Accompanying drawing explanation
Fig. 1 is the front view (partial cross) of the present embodiment.
Fig. 2 is the left view of the present embodiment.
Embodiment
As shown in Figure 1 and Figure 2, the present embodiment is a kind of varying load bearing life proving installation, has base plate 1, this base plate is fixed with motor 2 and bearing fixing device 3, the rotation axis 21 of motor 2 is provided with varying load device, and rotation axis 21 end stretches in bearing fixing device 3.Bearing fixing device 3 is made up of upper semi-ring 31 and lower semi-ring 32, and wherein descend semi-ring 32 to be fixed on base plate 1, upper and lower semi-ring is connected and fixed by screw 33.
In the present embodiment, varying load device comprises joint sleeve 4, connecting rod 5, percussion mechanism 6, supporting sleeve 7 and support 8, wherein joint sleeve 4 is placed on rotation axis 21, connecting rod 5 is vertically arranged, connecting rod lower end is fixed on joint sleeve 4, small end connects percussion mechanism 6, supporting sleeve 7 is placed on connecting rod 5, and supporting sleeve 7 is fixed on base plate 1 through support 8.In this example, percussion mechanism 6 has the eccentric top of eccentric top 61, two that two horizontal symmetrical arrange and is driven by vibration motor.During normal work, two eccentric top 61 move toward one another, offset by the level of centrifugal force, synthesizing longitudinal centrifugal force for rotation axis 21 provides load.
The principle of work of the present embodiment is as follows: be fixed on rotation axis 21 by bearing 9 suit, and be placed between upper semi-ring 31 and lower semi-ring 32 by bearing 9, fix upper and lower semi-ring by screw 33, thus it is fixing to realize bearing location.Motor 2 is with dynamic bearing 9 inner ring to rotate, and varying load device provides load for rotation axis 21, simulates real use state.Detect bearing 9 in real time by temperature sensor, work as Bearing Temperature, illustrate that bearing damages.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in scope of the present utility model, the change made, change add or replace, all should belong to protection domain of the present utility model.
