Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to a low-noise rolling bearing. Background Art
[0002] Bearings are an important component that can be used in contemporary equipment. Since some parts of the equipment need to be fixed and can also rotate, bearings need to be assembled to achieve this effect. The use of bearings can not only fix the position and rotation, but also reduce the friction coefficient when the parts move, thereby improving the rotation accuracy and speed of the device.
[0003] During the use of traditional bearings, since the transmission function is achieved through the cooperation of balls and the outer ring of the inner bearing, the balls will always be in contact with the outer ring of the inner bearing during long-term use, thereby increasing the wear of the balls and the outer ring of the inner bearing. At the same time, after long-term use, the highly frictional bearings will become loose, causing the bearings to produce greater noise during rotation. Utility Model Content
[0004] In order to make up for the above deficiencies, the utility model provides a low-noise rolling bearing.
[0005] The utility model is achieved in this way:
[0006] A low-noise rolling bearing comprises a bearing outer ring and a bearing inner ring, the bearing outer ring is provided with a groove inside, and the bearing inner ring is installed inside the groove, sealing sheets are installed on both sides of the top of the groove, a retaining frame is installed inside the groove, and a plurality of through holes are equidistantly provided inside the retaining frame, a plurality of through holes are vertically installed inside the through holes, and rollers are sleeved on the outsides of the plurality of rotating rods, an oil filling pipe is inserted into one side of the bearing outer ring, and an oil filling port is provided inside the oil filling pipe, a flow groove is provided inside the bearing outer ring, and one end of the oil filling pipe is connected to the flow groove, a lubrication mechanism is provided inside the bearing outer ring, and the lubrication mechanism comprises a baffle plate, the through hole retaining frame is provided with mounting grooves on both sides of the through hole, and a fixing mechanism is provided inside the mounting groove, and the fixing mechanism comprises a limit block.

[0008] The beneficial effect of adopting the above further solution is that by installing a sealing cover, the oil filling port is sealed when oil is not needed, and the sealing cover can be carried by the connecting belt without being lost or dropped.
[0009] Furthermore, a plurality of oil collecting grooves are equidistantly arranged inside the outer ring of the bearing, and the oil collecting grooves are connected to the flow grooves, a baffle plate is installed inside the oil collecting groove, and a plurality of filter holes are arranged inside the baffle plate.
[0010] The beneficial effect of adopting the above further solution is that, by installing the baffle plate, the lubricating oil flows through the flow groove to the inside of the oil collecting groove, and then slowly flows through the filter holes in the baffle plate to the several through holes of the retaining frame.
[0011] Furthermore, a spring is connected to one side of the interior of each of the installation slots, and one end of the spring is connected to a fixing block, and one end of the fixing block is semi-arc-shaped.
[0012] The beneficial effect of adopting the above further solution is that, by installing a spring, the fixing block can be driven to move, so as to facilitate the rolling of the roller, and at the same time, the roller can be fixed during the rolling.
[0013] Furthermore, both sides of the interior of the installation groove are provided with limiting grooves, and limiting blocks are slidably installed inside a pair of the limiting grooves, and the pair of limiting blocks are interconnected with the exterior of the fixed block.
[0014] The beneficial effect of adopting the above further solution is that, by installing the limiting block, the fixed block can be easily moved in the limiting groove, and the movement of the fixed block can be supported and limited.
[0015] The beneficial effects of the utility model are as follows: the utility model obtains a low-noise rolling bearing through the above design. During the long-term high-speed rotation of the bearing, the bearing and the outer ring of the bearing will generate higher friction and noise. The lubricating oil is input into the flow groove through the oil filling port, and the lubricating oil is transported to the inside of the through hole through the fine filter holes in the baffle plate, so that a number of rollers are stained with the lubricating oil, which increases the lubricity of the rollers and reduces the friction between the rollers and the inner wall of the outer ring of the bearing. The sealing cover is used to seal the oil filling port when no oil is needed. The sealing cover can be carried through the connecting belt without being lost or dropped. At the same time, when the roller rotates, a pair of fixed blocks are squeezed, and the spring drives the fixed blocks to move, thereby increasing the stability of the roller and preventing the roller from shaking and generating loud noise after long-term rolling.

[0026] Embodiment 2 of the utility model of a low-noise rolling bearing
