Description

Technical Field

[0001] The utility model relates to the technical field of bearings, and in particular to an impact-resistant bearing. Background Art

[0002] As a crucial component in modern mechanical equipment, bearings play a crucial role. Their core function lies in providing strong support for rotating bodies. During mechanical operation, the smooth rotation of rotating bodies depends on bearings. Bearings effectively reduce the friction generated by rotating bodies during motion, making mechanical movement more efficient and smoother. At the same time, bearings also bear the heavy responsibility of ensuring the rotational accuracy of rotating bodies. Like a precise guardian, bearings ensure that rotating bodies maintain a high degree of precision throughout their rotation, thus laying a solid foundation for the stable operation of the entire mechanical equipment.

[0003] However, in the actual application scenarios of existing mechanical equipment, bearings have a more obvious defect, that is, their insufficient impact resistance. When the shaft installed on the bearing is subjected to external impact, such as in the operation of some heavy machinery, the shaft may be subjected to impact due to sudden collision, severe vibration or overload, and this impact force will be transmitted to the bearing connected to it without any buffering. Since the bearing itself lacks sufficient impact-resistant structure and performance, after frequently being attacked by such impact forces, it is very easy for the structure to be deformed, worn or even cracked, which will have a serious negative impact on the normal operation of the entire mechanical equipment, and may lead to a series of chain reactions such as frequent equipment failures, a significant increase in maintenance costs and a sharp drop in production efficiency.

[0033] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1 to 4 As shown, this embodiment proposes an impact-resistant bearing, including: an inner ring 1, an outer ring 2, a rotating shaft 3, a longitudinal buffer mechanism and a transverse buffer mechanism. The outer ring 2 is sleeved on the outer periphery of the inner ring 1, and a plurality of rotating shafts 3 are provided. The plurality of rotating shafts 3 are all rotatably connected to the circumferential surface of the inner ring 1, and the circumferential surfaces of the plurality of rotating shafts 3 are in contact with the inner wall of the outer ring 2. Through the cooperation between the inner ring 1, the outer ring 2, the rotating shaft 3, the longitudinal buffer mechanism and the transverse buffer mechanism, it is convenient to support and buffer the transverse impact force and the longitudinal impact force exerted on the bearing, which can effectively prevent the impact force from directly acting on the bearing and reduce the damage to the bearing.

[0035] Among them, the longitudinal buffer mechanism is arranged on the inner ring 1, which is used to buffer the longitudinal impact force. The longitudinal buffer mechanism includes: a fixed rod 4, a support spring 5, a fixed block 6 and a rotating bead 7. There are multiple fixed rods 4, and multiple fixed rods 4 are rotatably connected to the circumferential surface of the inner ring 1. Multiple rotating shafts 3 are respectively rotatably connected to multiple fixed rods 4. Multiple fixed rods 4 are each sleeved with two support springs 5. Both ends of multiple fixed rods 4 are fixedly connected with fixed blocks 6. The fixed blocks 6 are provided with a rotating groove. The rotating bead 7 is rotatably connected in the rotating groove. The rotating bead 7 contacts the inner wall of the outer ring 2. Specifically, when the shaft installed in the inner ring 1 is subjected to a longitudinal impact force, the inner circle is supported in the outer ring 2 by the support spring 5 sleeved on the fixed rod 4, thereby buffering the longitudinal impact force. When the inner ring 1 rotates, it drives multiple fixed rods 4 to rotate synchronously with the inner ring 1. The rotating bead 7 contacts the inner wall of the outer ring 2 and rotates in the fixed block 6, thereby ensuring the smooth rotation of the inner ring 1.

[0036] Among them, the transverse buffer mechanism is arranged on the outer ring 2, which is used to buffer the transverse impact force. The transverse buffer mechanism includes: a fixing ring 8, a connecting spring 9, a support ring 10 and a fixing assembly. The fixing ring 8 is sleeved on the circumferential surface of the outer ring 2. There are multiple connecting springs 9. One end of the multiple connecting springs 9 is fixedly connected to the circumferential surface of the fixing ring 8. The support ring 10 is arranged on the periphery of the fixing ring 8. The other ends of the multiple connecting springs 9 are fixedly connected to the circumferential surface of the support ring 10. There are two fixing assemblies, both of which are arranged on the support ring 10 to fix the fixing ring 8. The support and fixing components include: a driving screw 11 and a fixing plate 12. The two fixing plates 12 are both arranged in an arc shape. The other end of the driving screw 11 is fixedly connected to a hexagonal block 13. A screw hole is opened on the support ring 10. The driving screw 11 is threadedly connected in the screw hole. The fixing plate 12 is rotatably connected to one end of the driving screw 11. The other side of the fixing plate 12 contacts the circumferential surface of the fixing ring 8. Specifically, when the shaft installed in the inner ring 1 is subjected to a lateral impact force, support and buffering are performed by the connecting spring 9 between the fixing ring 8 and the support ring 10, thereby buffering the lateral impact force.

[0037] In this embodiment, when the inner ring 1 of the bearing rotates, it drives multiple fixed rods 4 to rotate synchronously with the inner ring 1. The rotating shaft 3 rotatably connected to the fixed rod 4 rolls between the inner ring 1 and the outer ring 2, contacts the inner wall of the outer ring 2 through the rotating beads 7, and rotates in the fixed block 6, thereby ensuring smooth rotation of the inner ring 1. When the bearing is subjected to a lateral impact force, the connecting spring 9 between the fixed ring 8 and the support ring 10 provides support and buffering, thereby buffering the lateral impact force. When the shaft installed in the inner ring 1 is subjected to a longitudinal impact force, the support spring 5 sleeved on the fixed rod 4 supports the inner circle in the outer ring 2, thereby buffering the longitudinal impact force. When the bearing needs to be fixed to prevent it from swinging, the operator rotates the hexagonal block 13 to drive the drive screw 11 to rotate, thereby driving the fixed plate 12 to clamp the fixed ring 8, thereby preventing the bearing from swinging.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
