Description
Technical field
The utility model relates to wear-resisting test technical fields, refer specifically to a kind of constant-temperature constant-humidity environment abrasion test case, are applicable in
In the quick test of Parts Materials wear-resisting property under various temperature and humidity environment such as including auto parts.
Background technique
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.It needs to design one kind
Rub resistance test carries out Experimental Comparison 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 be it is complicated, i.e., the contact pressure 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；Test is used
Motor be interval using motor, the test period needs frequently rest heat dissipation, and the period of test is long, and experimentation cost is high；To wear-resisting
Performance can only subjective judgement, it is difficult to carry out an objective abrasion loss 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, the wear resistance test for being directed to material, proving ring can be designed
The actual working environment of part is simulated in border as far 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 plate sheet body part that length is greater 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 test front and back weight
The comparison of waste carrys out the abrasion loss (as shown in Fig. 1) of assessment material；The sound that friction generates is carried out during test
Subjective assessment ultimately forms a kind of wear-resisting property data of material.In the existing abrasion test equipment in market, drive part is general
Using screw drive structure, for driving the test body for needing to move back and forth, this structure is had several drawbacks in that：1, material is run
Distance is shorter, can only generally run 100mm or so and (if screw rod is too long, after stress, bending deformation be generated in the middle part of screw rod, no
It can guarantee that the pressure in operational process is constant)；2, the speed run is not high, and linear velocity is difficult not to be able to satisfy vapour more than 80mm/s
The speed of service of vehicle glass-frame riser：60mm/s~160mm/s；3, some electronic component and movement mechanism in equipment, it is difficult to
It is resistant to the working environment of high temperature and high humidity；The evaluation and comparison that can be only done the room temperature wear-resisting property of material, not can be carried out high temperature
Test under high humidity environment.And the wear-resisting property of many nonmetallic materials, under different temperature, humidity environment, its variation
Be not it is linear, so abrasion resistance properties of the needs assessment material under different temperatures section, different humidity environment；4, it tests
The movement travel of one single of part only has about 100mm, and most one single motion stroke of automobile glass lifter have 400mm~
550mm, the distance of a single motion, which needs testpieces to move back and forth 4~5 times, 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 abrasion loss and reality of generation with the actual working state of part
Working condition is differentiated.
