Abstract
The utility model relates to a locking nut structure for a ball high-speed mechanical main shaft, and is particularly used for bearing locking for a high-precision, high-speed mechanical main shaft. A labyrinth seal hole (5) is arranged on an annular step of a nut main body (8), the shape of an inner cavity matching hole (6) of the nut main body (8) is matched with a rotation shaft, at least two screw holes (2) for containing locking screws (3) are uniformly distributed on the area of a main screw hole (1) on the inner wall of the upper half part of the nut main body (8), a locking block (4) is arranged on the front end of each locking screw (3); and at least two spanner holes (7) are uniformly formed on the outer wall of the nut main body (8). For the locking nut structure, the cooperation degree with the rotation shaft of the main shaft is high, the structural symmetry is good, the bearing-locking performance is high, the locking nut structure is suitable for high-speed rotation, the structure is simple and subtle, the anti-loosing performance is high, the structure has a labyrinth sealing performance, the dust-proof performance is good and the locking nut structure is conveniently popularized and applied.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind ofly is used for bearing locking high-precision, the high speed machine main shaft.
Background technique
In the existing technology, the locking nut complex structure of main shaft, so that low with main shaft rotating shaft degree of adaptability, and structural symmetry is poor, is not suitable for high speed rotating, and in addition, dustproof effect is undesirable, needs often cleaning, uses inconvenient.
Summary of the invention
The utility model relates to a kind of locking nut structure of ball high speed machine main shaft, and it has overcome deficiency of the prior art.
The utility model technical solution is that it includes nut main body (8); The utility model is provided with labyrinth seal hole (5) particularly in the ring-shaped step of nut body (8); Inner chamber matching hole (6) shape of nut main body (8) matches with rotating shaft; The zone, main thread hole (1) of nut main body (8) upper half part inwall evenly is provided with at least two screw holes (2) of accommodating lock screw (3), and lock screw (3) front end is provided with locking block (4); Evenly have at least two driving holes (7) on the outer wall of nut main body (8).
During the utility model work, locking nut is enclosed within the bearing rotating shaft, matching hole is connected with the rotating shaft Spielpassung; Improve the quality of fit of locking nut, insert the driving hole rotation, after rotation puts in place with wrench; Tighten lock screw, the locking block collet threaded plays the effect of loosening, skid; Matching with the main shaft body in the labyrinth seal hole, utilizes labyrinth seal function to prevent that dust, foreign material from getting into main shaft inside.
The advantage of the utility model is:
1, this structure and main shaft rotating shaft degree of adaptability are high, and structural symmetry is good, and the locking bearing performance is high, is fit to high speed rotating;
2, the locking mechanism of this structure is simple, ingenious, and anti-loosening property is high;
3, this structure has labyrinth seal function, and anti-dust performance is good.
