Abstract
The invention relates to an oil-seepage-proof motor rotor shaft. One end of the rotor shaft extends into a motor and is fixedly connected with a motor rotor, and the other end of the rotor shaft is positioned outside the motor and immersed in lubricating oil of an engine cylinder body; a seal ring is arranged between the motor rotor shaft and a motor housing; a spiral oil preventing groove is formed in the rotor shaft outside the motor on the outer side of the position where the seal ring is mounted; and the rotational direction of the oil preventing groove is opposite to that of the rotor shaft. The oil-seepage-proof motor rotor shaft is simple in structure and good in manufacturability, meets the requirement of preventing the lubricating oil from seeping into the motor through simple means, ensures working reliability of the motor, and is remarkable in oil-seepage-proof effect.
Description
Technical field
The present invention relates to a kind of rotor axis of electric, especially a kind of motor for preventing oil impregnate armature spindle.
Background technology
No matter be the magneto of aero-engine or the separated motor of automobile engine, all be connected with the cylinder body of engine lubrication system, armature spindle external part is wherein immersed in the lubricating oil in cylinder body, although motor internal has installed the circle of obturaging preventing lubricating oil from entering interiors of products on armature spindle, but due to armature spindle smooth surface, lubricating oil very easily infiltrates interiors of products along smooth circular face, inner critical component---the platinum contact of the oil gas corrosion electrical motor that lubricating oil evaporation produces, make contact point surface corrosion, increase its sheet resistance, the energy that contact place is consumed increases, and then affect the reduction of magneto output energy, complete machine impotentia is even made to export, but also the lubricating oil accidental loss of engine system can be caused.
Summary of the invention
The object of this invention is to provide a kind of motor for preventing oil impregnate armature spindle, when the armature spindle of motor is immersed in lubricating oil, can prevent lubricating oil from penetrating into motor internal along the smooth surface of armature spindle, ensure the normal work of motor.
Technical scheme of the present invention is, described motor antiseepage armature spindle one end extend into motor internal and is connected with rotor, and the outside also immersion oil that the other end is arranged in motor, at the lubricating oil of engine cylinder-body, is provided with sealing ring between rotor axis of electric and electric machine casing; On the armature spindle of outside motor, be positioned at the position closing on sealing ring, be provided with a spiral anti-oil groove, the rotation direction of described anti-oil groove is contrary with armature spindle direction of rotation.The pitch of described anti-oil groove is 10mm, and cross section is circular arc, and radius is 1mm.
The present invention closes on position armature spindle installation sealing ring, design a spiral anti-oil groove, when rotor axis of electric rotates, the lubricating oil on armature spindle surface is collected in oil groove, because oil groove exists pitch, the centrifugal action that lubricating oil rotates at oil groove internal cause gravity and axle and glide along oil groove and be blocked in oil groove, lubricating oil is stopped and infiltrates in housing, reaches the object preventing lubricating oil from infiltrating motor internal; Carry out comprehensive consideration by the rotating speed of the concentration to armature spindle common used material and lipophile thereof, lubricating oil, working temperature, density and motor, by analysis and test, the parameter chosen can reach best grease proofing effect.Structure of the present invention is simple, good manufacturability, is reached the requirement preventing lubricating oil from infiltrating motor internal, ensure that the reliability of machine operation, seepage-proof oil successful by simple means.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in the figure, motor antiseepage armature spindle 1 one end extend into motor internal and is connected with rotor, and the outside also immersion oil that the other end is arranged in motor, at the lubricating oil of engine cylinder-body, is provided with sealing ring 3 between rotor axis of electric 1 and electric machine casing; On the armature spindle of outside motor, be positioned at the outside of installing sealing ring 3 position, be provided with a spiral anti-oil groove 2, the rotation direction of described anti-oil groove 2 is contrary with armature spindle direction of rotation.The pitch of described anti-oil groove 2 is 10mm, and cross section is circular arc, and radius is 1mm.
Claims (2)
1. a motor antiseepage armature spindle, it is characterized in that, described motor antiseepage armature spindle (1) one end extend into motor internal and is connected with rotor, the other end is arranged in the outside of motor and is immersed in the lubricating oil of engine cylinder-body, is provided with sealing ring (3) between rotor axis of electric (1) and electric machine casing; On the armature spindle of outside motor, be positioned at the outside of installing sealing ring (3) position, be provided with a spiral anti-oil groove (2), the rotation direction of described anti-oil groove (2) is contrary with armature spindle direction of rotation.
2. motor antiseepage armature spindle as claimed in claim 1, it is characterized in that, the pitch of described anti-oil groove (2) is 10mm, and cross section is circular arc, and radius is 1mm.
