In order to solve the technical problem that a bearing is stressed and damaged due to the external force, the invention discloses a protection structure of a motor bearing, wherein a taper hole is arranged at the end part of a rotor spindle, a screwed hole is arranged in an external rear bearing cover, a support shaft is also arranged, one end of the support shaft is a conical surface, the other end of the support shaft is provided with threads, the conical surface of the support shaft is matched with the taper hole, the threads are screwed into the screwed hole, and an O-sealing ring 3 is arranged at the back side of the conical surface. The invention provides the structure which can effectively protect the bearing, the motor bearing can be effectively protected, the bearing is prevented from being damaged when a motor is installed, and the motor is also prevented from being further damaged due to the damaged bearing.
Description
Technical field
The present invention relates to the plant equipment field, is a kind of bearing of motor protection structure specifically.
Background technology
Motor in transportation and storage process and with coal mine under matched unit dock when installation, bearing all receives external force, said external force usually makes the shaft strength damage.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of structure that bearing is effectively protected, can effectively protect bearing of motor, prevent because the bigger infringement that the bearing breakage causes motor.Concrete scheme is following:
A kind of bearing of motor protection structure is characterized in that: a taper hole 10 is set in the end of rotor axis of electric 11, a screwed hole 12 is set on the rear bearing enclosing cover 2; A back shaft 6 also is set; One end of said bolster 6 is the conical surface 13, and an other end is provided with screw thread 14, and said back shaft 6 conical surfaces 13 match with taper hole 10; Said screw thread 14 screws in the screwed hole 12, and the back side of the said conical surface 13 is provided with O-ring seals 3.
For guaranteeing the fixing of bolster 6 and rear bearing enclosing cover 2, the present invention also is provided with locking nut 5, and said locking nut 5 is used for locking said screw thread 14 in screwed hole 12.
For preventing the rotation of locking nut 5, the present invention also is provided with torsional stop 1, and torsional stop 1 is fixed on the rear bearing enclosing cover 2 through carrying bolt 7, nut 8 and packing ring 9, the locking hole 20 that the mid portion setting of said torsional stop 1 and locking nut profile are complementary.
In order to judge which kind of state back shaft 6 conical surfaces 13 are in motor shaft taper hole 10, and the present invention is provided with gag lever post 4, and said gag lever post 4 is arranged on the outer end of back shaft 6.
Advantage of the present invention is:
A kind of bearing of motor protection structure is set at motor rear bearing enclosing cover place; To prevent that motor shaft from taking place axially and radial motion in the bearing clearance; Thereby avoid static vibrations that bearing is caused damage; Can effectively protect bearing of motor, prevent because the bigger infringement that the bearing breakage causes motor.

Embodiment
Specify the present invention below in conjunction with accompanying drawing, like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, in the end of rotor axis of electric 11 taper hole 10 is set, a screwed hole 12 is set on the rear bearing enclosing cover 2, rear bearing enclosing cover 2 is as shown in Figure 4; It is as shown in Figure 3 that a back shaft 6 also is set, and an end of said bolster 6 is the conical surface 13, and an other end is a screw thread 14, and said back shaft 6 conical surfaces 13 match with taper hole 10, and said screw thread 14 screws in the screwed hole 12, and the back side of the said conical surface 13 is provided with O-ring seals 3.
For guaranteeing the fixing of bolster 6 and rear bearing enclosing cover 2, the present invention also is provided with locking nut 5, and said locking nut 5 is used for locking said screw thread 14 in screwed hole 12.
For preventing the rotation of locking nut 5; The present invention also is provided with torsional stop 1; Torsional stop 1 is as shown in Figure 5, and torsional stop 1 is fixed on the rear bearing enclosing cover 2 through carrying bolt 7, nut 8 and packing ring 9, the locking hole 20 that the mid portion setting of said torsional stop 1 and locking nut profile are complementary.
In order to judge which kind of state back shaft 6 conical surfaces 13 are in motor shaft taper hole 10, and the present invention is provided with gag lever post 4, and said gag lever post 4 is arranged on the outer end of back shaft 6.
Principle of the present invention is: when docking in transportation and with unit, the conical surface 13 is in engagement with taper hole 10, and is as shown in Figure 1: clockwise rotate back shaft 6 and can compress taper hole 10 up to its conical surface 13, the locking bearing.Clockwise rotate nut 5; With nut 5 back shaft 6 is locked; In order to prevent that nut 5 from rotating, a torsional stop 1 is installed again on rear bearing enclosing cover 2, torsional stop 1 is fixed on the rear bearing enclosing cover 2 through carrying bolt 7, nut 8 and packing ring 9; In order to seal, O-ring seals 3 has been installed on back shaft 6; During user's actuating motor, must make back shaft 6 conical surfaces 13 be in disengaged position with motor shaft taper hole 10, as shown in Figure 2; Take off gag lever post 4, unclamp nut 8, packing ring 9, take off torsional stop 1; Unscrew nut 5 counterclockwise; Unscrew back shaft 6 counterclockwise, the taper hole 10 that makes back shaft 6 conical surfaces 13 break away from machine shaft 11 ends moves to the inwall that O-ring seals 3 is adjacent to rear bearing enclosing cover 2.Fastening nut 5 is installed in torsional stop 1, nut 8, packing ring 9, gag lever post 4 on the motor clockwise.In order to judge which kind of state back shaft 6 conical surfaces 13 are in motor shaft taper hole 10, and a gag lever post 4 has been installed, if gag lever post 4 is adjacent to rear bearing enclosing cover 2, then back shaft 6 is in engagement with taper hole 10 on back shaft 6; If gag lever post 4 has certain distance with rear bearing enclosing cover 2, then back shaft 6 is in disengaged position with taper hole 10.
