Abstract
The utility model relates to the technical field of motors, especially to a motor rotor. The motor rotor comprises an output shaft, a shaft sleeve, ball bearings and a magnet ring, wherein the output shaft is in threaded connection with the shaft sleeve; the ball bearings are arranged on both sides of the sleeve; the magnet ring is disposed outside the shaft sleeve; one side of the ball bearing which is on the left side of the sleeve is provided with an angular contact thrust bearing; and the magnet ring and the shaft sleeve are fixedly connected through an adhesive. The motor rotor is simple, compact and reasonable in structure, fast and convenient for assembly and reliable in connection; the rotation resistance of the rotation shaft is reduced, and the service life of the rotor is prolonged; and at the same time, prevents current leakage during a work process of the motor, and thus reliability of operation of the motor is substantially improved while the motor safety voltage grade is improved, and the motor rotor is easy for use and promotion.
Description
Technical field
The utility model relates to a kind of technical field of motor, especially a kind of rotor.
Background technology
Motor is the conversion equipment of realizing electric energy and mechanical energy and mechanical energy and electric energy, and rotor is the rotating parts in motor, belongs to easy wearing detail.When existing motor rotor shaft rotates, comparison of resistance is large, and serious wear has shortened useful life of rotor, and motor easy Leakage Current in use, and security performance is low.
The utility model content
Existing rotor rotary resistance is large in order to overcome, serious wear and useful life short deficiency, the utility model provides a kind of rotor.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotor, comprise output shaft, axle sleeve, ball bearing and magnet ring, and output shaft is connected with sleeve thread, and axle sleeve both sides are provided with ball bearing, and the axle sleeve outside is provided with magnet ring.
According to another embodiment of the present utility model, comprise that further ball bearing one side on the left of axle sleeve is provided with angular contact thrust bearing.
According to another embodiment of the present utility model, comprise that further magnet ring is fixedly connected with by adhesive with axle sleeve.
The beneficial effects of the utility model are, this motor rotor construction is simple, compact and reasonable, easy to assembly quick, connect reliably, reduced the resistance that rotating shaft is rotated, extended the useful life of rotor, avoided simultaneously the motor leakage of electric current in the course of the work, when improving the motor safety electric pressure, greatly improved the reliability of machine operation, be easy to use and promote.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. output shafts in figure, 2. axle sleeve, 3. ball bearing, 4. magnet ring, 5. angular contact thrust bearing.
Embodiment
Structural representation of the present utility model as Fig. 1, a kind of rotor, comprise output shaft 1, axle sleeve 2, ball bearing 3, magnet ring 4 and angular contact thrust bearing 5, output shaft 1 is threaded with axle sleeve 2, axle sleeve 2 both sides are provided with ball bearing 3, axle sleeve 2 outsides are provided with magnet ring 4, and ball bearing 3 one sides in axle sleeve 2 left sides are provided with angular contact thrust bearing 5, and magnet ring 4 is fixedly connected with by adhesive with axle sleeve 2.
During use, output shaft 1 is threaded with axle sleeve 2, reduce the probability of Leakage Current, axle sleeve 2 outsides are provided with magnet ring 4, and magnet ring 4 is fixedly connected with by adhesive with axle sleeve 2, and axle sleeve 2 both sides are provided with ball bearing 3, the wearing and tearing of rotor have been reduced, ball bearing 3 one sides in axle sleeve 2 left sides are provided with angular contact thrust bearing 5, have improved bearing capacity and the axial rigidity of rotor, reduce its friction torque.This motor rotor construction is simple, compact and reasonable, easy to assembly quick, connect reliable, reduced the resistance that rotating shaft is rotated, extended the useful life of rotor, avoided simultaneously the motor leakage of electric current in the course of the work, when improving the motor safety electric pressure, greatly improved the reliability of machine operation, be easy to use and promote.
