actuators are more likely to be worn out than those of general actuators driven by lubricating oil.

Embodiment Construction

[0041] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0042] figure 1 It is a sectional view of the aircraft actuator A (sliding structure) of this embodiment.

[0043] In this aircraft actuator A, a disc-shaped piston 2 (member) and a rod-shaped piston rod 3 (drive shaft) are housed in a hollow cylindrical case 1 (member) in a connected state. The operating oil is injected from the outside into the two spaces K1 and K2 in the housing 1 separated by the piston 2 . The pressure difference of the working oil enables the piston 2 and the piston rod 3 to move left and right along the paper. The housing 1 is formed of aluminum alloy, and the piston 2 and piston rod 3 are integral members formed of stainless steel.

[0044] A bearing 1a and a seal member 1b are provided on the sliding surface (cylindrical surface) between the housing 1 and the piston rod 3, and a bearing 2a is provided on the sliding surface (cylindrical s...

Abstract

In an abrasion resistance reinforcing method of a sliding structure consisting of at least a pair of components in sliding relation and provided with a seal member on the sliding surface of one component, an abrasion resistant metal plated film exhibiting certain reactivity to the material of the seal member is provided on the sliding surface of the other component. An abrasion resistance reinforcing method and a sliding structure ensuring good workability of coating for imparting abrasion resistance and suppressing variation in abrasion resistance can thereby be provided.

Description

technical field [0001] The present invention relates to a wear resistance enhancing method and a sliding structure. [0002] This application claims priority based on Japanese Patent Application No. 2007-276396 filed in Japan on October 24, 2007, the contents of which are incorporated herein by reference. Background technique [0003] Various actuators for aircraft are one type of sliding structure. The actuator for an aircraft is composed of a piston, which is in sliding contact with a cylindrical housing via a bearing, and is connected to a piston rod (drive shaft). As a characteristic, many actuators for aircraft are driven not by dedicated lubricating oil but by aircraft fuel. In the case of an aircraft, since it is required to reduce its own weight as much as possible, the actuator is not driven with special lubricating oil mounted on the aircraft, but the fuel oil that must be mounted on the aircraft is frequently used to drive the actuator. As described above, sinc...
