Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically a dustproof bearing with a baffle structure. Background Technology

[0002] Bearings are crucial basic components in the mechanical field. Whether it's a high-speed aircraft engine, a precision machine tool spindle, or an everyday household appliance motor, the stable operation of bearings is essential for the normal functioning of equipment. With the increasingly diverse application scenarios of bearings, in harsh environments such as mining machinery and construction equipment, large amounts of dust can easily penetrate the interior of the bearing and adhere to the surface of the rollers. This not only significantly increases the bearing's coefficient of friction and reduces its operating efficiency but also accelerates bearing wear, and in severe cases, can even lead to bearing failure.

[0003] To address this issue, dustproof designs with baffle structures are widely used. However, in actual operation, the continuous vibration generated during bearing operation makes it difficult for the baffles to remain stable, resulting in loosening and displacement. This weakens the dustproof effect, affects the service life of the bearing, and impacts the reliability of the equipment.

[0004] To address this issue, a dustproof bearing with a baffle structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a dustproof bearing with a baffle structure, which has the advantage of strong stability and solves the problem that the baffles of existing dustproof bearings with baffle structures are prone to loosening and displacement under operating vibration.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dustproof bearing with a baffle structure, comprising a bearing ring, a dustproof component installed on the bearing ring, the dustproof component comprising a first baffle and a second baffle, a connecting rod installed on the first baffle, the end of the connecting rod away from the first baffle passing through the bearing ring and through the second baffle, and having an anti-slip nut threadedly installed thereon;

[0007] The bearing race is provided with a stepped groove, which is used to limit the position of the dustproof component on the bearing race.

[0008] Preferably, the bearing rings include an outer ring and an inner ring, and rolling elements are mounted on the opposite side of the outer ring and the inner ring via a cage.

[0009] In the design, the bearing ring adopts an outer ring and inner ring structure. Rolling elements are installed on the opposite side of the outer ring and inner ring through a cage, realizing the basic rotation function of the bearing. The cage has the function of fixing the position of the rolling elements, so that the rolling elements can roll stably on the appropriate track, ensuring the smooth operation of the bearing.

[0010] Preferably, the cage has a first reserved hole located on the opposite side of two adjacent rolling elements, and the diameter of the first reserved hole is larger than the diameter of the connecting rod.

[0011] In the design, the cage has a first reserved hole, which is located on the opposite side of two adjacent rolling elements. The design of the first reserved hole having a diameter larger than that of the connecting rod allows the connecting rod to pass smoothly through the cage, ensuring that the dustproof component is not obstructed during installation and making the installation of the dustproof component more convenient.

[0012] Preferably, the second baffle is sized to match the first baffle, and the second baffle has a second reserved hole arranged in a ring array for the connecting rod to pass through.

[0013] In the design, the second baffle is sized to match the first baffle, and the second baffle has a second reserved hole in a ring array. The design of using the second reserved hole for the connecting rod to pass through enables the first baffle and the second baffle to be connected by the connecting rod, so that the first baffle and the second baffle can together form a dustproof component, which can play a better role in dust prevention inside the bearing.

[0014] Preferably, the top height of the anti-slip nut is lower than the top height of the outer and inner rings.

[0015] In the design, the top height of the anti-slip nut is lower than the top height of the outer and inner rings. This design ensures that the anti-slip nut does not protrude from the bearing rings, preventing interference between the anti-slip nut and other components during bearing operation, thus ensuring the normal operation of the bearing as a whole and reducing the risk of damage caused by interference.

[0016] Preferably, the stepped groove includes a first stepped groove and a second stepped groove, the first stepped groove being formed at the upper and lower ends of the inner wall of the outer ring, and the second stepped groove being formed at the upper and lower ends of the outer wall of the inner ring.

[0017] The curvature of the first step groove and the second step groove are respectively matched with the inner and outer circumferential arc dimensions of the first or second baffle.

[0018] In the design, the stepped groove includes a first stepped groove and a second stepped groove. The first stepped groove is formed at the upper and lower ends of the inner wall of the outer ring, and the second stepped groove is formed at the upper and lower ends of the outer wall of the inner ring. The curvature of the first stepped groove and the second stepped groove are respectively matched with the inner and outer circumferential arc dimensions of the first or second baffle. This enables the stepped groove to effectively limit the dustproof component, making the position of the dustproof component on the bearing ring more stable. The use of this matching curvature design ensures a tight fit between the dustproof component and the bearing ring, further improving the dustproof effect and the overall stability of the bearing.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model achieves the effect of tightly connecting the first and second baffles to the bearing ring by setting up a dustproof assembly consisting of a first baffle and a second baffle, and installing a connecting rod on the first baffle. The connecting rod passes through the bearing ring and the second baffle and is threaded with an anti-slip nut.

[0021] Meanwhile, stepped grooves are set on the bearing race to limit the position of the dustproof component, which further restricts the position of the dustproof component on the bearing race. This makes it difficult for the dustproof component to loosen or shift when the bearing vibrates during operation, solving the problem that the baffles of existing dustproof bearings with baffle structures are easy to loosen and shift under operating vibration, and has the advantage of strong stability.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one embodiment of the present invention is provided: a dustproof bearing with a baffle structure, including a bearing ring 1, a dustproof component 2 installed on the bearing ring 1, the dustproof component 2 including a first baffle 21 and a second baffle 22, a connecting rod 211 installed on the first baffle 21, the end of the connecting rod 211 away from the first baffle 21 passes through the bearing ring 1 and through the second baffle 22 and is threaded with an anti-slip nut 212;

[0030] The bearing ring 1 is provided with a stepped groove, which is used to limit the position of the dustproof component 2 on the bearing ring 1.

[0031] Specifically, by setting up a dustproof assembly 2 consisting of a first baffle 21 and a second baffle 22, and installing a connecting rod 211 on the first baffle 21, and threading an anti-slip nut 212 through the bearing ring 1 and the second baffle 22, the effect of tightly connecting the first baffle 21 and the second baffle 22 to the bearing ring 1 is achieved.

[0032] Meanwhile, a stepped groove is provided on the bearing ring 1 to limit the position of the dustproof component 2, which further restricts the position of the dustproof component 2 on the bearing ring 1. This makes it difficult for the dustproof component 2 to loosen or shift when the bearing vibrates during operation, thus solving the problem that the baffles of the existing dustproof bearings with baffle structures are easy to loosen and shift under operating vibration, and has the advantage of strong stability.

[0033] Example 2

[0034] To enable the basic rotational function of the bearing and to facilitate the installation of dustproof components, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the bearing ring 1 includes an outer ring 11 and an inner ring 13. Rolling elements 12 are mounted on the opposite side of the outer ring 11 and the inner ring 13 via a cage 14.

[0035] Specifically, the bearing ring 1 adopts a structural design of outer ring 11 and inner ring 13. Rolling elements 12 are installed on the opposite side of the outer ring 11 and inner ring 13 through a cage 14, realizing the basic rotation function of the bearing. The cage 14 has the function of fixing the position of the rolling elements 12, so that the rolling elements 12 can roll stably on a suitable track, ensuring the smooth operation of the bearing.

[0036] Furthermore, the cage 14 is provided with a first reserved hole 141, which is located on the opposite side of two adjacent rolling elements 12, and the diameter of the first reserved hole 141 is larger than the diameter of the connecting rod 211.

[0037] Specifically, the cage 14 has a first reserved hole 141, and the first reserved hole 141 is located on the opposite side of two adjacent rolling elements 12. The design of the first reserved hole 141 having a larger diameter than the connecting rod 211 allows the connecting rod 211 to pass smoothly through the cage 14, ensuring that the dustproof component 2 is not obstructed by the cage 14 during installation, making the installation of the dustproof component 2 more convenient.

[0038] Furthermore, the second baffle 22 is sized to match the first baffle 21, and the second baffle 22 has a second reserved hole 221 arranged in a ring array, through which the connecting rod 211 passes.

[0039] Specifically, the second baffle 22 is sized to match the first baffle 21, and the second baffle 22 has a second reserved hole 221 arranged in a ring array. The design of using the second reserved hole 221 for the connecting rod 211 to pass through enables the first baffle 21 and the second baffle 22 to be connected by the connecting rod 211, so that the first baffle 21 and the second baffle 22 can together form the dustproof component 2, which plays a better role in dust prevention inside the bearing.

[0040] Furthermore, the top height of the anti-slip nut 212 is lower than the top height of the outer ring 11 and the inner ring 13.

[0041] Specifically, the top height of the anti-slip nut 212 is lower than the top height of the outer ring 11 and the inner ring 13. This design ensures that the anti-slip nut 212 does not protrude from the bearing race 1, thus preventing the anti-slip nut 212 from interfering with other components during bearing operation, ensuring the normal operation of the bearing as a whole, and reducing the risk of damage caused by interference.

[0042] Example 3

[0043] To achieve precise positioning of the dustproof components and improve the overall stability and dustproof effect of the bearing, such as Figure 2 , Figure 3 As shown, in this embodiment, the stepped groove includes a first stepped groove 111 and a second stepped groove 131. The first stepped groove 111 is formed at the upper and lower ends of the inner wall of the outer ring 11, and the second stepped groove 131 is formed at the upper and lower ends of the outer wall of the inner ring 13.

[0044] The curvature of the first step groove 111 and the second step groove 131 are respectively matched with the inner and outer circumferential arc dimensions of the first baffle 21 or the second baffle 22.

[0045] Specifically, the stepped groove includes a first stepped groove 111 and a second stepped groove 131. The first stepped groove 111 is formed at the upper and lower ends of the inner wall of the outer ring 11, and the second stepped groove 131 is formed at the upper and lower ends of the outer wall of the inner ring 13. The curvature of the first stepped groove 111 and the second stepped groove 131 are respectively matched with the inner and outer circumferential arc dimensions of the first baffle 21 or the second baffle 22. This enables the stepped groove to effectively limit the dustproof component 2, making the position of the dustproof component 2 on the bearing ring 1 more stable. This matching curvature design ensures a tight fit between the dustproof component 2 and the bearing ring 1, further improving the dustproof effect and the overall stability of the bearing.

[0046] When using this utility model, inspect the bearing ring 1, dustproof component 2 and other related parts to ensure that each component is undamaged, free of impurities, and that the dimensions match.

[0047] First, place the rolling elements 12 in the corresponding positions of the cage 14 according to the design requirements. Then, install the cage 14 with the rolling elements 12 assembled on the opposite side of the outer ring 11 and the inner ring 13 to complete the basic assembly of the bearing ring 1.

[0048] Place the first baffle 21 at the corresponding position of the stepped groove of the bearing ring 1. Use the stepped groove to initially limit the first baffle 21 to ensure that the installation position of the first baffle 21 is accurate. Then, make the end of the connecting rod 211 away from the first baffle 21 pass through the first reserved hole 141 on the inner cage 14 of the bearing ring 1 and the second reserved hole 221 on the second baffle 22 in sequence. Thread an anti-slip nut 212 onto one end of the connecting rod 211 and tighten the anti-slip nut 212 with a socket wrench or other tools to make the first baffle 21 and the second baffle 22 tightly fixed on the bearing ring 1. At the same time, ensure that the top height of the anti-slip nut 212 is lower than the top height of the outer ring 11 and the inner ring 13 to avoid interference.

[0049] After installation, check whether the dustproof component 2 is securely installed and whether the bearing ring 1 rotates smoothly. Ensure that the entire bearing is installed correctly and without any looseness, jamming or other abnormalities. If there are any problems, adjust them in time.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
