The oil box that holds in the present invention is a kind of inverted trapezoidal structure, such structure can guarantee oil storage and the smooth-going outflow of fluid, hold on the body that oil box need to be fixed on frictional testing machine, can be fixed with hook holding oil box one sidewall outer surface, hang on friction wear testing machine.The oil guide pipe that holds the connection of oil box bottom is a kind of metallic hose, and metallic hose can change flexible pipe shape can also keep shape after distortion, guarantees that oil nozzle extend in the oil through of specimen holder.
Owing to will simulating multiple real lubricating status, so need to control the fluid flow of oil nozzle, fluid is to rely on self gravitation to stay, so oil nozzle inside is provided with flow control device, a kind of form of described flow control device be close together two with logical baffle arrangement, described oil nozzle inside is a kind of baffle plate with semi-circular through hole with through hole baffle plate, being close to also rotatable baffle plate with described fixed dam is also the baffle plate with semi-circular through hole, by rotating rotatable baffle plate, just can adjust the circulation caliber size of fluid in oil nozzle like this, thereby adjustment flow velocity.
Closed box two other port except oil pipe through temperature transducer and thermosensor, carries out the detection of laboratory data respectively in real time.
Beneficial effect
The lubricating fitting of a kind of friction wear testing machine of the present invention can be in frictional wear experiment process the true lubricating status of analog mechanical equipment, the data that detect are reality more, more accurate.
The lubricating fitting of a kind of friction wear testing machine of the present invention only can be realized immersion oil, oil dripping and three kinds of Different Lubrication Conditions Used of oil spout, strong adaptability in same set of equipment.
The lubricating fitting of a kind of friction wear testing machine of the present invention can also reclaim the lubricating oil of outflow, prevents splashing of fluid in experimentation, has realized reusing of Lubricants.

Embodiment
Below in conjunction with specific embodiments and the drawings, further set forth the present invention.
The present invention relates to a kind of lubricating fitting of friction wear testing machine, comprise closed box 4, hold oil box 1, oil box 3 and oil guide pipe 2;
Hold oil box 1 for a kind of uncovered box body, holding oil box 1 is fixed on friction wear testing machine by fixing device, described oil box 1 bottom of holding has through hole and is connected with oil guide pipe 2, the end of described oil guide pipe 2 is provided with oil nozzle, described oil nozzle inside is provided with flow control device, described oil guide pipe 2 extend into closed box 4 inside by the through hole on closed box body wall 4, the interior friction style of described closed box 4 fixture oil leakaging port below is provided with oil box, described closed box 4 is a kind of upper and lower end-cover-free casing, the arbitrary side of closed box 4 has chamber door, described closed box 4 sidewalls also have two through holes except oil guide pipe 2 through holes, as Fig. 1, 2, shown in 3.
The oil box 1 that holds in the present invention is a kind of inverted trapezoidal structure, such structure can guarantee oil storage and the smooth-going outflow of fluid, hold on the body that oil box 1 need to be fixed on frictional testing machine, can be fixed with hook holding oil box 1 one sidewall outer surfaces, hang on friction wear testing machine.The oil guide pipe 2 that holds oil box 1 bottom connection is a kind of metallic hose, and metallic hose can change flexible pipe shape can also keep shape after distortion, guarantees that oil nozzle extend in the oil through of specimen holder.
Owing to will simulating multiple real lubricating status, so need to control the fluid flow of oil nozzle, fluid is originally to rely on self gravitation to flow down, so oil nozzle inside is provided with flow control device, a kind of form of described flow control device be close together two with logical baffle arrangement, described oil nozzle inside is a kind of baffle plate with semi-circular through hole with through hole baffle plate, being close to also rotatable baffle plate with described fixed dam is also the baffle plate with semi-circular through hole, by rotating rotatable baffle plate, just can adjust the circulation caliber size of fluid in oil nozzle like this, thereby adjustment flow velocity, as shown in Figure 4.
Closed box two other port except oil pipe through temperature transducer and thermosensor, carries out the detection of laboratory data respectively in real time.
Between the upper specimen holder 5 of frictional testing machine and lower specimen holder 6, accompany friction sample, the oil nozzle of oil guide pipe 2 enters in the opening of the semiclosed gear oil box 7 of the rear insertion of closed box 4, lubricating oil is through the inner surface that flows into friction sample of upper specimen holder 5, realize the truth simulation of continuous lubrication, fluid flow in oil box 3 finally by the oil leakaging port of lower specimen holder 6.
The casing that closed box 4 in described lubricating fitting is a kind of upper and lower uncovered, be easily installed in like this on the Laboratory Furniture of friction wear testing machine, the sample that rubs up and down can directly extend into closed box 4 inside, if need to carry out immersion oil friction-wear test, only need to, by inserting the through hole sealing of oil guide pipe 2, then will in closed box 4, add lubricant oil.
When the lubricating fitting of friction wear testing machine of the present invention is placed on friction wear testing machine platform, the upper and lower surface of closed box 4 contacts with the body of friction wear testing machine, so friction style is to carry out frictional wear experiment under sealing condition.
In sum, every have the oil box of holding 1 fuel feeding through oil guide pipe 2, to enter that closed box 4 is interior to be lubricated friction wear testing machine, and the lubricating fitting that finally carries out fluid recovery by oil box 3 is all within protection scope of the present invention.
