Abstract
The utility model belongs to technical field of bearings, proposes a kind of ball bearing spindle spiral-flow type waterproof and dustproof structure.The ball bearing spindle of proposition is arranged with spiral-flow type waterproof and dustproof structure in the working end of ball bearing spindle；Waterproof and dustproof structure has the fixation dustproof cover for being fixed on shell one end；There is gap between fixed dustproof cover and the shaft core of ball bearing spindle；It is provided with the rotation dustproof cover being nested in shaft core in the gap between fixed dustproof cover and shaft core；Rotating between dustproof cover and fixed dustproof cover has gap；Rotating has helicla flute on the periphery of dustproof cover；The gas channel passed through to air-flow is formed between helicla flute and the fixation dustproof cover.The utility model causes air flow through the gas channel between rotation dustproof cover and fixed dustproof cover by power caused by rotation and blows out, and the sundries such as coolant liquid, dust, iron filings for being generated when main shaft is worked prevent outside main shaft, improve the service life of main shaft.
Description
Technical field
The utility model belongs to ball bearing spindle technical field more particularly to a kind of ball bearing spindle spiral-flow type is anti-
Water dustproof construction.
Background technology
Ball bearing spindle will produce the sundries such as a large amount of dust, iron filings in process, simultaneously because ball bearing
Main shaft generates heat in process, needs to spray coolant liquid in the working end of main shaft, in order to prevent coolant liquid, dust, iron filings etc.
Sundries enters main inside, and most common way is to install fixed dustproof cover additional in main shaft working end in the prior art, and the fixation is dust-proof
The shell being nested with outside ball bearing spindle is placed on to be fixedly connected；There is gap between the fixation dustproof cover and the shaft core of main shaft,
While main shaft runs at high speed, the sundries such as coolant liquid, dust, iron filings can be entered by the gap between fixed dustproof cover and shaft core
In main shaft, the service life of main shaft is affected.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of ball bearing spindle spiral-flow type waterproof
Dustproof construction.
The utility model is to complete above-mentioned purpose to adopt the following technical scheme that：
A kind of ball bearing spindle spiral-flow type waterproof and dustproof structure, the waterproof and dustproof structure are arranged in ball bearing
The working end of main shaft；The waterproof and dustproof structure has the fixation dustproof cover for being fixed on shell one end；The fixed dustproof cover
There is gap between the shaft core of ball bearing spindle；It is provided with and is nested in the gap between fixed dustproof cover and shaft core
Rotation dustproof cover in shaft core；The rotation dustproof cover is fixedly connected with the shaft core, and being formed can be with shaft core rotation
Structure；There is gap between rotation dustproof cover and the fixation dustproof cover；It is described rotation dustproof cover inner face with
There is gap between the bearing of ball bearing spindle working end；There is helicla flute, and institute on the periphery of the rotation dustproof cover
The helicla flute stated is located at least on the periphery of the nearly outer end face of rotation dustproof cover；The helicla flute and the fixation dustproof cover
Between form the gas channel that is passed through to air-flow.
The rotation dustproof cover is the ladder shaft-like being made of the cylinder of two sections of different-diameters；Rotate dustproof cover diameter compared with
Big cylindrical section is located at the outside of the smaller cylindrical section of diameter；The helicla flute is located at rotation dustproof cover and is relatively large in diameter the outer of cylindrical section
On disc.
The rotation dustproof cover is the ladder shaft-like being made of the cylinder of two sections of different-diameters；Rotate dustproof cover diameter compared with
Big cylindrical section is located at the outside of the smaller cylindrical section of diameter；The helicla flute is located on the periphery of entire rotation dustproof cover.
The rotation dustproof cover is bolted with the shaft core.
The rotation dustproof cover is interference fitted with the shaft core.
The utility model proposes a kind of ball bearing spindle spiral-flow type waterproof and dustproof structure, using in shaft core and fixation
The structure design of setting rotation dustproof cover between dustproof cover so that rotation dustproof cover with main shaft while rotating, by rotation
The gas channel that generated power causes air flow through between rotation dustproof cover and fixed dustproof cover is blown out, and is produced when main shaft is worked
The sundries such as raw coolant liquid, dust, iron filings prevent outside main shaft, improve the service life of main shaft.
