Description
Technical field:
The utility model relates to mechanically-sealing apparatus, relates in particular to electric main shaft circular arc labyrinth gland.
Background technology:
The electricity main shaft is the high-speed, high precision machine tool functional component, in the lathe internal environment cutting fluid and cutting dust are arranged, environment is more abominable, once cutting fluid or cutting dust enter electric main shaft inside, will cause the damage of electric mainshaft bearing or electric spindle motor, influence the life-span of electric main shaft, serious meeting causes the damage of electric main shaft.Because of electric main shaft is a high-speed rotary part, the contact sealing generally is not suitable for electric main shaft, electric main shaft sealing is mostly selected gap labyrinth sealing mode for use, the labyrinth seal structure of prior art is a linear pattern all, in case foreign material enter the labyrinth, is difficult to throw away, cause cumulative, advance darker and darker, finally enter electric main shaft inside, and cause the damage of electric main shaft by the labyrinth.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of electric main shaft circular arc labyrinth gland is provided, and adopts circular arc labyrinth sealing, the useful life of improving electric main shaft.
Electric main shaft circular arc labyrinth gland described in the utility model includes main shaft, turning labyrinth sealing ring, fixedly labyrinth seal ring, bearing, front end housing, shell, motor stator, rotor, bonnet and aviation plug are formed.Said main shaft is a central part of the present utility model, is arranged on center of the present utility model, is provided with shell at outermost of the present utility model.Between shell and main shaft, also be whole in position placed in the middle substantially, be provided with motor stator and rotor, said rotor is arranged on the position near main shaft, and motor stator then is arranged between shell and the rotor.In the rear end of main shaft, also be rear end at shell, be provided with bonnet, the rearward end of main shaft is covered in the bonnet, the outer end of bonnet is provided with aviation plug.The front end of shell is connected with front end housing, is provided with bearing between front end housing and the main shaft.The front end of main shaft stretches out outside front end housing, on the front end of front end housing, is provided with fixedly labyrinth seal ring, between said fixedly labyrinth seal ring and main shaft, is provided with the turning labyrinth sealing ring.By the turning labyrinth sealing ring and fixedly labyrinth seal ring form the circular arc labyrinth seal, hermetically-sealed construction is that oblique line and circular arc are formed, inner diameter is less, the outer end size is big, enter sealing if any foreign material by the gap, when main axis rotation, can rely on the centrifugal force direction to throw away along tangent line the foreign material that enter the labyrinth effectively, simultaneously some ring shaped slots are arranged at fixing labyrinth seal ring cutting, prevent that foreign material from invading along the labyrinth wall, can prevent effectively that foreign material are cumulative, invade electric main shaft inside gradually, and cause damage main shaft.
Electric main shaft circular arc labyrinth gland described in the utility model, overall structure is simple, and is easy for operation, good stability, the reliability height can effectively avoid foreign material to enter the labyrinth, even there are foreign material to enter, also can under action of centrifugal force, be thrown out of, can guarantee the reliability of using along tangent line.
Description of drawings:
Accompanying drawing is an electric main shaft circular arc labyrinth gland structural representation described in the utility model.1-main shaft 2-turning labyrinth sealing ring 3-is labyrinth seal ring 4-bearing 5-front end housing 6-shell 7-motor stator 8-rotor 9-bonnet 10-aviation plug fixedly
Embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: electric main shaft circular arc labyrinth gland described in the utility model includes main shaft 1, turning labyrinth sealing ring 2, fixedly labyrinth seal ring 3, bearing 4, front end housing 5, shell 6, motor stator 7, rotor 8, bonnet 9 and aviation plug 10 are formed.Said main shaft 1 is a central part of the present utility model, is arranged on center of the present utility model, is provided with shell 6 at outermost of the present utility model.Between shell 6 and main shaft 1, also be whole in position placed in the middle substantially, be provided with motor stator 7 and rotor 8, said rotor 8 is arranged on the position near main shaft 1, and 7 of motor stators are arranged between shell 6 and the rotor 8.In the rear end of main shaft 1, also be in the rear end of shell 6, be provided with bonnet 9, the rearward end of main shaft 1 is covered in the bonnet 9, the outer end of bonnet 9 is provided with aviation plug 10.The front end of shell 6 is connected with front end housing 5, is provided with bearing 4 between front end housing 5 and the main shaft 1.The front end of main shaft 1 stretches out outside front end housing 5, on the front end of front end housing 5, is provided with fixedly labyrinth seal ring 3, between said fixedly labyrinth seal ring 3 and main shaft 1, is provided with turning labyrinth sealing ring 2.By turning labyrinth sealing ring 2 and fixedly labyrinth seal ring 3 form the circular arc labyrinth seal, hermetically-sealed construction is that oblique line and circular arc are formed, inner diameter is less, the outer end size is big, enter sealing if any foreign material by the gap, when main axis rotation, can rely on the centrifugal force direction to throw away along tangent line the foreign material that enter the labyrinth effectively, simultaneously some ring shaped slots are arranged at fixing labyrinth seal ring cutting, prevent that foreign material from invading along the labyrinth wall, can prevent effectively that foreign material are cumulative, invade electric main shaft inside gradually, and cause damage main shaft.Electric main shaft circular arc labyrinth gland described in the utility model, overall structure is simple, and is easy for operation, good stability, the reliability height can effectively avoid foreign material to enter the labyrinth, even there are foreign material to enter, also can under action of centrifugal force, be thrown out of, can guarantee the reliability of using along tangent line.
