Abstract

A shaft sealer belongs to the technical field of mechanical engineering shafts. The shaft sealer comprises an inner ring I, a seal ring I, a seal ring II, an outer ring I, a seal ring III, an inner ring II, an outer ring II, a seal ring IV, a seal ring V and an inner ring III; the inner ring II and the inner ring III are arranged on the shaft table of the inner ring I, the seal ring I and the seal ring II are arranged in a groove at the shaft hole of the inner ring I, and the seal ring V is arranged in a groove between the inner ring I and the inner ring III; and the seal ring III is arranged in the groove of the outer ring I, and the seal ring IV is arranged in the groove of the outer ring II. The shaft sealer has the advantages that the installation is easy, no abrasion appears in the running process, damages are difficult, and the sealing effect is good.

Description

technical field [0001] The invention belongs to the technical field of shafts in mechanical engineering, in particular to a shaft sealer. Background technique [0002] In mechanical engineering, especially in machinery with a rotating shaft, thin oil is generally used to lubricate the gears and bearings in the box, and the rotating shaft is usually installed through the box. In order to prevent the lubricating oil from flowing out along the axial direction, various The sealing element for the seed shaft is installed at the end of the shaft hole of the casing. [0003] Shaft seals can be divided into two categories: contact seals and non-contact seals. Contact seals mainly include felt ring seals, expanding ring seals, and lip seals for rotating shafts. Since the shaft is in contact with the sealing ring when it rotates, the sealing ring will wear out over time, which will affect the sealing effect. The non-contact sealing ring is not worn when it works, and generally does ...
