Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, and in particular relates to a deep groove ball bearing ring with a retaining groove. Background Technology

[0002] Bearings are crucial basic components in mechanical systems that support rotational motion, and there are many types. Common bearings generally consist of an outer ring, an inner ring, rolling elements, and a cage. The outer and inner rings have raceways to accommodate the rolling elements, while the cage separates and guides the rolling elements. Deep groove ball bearings, as a type of bearing with spherical rolling elements, rely on the grooves on the outer and inner rings to form raceways. They can simultaneously withstand radial and axial loads and have the advantages of simple structure and wide application.

[0003] However, such bearings still have certain limitations in terms of installation and positioning: in applications that require frequent disassembly or adjustment, the disassembly and assembly process of the existing structure is inconvenient, the operation efficiency is low, and it is difficult to adapt to the needs of flexible installation and dynamic adjustment. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a deep groove ball bearing ring with a retaining groove. By integrating a retractable and lockable locking mechanism in the retaining groove, the applicability and ease of operation of the bearing in occasions that require frequent installation, disassembly or adjustment are improved.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A deep groove ball bearing race with a retaining groove includes an outer race. The outer surface of the outer race has a retaining groove, and a retaining block and an elastic element are provided in the retaining groove. The retaining block is radially retractable through the elastic element. The retaining block has a retracted position in the retaining groove and an outwardly extended working position. The retaining block has at least two locking parts arranged radially along the elastic element. Fasteners are correspondingly provided on the outer race. When the retaining block is in the working position under the action of the elastic element, the fasteners can cooperate with the locking parts at the corresponding positions to limit the radial retraction of the retaining block. When the retaining block is fixed in the retracted position, the fasteners can cooperate with the locking parts at another corresponding position to fix the retaining block.

[0006] Furthermore, the locking block is provided with an anti-detachment part, and the inner wall of the stop groove is provided with a guide part. The anti-detachment part is embedded in the guide part to prevent the locking block from falling off.

[0007] Furthermore, the guide part is a guide groove provided on the side wall of the stop groove, and the anti-detachment part is a protrusion adapted to the guide groove.

[0008] Furthermore, the elastic element is a spring, and the bottom of the stop groove is provided with a mounting hole for accommodating the spring.

[0009] Furthermore, a limiting post is fixedly installed inside the mounting hole, a spring is sleeved on the outside of the limiting post, and a guide cavity is opened at the bottom of the block to slide with the limiting post.

[0010] Furthermore, the end face of the block furthest from the spring is designed as an arc surface.

[0011] Furthermore, the locking part is a through hole provided on the card block, the fastener is a bolt, the outer ring is provided with a threaded hole that mates with the bolt, the bolt is threadedly connected to the threaded hole, and its end can be inserted into any through hole to fix the card block in the corresponding position.

[0012] Furthermore, the through hole includes a working locking hole and a receiving locking hole. When the bolt passes through the working locking hole and is tightened with the threaded hole, the locking block is locked in the working position. When the bolt passes through the receiving locking hole and is tightened with the threaded hole, the locking block is locked in the receiving position.

[0013] Furthermore, the threaded hole is a countersunk hole, so that when the bolt is tightened, its head is flush with the outer surface of the outer ring.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: 1. In this utility model, when the locking block is locked in the working position, its protruding part can serve as a reliable axial positioning surface, cooperate with the external stop to prevent the bearing from moving. Alternatively, the locking block can be locked in the storage position so that it is completely submerged in the stop groove. The outer surface of the outer ring remains intact and smooth, without interference, thus improving the adaptability and operational flexibility of the bearing in different application scenarios. 2. In this utility model, the elastic element provides the power for the automatic pop-out of the locking block, and the locking block is mechanically locked in any desired position by the bolt and the locking holes at different positions. This locking method has a simple structure, is easy to operate and has a reliable connection, ensuring that the locking block will not retract accidentally in the working state and will not pop out accidentally in the storage state. 3. In this utility model, a sliding guide mechanism consisting of a guide part and an anti-detachment part is provided, which significantly improves the stability and reliability of the movement of the locking block.

Detailed Implementation

[0017] like Figures 1 to 3 As shown, the deep groove ball bearing race with a retaining groove 2 of this utility model includes an outer race 1, the outer surface of which is machined with an annular retaining groove 2. Several sets of independently operable telescopic locking mechanisms are evenly arranged along the circumference inside the retaining groove 2. In this embodiment, eight sets are used as an example for explanation.

[0018] Each locking mechanism includes a locking block 3 and an elastic element 4 that provides elastic force to the locking block 3. The locking block 3 can move out of the stop groove 2 under the push of the elastic element 4 and extend to the working position. It can also overcome the elastic force under external pressure and completely retract into the storage position in the stop groove 2.

[0019] To stably fix the locking block 3 in the above two positions, at least two through holes 16 are provided on the body of the locking block 3 along its extension direction as locking parts 5. In this embodiment, two through holes 16 are provided, which are defined as working locking holes 19 and storage locking holes 20 according to their relative positions. The outer ring 1 is provided with fasteners 6 corresponding to each group of mechanisms, specifically bolts 17 and threaded holes 18 that cooperate with them.

[0020] The locking principle is as follows: When the locking block 3 is pushed out to the working position by the elastic element 4, the bolt 17 is screwed into the threaded hole 18 so that its end is inserted into the working locking hole 19 that is aligned at this time, which can restrict the retraction of the locking block 3 and lock it in the working state. When it is necessary to retract the locking block 3, it is pressed to the storage position. At this time, the bolt 17 is screwed in again so that its end is inserted into the storage locking hole 20 that is aligned at this time, which can press the locking block 3 and lock it in the storage state.

[0021] To prevent the locking block 3 from rotating or coming out of the stop groove 2 during the extension and retraction process, the side of the locking block 3 is provided with a protrusion 10 in the form of an anti-disengagement part 7, and the side wall of the stop groove 2 is provided with a longitudinal guide groove 9. The anti-disengagement part 7 is embedded in the guide groove 9, so that the locking block 3 can only slide smoothly along the guide direction of the groove, and cannot rotate or fall off.

[0022] In this embodiment, the elastic element 4 is preferably a helical spring 11. The bottom of the stop groove 2 is provided with a mounting hole 12 specifically for accommodating the spring 11. To further ensure the stability of the spring 11, a limiting post 13 can be fixedly installed in the mounting hole 12. The spring 11 is sleeved on the outside of the limiting post 13. At the same time, the bottom of the locking block 3 is machined with a guide cavity 14 that slides with the limiting post 13, so that the extension and retraction movement of the locking block 3 is smoother.

[0023] The end face of the outward-extending block 3 is designed as an arc surface 15. This design facilitates the contact of the block 3 with the outside during operation and can smoothly guide the block 3 to retract when subjected to external force.

[0024] The threaded hole 18 for locking is preferably machined as a countersunk hole, so that when the bolt 17 is fully tightened, its head can remain flush with the outer surface of the outer ring 1, thereby avoiding any interference with the installation or subsequent operation of the bearing.

[0025] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
