Description
(1) technical field
The utility model relates to a kind of testing apparatus that is used for bearing.
(2) background technology
At the sealing bearing production industry, special industry standard is arranged, i.e. JB/T 8571-2008; " the rolling bearing seal deep groove ball bearing prevents dust, leaks fat, temperature rise performance test rules "; Leakage of oil fat and temperature rise are had concrete industry regulation, and test condition and method of testings such as the rotating speed of workpiece, dust medium, limit of temperature rise can quantize qualitative analysis to judge during clear and definite test; But this standard and equipment can not fully satisfy client's specific (special) requirements; Like the sealing and the temperature rise performance of the sealing bearing under different rotating speeds, the different external pressure, under the different external agencys, detect the railway grease of customer equipment the inside and whether can go out through the bearing seepage; Or outside mud, water vapor permeable influence the serviceable life of equipment or bearing inside bearing.Existing measuring technology condition medium speed and external pressure are non-adjustable, can't satisfy the checking of client before design phase and volume production.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of sealing bearing simulation test machine of simulating actual use working environment.
The technical scheme that the utility model solves its technical matters is:
A kind of sealing bearing simulation test machine comprises a bearing seat, and described bearing seat is telescopic; The two ends of bearing seat are fixed with the end cap of center drilling respectively; The center of bearing seat wears a rotor, and sealing bearing can be installed in the two ends of described rotor, and the center position of described rotor and end cap is tightly connected through sealing bearing; One end of rotor stretches out sealing bearing and connects an engaged wheel; Described engaged wheel connects driving wheel through belt, and described driving wheel connects the output shaft of the motor of a rotating speed adjustable, is filled with liquid medium in the cavity in the described bearing seat; One side of described bearing seat connects an air pump through pipeline, and described pipeline is provided with a pressure gauge.
As preferably, motor connects a frequency converter.
As improvement, a side of sealing bearing is provided with thermal sensor, and described thermal sensor connects a temperature indicating device.
As preferably, thermal sensor is a thermopair.
As preferably, bearing seat is provided with the valve that is used for the perfusion fluid medium.
The motor of rotating speed adjustable is delivered to the rotor in the bearing seat of sealing shroud cartridge type through driving wheel and engaged wheel; The two ends of rotor are connected with end cap seal through sealing bearing; The inner ring that when rotor rotation, drives bearing rotates; The different liquid medium be can pour in the bearing seat of sealing shroud cartridge type, and the liquid medium in the bearing seat different pressure, i.e. adjustable in pressure applied through air pump.Then sealing bearing has been simulated the working environment of actual use, and whether different liquid medium and adjustable in pressure, rotating speed adjustable have liquid medium to ooze out as long as observe the sealing bearing at the two ends of bearing seat then, have guaranteed the correctness of product design.In addition, contact with bearing outside diameter in a side of sealing bearing and to be provided with thermopair, and connect a temperature indicating device, the synchronization monitoring temperature variation.
The beneficial effect of the utility model is: the utility model carries out testing authentication through the actual working environment that uses of simulation to sealing bearing, guarantees the correctness of product design, satisfies the request for utilization of product.
(4) description of drawings
Fig. 1 is the structural representation of the utility model.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 1; A kind of sealing bearing simulation test machine comprises a bearing seat 11, and bearing seat 11 is a telescoping structure; The two ends of bearing seat are fixed with the end cap 9 of center drilling respectively; The center of bearing seat wears a rotor 5, and the sealing bearing 6 that needs detection can be installed in the two ends of rotor 5, and rotor 5 is tightly connected through sealing bearing 6 with the center position of end cap 9.One end of rotor 5 stretches out sealing bearing and connects an engaged wheel 10, and engaged wheel 10 connects driving wheel 8 through a belt, and driving wheel 8 connects the output shaft of the motor 7 of a rotating speed adjustable, and motor 7 connects a frequency converter 1, regulates rotating speed through frequency converter 1.Be filled with liquid medium 13 in the cavity in bearing seat 11, a side of bearing seat connects an air pump 3 through pipeline, and pipeline is provided with a pressure gauge 2, and pressure gauge test air pump is to the liquid medium applied pressure.In a side of sealing bearing the thermal sensor 12 of one thermopair is set, thermal sensor connects a temperature indicating device 4.Bearing seat is provided with the valve 14 that is used for the perfusion fluid medium.
During concrete operations, overlap the two ends that sealing bearings 6 are installed in rotor 5 to two of needs test, promptly the two ends of rotor are tightly connected through sealing bearing 6 and end cap 9; Open temperature indicating device 4, and in bearing seat, pour into the liquid medium 13 of 70% volume, valve-off 14; Frequency on the frequency converter 1 is set, confirms the rotating speed of motor 7, also can change workpiece rotational frequency through driving wheel with from the diameter of trailing wheel; Behind the starting motor 7; Opening air pump 3 and progressively give the bearing seat internal pressurization, whether have liquid medium ooze out, judge finally whether the sealing of sealing bearing is qualified if observing the end cap two ends.Then sealing bearing has been simulated the working environment of actual use, and whether different liquid medium and adjustable in pressure, rotating speed adjustable have liquid medium to ooze out as long as observe the sealing bearing at the two ends of bearing seat then, have guaranteed the correctness of product design.In addition, contact with bearing outside diameter in a side of sealing bearing and to be provided with thermopair, and connect a temperature indicating device, the synchronization monitoring temperature variation.
