[0002] Bearings play an important role in mechanical transmission. Bearings are used to support rotating shafts or rotating bodies. High-speed equipment or machinery often requires precision bearings for support. Existing high-speed precision bearings may cause bolts to loosen due to rotation and vibration during use, resulting in grease leakage. At the same time, long-term use will cause the bearing temperature to be high. If the temperature is too high, it is easy to cause bearing damage and affect the use of equipment or machinery.

The sealing rings are fixed by a fixer, and the fixer is designed to enter the interior of the bearing shell. There are heat exchange boxes on both sides of the bearing shell. The heat exchange boxes are of a hollow design. A liquid inlet pipe connected by a flange is arranged above the heat exchange box. The liquid outlet pipe is connected to the lower part of the heat exchange box. The liquid inlet pipe is connected to a refrigerant or cooling water. The liquid outlet pipe recycles the refrigerant or cooling water. A plurality of circular grooves are provided on the inner side of the bearing shell. A plurality of spherical balls are installed on the outer surface of the bearing inner shell. The spherical balls are connected to the circular grooves. The spherical balls rotate freely in the circular grooves. The cavity of the bearing shell is filled with grease.

[0007] Preferably, the fixer includes a screw, a notch, an insert plate, and a nut. The screw passes through the sealing ring and is threadedly connected to the fixing block in the bearing housing. The fixing block is located on the inner wall of the bearing housing. A notch is provided at one end of the screw away from the bearing housing. A insert plate is installed in the notch. The insert plate is installed with a nut, and the nut is threadedly connected to the screw.
[0008] Compared with the prior art, the utility model has the following advantages: the utility model has a reasonable design; the first partition and the second partition in the heat exchange box extend the residence time of the refrigerant or cooling water in the heat exchange box, and the refrigerant or cooling water is used to accelerate the heat dissipation of the bearing; the fixing device fixes the sealing ring, and the notch and the insert plate on the fixing device contact the nut, thereby increasing the friction of the nut and reducing the loosening of the nut due to vibration or rotation, thereby avoiding the leakage of grease affecting the use of the bearing.
