Abstract
The utility model relates to a bearing structure for a high-voltage explosion suppression type motor. The bearing structure comprises a bearing I, a bearing II, a bearing sleeve, a shaft, an inner oil storage ring and an outer oil storage ring. The width of the inner oil storage ring is identical to that of the outer oil storage ring, the inner oil storage ring and the outer oil storage ring are arranged between the bearing I and the bearing II, the inner diameter of the inner oil storage ring is matched with that of the shaft, the outer diameter of the outer oil storage ring is matched with the inner diameter of the bearing sleeve, and an annular channel formed between the outer surface of the inner oil storage ring and the inner surface of the outer oil storage ring is an oil storage space. Due to the inner oil storage ring and the outer oil storage ring additionally arranged between the two bearings, the oil storage space is increased. Additionally, an annular groove and a protruding ring matched with each other are arranged between a bearing outer cover and a locking nut, and a V-shaped sealing ring and a water blocking ring are eliminated, so that bearing temperature and mechanical loss are reduced. Seam allowance is designed between the bearing sleeve and a bearing inner cover for explosion suppression, and explosion suppression performance is improved.
Description
Technical field
The utility model relates to a kind of high voltage flameproof motor and uses bearing arrangement.
Background technology
At present, domestic high-voltage explosion-proof motor bearings structure usually needs two bearings near installation, and two few near oil reserve between the bearing of installing, and causes the motor filling cycle short; In addition, the bearing oil scraper ring is outer, and because manufacture deviation, bearing is difficult to tighten fully by the collar chucking, is prone to cause bearing loosening; Bearing outer ring does not apply axial pretightening, causes the bearing abnormal sound easily, increases ambient noise; Secondly, in order to ensure sealing, the bearing end cover side is provided with v-ring,
V-ring rubs with drip ring on being installed in axle mutually, and mechanical loss increases, and causes bearing temperature high; In addition, internal bearing cover and bearing holder (housing, cover) adopt the plane flame proof, and the flame proof reliability is lower.
The utility model content
The purpose of the utility model is to overcome above-mentioned shortcoming, provide a kind of safe and reliable, oil reserve fully, bearing shaft uses bearing arrangement to a kind of high voltage flameproof motor that pretension is arranged.
This to achieve these goals; The technical scheme that the utility model adopted is: it comprises bearing I, bearing II, bearing holder (housing, cover), axle; Oil storage ring and outer oil storage ring in also comprising; The oil storage ring is consistent with the width of outer oil storage ring in said, and interior oil storage ring and outer oil storage ring are located between bearing I and the bearing II, and the internal diameter of interior oil storage ring is complementary with axle; The external diameter of outer oil storage ring and the internal diameter of bearing holder (housing, cover) are complementary, and form the circular passage oil storage space between the inner surface of the outer surface of interior oil storage ring and outer oil storage ring.
In order to ensure the bearing chucking, also comprise stop washer and locking nut, said stop washer is located at the bearing oil scraper ring outside, and locking nut is located at the outside of stop washer.
In order to ensure the axial pretightening of bearing, also comprise preloading spring, said preloading spring is located between internal bearing cover and the bearing outer ring in the inner part.
For anti-sealing enters in the bearing bore, the outside of said locking nut is provided with bulge loop, is provided with in the bearing end cover inboard and the bulge loop annular groove that is complementary.
In order to improve explosion-proof performance, said bearing holder (housing, cover) inner side end is provided with the installation seam, and internal bearing cover is provided with and installs the installed surface that seam is complementary.
The effect of the utility model is and since between two bearings, set up interior oil storage ring with outside the oil storage ring, thereby increased oil storage space; Thereby compress stop washer in the bearing oil scraper ring outside through locking nut and reach the purpose that prevents that bearing is loosening; Between internal bearing cover and bearing outer ring in the inner part, thereby the purpose that preloading spring reaches the bearing axial pretightening is set; Between bearing end cover and locking nut, be provided with the annular groove and the bulge loop that are complementary, cancelled V-seal ring and drip ring, reduced bearing temperature and mechanical loss; Bearing holder (housing, cover) and internal bearing cover are designed to the seam flame proof, have improved explosion insulation performance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with embodiment the utility model is further specified.
With reference to accompanying drawing; It comprises cylindrical bearing 7, deep groove ball bearing 10, bearing holder (housing, cover) 6, axle 14, interior oil storage ring 9, outer oil storage ring 8, stop washer 3, locking nut 2, preloading spring 13; Interior oil storage ring 9 is consistent with the width of outer oil storage ring 8; Interior oil storage ring 9 and outer oil storage ring 8 are located between cylindrical bearing 7 and the deep groove ball bearing 10; The internal diameter of interior oil storage ring 9 is complementary with axle 14, and the internal diameter of the external diameter of outer oil storage ring 8 and bearing holder (housing, cover) 6 is complementary, and the circular passage that forms between the inner surface of the outer surface of interior oil storage ring 9 and outer oil storage ring 8 is an oil storage space; Stop washer 3 is located at bearing oil scraper ring 5 outsides, and locking nut 2 is located at the outside of stop washer 3; Preloading spring 13 is located between internal bearing cover 11 and 10 outer rings of deep groove ball bearing in the inner part; Bearing end cover 1 inboard is provided with annular groove, is provided with the bulge loop that is complementary with annular groove in the outside of locking nut 2.The inner side end of bearing holder (housing, cover) 6 is provided with the installation seam, and internal bearing cover 11 is provided with and installs the installed surface that seam is complementary.
Since between cylindrical bearing 7, deep groove ball bearing 10, set up interior oil storage ring 9 and outside oil storage ring 8, thereby increased oil storage space, prolonged from the cycle of oil fuel tube 4 oilings; Thereby compress stop washer 3 in bearing oil scraper ring 5 outsides through locking nut 2 and reach the purpose that prevents that bearing is loosening; Between internal bearing cover 11 and 10 outer rings of deep groove ball bearing in the inner part, thereby the purpose that preloading spring 13 reaches the bearing axial pretightening is set; Between bearing end cover 1 and locking nut 2, be provided with annular groove and the bulge loop that is complementary; V-seal ring and drip ring have been cancelled; Extraneous water must pass through concavo-convex circular passage when getting into bearing bore, thereby guarantees that shipwreck is to get in the bearing bore, in addition; Even there is water to enter in the bearing bore, also can discharge through the oil exit pipe 12 that is located at bearing end cover 1 bottom.Bearing holder (housing, cover) 6 is designed to the seam flame proof with internal bearing cover 11, has improved explosion insulation performance.
