Description

Technical Field

[0001] The utility model relates to the technical field of deep groove ball flange bearings, in particular to a deep groove ball flange bearing. Background Art

[0002] Deep groove ball flange bearings are a common rolling bearing used extensively in mechanical equipment. They can withstand radial loads and certain axial loads, making them suitable for a variety of operating environments. Their low friction, spherical rolling elements ensure low friction and smooth operation. Applications include motors (rotors and stators), household appliances (such as washing machines and fans), the automotive industry (wheel bearings and transmission systems), and industrial equipment (such as conveyors and processing machinery).

[0003] The current deep groove ball flange bearing is mainly composed of an outer ring, an inner ring installed in the outer ring, a cage installed between the inner ring and the outer ring, balls installed in the cage, and sealing covers installed on both sides of the inner ring and the outer ring. Although the deep groove ball flange bearing of this structure can use the sealing cover to seal and protect both sides of the bearing when in use, in order to avoid the sealing cover from hindering the relative rotation between the inner ring and the outer ring when the sealing cover is installed, it is necessary to reserve a layer of gap between the sealing cover and the inner wall of the outer ring. Due to the existence of this gap, some fine impurities will enter the deep groove ball flange bearing when in use, thereby increasing the friction inside the bearing and shortening the service life. At the same time, since the sealing cover is completely embedded between the outer ring and the inner ring after installation, and the outer side of the sealing cover is a smooth plane structure, the sealing cover is relatively unchanged when disassembled in the later stage, which makes it inconvenient to carry out efficient inspection and maintenance of the bearing.

[0013] By adopting the above technical solution, external lubricating oil can be conveniently injected into the space where the ball 1 and the ball 2 are located through the oil filling hole, so as to lubricate the ball 1 and the ball 2.

[0014] Furthermore, the contact parts between the outer ring and the ball 1 and the ball 2 are all concave structures, and the outer ring and the inner ring are both stainless steel rings.

[0015] By adopting the above technical solution, the rigidity of the inner ring and the outer ring can be effectively ensured.

[0016] Furthermore, the sealing cover is an annular structure, and the sealing cover is plugged into the inner ring.
