Description
Technical field
The utility model belongs to the frictional wear test device field, relates in particular to the frictional wear test device of low load.
Background technology
Friction and wear is one of three kinds of principal modes (wearing and tearing, corrosion and fracture) of material failure, and rubbing wear is to carry out on the surface that is in contact with one another with relative motion, and the material surface and the performance thereof that therefore are in contact with one another are very important to friction and wear behavior.In the friction and wear behavior field of detecting matrix material and surface coating, friction wear testing machine is a kind of common and practical means of testing.
Along with the different development of star moon new material day, the micro-property research of material is most important, wearing quality is to weigh a major criterion of quality of materials, the load range of friction wear testing machine is not less than 50g at present, and for some thin and crisp materials, particularly for the coating of nano thickness and the rubbing characteristics fundamental research of microcosmic material, be easy to cause because load is excessive the even brittle failure of ftractureing of coating or material, cause the accuracy of measurement data not high.
For the load that overcomes friction wear testing machine is higher, be unfavorable for detecting the anti-wear performance of micro nano-coatings, and the rubbing characteristics that is not suitable for researching and analysing the microcosmic material, the rubbing wear of import simultaneously equipment is complicated, expensive.The utility model provides a kind of simple in structure, practical, frictional wear test device that load is low.
The technical scheme that its technical matters that solves the utility model adopts is:
a kind of low load frictional wear test device, it is characterized in that: described low load rubbing wear device comprises casing, motor, gear train drives the objective table that is connected with main shaft, fixture, support, balance stem, base and pressure transducer and friction force sensor, described casing covers motor and gear train, described gear train is comprised of driving gear and follower gear, described driving gear and the engagement of described follower gear, described motor is connected by described follower with objective table, described support lower end is connected with base, described support upper end is connected with the balance stem midpoint, described balance stem one end connects pressure transducer, the other end connects counterweight and connecting rod, described small end connects described balance stem and friction force sensor, fixture under affiliated connecting rod lower end connects, described clutch shaft bearing and the second bearing are fixed on described support upper end, the inner ring of described pin and clutch shaft bearing and the second bearing is fixed, described pin is connected with described balance stem, described support lower end is fixed on described base, described motor is fixed on described base.
As preferred a kind of scheme: described balance stem is that scale mechanism is connected with support, and described driving gear and follower gear are conical gear, and described clutch shaft bearing and the second bearing are deep groove ball bearing.
technical conceive of the present utility model is: with traditional frictional wear test device, compare, we are connected for a day flat structure with support by the design balance bar, pressure transducer equates with the distance of support with distance and the counterweight of support, thereby make the gravity that counterweight has equate with pressure load, adopt counterweight load test pressure, when not adding counterweight, by the rider on the adjustment bar, loading force is made zero, the test loading force changes along with the weight change of counterweight, counterweight can be by weighing-appliance weighings such as analytical balances, counterweight weight can be accurate to 0.0001g, thereby can hang down the load friction and wear test.
The beneficial effects of the utility model are mainly manifested in: simple in structure, can hang down the load friction and wear test.
