Description
Technical field
The present invention relates to wear-resisting test technical fields, refer specifically to a kind of constant-temperature constant-humidity environment abrasion test case, are suitable for packet
Include the quick test of the Parts Materials such as auto parts wear-resisting property under various humiture environment.
Background technology
In automobile glass lifter product structure, the sliding block of bearing automobile glass is made to slide fortune up and down by the constraint of guide rail
It is dynamic, an opposite sliding friction campaign is generated between sliding block and guide rail, is caused sliding block and guide rail that can all generate abrasion, how to be selected most
The finish materials of excellent sliding block material and guide rail are a big difficulties of glass-frame riser product design.Need design a kind of
Rub resistance is tested, and Experimental Comparison is carried out to the material of selection；Implement if abrasion test is arranged on practical car door, can because
The stress that sliding block works in glass-frame riser system is complicated, i.e., the contact of sliding block and guide rail is not constant, examination
The practical wear-resisting property of material cannot be objectively responded by testing result, be unable to get authentic and valid wear-resisting property result；Experiment is used
Motor be that interval uses motor, test period to need frequently rest heat dissipation, the period of experiment is long, and experimentation cost is high；To wear-resisting
Performance can only subjective judgement, it is difficult to carry out an objective wear extent assessment；Choosing to the wear-resisting property assessment and material of material
It is little to select effect.
Under normal circumstances, when carrying out the selection of material, a wear resistance test for being directed to material, proving ring can be designed
The actual working environment of part is simulated in border as possible, to detect the wear-resisting property of two kinds of materials.Abrasion test on the market is set at present
It is standby, it is the shape that two materials are processed into needs mostly：A kind of material is processed into the tablet sheet body part that length is more than 100mm,
Another material is processed into barred body part, and two parts are contacted with each other with the pressure set, a part stationary, another
Part carries out linear reciprocating motion, after having run the period of setting, by wear trace subjective assessment and the front and back weight of test
The comparison of waste carrys out the wear extent (as shown in Fig. 1) of assessment material；The sound generated to friction during experiment is led
Evaluation is seen, a kind of wear-resisting property data of material are ultimately formed.In the existing abrasion test equipment in market, drive part is generally adopted
With screw drive structure, the test body for driving needs to move back and forth, this structure has several drawbacks in that：1, material operation away from
From shorter, can only generally run 100mm or so (if screw rod is long, after stress, flexural deformation is generated in the middle part of screw rod, cannot
Ensure that the pressure in operational process is constant)；2, the speed run is not high, and linear velocity is difficult that cannot meet automobile more than 80mm/s
The speed of service of glass-frame riser：60mm/s~160mm/s；3, the electronic component and motion of some in equipment, it is difficult to resistance to
By the working environment of high temperature and high humidity；The evaluation and comparison of the room temperature wear-resisting property of material are can be only done, high temperature height cannot be carried out
Experiment under wet environment.And the wear-resisting property of many nonmetallic materials, under different temperature, humidity environment, its variation is not
It is linear, so abrasion resistance properties of the needs assessment material under different temperatures section, different humidity environment；4, testpieces
The movement travel of one single only has about 100mm, and most one single motion stroke of automobile glass lifter have 400mm~
550mm, the distance of a single motion need testpieces to move back and forth 4~5 times to can be only achieved；Testpieces during the test can
Abrasion powder is generated, these powder can participate in friction test, and it is short at one that this test method is equivalent to two testpieces
Distance in the accumulative recurring number of forward and reverse friction, have difference, the wear extent and reality of generation with the actual working state of part
Working condition is differentiated.
