Abstract
The utility model discloses a play device is prevented in outer lane location in big-and-middle-sized motor double sleeve bearing, include: the deep groove bearing comprises a bearing outer ring positioning ring and a bearing inner ring positioning ring, wherein the bearing outer ring positioning ring and the bearing inner ring positioning ring are arranged between the roller bearing and the deep groove bearing and are in the same plane. The utility model has the advantages of simple structure, can solve when the rotor takes place axial displacement, guarantee that relative position can not change between the interior outer lane of two sets of bearings, prevent that bearing holder atress operation from damaging to extension motor bearing operating cycle increases equipment reliability, and play device is prevented in the two sets of bearing of medium and large-scale motor outer lane location.
Description
Technical Field
The utility model relates to a large and medium-sized motor technical field, specific play device is prevented in big and medium-sized motor double jacket bearing inner and outer lane location that says so.
Background
In order to ensure the safety and stability of the motor under the operating condition of heavy load, the driving end usually adopts a mode of matching two sets of bearings, when in assembly, only a boss or a gasket is arranged between two sets of bearing inner rings for separation and positioning, no reliable positioning measure is arranged between two sets of bearing outer rings, once the load operating condition changes, the rotor generates axial displacement, the inner rings of the two sets of bearings are positioned by the boss, the relative position cannot change, the outer rings of the bearings do not change because of no positioning measure, the inner rings and the outer rings of the bearings are not positioned on the same plane, the bearing retainer and the track can operate under the condition of bearing axial pressure, and finally the retainer deforms and is broken, and the bearing is damaged.
Disclosure of Invention
An object of the utility model is to overcome prior art not enough, and provide one kind and can solve when the rotor takes place axial displacement, guarantee that relative position can not change between the interior outer lane of two sets of bearings, the interior outer lane of every set of bearing remains throughout at the coplanar, prevents that bearing holder atress operation from damaging to extension motor bearing operating cycle, increase equipment reliability, play device is prevented in the two sets of bearing of medium-size motor in the outer lane location.
In order to realize the aim, the utility model adopts the following technical scheme: the inner and outer ring positioning anti-channeling device for the double-sleeve bearing of a large and medium-sized motor comprises: the bearing inner ring positioning ring comprises a bearing outer ring positioning ring and a bearing inner ring positioning ring, wherein the outer diameter of the bearing outer ring positioning ring is 269.5mm, the wall thickness is 3mm, and the inner diameter is 227.5 mm; the inner diameter of the bearing inner ring positioning ring is 150.5mm, the outer diameter is 190.6mm, and the wall thickness is 3 mm; the bearing outer ring positioning ring and the bearing inner ring positioning ring are arranged between the roller bearing and the deep groove bearing and are in the same plane.
The installation step:
1. heating and installing the deep groove bearing to a fixed position;
2. placing a bearing inner ring positioning ring F to be tightly attached to the deep groove bearing inner ring D;
3. heating and installing the roller bearing inner ring B to a fixed position, and tightly attaching the roller bearing inner ring B to the bearing inner ring positioning ring F;
4. mounting the outer ring A of the roller bearing to a fixed position in a bearing chamber of a motor end cover;
5. placing a bearing outer ring positioning ring E in an end cover bearing chamber and tightly attaching to a roller bearing outer ring A;
6. mounting the bearing housing to a fixed position.
The utility model has the advantages of simple structure, can solve when the rotor takes place axial displacement, guarantee that relative position can not change between the interior outer lane of two sets of bearings, the interior outer lane of every set of bearing remains throughout at the coplanar, prevents that bearing holder atress operation from damaging to extension motor bearing operating cycle increases equipment reliability, and play device is prevented in the two sets of bearing inside and outside ring location of medium-size motor.

Detailed Description
The following description is provided to further explain the present invention with reference to the accompanying drawings.
The inner and outer ring positioning anti-channeling device for the double-sleeve bearing of a large and medium-sized motor comprises: bearing outer ring
The outer diameter of the bearing outer ring positioning ring is 269.5mm, the wall thickness is 3mm, and the inner diameter is 227.5 mm; the inner diameter of the bearing inner ring positioning ring is 150.5mm, the outer diameter is 190.6mm, and the wall thickness is 3 mm; the bearing outer ring positioning ring and the bearing inner ring positioning ring are arranged between the roller bearing and the deep groove bearing and are in the same plane.
The processing size precision of the inner ring and the outer ring of the bearing must meet the requirement, and friction is prevented from occurring in the operation. The bearing assembly is executed strictly according to the process standard, so that the positions of the two positioning circular rings are in the same plane after the bearing assembly is completed, and the two positioning circular rings can be firmly extruded by the two sets of bearings.
The scheme is a protection measure made according to the actual running condition and the overhaul condition of the field motor, the investment cost is low, the positioning protection of the large and medium-sized motor double-sleeve bearing can be realized only by processing two stainless steel rings, and the service life of the bearing is greatly prolonged.
