Sealing and cooling structure of ultra-speed table

Abstract

The invention discloses a sealing and cooling structure of an ultra-speed table. The sealing and cooling structure is characterized in that a cover is fixedly connected onto a protective cover, the protective cover is fixedly connected with an upper port of a motor casing, a lower port of the motor casing is fixedly connected with an upper port of an upper wiring cover, a lower port of the upper wiring cover is fixedly connected with an upper port of a lower wiring cover, one end of a pipeline is hermetically connected with a lower port of the lower wiring cover, the other end of the pipelineis hermetically connected with an air outlet of an air blower, and a valve is connected onto the pipeline; spaces between the protective cover and the cover, between the protective cover and the motorcasing, between the motor casing and the upper wiring cover and between the upper wiring cover and the lower wiring cover are sealed by sealing rings. The sealing and cooling structure has the advantages that main units are integrally sealed instead of being originally locally sealed by sawtooth shaft peaks at the upper ends of rotors, accordingly, sealing modes are simple, and good sealing effects can be realized; the sealing and cooling structure can be in intermittent working and intermittent cooling schemes, and accordingly good cooling effects can be realized.

Description

Technical field: [0001] The invention relates to a sealing and cooling structure of an overspeed table. Background technique: [0002] The existing overspeed table adopts the shaft-peak sawtooth seal structure, the sealing effect is not very good, and the off-line sealing effect cannot be achieved, and the cooling measure of the overspeed table is to install a cooling fan 400 on the spindle at the lower end of the rotor, and install a cooling fan 400 on the motor casing. Ventilation holes 500 are arranged on the outer wall, and the cooling fan 400 forms convection with the ventilation holes 500, cooling while working, and the cooling effect is average. Invention content: [0003] The present invention provides a sealing and cooling structure of an overspeed table in order to solve the above-mentioned problems in the prior art. [0004] The technical solution adopted in the present invention includes: a sealing and cooling structure of an overspeed table, including a prote...
