Abstract
The utility model provides an oil-carrying bearing life tester, which comprises an adjustable-speed motor and a suspension. An oil-carrying bearing to be tested is arranged in a bearing chamber, an test shaft is arranged in a hole in the oil-carrying bearing to be tested, the two ends of the test shaft are provided with rolling bearings arranged in a bearing block of the suspension; the test shaft is connected with the adjustable-speed motor through a transmission mechanism; the bearing chamber is arranged on a movable pylon provided with a stopping pin; and a tension scale is connected with the upper end of the stopping pin by a steel wire. By changing the bearing chamber and the test shaft according to the oil-carrying bearing to be tested, the simulated condition test of the oil-carrying bearing of different specifications can be performed, so the utilization rate of the tester is improved and the cost of the tester is reduced.
Description
Technical field
The utility model relates to a kind of test bearing device in serviceable life, particularly tests the oiliness bearing device in serviceable life.
Background technology
Conventional at present oiliness bearing test in serviceable life, it all is the exemplar that need be made into oiliness bearing to be measured standard, under the experiment condition of standard, carry out and condition of work difference that it is actual too big, can not test by its actual operating conditions at the oiliness bearing of concrete kind.Patent ZL200420122297.0 provides a kind of multi-functional life experiment machine, can test the life-span of rotational structure spare, can not simulate actual operating conditions and test.
The utility model content
The utility model provides a kind of oiliness bearing life experiment machine, can adjust test condition by its actual applying working condition, accurately tests its serviceable life.
The technical solution of the utility model is: a kind of oiliness bearing life experiment machine, comprise buncher and suspension, oiliness bearing to be measured is installed in the bearing chamber, the experiment axle is housed in the hole of oiliness bearing to be measured, and rolling bearing is equipped with at experiment axle two ends, and rolling bearing is installed and fixed in the bearing seat of suspension, experiment beam warp gear train is connected with buncher, described bearing chamber is installed on the movable hanger, on the movable hanger locking pin is arranged, and spring balance is connected with the stop pin upper end by steel wire.
Described gear train is shaft coupling and belt transmission.
On the described bearing chamber temperature thermocouple is housed.
The utility model is simple and compact for structure, can simulate the oiliness bearing actual operating conditions and carry out life test, and the result is directly accurate.As long as change bearing chamber and experiment axle according to oiliness bearing to be measured, just can carry out the simulated condition test to the oiliness bearing of different size, improve the utilization rate of experimental machine, reduce the cost of tester table.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, suspension 5 of the present utility model is fixed on the support, and the rotation strong points all on the suspension 5 are all selected rolling bearing 7 for use.Oiliness bearing 10 to be measured is installed in the bearing chamber 9, forms stationary fit with bearing chamber 9 endoporus; Experiment axle 8 is installed in the endoporus of oiliness bearing 10 to be measured, and both are for movingly; Ball bearing 7 is equipped with at experiment axle 8 two ends, and rolling bearing is installed in the bearing seat on the suspension 5; Experiment axle 8 is connected with buncher through gear train, and gear train shown in the figure is shaft coupling 4 and belt transmission 6, and is certain, also can be other gearing, as chain drive, gear drive, also can directly be connected with buncher by shaft coupling.Bearing chamber 9 is installed on the movable hanger 1, on the movable hanger 1 locking pin 2 is arranged, and spring balance is connected by the upper end of steel wire with locking pin 2, and spring balance can apply load by movable hanger 1,9 pairs of oiliness bearings 10 to be measured of bearing chamber.The lower end of bearing chamber 9 has the hole, and temperature thermocouple is housed in the hole.
Before the test, the material of actual axle, size are made experiment axle 8 when at first using according to oiliness bearing to be measured, and its two ends and rolling bearing 7 endoporus mating parts are standard size, make bearing chamber 9. according to oiliness bearing installation dimension to be measured again
During test, oiliness bearing 10 to be measured is pressed into bearing chamber 9, forms stationary fit, both can not relatively rotate; Experiment axle 8 passes oiliness bearing 10 endoporus to be measured, forms movingly, and during test, experiment axle 8 rotates in oiliness bearing endoporus to be measured, after rolling bearing 7 is loaded onto at the two ends of experiment axle 8, is installed in the bearing seat on the suspension 5.Load when adjusting tension scale then and reaching oiliness bearing 10 real works to be measured, start buncher, adjusting rotating speed makes the rotating speed of testing axle 8 reach the real work rotating speed of oiliness bearing 10 to be measured, write down temperature and rotation speed change respectively by thermometer on the equipment and tachometer gage, after reaching the stipulated time, measure the actual wear amount of oiliness bearing 10 endoporus, thereby calculate serviceable life.
When oiliness bearing to be measured 10 changes, only need to change experiment axle 8 and bearing chamber 9 with it the size of mating part get final product, widely applicable.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
