Description

Technical Field

[0001] This utility model relates to the field of deep groove ball bearing technology, and more specifically, to a deep groove ball bearing oil dripping device. Background Technology

[0002] In actual operation, deep groove ball bearings experience continuous friction between their inner and outer rings and the balls. The grooves on the inner and outer rings, designed to hold the balls, contribute to wear. Therefore, it is crucial to inject lubricating oil into the grooves of the deep groove ball bearing before use to form a continuous and uniform oil film on all friction surfaces. This oil film not only effectively reduces the coefficient of friction, adhesive wear, and abrasive wear, but also removes abnormal temperature rises caused by contact loads and friction through the heat conduction of the lubricating medium, thus ensuring stable bearing operation.

[0003] Traditional oil dripping devices face significant limitations during operation: if the bearing is placed vertically for oil dripping, the lubricating oil can enter the groove by gravity; however, due to its vertical placement, the lubricating oil will concentrate at the bottom of the groove, resulting in incomplete oil film coverage in other areas of the groove; if the bearing is placed horizontally for oil dripping, the oil dripping device has difficulty accurately injecting oil into the groove due to the obstruction of the ball bearings.

[0004] To address the aforementioned challenges, there is an urgent need to develop a new type of deep groove ball bearing oil dripping device that can evenly drip lubricating oil onto various parts of the groove, thereby forming a continuous and uniform oil film on the groove. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model proposes a deep groove ball bearing oil dripping device.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A deep groove ball bearing oil dripping device includes a clamping seat and an oil dripping device body. The oil dripping device body includes an oil dripping nozzle. The clamping seat is used to clamp the outer ring of the deep groove ball bearing, thereby keeping the deep groove ball bearing in a vertical state. The clamping seat is provided with a drive system that pushes the inner ring of the deep groove ball bearing to rotate. The oil dripping nozzle is inclined and its oil outlet faces the bottom ball surface of the deep groove ball bearing.

[0008] The outer ring of the deep groove ball bearing is firmly clamped by a clamping seat, keeping the bearing vertical. The oil drip nozzle is tilted, with the outlet facing the bottommost ball surface of the bearing. When the dripping device starts working, lubricating oil flows from the nozzle and drips directly onto the bottommost ball. As the inner ring rotates, the balls continue to roll, carrying the dripped lubricating oil to all parts of the groove, including the sides and areas away from the drip nozzle, thus forming a continuous and uniform oil film across the entire groove.

[0009] By tilting the oil drip nozzle to drip oil onto the surface of the bottom ball bearing and combining this with the rotation of the inner ring to roll the balls, the problem of lubricating oil concentrating at the bottom of the groove and incomplete oil film coverage in other areas, which is common with traditional vertical oil dripping, is effectively solved. At the same time, it avoids the difficulty of accurately injecting oil into the groove due to ball obstruction, which is common with horizontal oil dripping. This ensures that the lubricating oil evenly covers all parts of the groove, forming a continuous and uniform oil film, comprehensively improving lubrication performance, reducing localized wear caused by uneven lubrication, and extending bearing life.

[0010] Preferably, the clamping seat includes a base plate, an electric guide rail is provided on the base plate, two electric sliders are provided inside the electric guide rail, and a clamping plate is provided on the electric sliders.

[0011] The electric slider drives the two clamping plates to move towards each other, thereby clamping the outer ring of the deep groove ball bearing.

[0012] Preferably, an upward-opening arc-shaped plate is fixed on the inner side wall of the clamping plate. The arc-shaped plate matches the outer ring of the deep groove ball bearing, and the horizontal thickness of the arc-shaped plate is less than half the thickness of the outer ring of the deep groove ball bearing. When the clamping plate closes to clamp the outer ring of the bearing, the inner surface of the arc-shaped clamping part contacts the outer wall of the outer ring, and the distance between the side walls of the two clamping plates is always greater than zero.

[0013] When using this oil-drip device, the deep groove ball bearing is first placed on two arc-shaped plates. Since the distance between the two arc-shaped plates is less than the thickness of the deep groove ball bearing, the bearing will naturally lock between the plates, achieving initial positioning. Subsequently, the electric slider drives the clamping plates to move towards each other, causing the arc-shaped plates to gradually conform to the outer ring of the deep groove ball bearing. The horizontal thickness of the arc-shaped plates is designed to be less than half the thickness of the outer ring of the deep groove ball bearing, ensuring that the two arc-shaped plates do not contact each other during the clamping process. As the clamping plates continue to move, the deep groove ball bearing is finally stably clamped in a vertical position, providing a reliable foundation for subsequent oil dripping and inner ring rotation operations.

[0014] Preferably, the upper end face of the clamping plate is provided with an arc-shaped notch.

[0015] The curved notch provides an unobstructed dripping channel for the oil drip nozzle, greatly improving the accuracy of dripping. Operators can easily align the oil drip nozzle with the bottom ball surface, ensuring that the lubricating oil drips accurately to the critical position, avoiding drip deviation caused by the clamping plate, laying the foundation for the formation of a uniform and continuous oil film on the groove, and effectively improving the lubrication effect of deep groove ball bearings.

[0016] Preferably, the drive system includes a drive motor, a rotating shaft, a telescopic bracket, and a friction plate; the drive motor is fixed on the base plate and drives the rotating shaft to rotate through a coupling; a telescopic bracket is fixed to the end of the rotating shaft, and a friction plate is provided at the end of the telescopic bracket, which can abut against the inner ring sidewall of the deep groove ball bearing under the action of the telescopic bracket.

[0017] The telescopic bracket adjusts its extension to allow the friction plate at the end to gradually approach the inner ring sidewall of the deep groove ball bearing until the friction plate is tightly pressed against the inner ring sidewall, ensuring sufficient friction between the two.

[0018] Subsequently, the drive motor fixed to the base plate is powered on, and the rotational power generated by the motor is transmitted to the shaft through the coupling. Since the friction plate is firmly pressed against the inner ring sidewall of the deep groove ball bearing, the rotation of the shaft drives the telescopic bracket to rotate as well. This friction between the friction plate and the inner ring sidewall drives the inner ring of the deep groove ball bearing to rotate synchronously. During the oil dripping process, the rotation of the inner ring causes the balls to roll, allowing the lubricating oil dripping from the drip nozzle onto the balls to be more evenly distributed within the grooves of the deep groove ball bearing under the action of centrifugal force and ball rolling, achieving efficient and uniform lubrication.

[0019] Preferably, the friction plate is circular, and its diameter is the same as the outer wall diameter of the inner ring of the deep groove ball bearing.

[0020] The circular friction plate has the same diameter as the outer wall diameter of the inner ring, ensuring a large and uniform contact area between the friction plate and the inner ring. This larger contact area makes the friction plate more stable and reliable when driving the inner ring, effectively preventing slippage and ensuring uniform speed of the deep groove ball bearing's inner ring during rotation. This provides stable power support for the even distribution of lubricating oil within the grooves, thereby improving lubrication performance.

[0021] Preferably, a rubber layer is provided on the end face of the friction plate near the deep groove ball bearing.

[0022] Rubber material itself has a high coefficient of friction. Adding a rubber layer to the friction plate significantly increases the friction between the friction plate and the inner ring of the deep groove ball bearing. Attached Figure Description

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0030] Example

[0031] like Figures 1-4 As shown, the deep groove ball bearing oil dripping device in this embodiment mainly consists of a clamping seat and an oil dripping device body 120.

[0032] The clamping base includes a base plate 1101, on which an electric guide rail 1102 is mounted. Two electric sliders 1103 are provided inside the guide rail, and a clamping plate 1104 is connected to the slider.

[0033] The inner wall of the clamping plate 1104 is fixed with an arc-shaped plate 130 that opens upward and matches the outer ring of the deep groove ball bearing. The horizontal thickness of the arc-shaped plate 130 is less than half the thickness of the outer ring of the deep groove ball bearing. When the two clamping plates 1104 are closed to clamp the outer ring of the bearing, the distance between the side walls is always greater than zero, and an arc-shaped notch 140 is opened on the upper end face of the clamping plate 1104.

[0034] The drive system, as part of the clamping seat, includes a drive motor 1501 fixed on the base plate 1101. The motor drives the rotating shaft 1502 to rotate through a coupling. A telescopic bracket 1503 is fixed at the end of the rotating shaft 1502. The end of the bracket is provided with a circular friction plate 1504 with a diameter consistent with the outer wall diameter of the inner ring of the deep groove ball bearing and a rubber layer near the bearing end face.

[0035] The main body 120 of the oil dripping device includes an oil dripping nozzle 1201 that is inclined and has its oil outlet facing the bottom ball surface of the deep groove ball bearing. The oil inlet pipe 1202 is used to introduce oil into the oil dripping nozzle 1201. The method for adjusting the angle of the oil dripping nozzle 1201 is a common existing technology, which will not be described in detail here.

[0036] Its specific operating principle is as follows:

[0037] When using this oil dripping device, the deep groove ball bearing is first placed on two arc-shaped plates 130, and initial positioning is achieved by using the distance between the two arc-shaped plates 130 to be less than the thickness of the bearing. Next, the electric slider 1103 drives the clamping plate 1104 to move towards each other, so that the arc-shaped plates 130 fit against the outer ring of the deep groove ball bearing, and finally the bearing is stably clamped in a vertical position. At this time, the telescopic bracket 1503 is adjusted so that the friction plate 1504 abuts against the side wall of the inner ring of the deep groove ball bearing, and the drive motor 1501 drives the rotating shaft 1502 to rotate through the coupling, relying on the friction force between the friction plate 1504 and the side wall of the inner ring to drive the inner ring to rotate. When the oil dripping device is working, lubricating oil flows out from the inclined oil dripping nozzle 1201 and drips onto the bottom ball. As the inner ring rotates, the ball rolls and carries the lubricating oil to all parts of the groove, forming a continuous and uniform oil film on the groove.

[0038] The above setup effectively solves the problems of traditional vertical oil dripping where the lubricating oil is concentrated at the bottom of the groove and the oil film is not fully covered in other areas, and the problem of horizontal oil dripping where the oil is difficult to accurately inject due to the obstruction of the ball. It ensures that the lubricating oil evenly covers all parts of the groove and comprehensively improves the lubrication effect.

[0039] The arc-shaped notch 140 on the upper surface of the clamping plate 1104 provides an unobstructed oil dripping channel for the oil dripping nozzle 1201, which greatly improves the accuracy of oil dripping, ensures that the lubricating oil is accurately dripped to the key position, and helps to form a uniform and continuous oil film.

[0040] The drive system adjusts the contact between the friction plate 1504 and the inner ring via the telescopic bracket 1503. The motor drives the rotating shaft 1502 and the friction plate 1504 to rotate the inner ring, ensuring stable rotation. The circular friction plate 1504 has the same diameter as the outer wall of the inner ring, ensuring a large and uniform contact area, reducing slippage of the inner ring, and providing stable power for uniform distribution of lubricating oil.

[0041] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
