Description

Technical Field

[0001] This utility model belongs to the technical field of bearing protection brackets, and particularly relates to a bearing protection bracket with an anti-deformation and reinforced structure. Background Technology

[0002] In the construction of rolling bearings, the bearing cage plays a crucial role, serving as a fundamental structural component for separating and positioning the rolling elements.

[0003] Traditional bearing cages are mostly one-piece structures made of stamped steel, brass, or engineering plastics. Their main function is to ensure that the rolling elements remain evenly distributed during operation, preventing them from colliding and rubbing against each other, thereby maintaining the basic operating performance of the bearing. However, under high centrifugal force or uneven loads, the cage body, especially its open end, is prone to radial expansion or axial twisting. This deformation can disrupt the even distribution of the rolling elements, and in severe cases, even cause the rolling elements to seize or the cage to break, resulting in overall bearing failure. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution: This utility model provides a bearing protection frame with an anti-deformation and reinforced structure, including: The cage body and the reinforcing assembly are detachably disposed at the two open ends of the cage body; The outer ends of the cage body are provided with outer ribs; The reinforcement assembly includes an inner reinforcement plate and an outer extension. The inner reinforcement plate is inserted into the inner side of the retainer body, and the outer extension is connected and locked to the outer rib on the same side through a plug-in structure.

[0005] As a preferred embodiment of the above technical solution, the inner side of the inner reinforcing plate is further provided with a number of inner support ribs, which are evenly arranged around the inner side.

[0006] As a preferred embodiment of the above technical solution, the plug-in structure includes a plug post and a socket. The plug post is fixedly mounted on the reinforcing component, and the socket is opened on the outer rib at the position corresponding to the plug post. The plug post and the socket are plugged into each other. The plug post is symmetrically provided with mounting grooves, and a stop block and a spring connecting the stop block and the inner wall of the mounting groove are movably arranged in the mounting groove.

[0007] As a preferred embodiment of the above technical solution, the outer extension and the outer rib on the same side are also provided with a number of locking bolts that lock the two together at intervals.

[0008] As a preferred embodiment of the above technical solution, the cage body is provided with a plurality of slots evenly spaced along the circumferential direction.

[0009] The beneficial effects of this utility model are as follows: This invention establishes a dual constraint mechanism of "internal support and external locking" by detachably installing reinforcing components at both open ends of the cage body: the inner reinforcing plate is inserted into the inner side of the cage body, directly providing radial support force to resist the expansion force generated by the internal rolling elements; simultaneously, the locking of the outer extension with the outer rib restricts the radial deformation of the open ends from the outside. This synergistic reinforcement structure improves the overall circumferential stiffness and torsional resistance of the cage. Attached Figure Description

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0012] Example like Figure 1 As shown, Figure 1 The diagram shown is a front view of the bearing protection frame in the embodiment; This device includes: The cage body 10 and the reinforcement component 20 are detachably mounted on the two open ends of the cage body 10.

[0013] The cage body 10 has multiple slots 11 evenly spaced along its circumference.

[0014] The cage body 10 has a plurality of slots 11 evenly spaced along its circumference to accommodate rolling elements (such as steel balls or rollers). The reinforcing components 20 are detachably disposed at the two open ends of the cage body 10 to enhance the structure and prevent deformation.

[0015] like Figure 2 , Figure 3 , Figure 4 As shown, Figure 2 The diagram shown is a cross-sectional view of the bearing protection frame in the embodiment; Figure 3 What is shown is Figure 2 Enlarged schematic diagram of the structure at point A in the diagram; Figure 4 The diagram shown is a side view of the bearing protection frame in the embodiment; Outer ribs 12 are provided around both ends of the outer side of the cage body 10; The reinforcement component 20 includes an inner reinforcement plate 21 and an outer extension 22. The inner reinforcement plate 21 is inserted into the inner side of the cage body 10, and the outer extension 22 is connected and locked to the outer rib 12 on the same side through a plug-in structure 30.

[0016] The outer rib 12 enhances the structural strength of the cage body 10 and provides a crucial docking and locking foundation for the subsequent reinforcement components 20.

[0017] The inner reinforcing plate 21 extends into and is inserted into the cage body 10, serving as a support to resist radial deformation of the cage body 10.

[0018] The outer extension 22 is connected to the inner reinforcing plate 21 and is located on the outside of the cage body 10, corresponding to the outer rib 12 on the same side. The insertion structure 30 realizes the initial alignment and axial positioning of the outer extension 22 and the outer rib 12.

[0019] The inner side of the inner reinforcing plate 21 is also provided with a number of inner support ribs 24, which are evenly arranged around the inner side.

[0020] The inner support ribs 24 are evenly arranged around the inner side of the inner reinforcing plate 21 to form an internal support skeleton, which further enhances the resistance to compression and torsion.

[0021] The outer extension 22 and the outer rib 12 on the same side are also provided with a number of locking bolts 23 that lock the two together.

[0022] After the outer extension 22 and the outer rib 12 are connected, several through holes are provided at intervals at corresponding positions. By passing the locking bolt 23 through these through holes and tightening the nut, the outer extension 22 and the outer rib 12 are further rigidly locked together.

[0023] The bolted connection provides strong axial preload, which firmly fixes the reinforcing component 20 to the cage body 10, so that they can jointly bear the external load.

[0024] like Figure 5 As shown, Figure 5 The diagram shown is a cross-sectional view of the plug-in structure in the embodiment; The plug-in structure 30 includes a plug post 31 and a socket. The plug post 31 is fixedly mounted on the reinforcing component 20. The socket is opened on the outer rib 12 at the position corresponding to the plug post 31. The plug post 31 and the socket are plugged in and engaged. The plug post 31 is symmetrically provided with mounting grooves. A stop block 32 and a spring 33 connecting the stop block 32 and the inner wall of the mounting groove are movably arranged in the mounting groove.

[0025] The insertion post 31 is fixedly mounted on the outer extension 22 of the reinforcing component 20. The insertion hole is opened on the outer rib 12 of the retainer body 10. Its position corresponds completely to the insertion post 31, and its shape matches the insertion post 31, allowing the insertion post 31 to be inserted smoothly.

[0026] The mounting slot has two symmetrical grooves in the radial direction of the insertion post 31. The stop block 32 is movably set in each mounting slot and can slide radially. When inserting, the stop block 32 is pressed into the mounting slot by external force. When the insertion post 31 is fully inserted into the insertion hole, the external force is removed, and the stop block 32 is reset and popped out under the action of the spring 33, and is locked on the outside of the insertion hole to form a mechanical stop.

[0027] Working principle: Installation process of reinforcement component 20: Align the reinforcement component 20 with the end of the cage body 10, apply axial thrust to align the insert 31 with and insert it into the insertion hole on the outer rib 12. During insertion, press the stop block 32 into the retracted mounting groove by external force. After the insert 31 is fully inserted into the insertion hole, remove the external force. The stop block 32 will be reset and popped out under the action of the spring 33, and stuck at the edge of the insertion hole to form a mechanical stop to prevent the reinforcement component from falling off axially. Finally, pass the locking bolts 23 through the corresponding through holes in sequence to firmly lock the outer extension 22 and the outer rib 12 to form a high-strength rigid connection, so that the reinforcement component and the cage body 10 can bear the load together.

[0028] Working condition: When the bearing is running, the cage body 10 is subjected to radial force, centrifugal force and possible impact load of the rolling elements. The inner reinforcing plate 21 and its inner support ribs 24 support the cage body 10 from the inside and resist inward deformation. The bolted connection between the outer ribs 12 and the outer extension 22 constrains from the outside and prevents outward expansion. The synergistic effect of the inner and outer parts effectively suppresses overall deformation, torsion and vibration, ensures smooth operation of the rolling elements and extends the bearing life.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
