Abstract
The utility model relates to a rotary transformer structure of an easily-installed servo motor, which has the technical points that the rotary transformer is fixed on a rear end cover via three uniformly-distributed screws by passing by a pressing plate, the rotor of the rotary transformer is fixed on the non-shaft extension end of a motor main shaft via one screw by passing by an adapter sleeve, a cover is fixed on the rear end cover via three uniformly-distributed screws, because both the connection of the stator of the rotary transformer and the rear end cover as well as the connection of the rotor of the rotary transformer and the non-shaft extension end of the main shaft adopt the seam allowance locating connection, through seam allowance standard locating, the coaxiality requirement of the rotary transformer and the motor is ensured, meanwhile, the installation is convenient, the processing is convenient, the cost is low, and the service life of the rotary transformer of the servo motor is prolonged.
Description
Technical field
The utility model relates to a kind of accessory of servomotor, particularly a kind of servomotor rotating transformer structures of easy installation.
Background technology
Development along with converter technique, the application of servomotor in industry is more and more wider, servomotor requires than higher for the control of motor speed, need measure accurately and feed back rotating speed of motor, generally will resolver be installed on the main shaft of motor and come rotating speed of motor is measured and controlled.In the prior art, only by stainless steel strut resolver is installed on the motor, is difficult to guarantee the axiality of electric machine main shaft and resolver, thereby influence is to the certainty of measurement and the safe operating life of motor speed with screw.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and servomotor rotating transformer structures that a kind of easy installation is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of servomotor rotating transformer structures of easy installation, it is made up of resolver (rotor), pressing plate, adapter sleeve, swivel nut, lid, it is characterized in that the resolver stator is fixed on the rear end cap by pressing plate by three uniform screws, the resolver rotor is fixed on the non-shaft stretching end of electric machine main shaft by a screw by adapter sleeve, below all adopt seam to be located by connecting, cover by three uniform screw on rear end cap.Swivel nut is screwed in around the lid on hole, and lead-in wire extracts by swivel nut, has played the degree of protection effect that improves motor, resolver like this.
Compared with prior art, advantage of the present utility model is a kind of easy installation servomotor rotating transformer structures, because being connected between resolver stator and the rear end cap, resolver rotor all adopt seam to be located by connecting with being connected of main shaft non-shaft stretching end, therefore pass through the location of its seam benchmark, guaranteed the requirement of the axiality of resolver and motor, and be convenient to install, easy to process, with low cost, also prolonged simultaneously servomotor resolver useful life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
In the accompanying drawing 1: part name: 1, stator; 2, rear end cap; 3, screw; 4, swivel nut; 5, pressing plate; 6, screw; 7, adapter sleeve; 8, screw; 9, resolver (rotor); 10, lid; 11, main shaft.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of servomotor rotating transformer structures of easy installation, it is made up of resolver (rotor) 9, pressing plate 5, adapter sleeve 7, swivel nut 4, lid 10, its installation process is that resolver 9 stators are fixed on the rear end cap 2 by pressing plate 5 by three uniform screws 6, resolver 9 rotors are fixed on by adapter sleeve 7 on the non-shaft stretching end of electric machine main shaft 11 by a screw 8, and lid 10 is fixed on the rear end cap 2 by three uniform screws 3.Swivel nut 4 is screwed on the hole of covering around 10, and lead-in wire extracts by swivel nut 4, has played the degree of protection effect that improves motor, resolver like this.
The servomotor rotating transformer structures of described a kind of easy installation, because being connected between resolver 9 stators and the rear end cap 2, resolver 9 rotors and being connected of non-shaft stretching end of electric machine main shaft 11 all adopt seam to be located by connecting, therefore pass through the location of its seam benchmark, guaranteed the axiality requirement of resolver 9 with motor, motor is when rotating, the direct driven rotary transformer 9 rotors rotation of the rotation of electric machine main shaft 11 is measured and is controlled by 9 pairs of rotating speed of motor of resolver.
