[0001] The utility model relates to the technical field of bearings, in particular to a high-speed constant-section thin-wall bearing. Background Art

[0002] High-speed type uniform cross-section thin-wall bearing is an extremely thin bearing section, which realizes the miniaturization and lightweight of the product. The diversity of the product expands its scope of application, and it has thin-walled, small-volume and light-weight equipment.

[0003] Existing uniform-section thin-walled bearings are generally equipped with dust covers to adapt to harsh working environments. However, the side walls of the dust covers are in contact with the inner wall of the bearings, causing a certain resistance to the rotation of the bearings, thereby affecting the speed of the bearings. In addition, the waste lubricating oil thrown out by the bearings during long-term rotation will accumulate in the bearings. Since the dust covers are difficult to remove, the waste lubricating oil cannot be cleaned in time, corroding the bearings and reducing their service life. Utility Model Content

The outer walls of both sides of the retaining frame 103 are provided with two threaded connection cylinders 1031, the inner side walls of the threaded connection cylinders 1031 are threadedly connected with fixing screws 3, and the outer wall of the fixing screws 3 is threadedly connected with a dust cover 2, the front and rear side walls of the outer ring 101 are symmetrically provided with a receiving groove 1011, and the front and rear side walls of the inner ring 102 are symmetrically provided with a receiving groove 2, and the front and rear side walls of the inner ring 102 are symmetrically provided with a receiving groove 1021, and the receiving groove 1011 and the receiving groove 2 1021 are accommodated and matched with the dust cover 2;

[0021] The outer ring and the inner ring of the dust cover 2 are both provided with an outer rib 201, and the two outer ribs 201 are respectively located in the receiving groove 1 1011 and the receiving groove 2 1021, and the outer rib 201 does not contact the receiving groove 1 1011 and the receiving groove 2 1021. The interior of the dust cover 2 is provided with two inner ribs 202, and the inner rib 202 is located between the outer ring 101 and the inner ring 102, and the outer side walls of the inner rib 202 are adjacent to the inner side walls of the outer ring 101 and the inner ring 102 and do not contact each other. The area between the two inner ribs 202 is set as a waste oil collection area 203, and the surface of the dust cover 2 is provided with a screw hole 204 and an oil filling hole 205, and the screw hole 204 and the oil filling hole 205 are both located in the waste oil collection area 203, and the positions of the screw hole 204 and the threaded connection cylinder 1031 correspond to each other, and the inner side wall of the oil filling hole 205 is blocked with a blockage 4. By setting the dust cover 2, the receiving groove 1 1011 and the receiving groove 2 1021, when the dust cover 2 and the thin-walled bearing body 1 are protected, the outer rib 201 of the dust cover 2 is located in the receiving groove 1 1011 of the outer ring 101 and the receiving groove 2 1021 of the inner ring 102, and the outer rib 201 does not contact the receiving grooves, so as to perform preliminary dust protection, and the inner rib 202 of the dust cover 2 is located between the outer ring 101 and the inner ring 102, and the inner rib 202 does not contact the inner side walls of the outer ring 101 and the inner ring 102, so as to perform secondary dust protection to prevent dust from entering the interior of the bearing. It does not contact the inner ring 102 and the outer ring 101, and does not generate friction and resistance with them, thereby ensuring the high-speed rotation of the thin-walled bearing body 1; through the set fixing screw 3, the threaded connecting cylinder 1031, and the waste oil collection area 203, when the bearing rotates, the waste lubricating oil thrown out by its rotation will accumulate in the waste oil collection area 203 of the dust cover 2, reducing the influence of the waste lubricating oil on the rotation of the bearing.

The inner rib 202 of the dust cover 2 is located between the outer ring 101 and the inner ring 102, and the inner rib 202 does not contact the inner side walls of the outer ring 101 and the inner ring 102, so as to perform secondary dust protection and prevent dust from entering the interior of the bearing. Since the dust cover 2 does not contact the inner ring 102 and the outer ring 101, no friction or resistance is generated therebetween, thereby ensuring the high-speed rotation of the thin-walled bearing body 1.

[0023] When the bearing rotates, the waste lubricating oil thrown out by the rotation will accumulate in the waste oil collection area 203 of the dust cover 2, reducing the influence of the waste lubricating oil on the rotation of the bearing. When cleaning the waste lubricating oil, the fixing screw 3 is removed from the threaded connection tube 1031 to remove the dust cover 2 for cleaning, thereby preventing the waste lubricating oil from corroding the bearing and extending the service life of the bearing.

[0024] When lubricating the bearing, remove the plug 4 and inject lubricating oil into the area where the roller 104 is located through the oil injection hole 205 to lubricate it.
