The detailed description and obtaining that feature of the present invention can consult the graphic and following better embodiment of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-precision minitype bearing life tester of the present invention;
Fig. 2 is the structural representation of main shaft of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, high-precision minitype bearing life tester of the present invention, it comprises the test casing 100 of a sealing, some main shafts 200 are provided with in described test casing 100, the front end of described main shaft 200 is provided with axle sleeve 110, test bearing 10 is arranged between described axle sleeve 110 and main shaft 200, and the rear end of described main shaft 200 is connected with motor 300, and described motor 300 is arranged on described test casing 100.
In the present invention, the bottom of described test casing 100 is provided with counterweight 120; In process of the test, when test bearing 10 lost efficacy or transshipped, played a protective role.
In the present invention, the bottom of described test casing 100 is provided with inductor 130, described inductor 130 is connected with alarm display apparatus (not shown), and the induction end of described inductor points to the counterweight 120 bottom described test casing 100.
In the present invention, described test casing 100 is also connected with calorifier 400; For heating in process of the test the test bearing 10 in test casing 100, the temperature of calorifier 400 can be different according to test products specification, and customer requirement difference can regulate voluntarily; Described calorifier 400 is connected with alarm display apparatus by a temperature controller.
As shown in Figure 2, described main shaft 200 is fixed in described test casing 100 by solid bearing 210, beating within 2um of main shaft 200.
In the present invention, described main shaft 200 is connected by the driving shaft of belt pulley 220 with described motor 300.
In the present invention, be provided with loading spring 140 between described test bearing 10, carry out axial loading to test bearing 10, heap(ed) capacity depends primarily on the tension force of spring, and the degree of tightness by two fixed screws regulates.
During work, motor 300 drives belt pulley 220 that main shaft 200 is rotated, the inner ring of test bearing 10 rotates together, the outer ring of test bearing 10 is fixed on test casing 100, so the outer ring of chamber body 100 and test bearing 10 is not rotated in process of the test, when the test inefficacy of bearing 10, moment of torsion excessive or stuck time, the outer ring of test casing 100 and test bearing 10 is rotated together, the counterweight 120 fallen like this on test casing 100 will up move, after encountering inductor 130, equipment stops automatically, on alarm display apparatus (not shown), the red light of torque overload lights, and sound the alarm.
Alarm display apparatus (not shown) also has a timer, essential record test period.During equipment manual operation, timer is not-time, and only timer just timing under automatic cycle operating condition, the accuracy of such continuous operation test time is guaranteed.
Automatic cycle is opened, and when after opening of device automatic cycle running button, first calorifier 400 starts running heating, and now motor 300 does not operate, and when waiting the temperature tested in casing 100 to reach set point of temperature, motor 300 automatic cycle opening device normally operates automatically.
In addition, alarm display apparatus (not shown) there is a temperature controller, can test temperature be set, temperature in test casing 100 heats (leaving air temp of calorifier 400 can regulate) by calorifier 400, test casing 100 has a temperature inductor 410, when test the temperature in casing 100 exceed or lower than set point of temperature time, equipment stops automatically, on alarm display apparatus (not shown), temperature overload red light lights, and sounds the alarm.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by appending claims and equivalent thereof.
