Abstract
Disclosed is a test run structure for a brushless excitation synchronization motor, comprising an exciter arranged upon a motor shaft and a test run slip ring, wherein the exciter is installed at the rear portion of the motor shaft; the rear end face of the motor shaft is coaxially connected with a segment of a dummy shaft; and the test run slip ring is installed upon the dummy shaft. The test run structure of the utility model is capable of avoiding the risks caused by multiple sleeving of the exciter during the whole test run process of the motor, reducing the motor installation frequency, and saving working hours.
Description
Technical field
The utility model relates to a kind of test run structure of brushless synchronous machine.
Background technology
After motor is installed end, for the properties of guaranteeing motor is in good state, need carry out test run to motor, namely motor is carried out the body test.The motor body test is before the motor rotation motor internal parts to be carried out the check of technical performance.Brushless synchronous machine is being done body when test, is about to brushless excitation and changes the conventional brush synchronous machine that has into, need this moment at machine shaft 10 test run slip rings 2 to be installed, and the installation site of test run slip ring 2 is generally the installation site (see figure 1) of exciter.Do first dynamic balance test of rotor, this moment, exciter was done dynamic balancing with rotor after must installing, and when the motor test run, exciter is removed, in the position of exciter the test run slip ring is installed, do the body test, after the body off-test, remove the test run slip ring, exciter is installed again.Process is: exciter hot jacket rotor → rotor dynamic balancing → exciter is extracted → is installed test run slip ring → motor general assembly → motor body test → motor disintegration rotor and extracts → tear open test run slip ring → exciter hot jacket → motor general assembly → motor excitation test out.So not only cause exciter is installed repeatedly, easily cause the damage of exciter simultaneously.
The brushless synchronous machine of rolling bearing structure not only will be dismantled exciter, and will dismantle rolling bearing 3 when test run slip ring 2 is installed, and very easily causes bearing to scrap, as shown in Figure 2.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of test run structure of brushless synchronous machine is provided, it can be evaded in the whole commissioning process of motor and repeatedly is set with the risk that exciter causes, and has reduced simultaneously the installation number of times of motor, saves man-hour.
The technical scheme that realizes above-mentioned purpose is: a kind of test run structure of brushless synchronous machine, comprise the exciter and the test run slip ring that are installed on the described machine shaft, wherein,
Described exciter is installed in the rear portion of described machine shaft;
Connect coaxially one section dummy shaft on the end face of the non-shaft stretching end of described machine shaft;
Described test run slip ring is installed on the described dummy shaft.
The test run structure of above-mentioned brushless synchronous machine, wherein, the structure of the forward and backward bearing of described brushless synchronous machine is sliding bearing or rolling bearing;
When the structure of the forward and backward bearing of described brushless synchronous machine was sliding bearing, described exciter was installed on the described machine shaft at rear portion of described rear bearing;
When the structure of the forward and backward bearing of described brushless synchronous machine was rolling bearing, described exciter was installed on the described machine shaft of front portion of described rear bearing
The technical scheme of the test run structure of brushless synchronous machine of the present utility model, the installation site of test run slip ring is changed into the end face of rotating shaft by the installation site of exciter, so just can not affect the installation of exciter, in the whole commissioning process of motor, just need not again repeated disassembled and assembled exciter, evaded and repeatedly be set with the risk that exciter causes, reduce simultaneously motor number of times is installed, save man-hour.

Embodiment
In order to understand the technical solution of the utility model better, also be elaborated by reference to the accompanying drawings below by specific embodiment:
See also Fig. 3 and Fig. 4, the test run structure of a kind of brushless synchronous machine of the present utility model comprises the exciter 1 and the test run slip ring 2 that are installed on the machine shaft 10, wherein,
The structure of the forward and backward bearing on the brushless synchronous machine is sliding bearing or rolling bearing;
Exciter 1 is installed in the non-shaft stretching end of machine shaft 10;
When the structure of the forward and backward bearing of brushless synchronous machine was sliding bearing, exciter 1 was installed on the machine shaft at rear portion of rear bearing 3 ';
When the structure of the forward and backward bearing of brushless synchronous machine was rolling bearing 3, exciter 1 was installed in (see figure 3) on the machine shaft 10 of front portion of rear bearing;
Connect coaxially one section dummy shaft 20 by the technique screw on the end face of the non-shaft stretching end of machine shaft 10;
Test run slip ring 2 is installed on the dummy shaft 20;
When the structure of the forward and backward bearing of brushless synchronous machine was sliding bearing, dummy shaft 20 can be the stationary part (see figure 3) that test run slip ring 2 is avoided exciter 1.
Adopted the test run structure of brushless synchronous machine of the present utility model, the mounting process order of the test run of brushless synchronous machine just becomes:
Exciter hot jacket rotor → rotor dynamic balancing → installation test run slip ring → motor general assembly → motor body is tested → is shielded test run slip ring line, connects exciter → the motor excitation test.
The test run structure of brushless synchronous machine of the present utility model has been evaded the risk that repeatedly is set with exciter and causes, and reduces simultaneously motor number of times is installed, and saves man-hour.To adopting the brushless synchronous machine of rolling bearing structure, avoided increase to dismantle the number of times of rolling bearing and easily cause the phenomenon of damage of the bearing to occur.Technique screw by the machine shaft end face connects dummy shaft in addition, can also improve tool standard.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
