Rail type bearing

Abstract

The invention relates to an invention patent of a rail-mounted bearing, which is obtained by transforming a common bearing into the rail-mounted bearing, and the rail-mounted bearing does not need to be lubricated and refueled, has small rotating resistance, saves energy, has a simple and extreme structure and is only second to that of a magnetic suspension bearing, has a service life far longer than that of a conventional bearing, has a temperature rise far lower than that of the conventional bearing and has a limit rotating speed far higher than that of the conventional bearing. The bearing rate of a bearing with the same size is higher than that of a conventional bearing, the bearing can be used as a pressure bearing and a thrust bearing due to relatively strong axial force, the common bearing is an easily-damaged part which is recognized in the world, the main reason of the easily-damaged part is that a retainer slides to isolate a roller during operation and oil must be added due to large resistance, and a rail type bearing does not need the retainer and is not required to be used as a bearing. The rails are used for keeping the equal distances of all the parts, and the remaining defect that the bearing is a quick-wear part is overcome.

Description

[0001] 1. Technical field: A patent for the invention of a track-type bearing: It is an improvement on the bearing that never needs oiling that I invented before. The arc track of the bearing is changed into a trapezoidal track, and the coarse helical teeth are changed into fine helical teeth. It belongs to the field of bearings.

[0002] 2. Background technology: A track bearing. The patent of this invention is improved on the basis of the bearing that never needs oiling that I invented before. Because it was difficult to process before, the improvement solves this problem and reduces the manufacturing cost by 60%. After the improvement, it can be processed very well, assembled simply and has good use effect.

[0003] 3. Content of the invention: A track-type bearing. This patent of the present invention is based on the improvement of the bearing that never needs oiling invented by me before. The arc track of the bearing is changed into a trapezoidal track, and the coarse helical track is changed into a fine helical track. It uses the working principle that coarse screws are prone to breakage, while fine screws are not prone to breakage. The invention improves the service life of the bearing that never needs oiling and increases the axial force. The outer circle of the bearing roller, the outer circle of the bearing inner ring, and the inner circle of the bearing outer ring are all installed on a 45-degree track for meshing and pure rolling operation, ensuring the equidistant distance between the rollers, thereby achieving the goal of not using a bearing cage and solving all the drawbacks of conventional bearings. The processing difficulty is high, especially the arc is very difficult to process. After production, it was found that according to Figure 1 A kind of track bearing, Figure 2 Roller, Figure 3 Outer circle, Figure 4 The inner ring is assembled into Figure 1 Bearings from Figure 1 From the principle, it can be seen that it is a pure rolling star gear rotation, without the rolling and sliding in and out teeth of the involute gear, which is equivalent to net pressure in and out. Because it is a herringbone gear, the force point is at the root of the tooth. By designing a track with a certain angle, it can achieve continuous pure rolling. The best effect is to use two bearings in series, because the difference in linear speed is solved and the resistance is reduced. From the operation of the tooth shape, it can be seen that the in and out is contact without sliding.

[0005] 5. Specific implementation plan: A track bearing, Figure 2 Roller, Figure 3 Outer ring, Figure 4 Inner circle, press Figure 1Bearing assembly, forming a bearing, stringing together a kind of track bearing, can solve the world's difficult problems of circle processing and natural errors. After testing, the rolling and sliding in the operation of extra-wide bearings were solved. During the implementation process, Figure 2 Figure 3 Figure 4 The tooth profiles of all gears are produced using a multi-group forming pin turning tool, which is completed in one go. The tooth profile processing time for each workpiece is only one second to complete all gear geometries.

Claims

1. A patent for the invention of a track bearing, the scope of which is: a track is installed on the main force-bearing roller of the bearing, between the roller and the inner and outer rings, and the track is herringbone-shaped. The surface of the roller is the force-bearing surface, and the tooth roots of the inner and outer rings are the force-bearing surfaces. Its characteristics are that when the bearing rotates, the tooth tip surface of the roller and the tooth roots of the inner and outer rings are the main force-bearing surfaces. The gears of this structure are not like involute gears that roll and slide in and out, but roll on the track. No matter in which direction, it is pure rolling operation, no sliding occurs, and no lubricating oil is required. The gears of the outer ring are trapezoidal, and the teeth of the rollers are The wheel is also trapezoidal. After careful calculation, the bevel of the gear does not slide when entering and exiting, and it enters without friction. When the bearing rotates, the gear rolls purely along the herringbone track, thereby achieving the purpose of the bearing being able to be used without adding lubricating oil. After testing, compared with the bearing that never needs to be lubricated that I invented before, its tooth shape is greatly reduced, and the arc teeth are changed into trapezoidal teeth, which reduces the production cost, increases the service life and reduces the difficulty of assembly. Its application range is applied to pressure bearings and thrust bearings. The application of this structure produces bearings that are flexible in rotation and can run without adding lubricating oil.
