Description

Technical Field

[0001] This utility model relates to the field of cages, and in particular to a cage structure for deep groove ball bearings. Background Technology

[0002] Deep groove ball bearings are common rolling bearings, consisting of an outer ring, an inner ring, rolling elements (mostly spherical) and a cage. The cage separates the rolling elements and guides them to roll between the inner and outer ring raceways. They mainly bear radial loads, but can also bear small axial loads. The load is transmitted by the rolling elements, and the coefficient of friction is low.

[0003] In the existing technology, there are various types of cages on the market. Combination cages are more common because they are easy to disassemble and replace rolling elements. However, the two connecting frames of a combination cage are usually designed as a single unit. First, regarding the placement of the rolling elements, since the two connecting frames are designed as a single unit, all the rolling elements can only be placed into the limiting groove of one connecting frame before the two connecting frames are fixed together. During the connection of the two connecting frames, it is difficult to ensure the stability of multiple rolling elements at the same time, thus increasing the difficulty of fixing the rolling elements. Second, when replacing a single damaged rolling element, only one complete cage can be removed. Once one cage is removed, the other rolling elements that are constrained in specific positions will be unrestrained, which can easily lead to the rolling elements rolling around and falling off, which is quite inconvenient. Therefore, a deep groove ball bearing cage structure is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a deep groove ball bearing cage structure, in which one of the connecting frames in the combined cage is designed as a segment, so that the rolling elements can be connected one by one during the connection process, reducing the difficulty of connecting the rolling elements. At the same time, when replacing a single damaged rolling element, only the limiting frame of the damaged rolling element needs to be removed, without affecting the fixation of the rolling elements in other positions, thereby improving the practicality of the overall structure of the combined cage.

[0005] To achieve the above objectives, a deep groove ball bearing cage structure is provided, including a connecting frame, a plurality of limiting grooves on the connecting frame, a plurality of screws fixedly connected to the upper surface of the connecting frame, a connecting plate movably connected to the outer surface of the screws, a limiting ring fixedly connected to the connecting plate, and a nut threadedly connected to the outer surface of the screws.

[0006] According to the deep groove ball bearing cage structure, a positioning groove is provided on the connecting plate, and the outer surface of the screw is movably connected to the positioning groove.

[0007] According to the deep groove ball bearing cage structure described above, the screw passes through the nut, and the lower surface of the nut contacts the connecting plate.

[0008] According to the deep groove ball bearing cage structure described above, the lower surface of the connecting plate is in contact with the connecting frame.

[0009] According to the deep groove ball bearing cage structure described above, the connecting frame, connecting plate and limiting ring are all made of stainless steel.

[0010] The above-mentioned solution has the following advantages: By setting up structures such as connecting plates and limiting rings, this solution designs one of the connecting frames in the combined cage as a segment, so that the rolling elements can be connected one by one during the connection process, reducing the difficulty of connecting the rolling elements. At the same time, when replacing a single damaged rolling element, only the limiting frame of the damaged rolling element needs to be removed, without affecting the fixation of the rolling elements in other positions, thereby improving the practicality of the overall structure of the combined cage.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model discloses a deep groove ball bearing cage structure, which includes a connecting frame 1. The connecting frame 1 has multiple limiting grooves 2. Multiple screws 3 are fixedly connected to the upper surface of the connecting frame 1. A connecting plate 4 is movably connected to the outer surface of the screws 3. A limiting ring 5 is fixedly connected to the connecting plate 4. A nut 6 is threadedly connected to the outer surface of the screws 3. A positioning groove 7 is provided on the connecting plate 4. The outer surface of the screws 3 is movably connected to the positioning groove 7. The screws 3 pass through the nut 6. The lower surface of the nut 6 contacts the connecting plate 4. The lower surface of the connecting plate 4 contacts the connecting frame 1. The connecting frame 1, the connecting plate 4, and the limiting ring 5 are all made of stainless steel. It should be noted that two connecting plates 4 and one limiting ring 5 form a limiting frame. The two adjacent limiting frames in the overall structure are only in contact with each other. Therefore, the disassembly and assembly of the limiting frame will not affect the structure of other positions.

[0021] Working principle: A retaining frame is formed between two connecting plates 4 and a limiting ring 5, making one of the connecting frames a segmented design. The retaining frame structure is then formed by the connecting frame 1, the limiting groove 2, and multiple retaining frames. When connecting the rolling elements, the two nuts 6 at the corresponding positions are rotated to unscrew the two nuts 6 from the screws 3, thus releasing the fixation of one of the retaining frames and allowing it to be removed from the overall structure. The rolling element is then placed into the limiting groove 2. After the rolling element is placed, the positioning groove 7 on the retaining frame is inserted into the screws 3. The two nuts 6 are then screwed back onto the two screws 3, thus completing the connection of the rolling element. The same operation is performed at other positions to complete the connection between the retaining frame and the rolling elements. When a damaged rolling element needs to be replaced, the retaining frame on the damaged rolling element is simply unscrewed from the overall structure without affecting the fixation of the rolling elements at other positions.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
