Abstract

A fretting wear testing device for an aviation control steel wire rope adopts the structure that a pre-tightening force counterweight and a guiding wheel are used for providing a certain pre-tightening force for the steel wire rope; the other end of the steel wire rope is connected to a fixing support; a wear testing element is fixed by a mounting frame to adjust the distance and an angle between the testing element and the steel wire rope; a variable frequency motor is used for driving an eccentric wheel to rotate, and driving the steel wire rope which is in contact with a vertical support plate to periodically move up and down through the vertical support plate, so as to drive the steel wire rope to periodically swing up and down; when the amplitude of swing of the steel wire rope exceeds a set value, the steel wire rope and the wear testing element are in contact with each other and generate a relative slide with smaller displacement, so that a fretting wear condition of the steel wire rope and a guiding baffle or a pulley can be well simulated in the practical flying process of an airplane.

Description

Wire rope fretting wear test unit for a kind of aviation operation
Technical field
The utility model relates to a kind of wire rope fretting wear test unit, particularly relates to a kind of aviation operation wire rope fretting wear test unit.
Background technology
Wing flap, aileron, tailplane and the vertical tail of general-purpose aircraft generally all adopts cable wire to carry out aerofoil control, and the chief component that aerofoil is handled cable wire is wire rope and chuck.The important component part of handling cable wire as aerofoil, wire rope bears the pretightning force of certain load capacity all the time, and passes through the mobile control realizing aerofoil of the loop system of its composition.
When general-purpose aircraft aloft flies, be typical multiaxial loading state, the wire rope that aerofoil is handled, often in horizontal vibrational state, in the time that wire rope amplitude of fluctuation is excessive, produces fretting wear with the deflector apron contacting or leading block.If the aerofoil of aircraft is handled the stress with wire rope when simulated flight state effectively, set up wire rope fretting wear life appraisal procedure, for the dependability that improves aviation operation wire rope, tool is of great significance.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of aviation operation wire rope fretting wear test unit is provided, and the aerofoil manipulating wire rope that described test unit can reflect general-purpose aircraft is preferably in the time of actual flight state and the stress of deflector apron or pulley.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
Wire rope fretting wear test unit for a kind of aviation operation, it comprises pretightning force counterweight, angle sheave, mounting bracket, wear test part, variable-frequency motor, eccentric wheel, vertical support plate and fixed support, wire rope one end is connected with pretightning force counterweight through angle sheave, the other end is connected on fixed support, wear test part is arranged on mounting bracket, apart from the wire rope certain distance under stationary state, variable-frequency motor output terminal is connected with eccentric wheel, described eccentric wheel is connected with vertical support plate, drive eccentric wheel to rotate by variable-frequency motor, drive vertical support plate to move up and down, and the wire rope that drives its contact produces periodic upper and lower displacement.Thereby excite wire rope periodically to swing up and down.In the time that the amplitude of fluctuation of wire rope exceedes certain value, wire rope and wear test part contact and produce the relative sliding of less displacement.
The top of vertical support plate is provided with counter probe.
The distance of wear test part and wire rope and angle are all adjustable.
The counter probe of the top of vertical support plate can record the number of times that wire rope swings up and down herein.
The beneficial effects of the utility model are: the utility model is wire rope fretting wear test unit for a kind of aviation operation, drive eccentric wheel to rotate by variable-frequency motor, drive the wire rope being in contact with it periodically to move up and down by vertical support plate again, thereby excite wire rope periodically to swing up and down.When the amplitude of fluctuation of wire rope exceedes a timing, wire rope contacts with wear test part and produces the relative sliding of less displacement, mounting bracket is distance and the angle of adjustable testpieces and wire rope also, the motion state can simulate aircraft practical flight time between wire rope and deflector apron or pulley.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of aviation operation of the utility model wire rope fretting wear test unit;
Reference numeral:
1, pretightning force counterweight, 2, angle sheave, 3, wire rope, 4, mounting bracket, 5, wear test part, 6, variable-frequency motor, 7, eccentric wheel, 8, counter, 9, vertical support plate, 10, fixed support.
Embodiment
Referring to Fig. 1, wire rope fretting wear test unit for a kind of aviation operation, comprise pretightning force counterweight 1 and angle sheave 2, the pretightning force counterweight 1 being connected with wire rope 3 provides pretightning force suitable in actual use procedure, and other one end of wire rope 3 is connected to fixed support 10.Wear test part 5 is fixing by mounting bracket 4, and apart from wire rope 3 certain distances under stationary state, testpieces 5 is all adjustable with distance and the angle of wire rope 3.Drive eccentric wheel 7 to rotate by variable-frequency motor 6, drive vertical support plate 9 to move up and down, and drive the wire rope 3 of its contact to produce periodic upper and lower displacement, thereby excite wire rope 3 periodically to swing up and down.In the time that the amplitude of fluctuation of wire rope 3 exceedes certain value, wire rope 3 and wear test part 5 contact and produce the relative sliding of less displacement.
The counter probe 8 of the top of vertical support plate can record the number of times that wire rope swings up and down herein.
Mounting bracket 4 is distance and the relative angle of adjustable wear test part 5 and wire rope 3 also, for the fretting wear situation of wire rope and deflector apron or the pulley of diverse location.
The principle of work of the utility model test unit is:
With vertical support plate 9, the periodic rotary of variable-frequency motor 6 is converted to swinging up and down of wire rope 3 by eccentric wheel 7, wire rope 3 and wear test part 5 contact and produce the relative sliding of less displacement, the motion state can simulate aircraft practical flight time between manipulating wire rope and deflector apron or pulley.
