Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] figure 1 A schematic structural view of the roller bearing of the first embodiment of the present invention is given schematically. Figure 2 to Figure 3 A structural schematic diagram of the roller is further provided. The roller 1 is a cylinder, including a roller outer ring 11 and a roller core 12. The roller outer ring 11 is made of bearing steel, and the roller core 12 is made of methyl vinyl silicone rubber. The roller core 12 is located on Inside the roller outer ring 11. The shape of the roller core 12 is a cylinder with the same central axis as the roller 1 . The roller bearing based on the filled roller thus constituted has good vibration and noise reduction performance.

[0017] Figure 4 Shown is a sectional view taken along the axis of the roller in the second embodiment of the present invention. Compared with the first embodiment, the shape o...

Abstract

The invention provides a filling type roller and a corresponding roller bearing based on the same. The filling type roller comprises a roller outer ring and a roller core, wherein the roller outer ring is made of bearing alloy, such as bearing steel. The roller core is positioned inside the roller outer ring and is made of a damping material with a vibration absorbing performance, such as silicone rubber. According to the filling type roller provided by the invention, a traditional hollow roller is filled with the damping material with the vibration absorbing performance; and the filling type roller is applied to the roller bearing, so that the bearing capacity of the bearing can be ensured and favorable structure damping characteristic can be obtained, and further the vibration and noise of the bearing are reduced.

Description

technical field [0001] This invention relates to rollers and roller bearings. Background technique [0002] The vibration and noise reduction of roller bearings is an urgent problem to be solved in the bearing industry. [0003] Hollow roller bearings can achieve the purpose of reducing vibration and noise to a certain extent. Hollow roller bearings can be designed by changing the traditional solid rollers to hollow rollers. The US patent "Roller bearing" (US: 595328, 1897-12-14) made the roller into a helical structure wound by metal sheets. The US patent "Roller bearing" (US: 785944, 1905-03-28) invented a thin-walled hollow roller bearing. The US patent "Flexible roller for roller bearings" (US: 828387, 1906-08-14) opened some small grooves on thin-walled tubular rollers, and invented a more elastic hollow roller bearing. The French patent "Roller bearing with preloaded hollow rollers" (French: 946559, 1949-06-08) invented a hollow roller bearing using preload. The U...
