Abstract
The utility model discloses a connection structure between an air compressor and a driving motor thereof, which comprises the following components: a main shaft of the air compressor, and a motor rotating shaft which drives the main shaft to rotate. A rotor is fixed on the motor rotating shaft. A stator is equipped in a closed space which is composed of a front end cap, a base and a back end cap. The front end cap is fixedly connected with the air compressor. The main shaft is provided with a key slot and is in transmission connection with a taper sleeve through a key. The taper sleeve is in taper matching with the motor rotating shaft and is fixed by a bolt in an axial direction. According to the connection structure provided by the utility model, through the transition connection manner of the taper sleeve, the rotor of the motor can be conveniently detached for separating the rotor of the motor from the main shaft, thereby facilitating body maintenance. Furthermore through changing dimension of the inner hole of the taper sleeve, the motor with same specification is suitable for random motors without changing the rotor structure of the motor.
Description
Technical field
The utility model relates to a kind of air compressor, is specifically related to the draw bail of the permanent magnet synchronous motor of a kind of air compressor and its operation of driving.
Background technology
Air compressor adopts asynchronous motor or permanent magnet synchronous motor to drive mostly at present, and its kind of drive has belt transmission or shaft coupling transmission, and its shortcoming is complex structure, and installation accuracy influences serviceability and the life-span of equipment.The structure that directly drives of a kind of permanent magnet motor of certain utility model bulletin for example, its connection scheme is that the rotor transmission shaft with the air compressor main frame partly prolongs, rotor is installed in the main frame rotating shaft, though this connection scheme has solved the loss of transmission, but shortcoming need to be customized special main frame, and it is long to connect cooperation partly, and influence is installed, and the dismounting meeting during repair and maintenance is very difficult.The bearing of rear end can cause load to increase the lost of life because of the concentricity problem of installing in addition.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, remove and install conveniently the syndeton of the reliable air compressor of serviceability and its drive motors.
The syndeton of a kind of air compressor and its drive motors, comprise the boss rod of air compressor and drive the rotating shaft of boss rod motor rotating, rotor is fixedly arranged on the described machine shaft, and stator is installed in the confined space that is made of front end housing, support and rear end cap; Described front end housing is fixedlyed connected with air compressor, and described boss rod is provided with keyway, connects transmission by key with tapered sleeve, and described tapered sleeve and machine shaft taper fit are axially by bolt.
Described drive motors is permanent magnetism frequency variable synchronous motor.
The utility model is by the transition connecting mode of tapered sleeve, can easily dismantle the rotor of motor, rotor is separated with boss rod, make things convenient for the maintaining of main frame, and can be by the interior hole dimension of change tapered sleeve, make same specification motor be applicable to any main frame, and need not to change motor rotor construction.Utilize permanent magnetism frequency variable synchronous motor driven in addition, can improve compressor assembly efficient, in its prescribed limit, keep exhaust pressure stable by frequency conversion, effectively utilize the characteristic of permanent magnet motor simultaneously, make air compressor system keep higher efficient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for explanation the present invention but not for limiting the scope of the invention.
Referring to Fig. 1, a kind of air compressor that the utility model provides and the syndeton of its drive motors, comprise the boss rod 2 of air compressor 1 and drive boss rod 2 motor rotating rotating shafts 3, on the described machine shaft 3 rotor 4 is arranged fixedly, stator 5 is installed in the confined space that is made of front end housing 6, support 7 and rear end cap 8, and described front end housing 6 is fixedlyed connected with air compressor 1 by bolt I 9; Described boss rod 2 is provided with keyway, connects transmission by key 10 with tapered sleeve 11, and described tapered sleeve 11 and machine shaft 3 taper fit are in order to transmitting torque, and the concentricity of assurance driving section, and is axially fixing by bolt II 12.Drive motors can adopt permanent magnetism frequency variable synchronous motor driven, can improve compressor assembly efficient, in its prescribed limit, keep exhaust pressure stable by frequency conversion, effectively utilize the characteristic of permanent magnet motor simultaneously, make air compressor system keep higher efficient.
