Abstract
The utility model provides an external bearing seat of an explosion-proof vibration motor, and solves the problem that a motor bearing seat in the prior art with an internal bearing cover and a seat body in an integral structure results in the incapability of normal work of a motor because of the loosening of bolts. The external bearing seat includes a seat body, and an internal bearing cover and an external bearing cover arranged at the two ends of the seat body, the internal bearing cover and the seat body are in an integral structure, the internal bearing cover is provided with a blind screw hole, the external bearing cover and the internal bearing cover are fixedly connected through a bolt matched with the blind screw hole, and a loose-proofing gasket is arranged between the head of the bolt and the end cover of the external bearing. The external bearing seat is simple in structure and convenient for installation, and further guarantees the running safety of the explosion-proof motor.
Description
Technical field
The utility model relates to technical field of motors, particularly a kind of outer bearing carrier of explosion-proof shaking generator.
Background technology
The explosion-proof shaking generator vibration that will stand 1000 times (sextupole), 1500 times (four utmost points), 3000 times (the two poles of the earth) per minute, the parts of motor must guarantee at run duration not loosening.Grant number is the outer bearing carrier that the patent of CN201374603Y discloses a kind of explosion-proof shaking generator, this patent arranges integrative-structure by pedestal and inside cap, bearing holder (housing, cover) enters in pedestal, outside is fixed with outer bearing cover and bolt, make bearing card between pedestal and outer bearing cover, saved inside cap, the securing part quantity such as bolt, not only saved cost, and the outer bearing block of explosion-proof vibration motor of this structure can not cause explosion-proof shaking generator to damage phenomenon because of inside cap and set bolt loose or dislocation, thereby solved the problem of outer bearing block of explosion-proof vibration motor inside cap loose or dislocation.But, the explosion-proof shaking generator seat of this structure, although it is locking to use locking glue or locking spring washer to carry out in the threaded connection place of interior outer bearing, under motor is hot, bolt easily occurs to become flexible even to come off, and causes motor cisco unity malfunction.
Utility model content
The utility model provides a kind of outer bearing block of explosion-proof vibration motor, solves the motor bearing seat of existing inside cap and pedestal one because of the loosening problem that causes motor cisco unity malfunction of bolt generation,
The technical solution of the utility model is achieved in that a kind of outer bearing block of explosion-proof vibration motor, comprise pedestal and the inside cap and the outer bearing cover that are arranged at pedestal two ends, inside cap and pedestal are structure as a whole, inside cap is provided with not screw thoroughly, outer bearing cover by being fixedly connected with the bolt that screw does not match thoroughly, is equipped with lock washer between the head of bolt and outer bearing end cap with inside cap.
Wherein, preferably, lock washer is comprised of two packing rings, and the inner side of packing ring is pitch face, and the outside of packing ring is for becoming the repousse of interlocking pattern with two ends contact-making surface.
Wherein, preferably, the angle of the inclination of pitch face is greater than the angle of thread of bolt.
Wherein, preferably, one end of screw is not provided with screw thread surplus thoroughly.
Wherein, preferably, the thickness of screw thread surplus is at least the thickness of two times, packing ring.
The utility model inside cap and pedestal are structure as a whole, the securing part quantity such as inside cap, bolt have been saved, not only saved cost, and the outer bearing block of explosion-proof vibration motor of this structure can not cause because of inside cap and set bolt loose or dislocation explosion-proof shaking generator to damage phenomenon.And the bolt junction at inside cap and outer bearing cover, be provided with the lock washer being formed by two packing rings, when bolt looseness produces after certain moment of torsion, repousse frictional force is greater than the frictional force between the pitch face of inner side, thereby under this state, only allow the relative changing of the relative positions between the pitch face of inner side and produce lifting tension force, thereby can effectively solve the problem of bolt looseness.The utility model is simple in structure, easy for installation, further guarantees the fail safe of fire-proof motor operation.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A portion partial enlarged drawing of Fig. 1.
In figure, 1, pedestal, 2, inside cap, 3, outer bearing cover, 4, screw thread surplus, 5, bolt, 6, lock washer.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the present embodiment provides a kind of outer bearing block of explosion-proof vibration motor, comprise pedestal 1 and the inside cap 2 and the outer bearing cover 3 that are arranged at pedestal 1 two ends, inside cap 2 is structure as a whole with pedestal 1, inside cap 2 is provided with not screw thoroughly, outer bearing cover 3 by being fixedly connected with the bolt 5 that screw does not match thoroughly, is equipped with lock washer 6 between the head of bolt 5 and outer bearing end cap with inside cap 2.
Wherein, lock washer 6 is comprised of two packing rings, and the inner side of packing ring is pitch face, and the outside of packing ring is for to become the repousse of interlocking pattern with two ends contact-making surface, and the angle of the inclination of pitch face is greater than the angle of thread of bolt 5.Bolt 5 junctions at inside cap 2 and outer bearing cover 3, be provided with the lock washer 6 being formed by two packing rings, when bolt 5 is loosening, produce after certain moment of torsion, repousse frictional force is greater than the frictional force between the pitch face of inner side, thereby under this state, only allow the relative changing of the relative positions between the pitch face of inner side and produce lifting tension force, thereby can effectively solve the loosening problem of bolt 5.
And not thoroughly the other end of the corresponding lock washer 6 of screw be provided with screw thread surplus 4, the thickness of screw thread surplus 4 is at least the thickness of two times, packing ring.As occurred, lock washer 6 occurs that after damage or loss, rotatable bolt 5 makes it to tighten, and fixes inside cap 2 and outer bearing cover 3, has effectively guaranteed the fail safe of motor operation.
Wherein, the not saturating screw of inside cap 2 thickness is around not less than 3mm, and thickness is not less than 3mm, when motor internal has spark to blast, can make inside cap 2 bear certain pressure, has guaranteed the fail safe of motor.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
