The present invention is a kind of frictional wear test device of bearing pin pairing friction pair, it is a kind of being used under the measuring cell warm air condition, the frictional wear test device of typical case's bearing pin pairing friction pair under given compressive load, windup-degree and rate request, relate to design and transformation, belong to the field shaping technique of product the prior art equipment.
Background technology
Axle is a modal syndeton form in aircraft or other plant equipment with axle bush, axle and auricle.Especially special syndeton of some of aircraft and mechanism, as undercarriage etc., owing to be subjected to the influence of airborne vibration, can there be the shift reciprocately under the forceful action and causes the rubbing wear of matching friction pair material between the bearing pin pairing friction pair that axle and axle bush, auricle are formed, become the topmost failure mode of the type structure.This not only can have a strong impact on the functional requirement of structure, even causes the generation of catastrophic failure easily, has caused the hig diligence of airplane design and applying unit.
And present test unit can only satisfy the difficulty requirement of simplification, standardized component, can't Frotteurism and the rubbing wear of analog component in practical work process.
Summary of the invention
The deficiency that the present invention exists at existing apparatus just and design the frictional wear test device that a kind of bearing pin pairing friction pair is provided, this device can the simulated aircraft bearing pin the typical friction and wear behavior of pairing friction pair, the validity and the permanance of the rubbing wear rule of research work load-up condition lower bearing pin, lining, test pairing friction pair material, railway grease or wear-resistant coating.
The objective of the invention is to realize by following measure:
The frictional wear test device of this kind bearing pin pairing friction pair, it is characterized in that: the both sides of base have back up pad, base links to each other with ground by being bolted on the transition bearing, line shaft is inserted on the back up pad of both sides, line shaft and back up pad are rotationally connected, and to form two pairs of pairing friction tests between the front bushing at place and the back bushing secondary, on the line shaft between the base supported on both sides plate, loading auricle of suit by U type clamp, it is secondary to form another pairing friction test between it and the line shaft, line shaft is respectively installed a driven shaft and above-mentioned pairing friction test subcomponent again by rocking arm and connecting rod about it, the upper end of U type anchor clamps connects load transducer, carry the lotus sensor and connect the titanium alloy transmission rod, transmission rod passes bracing frame and fixes with the loading nut.
The invention provides a kind of being used under the measuring cell warm air condition, the frictional wear test device of typical bearing pin pairing friction pair under given compressive load, windup-degree and rate request.And carried out experimental test at 3 kinds of pairings friction pair materials, 2 kinds of lubricant methods, 2 kinds of wear-resistant coatings, experimental study above-mentioned pairing friction pair material under different load and lubricant method wear extent along with the Changing Pattern of wearing-in period and magnitude of load, for the design and select material of this type of syndeton, the selection of lubricant method provide foundation.
