Description

Technical Field

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

[0002] Deep groove ball bearing (GB / T 276—2003) formerly known as single-row radial ball bearing, is the most widely used rolling bearing, characterized by low friction resistance and high speed. It can be used on parts that bear radial load or combined load of radial and axial loads at the same time, and can also be used on parts that bear axial loads, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc. This type of deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of retaining frames. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is also divided into sealed and open structures. The open type means that the bearing is not With a sealing structure, the sealed deep groove ball is divided into dust-proof seal and oil-proof seal. The dust-proof seal cover is made of stamped steel plate and only plays a simple role in preventing dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing. When traditional bearings are working, the friction between the rolling elements and the outer ring causes wear on the inner wall of the outer ring during operation, which reduces the loss of the bearing during operation and is prone to noise. If other damaged sounds appear in the bearing, they cannot be discovered and checked, which reduces the convenience of the bearing operation. Therefore, a rolling deep groove ball bearing is proposed.

[0003] After searching, the patent announcement number CN210423453U discloses a dustproof rolling deep groove ball bearing, including a bearing outer ring and a bearing inner ring, each of the mounting grooves is provided with a card slot connected to a first threaded hole on the inner side, the front and rear surfaces of the bearing outer ring are provided with dustproof sealing grooves, each of the dustproof sealing grooves is provided with a dustproof sealing ring inside, a dustproof plate is provided on one side of the dustproof sealing ring, a connecting block matching the mounting groove is symmetrically provided on one side of the dustproof plate, a card block matching the card slot is provided on one side of the connecting block, and a second threaded hole is provided on one side of the card block , the other side of the dustproof plate is symmetrically provided with fixing bolts matching the first threaded hole and the second threaded hole. However, when the bearing is working in the prior art document, due to the friction between the rolling element and the outer ring, the inner wall of the outer ring is worn during operation, which reduces the loss of the bearing during operation and is prone to noise. If other damaged sounds appear in the bearing, they cannot be found and checked, which reduces the convenience of the bearing operation. Moreover, in the prior art document, the rolling element of the bearing does not rub against the outer ring during operation, and the high temperature generated by the friction is easy to damage the rolling element, thereby reducing the service life of the rolling element.

[0015] By arranging a slot around the holder, the holder and the slot can be used in combination to limit the rolling body. Then, through the action of the high-temperature resistant layer, when the rolling body and the outer ring generate high temperature due to friction, the damage to the rolling body caused by the high temperature is reduced.

Then, the rolling body is isolated by the retaining frame, and the rolling body is usually guided and retained in the bearing. Through the coordinated use of the protective layer and the high-temperature resistant layer, the loss of the rolling body caused by friction when the bearing is working is reduced, thereby increasing the service life of the rolling element.
