Pressure transmission sealing coupler

Abstract

The invention discloses a pressure transmission sealing coupler. The coupler comprises a base in which an axial cavity is formed, wherein a rotating shaft which is provided with an input shaft interface and an output shaft interface passes through the axial cavity; the output shaft interface is positioned above the whole mechanism, and the input shaft interface is positioned below the whole mechanism; a bearing component and a base oil seal positioned above the bearing component are arranged between the rotating shaft and the base; and the base oil seal is provided with a waterproof pressure reducing sealing component which is compacted with the base oil seal, has an annular integral structure and is sleeved at the periphery of the rotating shaft and connected with the base. The waterproof pressure reducing sealing component is arranged, so that the bearing component in the coupler smoothly rotates and is prevented from being blocked, worn and burnt out even if the coupler works in an environment filled with particle impurities, and the service life of parts is prolonged; zero leakage is achieved, and the coupler has a good pressure reducing effect and a good axial movement prevention effect when working in a pressure transmission mode; and the coupler has a smart and compact structure and a wide application range, and can be applied to various shaft coupling occasions.

Description

Pressure type transmission seal coupling technical field The invention relates to a coupling, in particular to a pressure transmission coupling. Background technique In engineering production, the coupling is a common accessory that is widely used to connect the driving shaft and the driven shaft. It is generally provided with a driving shaft interface and a driven shaft interface, and then a bearing assembly and a sealing assembly are arranged between the two interfaces. However, ordinary couplings usually have a limited degree of sealing. During rotation, they are prone to jamming and water leakage due to the penetration of foreign impurities, resulting in severe wear and tear of bearings, oil seals and other accessories, and they have to be replaced. If the sealing effect is to be ensured, many components must be added oil seal, but it is often not possible due to the limitation of installation space; in addition, if the coupling adopts pressure transmission, it will p...

However, ordinary couplings usually have a limited degree of sealing. During rotation, they are prone to jamming and water leakage due to the penetration of foreign impurities, resulting in severe wear and tear of bearings, oil seals and other accessories, and they have to be replaced. If the sealing effect is to be ensured, many components must be added oil seal, but it is often not possible due to the limitation of installation space; in addition, if the coupling adopts pressure transmission, it will produce axial movement due to reciprocating axia
