Lubricating-free bearing

Abstract

The inventor discovers that a star-shaped herringbone helical gear structure is used as a bearing structure, the tooth shape is parabola tooth, angle tooth, involute and the like, when the tooth is tiny to be meshed with two gears, more than two contact points can be seen on the tooth, and at the moment, the transmission force of the gears is changed into pure rolling transmission force, which is the theorem of the inventor; in order to be convenient to manufacture and assemble, the bearing is divided into seven parts, namely a positive spiral inner gear ring, a negative spiral inner gear ring, a positive spiral outer gear ring, a negative spiral outer gear ring, a positive spiral hollow roller and a negative spiral hollow roller, after the parts are placed according to a bearing structure, the positive spiral hollow roller and the negative spiral hollow roller are riveted by a long rivet, and the bearing is manufactured and assembled.

Description

1. Technical field

[0001] The patent of this invention is a lubricant-free bearing, belonging to the field of bearing manufacturing. 2. Background Technology

[0002] Currently, all bearings in operation around the world must be lubricated, which increases operating temperatures, shortens service life, and creates large frictional resistance between the bearing rollers and the cage. The cage creates resistance to the bearing, and comparisons have shown that resistance can reach 14%, making it a vulnerable part on the equipment. 3. Summary of the invention

[0003] The invention patent is a non-lubricated bearing, which solves the problem that bearings are easily damaged parts in the world. The content of this invention is: ( Figure 1 ) is the appearance of a non-lubricated bearing, ( Figure 2 ) is a projection diagram of a non-lubricated bearing, from ( Figure 1 ) can be seen in the figure, there are multiple small bearing rollers ( Figure 9 ), small roller( Figure 9 ) has a herringbone gear, which is connected to the inner ring gear ( Figure 3 )( Figure 4 )、Outer ring gear( Figure 5 )( Figure 6 ) combination, when the bearing is working, the small rollers of these herringbone gears ( Figure 9 ), plays the role of normal bearing roller and also plays the role of bearing support. Figure 9 ) on the helical gear and the inner and outer gear ring teeth correspond to each other, we use involute teeth or other forms of teeth, the root of the tooth is different from the involute teeth, the conventional involute gear, the root of the tooth is not subject to force, we changed it to the main axial force point, its root width is more than 1 times larger than the conventional one, in order to solve the problem of difficult processing, we invented the use of ( Figure 3 )( Figure 4 )( Figure 5 )( Figure 6 )( Figure 7 )( Figure 8 )( Figure 9 )( Figure 10 ) assembly method, solved the problem that we have researched long ago, which could not be processed and assembled. After testing, we found that the smaller the module of the gear, the better the performance. Finally, we decided that when designing the gear module, the involute contact points of the two gears must have three contact points. In this case, the transmission and rolling of the gears are pure rolling phenomena. The purpose of using helical gears is to make up for the suspension phenomenon during the transmission process, and to ensure the bearing pressure and pure rolling operation. According to this theoretical test result, it is found that no welding is required during assembly. Just press ( Figure 2 ) assembled, and ( Figure 10) rivets, rivets in ( Figure 9 ) This kind of bearing is the best one among the more than one hundred pure rolling bearings I have made. It does not need to add lubricating oil. When it rotates at a speed of 8,000 revolutions per minute, the temperature does not change at all after 30 minutes, which achieves the real purpose of the invention. 4.

Figure 3 )( Figure 4 )( Figure 5 )( Figure 6 )( Figure 7 )( Figure 8 )( Figure 9 ) assembled into a graph( Figure 2 ), burn and then ( Figure 10 ) rivet, inserted into ( Figure 7 )( Figure 8 ), firmly riveted, and assembly is complete. The material used is the same bearing steel used for conventional bearings. The gear tooth profiles include involute gears, parabolic gears, ninety-degree angle gears, semicircular gears, and other tooth profiles. Regardless of the tooth profile, the smaller the module, the better the performance. The rack is a herringbone rack, assembled in seven parts. Once assembled, this bearing can be used with similar bearings. Testing has shown that the bearing does not require lubricating oil, which increases service life, reduces resistance, reduces temperature rise, and increases the maximum speed.

Claims

1. The patent of this invention: It is a lubricated bearing. By using this working principle, it can replace various types of bearings. It has the function of changing the bearing to one that does not require oil or a cage. From the structure of the bearing, it can be seen that the bearing is cut into two halves, and then a rivet is riveted on the hollow roller, and then reassembled. All bearing rollers and the inner and outer rings of the bearing are installed with herringbone gears. The herringbone teeth are based on parabolic teeth. The root width is more than twice the tooth thickness. The root is the main force point. The parabola of the tooth is in static pressure and static operation, and the root is in rolling operation. The module of the gear is extremely small. When two gears are meshed together, more than two contact points can be seen. According to the force requirements, the tooth profile can also use involute teeth, semicircular teeth, angular teeth or other tooth profiles.
