Problems solved by technology

Because dust, water vapor and corrosive gas are pervasive, when the sealed bearing is used for a long time, dust, water vapor or corrosive gas can still invade the rolling body of the bearing, and the inlaid sealing ring cannot protect the rolling body of the bearing. Thorough sealing will affect the service life of the bearing. Once the bearing is short of oil or damaged, it cannot be refueled or repaired

Embodiment 1

[0017] Embodiment 1: The magnetic seal has a circular base 2 with a magnet 1 on the base 2 .

[0018] There is a shaft hole at the center of the base body 2; there is a transition body between the shaft hole of the base body 2 and the magnet 1, and the transition body is corrugated. The magnet is in the form of a ring and is located on the edge of the substrate; the magnet is inlaid on the substrate. The bearing has an outer ring 3, an inner ring 5, rolling elements 4 and a cage 6, and the magnet 1 is attracted to the outer ring 3 of the bearing.

[0019] When in use, the central shaft does not move, and the outer ring of the bearing rotates together with the rotating object. Since the inner hole of the magnetic seal is bundled on the shaft and fits tightly with the shaft, no relative movement occurs. The outer ring of the magnetic seal is in contact with the bearing under the action of magnetic force The outer ring is tightly fitted, and the base of the magnetic seal is made...

Embodiment 2

[0020] Embodiment 2: The base body 2 is a whole body, and the magnet 1 is a ring, located on the edge of the base body; the magnet is embedded on the base body. Others are the same as embodiment 1, omitted.

Embodiment 3

[0021] Embodiment 3: There is a shaft hole at the center of the base body 2, and the magnet 1 is ring-shaped and integrated with the base body. Others are the same as embodiment 1, omitted.

Abstract

Present invention refers to a magnetism sealing. Said magnetism sealing has a round basal body with magnet, said magnetism sealed basal body made of flexibility material, capable of automatically compensating automatically compensating magnetic sealed surface wearing, automatically eliminating shaft run-out axial float influence to magnetic sealed surface, said magnetism seal structure having fine sealing effect prolonging bearing service life, greatly raising production efficiency and reducing production costs.

Description

technical field [0001] The invention relates to a seal, especially a magnetic seal. Background technique [0002] At present, people generally use bearings to slow down and reduce friction on rotating objects, so as to improve work efficiency. The bearing is composed of inner ring, outer ring, rolling body and cage. When the bearing is used in a harsh working environment, the rolling body in the bearing is easily damaged. After the rolling body is damaged, the bearing loses its function . In order to prevent damage to the rolling elements, people generally use a sealing ring to be embedded in the gap between the inner ring and the outer ring to seal the gap between the inner ring and the outer ring. Because dust, water vapor and corrosive gas are pervasive, when the sealed bearing is used for a long time, dust, water vapor or corrosive gas can still invade the rolling body of the bearing, and the inlaid sealing ring cannot protect the rollin...
