Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a flange bearing with lubricating grooves. Background Technique

[0002] A flange bearing is a type of bearing product. Compared with ordinary bearings, a flange is provided at the outer edge of the outer ring of the flange bearing, and it can be directly fixed to equipment or structures through the flange, eliminating the need for a bearing housing. It has great advantages in the connection between the bearing and planar components and is more economical.

[0003] A prior art self-lubricating flange bearing with the publication number CN211574049U adds lubricating oil directly into the bearing through lubricating holes during use. However, there are multiple lubricating holes on this device, which requires multiple additions and is rather troublesome. Moreover, the multiple lubricating holes result in a relatively wide connection surface between the inside and outside of the bearing, and it is easy for the lubricating oil to be thrown out from the lubricating holes when the bearing rolls. In addition, the angle between the inner ring and the outer ring of this bearing is fixed during use, making the axial angle fixed, and it can only be used for a directional shaft, which is not convenient for use in other scenarios. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art, such as troublesome lubricating oil addition and easy leakage, and single use environment, and provides a flange bearing with lubricating grooves.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A flange bearing with lubricating grooves includes an outer ring and an inner ring. An arc-shaped plate, a ring-shaped support frame, and several balls are arranged between the outer ring and the inner ring. The several balls are located between the arc-shaped plate and the inner ring and are distributed in a circular array. The support frame is sleeved on the balls. Annular grooves are opened on the inner wall of the annular plate and the outer side wall of the inner ring. The balls are in contact with the grooves on both sides. An annular cavity is opened on the inner ring. An oil injection hole communicating with the cavity is opened at the top of the inner ring. Several annularly distributed oil outlet holes are opened at the bottom of the cavity, and all the several oil outlet holes are communicated with the grooves. A square flange ring is integrally provided at the bottom of the outer ring, and mounting holes are opened near the four corners of the flange ring.

[0006] In the above, the inner wall of the outer ring and the outer side wall of the movable ring are both arc-shaped, and the outer side wall of the movable ring is in contact with the inner wall of the outer ring. A through hole is opened on the annular plate, and the through hole is communicated with the groove.

[0007] In the above, the outer ring is composed of a first ring and a second ring, and the second ring is inserted into the first ring. The inner walls of the first ring and the second ring are joined to form an arc surface.

[0008] As described above, the flange ring is formed by splicing a first fixing plate and a second fixing plate. The first annular ring is integrally connected to the first fixing plate, and the second annular ring is integrally connected to the second fixing plate.

[0009] As described above, two annular sealing plates are provided between the outer wheel and the inner wheel, and the two sealing plates are distributed on the upper and lower sides of the support frame. Annular grooves are formed on the inner sides of the two sealing plates and the outer side wall of the inner wheel, and the sealing rings are clamped in the grooves on both sides.

[0010] Compared with the prior art, the flange bearing with lubricating grooves has the following beneficial effects:

[0011] First, in the present utility model, an oil injection hole and an annular cavity are formed on the inner wheel to add lubricating oil, and the lubricating oil uniformly flows into the groove through a plurality of annularly distributed oil outlet holes. As the balls rotate, the lubricating oil fills the space between the balls, the annular plate and the inner wheel, realizing the lubrication of the bearing. The oil injection hole is single, which is convenient for adding lubricating oil, and reduces the communication space inside and outside the bearing, so that the lubricating oil is not easy to leak out.

[0012] Second, in the present utility model, the arc surface between the annular plate and the outer wheel is in contact, so that the annular plate can deflect. Thus, the inner wheel can be driven to deflect through the balls and the support frame, so that the axis of the shaft can deflect during movement, which is suitable for different use environments. At the same time.

[0013] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1-6 shown, the present invention provides a technical solution: a flange bearing with a lubricating groove, including an outer wheel 1 and an inner wheel 2. An arc-shaped plate, an annular support frame 5 and a plurality of balls 4 are arranged between the outer wheel 1 and the inner wheel 2. The plurality of balls 4 are located between the arc-shaped plate and the inner wheel 2 and are distributed in an annular array. The support frame 5 is sleeved on the balls 4. Annular grooves are opened on the inner wall of the ring plate 7 and the outer wall of the inner wheel 2. The balls 4 are in contact with the grooves on both sides. An annular cavity is opened on the inner wheel 2. An oil injection hole communicating with the cavity is opened at the top of the inner wheel 2. A plurality of annularly distributed oil outlet holes are opened at the bottom of the cavity, and the plurality of oil outlet holes are all communicated with the grooves. A square flange ring 3 is integrally provided at the bottom of the outer wheel 1, and mounting holes are opened near the four corners of the flange ring 3.

[0023] According to the overall structure of the device, the bearing as a whole is composed of the outer wheel 1, the ring plate 7, the balls 4, the support frame 5, the inner wheel 2 and the flange ring 3. The inner wheel 2 can rotate relative to the outer wheel 1 and the ring plate 7 through the balls 4 and the support frame 5, and the grooves and the support frame 5 limit the movement of the balls 4. Lubricating oil can be added to the annular cavity through the oil injection hole, and the plurality of oil outlet holes can disperse the lubricating oil into the grooves, so as to realize the lubrication between the balls 4 and the ring plate 7 and the inner wheel 2. The flange ring 3 facilitates the installation and fixation of the bearing.

[0024] As Figure 3 shown, the inner wall of the outer wheel 1 and the outer wall of the movable ring are both arranged as arc surfaces, and the outer wall of the movable ring is in contact with the inner wall of the outer wheel 1. A through hole is opened on the ring plate 7, and the through hole is communicated with the groove.

[0025] Through the fitting of the arc surfaces, the ring plate 7 can deflect in the outer wheel 1, so that the inner wheel 2 deflects, which is convenient for axial deflection. The through hole facilitates the lubricating oil to flow into the space between the outer wheel 1 and the ring plate 7 for lubrication.

[0026] As Figure 4As shown in the figure, the outer wheel 1 is composed of a first ring 101 and a second ring 102, and the second ring 102 is inserted into the first ring 101. The inner walls of the first ring 101 and the second ring 102 are joined together to form an arc surface. The flange ring 3 is formed by splicing a first fixing plate 301 and a second fixing plate 302. The first ring 101 is integrally connected to the first fixing plate 301, and the second ring 102 is integrally connected to the second fixing plate 302.

[0027] The outer wheel 1 and the flange are divided into two sleeved components through the first ring 101, the second ring 102, the first fixing plate 301 and the second fixing plate 302, which facilitates the disassembly of the outer wheel 1, and thus facilitates the removal and installation of the internal annular plate 7, the balls 4 and the inner wheel 2, so as to facilitate the overall maintenance of the bearing.

[0028] As Figure 2 , 3 , as shown in Figure 6, two annular sealing plates 6 are provided between the outer wheel 1 and the inner wheel 2, and the two sealing plates 6 are distributed on the upper and lower sides of the support frame 5. Annular grooves are formed on the inner sides of the two sealing plates 6 and the outer side wall of the inner wheel 2, and the sealing rings 8 are clamped in the grooves on both sides.

[0029] The two sides of the balls 4 are sealed by the sealing plates 6 to prevent dust from entering and accumulating between the balls 4, which affects the rolling of the balls 4.

[0030] Working principle: When in use, lubricating oil is injected from the oil injection hole to fill the cavity. After the lubricating oil is injected into the cavity, it flows out dispersedly from several oil outlet holes. As the inner wheel 2 rotates, the balls 4 move and the balls 4 rotate themselves, driving the lubricating oil between the inner wheel 2 and the outer wheel 1, and soaking the balls 4 with the lubricating oil. At the same time, the arc surface between the inner wall of the outer wheel 1 and the arc-shaped plate enables the arc-shaped plate to deflect within the outer wheel 1. The arc-shaped plate can drive the inner wheel 2 to deflect through the balls 4 and the support frame 5. When the balls 4 move in the grooves of the annular plate 7, the lubricating oil is brought into the grooves of the annular plate 7, and the lubricating oil flows into the space between the annular plate 7 and the outer wheel 1 through the through holes, so as to lubricate the space between the outer wheel 1 and the annular plate 7. Two dust-proof plates are used to prevent dust from entering the space between the annular plate 7 and the inner wheel 2, and to avoid dust accumulation between the annular plate 7 and the inner wheel 2, which affects the rolling of the balls 4.
