Deep groove ball bearing with mute function

Abstract

The utility model discloses a deep groove ball bearing with a mute function, which belongs to the technical field of deep groove ball bearings, and comprises a bearing body, an inner ring is arranged in the bearing body, a lubricating device is arranged in the bearing body, a feeding hole is formed in the lubricating device, a shielding device is arranged outside the feeding hole in an outside clamping manner, and the inner ring is arranged in the bearing body. The lubricating device comprises two sealing rings, and a shell is connected to the lower portions of the sealing rings. According to the deep groove ball bearing with the mute function, the sealing ring, the shell, the through hole, the funnel, the sponge block and the smearing brush are arranged, the sponge block sucks lubricating oil, then the lubricating oil flows to the smearing brush, at the moment, when the bearing is rotated, the smearing brush can lubricate the interior of the bearing, and the situation that a modern bearing is usually provided with a sealing device to prevent dust from invading is avoided; this makes the lubrication work complex and inconvenient, and in addition, conventional lubrication methods may need to stop the operation of the bearing, which increases the complexity of maintenance and the possibility of production interruption.
