Abstract
The invention belongs to the technical field of aviation, and relates to a bi-directional high load-bearing capacity wear-resistant mechanism. The bi-directional high load-bearing capacity wear-resistant mechanism is characterized by adopting a two-sided self-lubricating composite gasket and a deflection rocker arm with a self-lubricating wear-resistant bush to realize a bi-directional high load-bearing capacity wear-resistant function of the mechanism. The bi-directional high load-bearing capacity wear-resistant mechanism has beneficial effects that a simple replaceable structure is arranged between two structures which can slide relative to each other under a high load, and a simple permanent wear-resistant structure is arranged between two structures which slide relative to each other under a secondary high load, so that not only can the self lubrication of the mechanism be realized, but also a replacing mechanism is convenient to maintain and replace, and the slide abrasion problem of an airplane body structure under the high load can be thoroughly solved.
Description
Technical field
The invention belongs to technical field of aerospace, it is related to a kind of two-way high-mechanic wear mechanisms.
Background technology
At present, the common bearing capacity of civilian self-lubricating product is (20～50) mpa, existing aviation self-lubricating knot
It is 100mpa that component maximum bears slip switch power amplifie, and is one side self-lubricating plate-sheet-type structure.At machine control surface suspension arm
Axially be in the relative sliding mode under the conditions of high load all the time in flight course, radial direction bear all the time larger alterable move tired
Labor load, housing construction serious wear in use, and existing motion all can not meet design use requirement.
Content of the invention
The technical problem to be solved in the present invention is: how to design a kind of simple and practical motion, can solve to deflect
During mechanism skimming wear problem, the actual operation requirements of aircaft configuration can be met again.
The technical scheme is that using a kind of two-way high-mechanic wear mechanisms it is characterised in that described one kind is two-way
High-mechanic wear mechanisms are made up of suspension arm, deflection support arm and two-sided self-lubricating Composition spacer；Suspension arm, deflection support arm and
Two-sided self-lubricating Composition spacer is combined by bolt, nuts and washers, and deflection rocking arm can deflect around bolt and bear machine
The radial and axial load of structure；Wherein suspension arm two end axles in the hole press-fits band convex shoulder steel sleeve, and bushing convex shoulder is in suspension arm
Side is to intermediate shaft hole press-fits steel sleeve；Self-lubricating abrasion-resistant bushing is press-fited, achievable mechanism radial direction subtracts in deflection support arm shaft hole
Mill lubricating function, bushing convex shoulder is in deflection support arm lateral direction；Two-sided self-lubricating Composition spacer is arranged on mechanism's high load slip mill
Damage position and axially load outside the deflection support arm that direction is arranged between suspension arm and deflection support arm, achievable mechanism
Axial anti-attrition lubricating function.
The invention has the beneficial effects as follows: slip relatively is had under high load by a kind of simply replaceable structural arrangement
Between structure, it is placed under second highest load by a kind of simply permanent abrasion-proof structure and has between the structure relatively slided, both
The self-lubricating of achievable mechanism, is easy to replace maintenance and the replacing of mechanism again.Compared with existing motion, there is carrying energy
Power high (can at high loads continuous firing) and the features such as working service facilitates, can in the given usage cycles of replaceable structure
To ensure that housing construction uses safety, thoroughly solve the problems, such as skimming wear under high load for the aircraft body structure, have larger
Actual application value.
