Abstract

The invention discloses a high-performance air bearing motor which comprises a motor body, wherein air bearings are arranged at two ends of the motor body, air accumulation chambers are arranged between the inner walls of the air bearings and connected through air inlets, a plurality of air holes are formed in the air accumulation chambers, two ends of each air inlet are led out of the air bearings and communicated with the outside air, a motor rotor is led in between the air bearings, and a motor stator is arranged outside the motor rotor. By the mode, the air source can be reserved during starting, quick starting is achieved, starting is free of friction, the air source is not needed at high speed, the full-suspension state is changed from static state to high speed, the starting can be frequently carried out, and the service life and the efficiency of the whole machine are greatly improved.

Description

High-performance air bearing motor

Technical Field

The invention relates to the field of generators, in particular to a high-performance air bearing motor.

Background

Air bearings refer to sliding bearings that use a gas (usually air, but other gases are possible) as a lubricant. Air is less viscous than oil, is resistant to high temperatures, is pollution-free, and is therefore used in high-speed machines, instruments, and radioactive devices, but has a lower load capacity than oil. Air bearings fall into three broad categories: aerostatic, aerodynamic, and squeeze film bearings. Aerostatic bearings are widely used in the general industry.

Disclosure of Invention

The invention mainly solves the technical problem of providing a high-performance air bearing motor, which can reserve an air source during starting, realize quick starting, has no friction during starting, does not need the air source at high speed, is in a full suspension state from static state to high speed, can be started frequently, and greatly improves the service life and the efficiency of the whole machine.

In order to solve the technical problems, the invention adopts a technical scheme that: the utility model provides a high performance air bearing motor, includes the motor body, the motor body both ends are equipped with air bearing, be equipped with long-pending air chamber between the air bearing inner wall, connect through the inlet port between the long-pending air chamber, be equipped with a plurality of bleeder vents on the long-pending air chamber, the inlet port both ends are derived air bearing outside and outside air intercommunication, leading-in electric motor rotor between the air bearing, the electric motor rotor outside is equipped with motor stator.

In a preferred embodiment of the present invention, the air inlet is formed at a position offset from the motor rotor, and the air inlet is longitudinally disposed through the air bearing.

The invention has the beneficial effects that: the invention can reserve an air source during starting, realizes quick starting, has no friction during starting, does not need the air source at high speed, is in a full suspension state from static to high speed, can be started frequently, and greatly improves the performance, the service life and the efficiency of the whole machine.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention includes:

the utility model provides a high performance air bearing motor, includes motor body 1, 1 both ends of motor body are equipped with air bearing 2, be equipped with long-pending air chamber 3 between the 2 inner walls of air bearing, connect through inlet port 4 between the long-pending air chamber 3, be equipped with a plurality of bleeder vents on the long-pending air chamber 3, the export of inlet port 4 both ends air bearing 2 outer and outside air intercommunication, leading-in electric motor rotor 5 between the air bearing 2, electric motor rotor 5 outside is equipped with motor stator 6.

In addition, the air inlet 4 is arranged in a staggered manner with the motor rotor 5, and the air inlet 4 longitudinally penetrates through the air bearing 2.

The working principle of the invention is that an air source is reserved through the air accumulation chamber 3 during starting, so that the quick starting is realized, no friction is generated during starting, the air holes on the air accumulation chamber 3 reversely exhaust air during high-speed state transition, no air source is needed during high speed, the full suspension state is changed from static state to high speed, and the air accumulation chamber can be frequently started, so that the service life of the performance and the efficiency of the whole machine are greatly improved.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
