Abstract
The utility model relates to a watertight unilateral concentric dual-output-shaft disrotatory permanent-magnet alternating current servo motor, which is composed of a first motor and a second motor in series connection, and the first motor and the second motor are permanent-magnet alternating current servo motors with the same performance but different shaft extension. The first motor adopts a structure of hollow shaft output, and a flange is reserved at the rear end. The second motor outputs a long shaft which is in butt joint with the first motor at the front end through the flange, and a rotating shaft of the second motor penetrates through a hollow shaft of the first motor. The watertight unilateral concentric dual-output-shaft disrotatory permanent-magnet alternating current servo motor is composed of two permanent-magnet alternating current servo motors, adopts a form of hollow shaft sleeving, achieves the unilateral concentric dual-output-shaft disrotatory function, and can bear 2.4MPa external water pressure. The structure has the advantages of being high in efficiency, small in noise, simple and high in reliability.
Description
Technical field
The utility model belongs to the motor technology field, relates to a kind of permanent magnetic Ac servo motor, and the one-sided concentric pair of shaft of especially a kind of watertight is to revolving permanent magnetic Ac servo motor.
Background technology
In recent years; The structure of coaxial pair of oar occurred having used on the underwater installation in the military affairs both at home and abroad, realized equalising torque in the screw direction of rotation, so can save other bascules to revolving; Saved volume; This structure has lower pressure oscillation and noise reflection, and switching mechanism reduces, and has high reliability.In order to realize coaxial pair of paddle structure of underwater propeller, tradition adopts a servomotor+deceleration switching mechanism, realize with one heart two shafts to revolving function, but this structure transmission efficiency is low, noise big, complex structure.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, provides the one-sided concentric pair of shaft of a kind of watertight to revolving permanent magnetic Ac servo motor, and it can realize that one-sided concentric pair of shaft is to revolving function.
The purpose of the utility model solves through following technical scheme:
The one-sided concentric pair of shaft of this watertight is composed in series by first motor and second motor revolving permanent magnetic Ac servo motor, and said first motor and second motor are two different shaft extensions but the identical permanent magnetic Ac servo motor of performance; Said first motor adopts the structure of hollow shaft output, and flange is reserved in its rear end; Said second motor output is docked with first motor of front end through flange than major axis, and the hollow shaft of first motor is passed in the rotating shaft of second motor.
The rearward end of above-mentioned first motor is provided with first resolver, and the leading section of said second motor is provided with second resolver.
The lead-out wire of above-mentioned first motor, first resolver, second motor and second resolver adopts four pass outlet methods, is drawn by the position between first motor and second motor through the outlet seat.
The one-sided concentric pair of shaft of the watertight of the utility model is made up of the permanent magnetic Ac servo motor of two series connection revolving permanent magnetic Ac servo motor; And adopt the form of hollow shaft suit; Realize one-sided concentric pair of shaft to revolving function, and can bear the 2.4MPa external water pressure.This structure has efficient height, little, simple in structure, the high reliability features of noise.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1 is first motor; 2 is second motor; 3 is first resolver; 4 is second resolver.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, the one-sided concentric pair of shaft of this kind watertight is composed in series by first motor 1 and second motor 2 revolving permanent magnetic Ac servo motor, and first motor 1 and second motor 2 are two different shaft extensions but the identical permanent magnetic Ac servo motor of performance; First motor 1 adopts the structure of hollow shaft output, and flange is reserved in its rear end; 2 outputs of second motor are docked with first motor 1 of front end through flange than major axis, and the hollow shaft of first motor 1 is passed in the rotating shaft of second motor 2.The rearward end of first motor 1 is provided with first resolver 3, and the leading section of said second motor 2 is provided with second resolver 4.
Easy for the assembling that guarantees this unit, resolver " zeroing " is easy, and outlet structure is easy; First resolver 3 is placed the rear end of first motor 1; Second resolver 4 places the front end of second motor 2, and the lead-out wire direction of first motor 1 and second motor 2 is consistent with revolving the change installation direction, so far; This unit is all goes out the centre (position between first motor 1 and second motor 2) that line position all concentrates on unit, thereby can concentrate outlet.Before the general assembly, first unit of being made up of first motor 1 and first resolver 3 can independently be debugged with the unit of being made up of second motor 2 and second resolver 42, has avoided after the general assembly completion separate unit unit to break down and has caused whole unit fault.
In the most preferred embodiment of the utility model, it is 4 groups that the lead-out wire of whole unit is divided into, and is respectively first motor, 1 lead-out wire; Second motor, 2 lead-out wires, first resolver, 3 lead-out wires, second resolver, 4 lead-out wires; For fear of electromagnetic wave signal is produced interference; Adopt the mode of 4 tunnel outlets, lead-out wire adopts special shielding watertight cable, seals through the outlet seat.
