Characteristics of the present invention can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
Description of drawings
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
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, high-precision minitype bearing life tester of the present invention, it comprises the test casing 100 of a sealing, in described test casing 100, be provided with some main shafts 200, the front end of described main shaft 200 is provided with axle sleeve 110, test is installed between described axle sleeve 110 and the main shaft 200 with bearing 10, and the rear end of described main shaft 200 is connected with motor 300, and described motor 300 is arranged on the described test casing 100.
In the present invention, be provided with counterweight 120 in the bottom of described test casing 100; In process of the test, when bearing 10 inefficacies or overload are used in test, play a protective role.
In the present invention, be provided with inductor 130 in the bottom of described test casing 100, described inductor 130 is connected with the alarm display apparatus (not shown), and the induction end of described inductor is pointed to the counterweight 120 of described test casing 100 bottoms.
In the present invention, on described test casing 100, also be connected with calorifier 400; Be used for heating with bearing 10 to the test in the test casing 100 in process of the test, the temperature of calorifier 400 can be different according to the test products specification, and the customer requirement difference can be regulated voluntarily; Described calorifier 400 is connected with alarm display apparatus by a temperature controller.
