Abstract
The utility model relates to a bearing outer ring gland for high-speed ball electric spindles, in particular to a bearing outer ring gland structure for machine tool high-speed ball electric spindles. An O-shaped seal ring 3 is arranged on the outer ring wall of a gland 2. The bottom of the gland 2 is provided with a bottom air inlet 6. The ring wall of the gland 2 is provided with an inner radial air inlet 7 communicated with the bottom air inlet 6. The front inner wall of the gland 2 at the radial through hole 7 is provided with a ring air groove 8 communicated with the radial air inlet 7. An inner sleeve 1 is provided with at least one inner wall air inlet 9 radially communicated with the ring air groove 8. The outer ring gland is multifunctional, high in airtightness, simple in structure, easy to process, capable of fully protecting the electric spindle, and convenient to popularize and apply.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind of outer race gland structure of using for mechanical processing machine ball high-speed electric main shaft.
Background technology
In the prior art, ball high-speed electric main shaft outer race gland function singleness, sealing is poor, complex structure, processing difficulties, not enough to electric main shaft protection, be not easy to promote and use.
Summary of the invention
For solving above-mentioned prior art deficiency, the utility model provides a kind of ball high-speed electric main shaft outer race gland.
The utility model technical solution is cover 1 in including, gland 2, soket head cap screw hole 4, screwed hole 5, the external annulus that it is characterized in that gland 2 is provided with O RunddichtringO 3, and the bottom of gland 2 is provided with bottom inflow hole 6, is provided with the radial air inlet hole 7 that communicates with bottom inflow hole 6 in the ring wall of gland 2, front end gland 2 inwalls in radial air inlet hole 7 are provided with the ring air drain 8 that communicates with it, and interior cover 1 is provided with and at least one the inwall air admission hole 9 that encircles that air drain 8 radially communicates.
Operation principle of the present utility model is: in put uniform several inwall air admission holes along the circumferential direction, radial air inlet hole on the gland, the bottom inflow hole, ring air drain etc. is fixed on the outer race gland on the bearing by the hex screw hole, by the fixing fastening outer race gland cover plate of screwed hole.Compressed Gas enters from the bottom inflow hole, enters the ring air drain through the radial air inlet hole again, enters interior cover by the inwall air admission hole then, and inwardly the endoporus of cover provides source of the gas, forms sealing gland, prevents that dust etc. from entering electric main shaft inside.
Advantage of the present utility model is:
1, leads to compressed air from the bottom inflow hole, discharge from the endoporus of interior cover, form sealing gland, prevent that dust etc. from entering electric main shaft inside, shields to electric main shaft;
2, the O RunddichtringO can prevent that Compressed Gas from leaking gas in the slit of outer race gland and bearing block, guarantees that gas all from the endoporus discharge of interior cover, has promoted sealing;
3, interior cover and gland adopt interference fit and gluing assembling, and processing is simple, good airproof performance;
4, the utility model is simple in structure, and is easy to use, can be widely used in various high-speed electric main shafts.
