Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a bearing grinding wheel. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Grinding wheels are the most important type of grinding tools in grinding processing.

[0003] The existing patent (publication number: CN219131985U) discloses a novel self-aligning roller bearing grinding wheel, which includes a chassis, a grinding wheel body fixedly connected to the outside of the chassis, a chip removal groove is provided on the outside of the grinding wheel body, a clamping hole is provided under the grinding wheel body, a lap plate is fixedly connected to the outside of the chassis, a screw rod is clamped in the lap plate, and the screw rod is threadedly connected to the clamping hole. The novel self-aligning roller bearing grinding wheel can overlap the grinding wheel body above the lap plate by setting the chip removal groove, the clamping hole, the lap plate and the screw rod, and then connect the screw rod in the lap plate with the clamping hole. The grinding wheel can fix the grinding wheel body and the chassis to the same horizontal line through the clamping hole and the screw rod, and the slag generated during the processing of the self-aligning roller bearing can be removed through the chip removal groove, avoiding the possibility of the slag after grinding splashing around and causing damage to the self-aligning roller bearing, and effectively ensuring the applicability of the grinding wheel.

[0004] When the above-mentioned grinding wheel is actually used, heat dissipation is performed by setting heat dissipation holes. However, due to the intense friction between the grinding wheel and the workpiece during use, the grinding wheel is prone to rapid temperature rise and even deformation. Heat dissipation through the heat dissipation holes alone cannot meet the heat dissipation requirements, and it is also necessary to use it together with a cooling device, which is inconvenient. Therefore, a bearing grinding wheel is proposed. Utility Model Content

The rotating shaft 9 is rotated, and the rotating shaft 9 drives the sealing disk 8 to rotate, so that the through hole 10 on the sealing disk 8 corresponds to the liquid outlet 7. The external driving device drives the grinding wheel 2 to rotate and perform the grinding work.
