Problems solved by technology

[0002] As we all know, the dustproof and water release in the existing market is mainly realized by sealing rings and sealing rings and other components, but its reliability is low, the service life is short, and the friction performance is poor. With the development of science and technology, in some high temperature, high pressure and high speed In the running occasion, the structure of the seal ring and the seal ring is gradually replaced by the mechanical seal, but in the mechanical field, such as the operation of the CNC lathe, air guns or high-pressure and large-flow coolant are often used. When the structure of the mechanical seal is unreasonable In some cases, the air gun or coolant is easy to blow dust or water into the interior of the spindle, which will affect the service life of the spindle

Abstract

The invention discloses a dustproof and waterproof sealing structure for a mechanical spindle and belongs to the technical field of machinery. The dustproof and waterproof sealing structure comprises a shell, a spindle is arranged in the shell, a front end cap is arranged on the front end face of the shell, a dustproof cover is fixedly arranged on the spindle, a first clearance exists between the dustproof cover and the front end cap in a matched manner, a centrifugal groove is formed in the inner end face of the dustproof cover, and a flow reversing structure is arranged on the spindle; a spindle step is arranged on the spindle, the flow reversing structure mainly comprises a groove formed in the outer side face of the spindle step, the groove is positioned on an inner-end extension line of the first clearance, a flow blocking structure is arranged between the spindle and the front end cap and composed of an inner step, an outer step and the spindle step, the spindle step is positioned between the inner step and the outer step, and the inner step is higher than the outer step. A diversion structure and three sealing structures are provided, a mechanical seal is stable in sealing state during long-period running, high in reliability, free of friction and long in service life.

Description

technical field [0001] The invention belongs to the technical field of machinery, and refers to a dustproof and waterproof sealing structure of a mechanical main shaft. Background technique [0002] As we all know, the dustproof and water release in the existing market is mainly realized by sealing rings and sealing rings and other components, but its reliability is low, the service life is short, and the friction performance is poor. With the development of science and technology, in some high temperature, high pressure and high speed In the running occasion, the structure of the seal ring and the seal ring is gradually replaced by the mechanical seal, but in the mechanical field, such as the operation of the CNC lathe, air guns or high-pressure and large-flow coolant are often used. When the structure of the mechanical seal is unreasonable Under normal circumstances, the air gun or coolant is easy to blow dust or water into the interior of the spindle, which will affect th...
