Abstract
The utility model provides a simple structure a bearing frame labyrinth seals structure for install ball perpendicularly practical, sparingly cost, reduction trouble efficiency, it includes ball, its characterized in that: still rotate the bearing frame connected and respectively set up this bearing frame about last labyrinth ring both ends on and under labyrinth ring in the ball bottom and through the bearing rather than constituting including setting up, wherein go up labyrinth ring pass through locking screw fixed mounting in ball is last and go up and still to be provided with O type sealing washer between labyrinth ring and the ball, and it is provided with between terminal surface and the bearing frame up end down and is used for forming the clearance that contactless sealed up should to go up labyrinth ring, ball was in high -speed rotatory state during this kind of structural style's structure can be guaranteed to this scheme, also can effectually prevent that external cutting fluid and the lubricating oil on the roller lead screw can be inside ball enter into the bearing frame simultaneously.
Description
Technical field
The utility model relates to numerical control machine tool technique field, refers more particularly to a kind of bearing support labyrinth seal structure at right angle setting ball screw.
Background technique
Gap is there is between labyrinth ring in traditional ball screw bearing support and bearing, when ball screw at right angle setting, extraneous cutting fluid and the lubricant oil of ball screw can enter into bearing support inside along ball screw, the dilution of the lubricating grease of Bearing inner is flowed out, cause bearing lubrication to lose efficacy, accelerate bearing wear.In view of this, for how to search out a kind of simple and practical, save cost, reduce fault efficiency just seem particularly important for the labyrinth seal structure installing ball screw bearing support.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple and practical, bearing support labyrinth seal structure at right angle setting ball screw of saving cost, reducing fault efficiency.
For achieving the above object, technological scheme provided by the utility model is: a kind of bearing support labyrinth seal structure at right angle setting ball screw, comprise ball screw, it is characterized in that: also comprise and be arranged at ball screw bottom and the bearing support be rotationally connected by bearing and its formation and the upper labyrinth ring be separately positioned on the upper and lower two ends of this bearing support and lower labyrinth ring, wherein said upper labyrinth ring to be fixedly installed on described ball screw by lock screw and to be also provided with 0 RunddichtringO between upper labyrinth ring and ball screw, this is provided with the gap sealed for the formation of non-contact type between its lower end surface of labyrinth ring and bearing support upper-end surface.
Preferably, described lower labyrinth ring is formed by the bearing gland and bearing support being positioned at bearing support bottom and is tightly connected.
Preferably, the annular groove that described upper labyrinth ring is provided with by its bottom and the annular boss Spielpassung that bearing support upper-end surface is provided with, realize labyrinth seal.
This programme is arranged at ball screw bottom and the bearing support be rotationally connected by bearing and its formation and the upper labyrinth ring be separately positioned on the upper and lower two ends of this bearing support and lower labyrinth ring by adopting to comprise, wherein go up labyrinth ring to be fixedly installed on ball screw by lock screw and to be also provided with 0 RunddichtringO between upper labyrinth ring and ball screw, this is provided with the structural type in the gap sealed for the formation of non-contact type between its lower end surface of labyrinth ring and bearing support upper-end surface, can ensure that in the structure of this kind of structural type, ball screw is in High Rotation Speed state, also can effectively prevent the lubricant oil on extraneous cutting fluid and ball screw from can enter into bearing support inside along ball screw simultaneously.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
Fig. 2 is the A place partial enlargement structural representation in Fig. 1.
In figure: 1-ball screw, the upper labyrinth ring of 2-, 3-lock screw, 4-O RunddichtringO, 5-bearing support, 6-bearing, 7-bearing gland, labyrinth ring under 8-, 9-gap.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail:
Shown in accompanying drawing 1 to 2, a kind of bearing support labyrinth seal structure at right angle setting ball screw described in the present embodiment, it comprises ball screw 1, be arranged at ball screw 1 bottom and the bearing support 5 be rotationally connected by bearing 6 and its formation and the upper labyrinth ring 2 be separately positioned on these bearing support about 5 two ends and lower labyrinth ring 8, wherein go up labyrinth ring 2 to be fixedly installed on ball screw 1 by lock screw 3 and between upper labyrinth ring 2 and ball screw 1, to be also provided with 0 RunddichtringO 4, this is provided with the gap 9 sealed for the formation of non-contact type between its lower end surface of labyrinth ring 2 and bearing support 5 upper-end surface.
Inner in order to prevent the lubricant oil on extraneous cutting fluid and ball screw from can enter into bearing support 5 along ball screw 1 further, above-mentioned lower labyrinth ring 8 is formed by the bearing gland 7 and bearing support 5 being positioned at bearing support 5 bottom and is tightly connected.
In order to make the linkage structure between upper labyrinth ring 2 and bearing support 5 become more simple, preferably going up annular groove that labyrinth ring 2 is provided with by its bottom and the annular boss Spielpassung that bearing support 5 upper-end surface is provided with in this programme, realizing labyrinth seal.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
