Lubricating-free bearing

Abstract

The invention belongs to the field of bearing manufacturing, relates to an invention patent, belongs to the field of bearing manufacturing, is formed by transforming a common bearing, does not need to be lubricated and refueled, is small in rotation resistance and energy-saving, has the service life far longer than that of a conventional bearing, and improves the width of a raceway by changing a conventional double-flange bearing into a bearing with a single flange in the middle; the main reason for vulnerability is that the retainer slides to isolate the rollers during operation and oil must be added due to large resistance, the retainer is not required to isolate the rollers, a non-lubrication gear is additionally arranged for replacement, the rollers are ensured not to lean against each other, and three reference circle stress points are designed on each roller stress point on a gear reference circle, so that the roller bearing is not required to be abraded, and the service life of the roller bearing is prolonged, and the service life of the roller bearing is prolonged. And the retainer of the conventional bearing is removed, so that the rollers never lean against each other when the bearing is in operation, and the defect that the bearing is a quick-wear part is overcome.

Description

[0001] 1. Technical field: The patented, lubrication-free bearing of this invention is mainly used in the technical field of bearing product manufacturing.

[0002] 2. Background technology: The patented, lubrication-free bearing of this invention improves the drawback that all rolling bearings in the world must be refueled. All rolling bearings in the world will be damaged by friction between the cage and the roller when no refueling occurs. The newly invented bearing solves this difficult problem in the world.

[0003] 3. Invention content: The patented, lubrication-free bearing of this invention uses Figure 1 This is the working principle diagram of the star gear speed changer. Figure 1 In the figure, any four teeth of the planetary gear transmission are selected as a representation of all teeth, and the design is Figure 6 The gear meshing pattern you see, Figure 6 You can see that there are three contact points between the four teeth. Figure 1 There are two contact points between the four teeth. These three contact points are located on the pitch circles of the two gears, that is, between the inner ring and the roller, and between the roller and the outer ring. The designed tooth shapes are Figure 6 The tooth shape with three contact points between the teeth can be seen. With this improvement, it becomes the principle diagram of lubrication-free bearing or lubrication-free transmission. Figure 3 Gears, bearings deemed to be lubrication-free Figure 3 Inner circle, Figure 3 A gear that goes around the Figure 2 , as the roller of the bearing, the outermost gear Figure 4 As the outer ring of the bearing, the lubrication-free bearing uses a gear that is mainly subjected to pure rolling on the common pitch circle of the two gears. Since the gears are reduced to a size that is smaller than the pitch circle, three force points can be seen on the pitch circle. Figure 6 In this case, when the gear rotates, there will be at least two main force points. These two main force points always maintain the static pressure of the gear in and out during rolling rotation, eliminating the two force points of the involute gear, and rolling and sliding in and out. Due to this improvement, such gear transmission does not produce sliding friction. The intuitive difference between them is that the involute gear has two force points in rolling and sliding rotation, while the gear of the lubrication-free bearing has at least three force points in pure rolling rotation when rotating, thereby realizing the working principle of the lubrication-free bearing. According to the design technical requirements, the force points of the raceway are changed from one to more than two, which improves the bearing capacity of the bearing and has the function of the gear, achieving the use function of the bearing without a cage, eliminating the sliding wear of the bearing cage on the roller, thereby realizing the lubrication-free bearing, and solving the problem of bearing oiling after improvement. 4.

[0010] 5. Specific implementation method: The patent of this invention is to improve the normal cylindrical roller bearing by adding gears. Figure 2 The bearing rollers, Figure 3 The inner ring of the bearing, Figure 4 It is the outer ring of the bearing, assembled into Figure 1 Schematic diagram of the appearance of the lubrication-free bearing, from Figure 1 As can be seen from the above, it is a bearing based on the rotation principle of a star gear. Figure 5 It can be seen that Figure 1 A cross-sectional view from Figure 6 It can be seen that Figure 1 An enlarged view of the gear meshing assembly. Figure 1 The gear you can see does not have three force points on the pitch circle. This is because this is a schematic diagram. If you draw it in an enlarged way, Figure 6 The gear is too small to be seen clearly. The bearing flanges were previously on both sides, but are now in the middle. Figure 2 , Figure 3 , Figure 4 , Install to Figure 1 On the composition Figure 5 A bearing assembly. On long bearings, now it is best to use two bearings in series, because the difference in linear speed is solved and the resistance is reduced. Using machining center equipment and CNC machine tools, one-time processing Figure 2 , Figure 3 , Figure 4 The parts cannot be assembled during assembly. We use split assembly, which means Figure 2 , Figure 3 , Figure 4 Parts, any part Figure 2 , Figure 3 , Figure 4 The parts are divided into two sections from the middle of the length. After processing, they are assembled. After assembly, they can be fixed by welding and riveting to form a combination. Figure 2 , Figure 3 , Figure 4 parts, ensuring basic dimensions, from Figure 2 , Figure 3 , Figure 4 As can be seen in the parts diagram, they are all spur gears, assembled into Figure 5 Finally, you can see the cross-section of the bearing. During assembly, the rollers are equidistant and there is enough space between the rollers to ensure that there is no obstruction. The force is designed to be on the common pitch circle, which is the pure rolling force point of the rollers. The main force of the bearing is on the pitch circle, which performs pure rolling, so that the rollers keep rotating at equal distances. When running at high speed, this kind of bearing does not produce a rise in bearing temperature. Based on this, the plan is implemented and the lubrication-free bearing is produced, which achieves the ideal effect after testing.

Claims

1. Invention patent, lubrication-free bearing, technical features are: using the principle diagram of star gears, the involute gears used for star gears are miniaturized, so small that on the common contact pitch circle of two gears, the gear teeth are drawn with parabolas. When the drawn gear teeth are in working meshing, at one roller force point, it can be seen that there are three contact points of the same type on the contact points of two adjacent teeth. The method of distinguishing is that ordinary involute teeth can only see two pitch circle contact points. Because in this case, when the gear rotates, the two teeth are always stressed at the same time, and the other tooth rolls, and it can enter the next group of rolling after rolling a small distance, thus resulting in the technical feature that the bearing rollers do not slide when rotating. In order to explain this abstract technology, if the sun and the moon are both very round, and the sun and the moon are both installed with small gears, and the moon revolves around the sun, when rolling, these small gears will not slide at all, and there will only be static pressure at the opening without wear. This characteristic technology is protected by invention patents, and this characteristic technology is used for bearing manufacturing protection and gear manufacturing protection.
