The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
In figure, test specimen 1, inertial flywheel 2, pitcher pump 3, torsional angle measurement mechanism 4, pitcher pump oil drain switch 5, step-up gear 6, pitcher pump handle 7, torque sensor 8, spring coupling 9, counterweight trimming hand wheel 10, counter weight device 11, one-level lever 12, second lever 13, load sensor 14, self-locking type hydraulic lifting jack 15, the horizontal pointer 16 of lever, reductor 17, test tool 18, counterweight suspender 19, abrasion amount measuring device 20, mainframe 21, counterweight 22, counterweight carriage 23, connecting rod 24, Timing Belt 25, variable-frequency motor 26, crank disc 27, rocker arm 28.
Embodiment
Oscillating bearing is in the situation that apply constant radial load, the oscillating bearing inner ring is swung by certain angle with respect to outer ring, measure the friction factor of self-lubricating knuckle bearing by measuring moment of torsion and radial load, by measure outer ring radially the displacement of the direction of load measure the wear extent of oscillating bearing self-lubricating liner.
At first the test pendulum angle of selecting self-lubricating knuckle bearing exemplar 1 to require.Because the crank and rocker mechanism without quickreturn characteristics that the utility model adopts, so pendulum angle is while adjusting, and the length of crank and rocking bar all needs to adjust.The method that the utility model adopts is crank and rocking bar length on demand, at crank disc, with punching on rocker arm, is connected the adjustment that connecting rod is realized angle.Next self-lubricating knuckle bearing exemplar 1 is contained in test tool, the bottom with the self-locking lifting jack on test tool top is connected, the coupling shaft of test tool side is connected with elastic coupling.Pass through lever counterweight and counterweight trimming hand wheel before loading by one-level lever and second lever level-off, add the zero clearing of counterweight preload sensor registration, choose suitable counterweight by the test load of oscillating bearing exemplar 1, one one is added on the counterweight hitch, often add a counterweight, second lever can be obviously downward-sloping, now lock the locking switch of pitcher pump, press the handle of pitcher pump, until horizontal pointer is aimed at zero graduation, until fill it up with the load needed, the radial load now shown in computer software and the nominal value of counterweight are in the error allowed band, completing radial force loads.Establish hunting frequency, number of oscillations, data acquisition interval on computer software, can start test, variable-frequency electric in process of the test, variable-frequency motor drives reductor input end High Rotation Speed to drive the crank rotation by Timing Belt, thereby makes the rocking bar reciprocally swinging.The input end of reductor is added with inertial flywheel, and the crank disc of output terminal also is equivalent to an inertial flywheel, and the impact to reductor in operational process is less, saves the energy consumption of variable-frequency motor simultaneously.Generally be not more than during the large load of crank and rocker mechanism rocking bar pendulum angle of standard in addition ± 45 °; the utility model increases step-up gear at the rocking bar output terminal; can realize large angle pendulum; in the present embodiment pendulum angle can reach ± 80 °, test can auto stop after reaching the test number (TN) of regulation.While needing to lay down radial load after off-test, the oil drain switch of pitcher pump is slowly opened, second lever is downward-sloping, and counterweight drops on the counterweight carriage, and while preventing from unloading counterweight, the unexpected perk of second lever, impact.
