Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment components, in particular to a bearing dust cover for enhancing the heat dissipation of a bearing. Background Art

[0002] Bearings are key components widely used in mechanical equipment. Their operating stability and life directly affect the performance of the entire mechanical system. Under high-load and high-speed operating conditions, if the heat generated by the bearings cannot be dissipated in time, the temperature will rise, which will cause lubrication failure, increased wear and even damage. At the same time, dust and impurities in the external environment entering the bearings will also increase wear and shorten the bearing service life. In order to improve this phenomenon, it is particularly important to design a bearing dust cover that can enhance bearing heat dissipation.

[0003] Reference announcement number CN212377129U is a bearing dust cover, which includes a sealing ring with an annular groove at the upper end and an annular support plate arranged in the annular groove, and a retaining ring is provided at the lower end of the sealing ring; an annular sealing portion is provided radially inward on the inner wall of the sealing ring, and the upper end face of the annular sealing portion is an oblique annular surface three with an inner diameter gradually decreasing from top to bottom, and an annular protrusion is provided radially outward on the lower port of the annular sealing portion, and a buffer groove is formed between the annular protrusion and the retaining ring. The bearing dust cover is provided with a retaining ring for limiting and an annular sealing ring for sealing on the sealing ring. After the dust cover is closed on the bearing, the retaining ring is pressed against the inner wall of the bearing retainer, and the annular sealing portion and the annular protrusion thereon are pressed against the inner ring of the bearing. During this process, due to the existence of the buffer groove, the annular protrusion will be squeezed and deformed. After deformation, the contact area acting on the inner ring of the bearing will be increased, thereby improving the sealing effect. According to the above, although the bearing dust cover can be well applied, the heat dissipation performance of the bearing dust cover is usually average, making it difficult for the heat generated by the bearing to be quickly dissipated, and thus easily causing the bearing temperature to rise and damage, which often troubles users.
