Technical Field

[0001] This utility model relates to the field of motion platform technology, specifically to a bearing seat device for a motion platform. Background Technology

[0002] A motion platform is an interactive device that integrates mechanical, electronic, and software technologies. It creates a realistic dynamic experience by simulating different motion states, such as vibration, tilting, and rotation, and is widely used in entertainment, education, training, and other fields.

[0003] The operation of a motion platform is inseparable from the drive of a motor. Generally, the motor drives a rotating rod to rotate, which in turn drives other mechanisms. Common rotating rods are usually straight rod structures, which may slide on the bearing housing during use, causing the motor to move. After the motor deviates from its original position, it may rub against the support frame and other structures, affecting its service life. In order to fix the position of the motor, prevent the motor from rubbing against other structures, and ensure its service life, we propose a bearing housing device for motion platforms. Utility Model Content

The left side of the sliding limiting sleeve abuts against the right side of the inner ring of the bearing. The second rotating rod is provided with threads, and a threaded limiting sleeve is threadedly connected to the second rotating rod. The left side of the threaded limiting sleeve abuts against the right side of the sliding limiting sleeve. Both the sliding limiting sleeve and the threaded limiting sleeve are threadedly connected with several sets of screws. The second rotating rod is provided with several sets of mounting grooves corresponding to the screws.

[0007] Preferably, the diameter of the first rotating rod is larger than that of the second rotating rod.

[0008] Preferably, both the first rotating rod and the sliding limiting sleeve are rotatably fitted with dustproof plates, and the side of the dustproof plate closest to the bearing frame abuts against the bearing frame.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figure 1-3 This utility model provides a technical solution: a bearing seat device for a dynamic platform, including a reduction gearbox 1, a motor 2 fixedly installed on the top of the reduction gearbox 1, a cylinder 3 fixedly installed on the top of the reduction gearbox 1, a first rotating rod 5 provided on the reduction gearbox 1, a second rotating rod 15 fixedly connected to the right end of the first rotating rod 5, a bearing frame 4 provided on the right side of the reduction gearbox 1, a bearing outer ring 9 rotatably connected to the inner wall of the bearing frame 4, a bearing inner ring 11 provided in the bearing outer ring 9, a plurality of sets of balls 10 provided between the bearing outer ring 9 and the bearing inner ring 11, the right side of the first rotating rod 5 abutting against the left side of the bearing inner ring 11, the second rotating rod 15 slidingly passing through the bearing inner ring 11, and a limiting mechanism for preventing the second rotating rod 15 from shifting is installed on the second rotating rod 15.

[0017] When the motion platform is running, the motor 2 drives the first rotating rod 5 to rotate, which in turn drives the second rotating rod 15 to rotate. Under the action of the first rotating rod 5, the second rotating rod 15 cannot slide to the right. At the same time, under the action of the limiting component, the second rotating rod 15 cannot slide to the left, thereby achieving the positioning of the second rotating rod 15, thus fixing the position of the motor 2, preventing the motor 2 from rubbing against the support frame and other structures, and extending its service life.

[0018] The limiting mechanism includes a sliding limiting sleeve 6, which is slidably sleeved outside the second rotating rod 15. The left side of the sliding limiting sleeve 6 abuts against the right side of the inner ring 11 of the bearing. The second rotating rod 15 is provided with threads, and a threaded limiting sleeve 7 is threadedly connected to the second rotating rod 15. The left side of the threaded limiting sleeve 7 abuts against the right side of the sliding limiting sleeve 6. Both the sliding limiting sleeve 6 and the threaded limiting sleeve 7 are threadedly connected with several sets of screws 8. Several sets of mounting grooves 12 corresponding to the screws 8 are opened on the second rotating rod 15.

[0019] The position of the sliding limit sleeve 6 is fixed by the threaded limit sleeve 7, thereby fixing the position of the second rotating rod 15. The threaded limit sleeve 7 and the sliding limit sleeve 6 are further fixed by the screw 8 to prevent the threaded limit sleeve 7 and the sliding limit sleeve 6 from loosening, thereby restricting the position of the second rotating rod 15 and preventing the second rotating rod 15 from sliding to the left.

[0020] The diameter of the first rotating rod 5 is larger than that of the second rotating rod 15.

[0021] Example 2: Please refer to Figure 4-6 Unlike Embodiment 1 of this application, both the first rotating rod 5 and the sliding limiting sleeve 6 are rotatably fitted with dustproof plates 14. The side of the dustproof plate 14 closest to the bearing frame 4 abuts against the bearing frame 4. The dustproof plate 14 can prevent dust and other impurities from entering the bearing frame 4 and affecting the operation of the device.

[0022] A sealing ring 16 is fixedly connected to the side of the dustproof plate 14 near the bearing frame 4. A sealing groove 17 matching the sealing ring 16 is provided on the bearing frame 4. The sealing ring 16 and the sealing groove 17 are slidably connected to further enhance the sealing performance and ensure the normal operation of the device.

[0023] The bearing housing 4 is equipped with an oil inlet 13, which allows lubricating oil to be added to the bearing housing 4 to extend its service life.

[0024] Working principle: When the motion platform is running, motor 2 drives the first rotating rod 5 to rotate, which in turn drives the second rotating rod 15 to rotate. Under the action of the first rotating rod 5, the second rotating rod 15 cannot slide to the right. At the same time, the position of the sliding limit sleeve 6 is fixed by the threaded limit sleeve 7. The threaded limit sleeve 7 and the sliding limit sleeve 6 are further fixed by the screw 8 to prevent the threaded limit sleeve 7 and the sliding limit sleeve 6 from loosening, thus restricting the position of the second rotating rod 15 and preventing the second rotating rod 15 from sliding to the left. This achieves the positioning of the second rotating rod 15, thereby fixing the position of motor 2, preventing motor 2 from rubbing against the support frame and other structures, and extending its service life.

[0025] Dustproof plates 14 are rotatably fitted around the first rotating rod 5 and the sliding limit sleeve 6. A sealing ring 16 is fixedly connected to the side of the dustproof plate 14 near the bearing frame 4. The dustproof plate 14 and the sealing ring 16 can prevent dust and other impurities from entering the bearing frame 4 and ensure the normal operation of the device.
