Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to an anti-clogging deep groove ball bearing. Background Art

[0002] Bearings are common parts used in mechanical transmission. In mechanical transmission, they can reduce the friction coefficient during transmission and make mechanical transmission more stable. Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used rolling bearings. They are characterized by low friction resistance and high speed. They can be used on parts that bear radial loads or combined loads of radial and axial loads at the same time, and can also be used on parts that bear axial loads, such as low-power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

[0003] After installation, deep groove ball bearings are completely exposed to the outside. After long-term use, dust or other impurities may enter the lubrication between the rolling elements of the bearings. These dust or impurities are easily blocked in the clearance and other positions, which can easily cause the bearing to operate poorly. Generally, deep groove ball bearings prevent dust from entering by clamping a dust cover inside the outer ring. However, since the dust cover does not contact the inner ring, it cannot prevent fine dust or foreign matter, so it needs to be improved. Utility Model Content

Due to the excellent self-lubricating performance of the polytetrafluoroethylene ring 7, it can maintain a tight seal without affecting the rotation. When it is necessary to inject lubricating oil into the ball 4, inject the lubricating oil from the oil filling pipe 10, let the lubricating oil flow through the oil filling pipe 10 into the space between the retaining frame 3 and the ball 4 for lubrication, and at the same time prevent dust from entering during oil filling through the dust filter 15. After the oil filling is completed, the sealing plug 11 is threadedly connected to the inner wall of the oil filling pipe 10 by rotating the knob 14 for sealing. When the inner steel ring 2 rotates, it will drive the mounting ring 12 to rotate together, so that the bristles 13 on the mounting ring 12 will brush between the external dustproof sheet 6 and the sealing groove 8, thereby preventing dust from accumulating on the polytetrafluoroethylene ring 7 in the sealing groove 8.
