By mounting the bearing housing 310 on the side of the second mounting plate 120 facing the first mounting plate 110, the stability of the portion of the gear shaft 400 between the first mounting plate 110 and the second mounting plate 120 during rotation can be further enhanced, i.e., the possibility of eccentric displacement of the free end of the gear shaft 400 connected to the rotation shaft of the damper motor 200 can be reduced. Meanwhile, in general, the electric control actuator load testing device 10 is vertically disposed, and the bearing assembly 300 is disposed on the side of the second mounting plate 120 facing the first mounting plate 110, that is, between the second mounting plate 120 and the first mounting plate 110, so that the overall center of gravity of the electric control actuator load testing device 10 can be reduced, and the overall stability of the device during operation can be improved.
Specifically, a first mounting groove 311 that is matched with the shape of the deep groove ball bearing 330 is provided on a side of the bearing block 310 facing the second mounting plate 120, and the bearing block 310 is attached to the second mounting plate 120 on a side facing the second mounting plate 120. When the bearing seat 310 is attached to the second mounting plate 120 toward one side of the second mounting plate 120, the second mounting plate 120 serves to close the first mounting groove 311, the deep groove ball bearing 330 is located in the first mounting groove 311 at the upper limit of the axial direction of the gear shaft 400, and the axial play of the deep groove ball bearing 330 can be adjusted by controlling the depth of the first mounting groove 311, while limiting the axial displacement of the gear shaft 400.
Similarly, a second mounting groove 312 adapted to the shape of the two-layered angular contact bearing 320 is provided on a side of the bearing seat 310 facing away from the second mounting plate 120, and the bearing assembly 300 further includes a bearing cover 340 disposed at an opening of the second mounting groove 312, where the bearing cover 340 is connected to the bearing seat 310 and is used to fix the two-layered angular contact bearing 320 to be layered in the second mounting groove 312. The bearing cover 340 is configured to fix two stacked angular bearings 320 in the second mounting groove 312, and specifically, the bearing cover 340 includes a cover plate 341, one end of the cover plate 341 facing the bearing seat 310 is provided with an annular protrusion 342, and when the cover plate 341 is in fit connection with the bearing seat 310, the annular protrusion 342 abuts against the angular bearing 320.

Referring to fig. 1, in an embodiment, the damper motor 200 is mounted on a side of the first mounting plate 110 opposite to the second mounting plate 120, and a rotation shaft of the damper motor 200 penetrates through the first mounting plate 110. By installing the damping motor 200 on the side of the first mounting plate 110 facing away from the second mounting plate 120, the center of gravity of the whole electric control actuator load testing device 10 can be reduced, and the whole stability of the device during operation can be improved. Meanwhile, when the damping motor 200 is mounted on the side of the first mounting plate 110 opposite to the second mounting plate 120, the rotating shaft of the damping motor 200 needs to penetrate through the first mounting plate 110 and be connected with the gear shaft 400, and the first mounting plate 110 can play a role in fixing the rotating shaft of the damping motor 200, so that the damping motor is prevented from being deviated and swaying.

Because the damping motor 200 is mounted on the side of the first mounting plate 110 facing away from the second mounting plate 120, in order to avoid the electric control actuator load testing device 10 from performing a test, the damping motor 200 is disposed at the lowest position to perform a supporting function, a bottom plate 140 is disposed on the side of the first mounting plate 110 facing away from the second mounting plate 120, and the bottom plate 140 and the first mounting plate 110 are in supporting connection through a lower supporting frame 150, so that the bottom plate 140 is used as a supporting part of the whole device. In order to reduce the influence of vibration generated during the operation of the damping motor 200 on the whole device, the damping motor 200 is disposed at intervals with the bottom plate 140 and the lower support frame 150, that is, the damping motor 200 is not in direct contact with the bottom plate 140 and the lower support frame 150, so that vibration transmitted to the fixing seat 100 by the damping motor 200 can be reduced, and the whole stability of the electric control actuator load testing device 10 is improved.
Further, the lower support frame 150 includes two opposite lower support plates 151, and the damper motor 200 is disposed between the two lower support plates 151; the upper support frame 130 includes two opposite upper support plates 131, and the arrangement direction of the upper support plates 131 is perpendicular to the arrangement direction of the lower support plates 151.

Preferably, in one embodiment, the damper motor 200 is mounted at the center of the first mounting plate 110, and the bearing housing 310 is mounted at the center of the second mounting plate 120. Since the rotation shaft of the damper motor 200, the angular contact bearing 320, the deep groove ball bearing 330 and the gear shaft 400 are coaxially disposed, when the damper motor 200 is mounted at the center of the first mounting plate 110 and the bearing housing 310 is mounted at the center of the second mounting plate 120, the electric control actuator load testing apparatus 10 is easier to maintain an overall balanced state during operation, even if the rotation shaft of the damper motor 200 and the axial center of the gear shaft 400 coincide with the center positions of the first mounting plate 110 and the second mounting plate 120. The center of the second mounting plate 120 and the bearing seat 310 is provided with a through hole through which the gear shaft 400 passes, the center of the first mounting plate 110 is provided with a through hole through which the rotating shaft of the damping motor 200 passes, so that the mounting precision of the gear shaft 400 and the rotating shaft of the damping motor 200 when connected through the coupling 500 is ensured, positioning errors are prevented, and the precision of the test result is ensured.
