Engine has a secondary form of a variety of frictions, and lubricating oil, which needs to meet various performances, could meet each friction pair
Lubrication needs.The motion structure form of wherein cam and test block is one of mechanical system structure and engine air distribution system
Basic structure, the working condition between camshaft and rocking arm, tappet affect the air inlet of engine, but in its operation process due to
The variation of rotating speed, temperature, lubricating oil are unable to good lubrication and cause the component wears such as cam, rocking arm, and air distribution system is caused to work
It is inaccurate.It is that will need to test to have simulation test and bench test, bench test in the lubricant effect evaluation of engine lubricating oil
Lubricating oil be added specify model engine carry out field investigation, engine is disassembled after operating, checks each component
The degree of wear evaluates the performance of lubricating oil with this, tests relatively lubricating oil real running environment, but tests the disadvantage is that every
The experiment of a sample needs to carry out engine dismantling and member replacing, and experimentation cost is huge, takes, effort.
There are many current simulation tests, the most commonly used is 4 ball frictional testing machines are used, with the contact shape between ball and ball
Formula measures the lubricant effect of lubricating oil, though test repeatability is preferable, its point-to-point contact form rubs to cam and tappet
It is inaccurate to wipe secondary simulation, test result cannot simulating actual conditions well.In addition to this, also terraced nurse agrees experiment (ring block examination
Test) etc., it all cannot effectively simulate its actual effect.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of camshaft and test blocks
The lubricating oil frictional behaviour tester of form has the advantages that simple in structure, test repeatability is good, at low cost, greatly shortens examination
Test complexity and test period.
In order to achieve the above object, the technical scheme adopted by the utility model is that：
A kind of lubricating oil frictional behaviour tester of camshaft and test block form, including oil sump 15, the lower section of oil sump 15 are set
There are oil drain cock 14, the top of oil sump 15 to be equipped with camshaft 4, the input terminal of camshaft 4 is equipped with second gear 13, second gear
13 are connected by transmission belt 12 and first gear 11, and first gear 11 is mounted on the output shaft of motor 10；Pacify on camshaft 4
