Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a full-fill ball bearing. Background Art

[0002] A full-fill ball bearing is a radial load-bearing ball bearing with more balls than ordinary deep groove ball bearings, so it can withstand greater radial loads. At the same time, it can also withstand slight axial loads and overturning torques. For machines moving at high speeds, full-fill ball bearings can also withstand certain loads. Full-fill ball bearings include an inner ring, an outer ring, and rolling elements. The inner circumference of the outer ring and the outer circumference of the inner ring are provided with grooves for the rolling elements in the middle of one of them, and the middle of the other has a cylindrical surface that contacts and cooperates with the rolling elements. The structure of this bearing allows the inner ring and the rolling elements to move a distance relative to the outer ring to avoid the transmission system from getting stuck. The full-fill ball bearing can be regarded as an upgraded version of the original bearing. It adds full balls between the inner ring and the outer ring, making it have higher load-bearing capacity and rigidity.

[0003] In the prior art full-fill ball bearings, most of the bearings are lubricated by applying lubricating oil on the surface of the bearing, and the amount of lubricating oil cannot be controlled properly. When the amount of lubricating oil is small, there may be greater friction between the rotor and the outer ring, affecting the service life. When the amount of lubricating oil is large, unnecessary waste will be caused. Therefore, it does not meet the existing needs. We have proposed a full-fill ball bearing. Utility Model Content

When the rotating ball rotates, the ball groove is arranged to make the rotating ball rotate in the ball groove, further avoiding the movement of the rotating ball distance, thereby greatly improving the service life of the bearing.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1: This embodiment is intended to promote the solution of the problem that in the existing full-fill ball bearings, most of the bearings are lubricated by applying lubricating oil on the surface of the bearing, and the amount of lubricating oil cannot be controlled properly. When the amount of lubricating oil is small, there may be greater friction between the rotor and the outer ring, which affects the service life. When the amount of lubricating oil is large, it will cause unnecessary waste. Please refer to Figure 1-Figure 6 A full-complement ball bearing comprises a mounting plate 110, a fixing block 100 is fixedly connected to the side of the mounting plate 110, a fixing hole 120 is opened in the middle of the fixing block 100, a mounting ring 130 is fixedly connected to the middle of the mounting plate 110, a placement groove 140 is opened in the middle of the mounting ring 130, a rotating ball 150 is rotatably connected to the middle of the placement groove 140, a connecting ring 160 is connected to the side of the rotating ball 150, a clamping plate 330 is sleeved on the side of the connecting ring 160, and an oil inlet 340 is opened on the side of the mounting ring 130.

[0025] A fixing groove 180 is provided on the side of the rotating ball 150, and a limiting ring 170 is sleeved on the side of the fixing groove 180. The limiting ring 170 limits the rotating ball 150. A ball groove 320 is provided on the side of the locking plate 330. The ball groove 320 is rotatably connected to the rotating ball 150. The rotating balls 150 are arranged in a circular array with the fixing groove 180 as the center. An arc groove 310 is provided on the side of the limiting ring 170. A rotating ball 300 is rollingly installed in the middle of the arc groove 310, and the side of the rotating ball 300 is in contact and connected with the rotating ball 150.

[0026] When the bearing needs to be smeared with lubricating oil during use, the staff will add the lubricating oil into the oil groove 210 through the oil inlet 340. When the rotating ball 150 rotates, the rotating ball 150 will come into contact with the oil outlet bead 200. During the contact, the oil outlet bead 200 will bring out the lubricating oil in the oil groove 210. At this time, when the rotating ball 150 comes into contact with the oil outlet bead 200, the lubricating oil will be smeared on the rotating ball 150. The lubricating oil is smeared on the rotating ball 150 by the oil outlet bead 200, which greatly avoids the waste of manual lubricating oil application.

[0027] In the present embodiment: through the arrangement of the oil inlet 340, the first oil pipe 250, the second oil pipe 290, the oil groove 210 and the oil outlet bead 200, during the operation of the bearing, the lubricating oil in the oil groove 210 can be brought out through the oil outlet bead 200 by the contact of the rotating bead 150 with the oil outlet bead 200 when the rotating bead 150 rotates. Through the contact connection between the oil outlet bead 200 and the rotating bead 150, after the oil outlet bead 200 brings out the lubricating oil, the rotating bead 150 contacts and smears it. During the smearing process, on the one hand, the use of lubricating oil can be saved, and on the other hand, the surface of the rotating bead 150 can be kept with lubricating oil at all times during operation, which solves the problem that most of the bearings mentioned in the above background technology are lubricated by smearing the lubricating oil on the surface of the bearing, and there may be a problem that the appropriate amount of lubricating oil cannot be controlled.

[0028] Embodiment 2: This embodiment is intended to promote the solution of the problem of friction caused by the close distance in the use of the existing full-fill ball bearing. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 6 A support column 230 is connected to the middle of the locking plate 330 , the end of the support column 230 is fixedly connected to the limiting plate 220 , and a limiting piece 240 is fixedly installed at the bottom of the support column 230 , and the limiting piece 240 is in contact with the rotating bead 150 .

[0029] A first oil pipe 250 and a second oil pipe 290 are respectively arranged on both sides of the oil inlet 340. The first oil pipe 250 is arranged above the second oil pipe 290. The sides of the first oil pipe 250 and the second oil pipe 290 are both engaged and connected with the limiting block 260. A slot 280 is opened on the side of the limiting block 260. The side of the limiting block 260 is fixedly connected with a limiting spring 270. One end of the limiting spring 270 is fixedly connected to the slot 280, and the other end of the limiting spring 270 is fixedly connected to the oil groove 210. An oil outlet ball 200 is rollingly installed on the side of the oil groove 210. The first oil pipe 250 and the second oil pipe 290 are both fixedly connected to the oil groove 210.

[0030] When the bearing is running, the rotating ball 150 is limited by the setting of the locking plate 330 and the ball groove 320. When the rotating ball 150 rotates, it is limited by the limiting plate 240 to ensure that the rotating ball 150 rotates in the ball groove 320 as much as possible, avoiding wear and damage to the rotating ball 150 due to the rotation of the rotating ball 150 due to the distance being too close.

[0031] In the present embodiment: by setting the engaging plate 330 and the ball groove 320, when the bearing rotates, the engaging plate 330 has a limiting effect on it, so the engaging plate 330 can limit the rotating ball 150, and the distance of the rotating ball 150 will not change from far to near during the rotation, thereby avoiding the friction problem caused by the too close distance between the rotating balls 150 as much as possible. When the rotating ball 150 rotates, the ball groove 320 is set to make the rotating ball 150 rotate in the ball groove 320, further avoiding the movement of the rotating ball 150, thereby greatly improving the service life of the bearing.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
