Motor with Thrust Bearing

Abstract

A motor includes: a base having a bearing sleeve, with the bearing sleeve having an opening end and a sealing end, with the opening and sealing ends opposite to each other; a stator coupled with the base; a rotating member rotatably received in and coupled with the bearing sleeve, with the rotating member comprising a shaft and a limiting portion, wherein a first end of the shaft connects with the limiting portion, a second end of the shaft has a coupling portion; a thrust bearing arranged between the shaft and an inner surface of the bearing sleeve, so that the limiting portion is between the thrust bearing and the sealing end; a pressing member coupled with the bearing sleeve and received therein for positioning the thrust bearing; and a hub coupled with the coupling portion of the shaft and having a permanent magnet corresponding to the stator.

Description

technical field [0001] The present invention relates to a motor with a thrust bearing, in particular to a motor capable of pressing against and positioning the thrust bearing. Background technique [0002] Please refer to figure 1 As shown, the conventional motor 9 with a thrust bearing includes a bracket 91 , a stator 92 and a rotor 93 . The bracket 91 is combined with a bearing housing 911. A thrust bearing 912 and a thrust plate 913 are arranged inside the bearing housing 911. The opposite ends of the bearing housing 911 each have an opening, one of which is open for the rotor 93. Combining, the other end opening is combined with a cover 914; the stator 92 is combined with the outer peripheral wall of the bracket 91; the rotor 93 has a hub 931, and the hub 931 integrally forms a ring flange 932 and is provided with a rotating shaft 933, the ring The flange 932 is located between the bracket 91 and the bearing housing 911 to provide functions such as dust-proof or oil-pr...

AI Technical Summary

Problems solved by technology

[0003] When the thrust bearing 912 of the above-mentioned existing motor 9 with a thrust bearing is fixed inside the bearing housing 911, the thrust bearing 912 can be used to limit the thrust plate 913 to prevent the rotor 93 fixed with the thrust plate 913 from However, since the motor 9 with the thrust bearing is not further provided with a member for fixing the thrust bearing 912 inside the bearing housing 911, if the thrust bearing 912 is not If it is indeed fixed inside the bearing housing 911, and there are problems such as loosening or falling off, the thrust bearing 912 will not be able to effectively limit the thrust plate 913, causing the rotor 93 to also have problems such as loosening or falling off

Furthermore, since the opening of the bearing housing 911 of the motor 9 with thrust bearings does not have an oil-leakage design, oil leakage problems may also occur, which cannot ensure the service life of the motor 9, so there is a need for improvement.
