Embodiment Construction

[0013] In order to further understand the high temperature resistant bearing and its sealing assembly, further description will be made in conjunction with the accompanying drawings.

[0014] High temperature resistant bearing and its sealing assembly, which includes: housing 1, shaft rubber body, dust-proof bearing 3 and sealing ring 2, dust-proof bearing 3 is installed between the housing 1 and the shaft rubber body, housing 1 and the shaft rubber The body is directly sealed as a whole. The top of the dustproof bearing 3 is provided with a sealing ring 2. The sealing ring 2 matches the outer diameter of the inner ring of the bearing. The sealing washer 4 of the current standard structure is removed. Diameter fit to achieve sealing, reduce the size and number of parts, that is, to achieve the role of high temperature resistant sealing, and reduce the volume and weight of the bearing.

Abstract

The invention belongs to the field of bearings, and relates to a bearing and a seal assembly thereof, in particular to a high-temperature bearing and a seal assembly thereof. The existing seal washer with a standard structure is removed, outside diameters of a seal ring and a bearing inner ring are matched to realize sealing, the dimensions and quantity of spare parts are reduced, the angle and elastic deformation of a seal lip are designed scientifically, the sealability is not reduced, and the friction is reduced.

Description

technical field [0001] The invention relates to a bearing and its sealing assembly, in particular to a high-temperature-resistant bearing and its sealing assembly, belonging to the field of bearings. Background technique [0002] Bearings for high-temperature rotating machinery such as automotive retarders and mining equipment have increasingly stringent requirements for high-temperature resistance and miniaturization. At present, the high-temperature resistant bearings commonly used in automobile retarders and mining equipment adopt the structure of bearings, sealing washers and sealing rings, which occupy a large space, the size of each part is large, and the number of parts is large; it is increasingly unable to meet the requirements of automobile retarding. The requirements for high temperature resistant bearings such as appliances and mining equipment. Contents of the invention [0003] In view of the problems existing in the prior art, the purpose of the present...
