Description
Technical field
The utility model relates to a kind of face-face friction pair experimental provision of four-ball tester special use, can carry out the secondary test of falseface-face contact friction on four-ball tester, is specially adapted to the experimental study of wear-self-compensation lubricating additive.
Background technology
At present, the core position of known four-ball tester as shown in Figure 3, it be try on one and three under try, four bulb diameters are 12.7mm, material is the GCr15 steel.The rotation of trying on during experiment, it is static to try down, and four balls rub mutually, can only simulate the test of the some contact friction pair of steel-steel.If will simulate the secondary test of the face contact friction of steel-steel or steel-copper, can only on another kind pin dish testing machine, carry out.In the research of wear-self-compensation lubricating additive, four-ball tester is mainly used in the tribology effect of investigating lubricating additive, and can only carry out on another kind pin dish testing machine the investigation of the self-repair effect of lubricating additive.The polishing scratch that rubs of trying because try on the four-ball tester with under three is an arc surface, bring very big difficulty for the contextual analysis of organization in later stage, and pin dish test function addresses this problem well, can obtain the polishing scratch on plane.The wear-self-compensation lubricating additive is difficult in and forms the selfreparing coating on the contact friction pair in addition.This has brought great inconvenience to the researchist, promptly can not satisfy the requirement of carrying out multiple test on same testing machine.And the price of pin dish testing machine is very expensive, and this has brought the difficult problem of fund aspect to the scientific research personnel.
The utility model content
The purpose of this utility model is to overcome the some contact friction pair that the prior art four-ball tester can only be simulated steel-steel, can not simulate the secondary test of face contact friction of steel-steel or steel-copper, and a kind of face-face friction pair experimental provision of four-ball tester special use is provided.This experimental provision can be on four-ball tester light falseface contact friction pair, and can also change the material of test specimen more easily and easily take off or load onto sample from anchor clamps, make the range of application expansion of four-ball tester.
For achieving the above object, design of the present utility model is: upward be provided with a boss below the specimen holder (1), be used for locating sample (4) (seeing accompanying drawing 1).The first half of last specimen holder is a conical structure, links with electric machine main shaft.The downside of last specimen holder is provided with a square pin (2), and this pin is used for locating sample and sample is gone up in drive and electric machine main shaft rotates synchronously.The oil box groove is a planar structure, and the following sample of disc is positioned in the oil box groove, by pressure ring and nut it is locked.The last sample of so just having realized annular has been realized the purpose of falseface contact friction pair on four-ball tester rotating under the drive of motor on following specimen surface.
According to above-mentioned utility model design, the utility model adopts following technical proposals:
A kind of face of four-ball tester special use-face friction pair experimental provision, comprise one and the joining specimen holder of going up of electric machine main shaft, the oil box of sample under arrangement, the fixing pressure ring and a nut that has overhanging handle of sample down, the external thread rotary of described nut lower end internal thread and described oil box is joined, and the upper end internal shoulder is pushed down the upper surface of described pressure ring, it is characterized in that sample is an annular, following sample is a disc, there is the endoporus coupling of boss and last sample described lower end of going up specimen holder, and this boss side surfaces has " L " connected in star coupling on square pin and the last sample; The inner bottom surface of described oil box is plane and following sample coupling.
The utility model compared with prior art, have following conspicuous substantive distinguishing features and advantage: when keeping the original multiple function of four-ball tester, as long as change this experimental provision, just can on four-ball tester, carry out the test of falseface contact friction pair, and this apparatus structure is simple, and it is very convenient that the replacing sample is installed.
