Description

Technical Field

[0001] This invention relates to the field of bearing technology, and in particular to long-life self-aligning roller bearings for vibrating screens in mining machinery. Background Technology

[0002] Mining vibrating screens utilize advanced technologies from both domestic and international sources, including vibrating motor excitation, rubber spring damping, high wear-resistant screen plates, and sealed screen boxes, along with an advanced self-synchronizing vibration principle.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1 to 8 :

[0038] This invention proposes a long-life self-aligning roller bearing for vibrating screens in mining machinery, comprising a bearing mounting component 1, on which a support adjustment component 2 is rotatably mounted; two auxiliary protective components 3 are fixedly mounted on the support adjustment component 2; a self-aligning safety limit component 4 is threadedly connected to the bearing mounting component 1; a bearing dynamic monitoring component 5 is mounted on the bearing mounting component 1; an alarm control component 6 is electrically connected to the bearing dynamic monitoring component 5; and the alarm control component 6 is fixedly mounted on the support adjustment component 2. The bearing mounting component 1 includes: a mounting support outer ring 101, a meshing worm gear ring 102, a support inner ring 103, and auxiliary rollers 104. The meshing worm gear ring 102 is fixedly fitted on the mounting support outer ring 101; a support inner ring 103 is provided inside the mounting support outer ring 101; two auxiliary rollers 104 are rotatably mounted on the outer side of the support inner ring 103, and the two auxiliary rollers 104 are respectively rotatably mounted on the inner ring of the mounting support outer ring 101; and an adjusting threaded post 501 is threadedly connected to the mounting support outer ring 101.

[0039] In this embodiment, the bearing mounting component 1 further includes: a roller bracket 1041, located inside the outer ring 101 of the mounting support; the roller bracket 1041 is located outside the inner ring 103 of the support; two auxiliary rollers 104 are mounted on the roller bracket 1041; the support adjusting component 2 includes: a support adjusting plate 201, mounting auxiliary holes 2011, and a rotating auxiliary sleeve 202; the support adjusting plate 201 has two mounting auxiliary holes 2011; the rotating auxiliary sleeve 202 is fixedly mounted on the support adjusting plate 201; the rotating auxiliary sleeve 202 has a rotating hole; the outer ring 101 of the mounting support is rotatably mounted on the rotating auxiliary sleeve 202; the support adjusting component 2 further includes: a rotating mounting plate 203 and a rotating drive worm gear 204; the rotating mounting plate 203 is fixedly welded to the rotating auxiliary sleeve. On the rotating mounting plate 203, a rotating drive worm gear 204 is rotatably mounted. The rotating drive worm gear 204 is rotatably mounted on the rotating auxiliary sleeve 202. The rotating drive worm gear 204 meshes with the meshing worm wheel ring 102. The rotating drive worm gear 204 is provided with a hexagonal hole. This structure can achieve auxiliary support reversal work through the support adjustment component 2, effectively improving the service life of the bearing, promoting wear balance, and making it more practical. It can effectively assist in the uniform drive switching work on the outside of the mounting support outer ring 101, preventing the pressure from being concentrated at a single point at the bottom of the mounting support outer ring 101 due to long-term use, which would cause deformation and other problems at the mounting support outer ring 101, directly affecting the bearing's operating quality. By adopting a drive rotation structure and regularly replacing the support surface, the wear resistance life of the bearing is improved.

[0040] In this embodiment, the auxiliary protective component 3 includes: an auxiliary protective mounting cover 301, a fixed mounting ring 302, and a rotating sleeve ring 303. The fixed mounting ring 302 is fixedly mounted on the auxiliary protective mounting cover 301. The auxiliary protective mounting cover 301 is fixedly mounted on the rotating auxiliary sleeve 202. The auxiliary protective mounting cover 301 has a corrugated structure. The rotating sleeve ring 303 is rotatably mounted inside the fixed mounting ring 302. The self-aligning safety limiting component 4 includes: a self-aligning limiting mounting plate 401 and an adjusting threaded cylinder 402. The adjusting threaded cylinder 402 is fixedly mounted on the self-aligning limiting mounting plate 401. The adjusting threaded cylinder 402 is threadedly connected to the inner ring 103 of the support. The outer side of the adjusting threaded cylinder 402 is provided with threads. The self-aligning limiting mounting plate 401 is provided with a ring of spherical groove holes. The self-aligning safety limiting component 4 also includes: a positioning ball 403 for positioning. The ball bearing 403 has a ring, and the ring of positioning ball bearings 403 is located outside the outer ring 101 of the mounting support. The positioning ball bearings 403 are rolled and embedded on the positioning ball bearings 403. By using the self-aligning safety limit component 4, the safety limit work can be assisted. In the actual operation of the vibrating screen, it can prevent the self-aligning bearing from going too far in the self-aligning angle, and play an auxiliary limit role. The structure is safer and more practical. The auxiliary protective component 3 can be used to assist in the protection work, effectively preventing sand and gravel from splashing into the bearing and causing the bearing to jam or be damaged. The structure is simple and reasonable, and does not affect the self-aligning torsion work of the bearing. The structure is simple and low cost. By using the rotating adjusting screw cylinder 402, the position of the self-aligning limit mounting plate 401 can be adjusted, that is, the rotation radius when the self-aligning bearing is aligned.

[0041] In Example 2, based on Example 1, the bearing dynamic monitoring component 5 includes: an adjusting threaded column 501, a sliding mounting cylinder 5011, and a connecting spring 502. The adjusting threaded column 501 has a hexagonal hole; the sliding mounting cylinder 5011 is fixedly installed at the bottom of the adjusting threaded column 501; the connecting spring 502 is sleeved inside the sliding mounting cylinder 5011; the bearing dynamic monitoring component 5 also includes: a monitoring sliding plate 503, a pressure sensor 504, and a detection contact 505. The monitoring sliding plate 503 is slidably installed on the sliding mounting cylinder 5011; the connecting spring 502 is connected between the monitoring sliding plate 503 and the inner side of the sliding mounting cylinder 5011; the pressure sensor 504 is fixedly installed at the bottom of the monitoring sliding plate 503; the detection contact 505 is attached to the pressure sensor 504; the detection contact 505 is slidably installed on the sliding mounting cylinder 5011; the bottom of the detection contact 505 has a conical structure; the detection contact 505 is attached to the roller bracket 1041; the alarm control component 6 includes: An alarm controller 601 and an alarm auxiliary light 602 are included. The alarm controller 601 is electrically connected to the alarm auxiliary light 602. The alarm controller 601 is fixedly mounted on the rotating auxiliary sleeve 202. The alarm auxiliary light 602 is fixedly mounted on the rotating auxiliary sleeve 202. The alarm controller 601 is electrically connected to the pressure sensor 504. Through the set bearing dynamic monitoring component 5, a more accurate detection structure can be used to assist in real-time monitoring of the bearing's operating status. The bearing clearance can be indirectly detected by using the detection roller bracket 1041. The detection method is accurate. At the same time, this structure can be adjusted in real time according to the situation. It can adjust and adapt to fit the roller bracket 1041. If a problem is detected, it can assist in real-time alarm prompts. The structure is simpler and more reasonable. When the detection contact 505 is disengaged from the roller bracket 1041, the pressure sensor 504 detects that the pressure has disappeared. At this time, the structure can issue an alarm prompt. The overall structure is simpler and more reasonable.

[0042] The working principle of this embodiment is as follows: First, the rotating drive worm 204 drives the meshing worm gear ring 102, which in turn drives the outer ring 101 of the mounting support to rotate and adjust. The position of the self-aligning limit mounting plate 401 is adjusted by rotating the adjusting threaded cylinder 402, which is the rotation radius when the self-aligning bearing is aligned. The rotating sleeve ring 303 can be fitted onto the shaft for installation and protection. The sliding mounting cylinder 501 can be moved by rotating the adjusting threaded column 501. The detection contact 505 lightly touches the roller bracket 1041. If the bearing wears a lot during use, once the detection contact 505 disengages from the roller bracket 1041, the pressure sensor 504 senses that the pressure has disappeared. At this time, the alarm controller 601 can control the alarm auxiliary light 602 to illuminate and trigger an alarm.
