Abstract
The utility model relates to a motor straightening bearing which is mainly composed of a straightening bearing inner ring 2, a straightening bearing outer ring 3 and a shape recovery stop jump ring 4. Through utilization of the shape recovery stop jump ring, thereby solving a wearing problem between the straightening bearing outer ring and a stator. A ceramic material is employed by the bearing to be a friction pair to prevent metal powder generated during running of a conventional bearing from affecting lubrication of a motor and performance of an electric appliance, thus improving the service life of the motor.
Description
Technical field
The utility model is a kind of alignment bearing for submersible electric machine with oil, belongs to petroleum machinery technical research field.
Background technology
Alignment bearing in the submersible electric machine with oil has the effect of righting, protection rotor joint, and existing alignment bearing adopts harder alloy to make the alignment bearing overcoat, does the alignment bearing inner sleeve with tin bronze.When submersible electric machine with oil turns round, can produce relative motion between alignment bearing cylindrical and the stator, thereby produce friction, the useful life of reducing bearing and stator; In the process of the Internal and external cycle of bearing friction, have in addition under a lot of metal dusts are ground, enter in the dynamo oil, affect greasy property and the electric property of motor, the useful life of having reduced motor.
Summary of the invention
This practical purpose is the problem that exists in order to overcome the said motor alignment bearing, has designed a kind of motor alignment bearing.
The purpose of this practical property is to realize by such technical scheme.
The motor alignment bearing is cylindrical, formed by alignment bearing outer ring, back-shaped stop jump ring, alignment bearing inner ring, the alignment bearing inner ring is by the ceramic material manufacturing, the ceramic coated material of alignment bearing inner surface, the alignment bearing inner ring is connected with key with motor shaft, the ceramic material of alignment bearing inner ring and alignment bearing outer ring consists of friction pair, ceramic material has high-wearing feature and non-conductive, magnetic conduction not, and the powder that enters lubricating oil during running reduces and powder can not affect the electric property of motor; The alignment bearing outer ring is provided with runner, can accelerate dynamo oil and flow, and accelerates the alignment bearing heat radiation; Back-shaped stop jump ring one end of bearing is connected with stator, and the other end is connected with the alignment bearing outer ring, stops to produce relative motion between the two.
Owing to having adopted technique scheme, the utlity model has simple in structure, easy to process, when it had solved motor rotation effectively, the wearing and tearing of alignment bearing cylindrical and stator and metal dust affected the lubricated problem with electric property of motor, had prolonged motor useful life.
Description of drawings
Fig. 1 is structural representation of the present utility model.1-motor shaft wherein, 2-alignment bearing inner ring, 3-alignment bearing outer ring, the back-shaped stop jump ring of 4-, 5-rotor cover, the 6-permanent magnet, the 7-stator, 8-adjusts pad.
Fig. 2 is the structural representation of alignment bearing outer ring.
Embodiment
Further illustrate structure of the present utility model and execution mode below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of motor alignment bearing, comprise alignment bearing inner ring 2, alignment bearing outer ring 3, back-shaped stop jump ring 4, wherein alignment bearing inner ring 2 is by the ceramic material manufacturing, the ceramic coated material of alignment bearing outer ring 3 inner surfaces, alignment bearing inner ring 2 is connected with motor shaft 1 usefulness key, the ceramic material of alignment bearing inner ring 2 and alignment bearing outer ring 3 consists of friction pair, ceramic material has high-wearing feature and non-conductive, magnetic conduction not, and the powder that enters lubricating oil during running reduces and powder can not affect the electric property of motor; The alignment bearing outer ring is provided with runner, can accelerate dynamo oil and flow, and accelerates the alignment bearing heat radiation; Be respectively arranged with groove on the inner circle of the cylindrical of alignment bearing outer ring 3 and stator 7, back-shaped stop jump ring 4 one ends are stuck in the groove of stator 7, the other end is stuck in the groove of alignment bearing outer ring 3, the pretightning force that produces by back-shaped stop jump ring 4 self strain is fitted alignment bearing outer ring 3 and stator 7, stops to produce relative motion between the two.
