Abstract
The utility model discloses a motor rotating rectifier separating type fixing device, which is characterized in that a main body supporting piece of the device is made of a metal plate, the end surface of the metal plate is provided with a threaded hole for fixing a motor rotating rectifier, and the end surface of the metal plate is provided with lightening holes; the lightening holes correspond to the rivet holes of the motor, and rivet space is reserved. The inner ring is provided with a shaft hole and a key groove, and the device is independently fixed on the rotating shaft through the close fit of the flat key and the shaft and can be separated from the iron core. The motor rotating rectifier is fixed on the separated fixing device through bolts. The technical effects of the utility model are that: (1) the novel and reliable mounting and fixing device for the motor rotating rectifier is provided; (2) the motor rotating rectifier is convenient to install and maintain; (3) simple processing and low cost.
Description
Technical field
The utility model is related to motors, and in particular to a kind of fixing device of generator rotating rectifier.
Background technology
Military Power pursues high maintainability at present, and component requires easily to replace easy-maintaining.Rotating rectifier conduct in motor
One important repair component, its maintainability directly affect the Maintainability index of whole system.
The fixed form of traditional rotating rectifier is directly anchored on iron core with screw bolt and nut, the fixed form it is excellent
Point is that processing and fabricating is simple, and shortcoming is that maintainability is poor, is needed rotor and stator separation.Also plant mode：Increase by one
Iron core is first fixed on stent by iron core bracket, then rotating rectifier is fixed by bolts on stent, the fixed form it is excellent
Point is maintainability height, does not need to rotor separation and can be carried out repairing, and shortcoming is the increase in parts, increases multiple tracks production
Process reduces production efficiency.
To overcome disadvantages mentioned above, a kind of new reliable motor rotating rectifier installation fixed form is developed, improves repair
Production efficiency is not influenced while property.
Invention content
The purpose of this utility model is to provide a kind of new reliable motor rotating rectifier fixing device for installing, improve
Production efficiency is not influenced while rotating rectifier maintainability.
The utility model is realized in this way：
A kind of motor rotating rectifier separate type fixing device, the device are metalwork, and rounded, end face center offers
Axis hole and keyway, end face offer several threaded holes and several lightening holes.
In use, the device is individually fixed on alternator shaft by the tight fit by flat key and alternator shaft,
It is separated with the iron core of generator.Coordinated by the threaded hole of bolt and the device, rotating rectifier is fixed on the apparatus.
The ventilation hole correspondence of the rivet hole of lightening hole and generator iron-core, generator iron-core, is conducive to lead to while conceding rivet space
Wind.
Preferably, the quantity of the threaded hole is 4.
Preferably, the quantity of the lightening hole is 6.
The operation principle of the utility model is：Generator rotating rectifier separate type fixing device is equivalent to fixed tightening
Nut, loosens or nut will not be moved or be rotated when fastening bolt, thus does not interfere with the rotation of bolt, facilitates rotation
Rectifier is installed on dismounting.Meanwhile the fixing device is detached with iron core, is processed convenient for making.
The utility model has the technical effect that：(1) it is solid to provide a kind of new reliable generator rotating rectifier installation
Determine device；(2) make generator rotating rectifier convenient to install and maintain；(3) processing is simple, at low cost.In short, increase rotary rectifier
The mounting means of device improves the maintainability of rotating rectifier.

Specific embodiment
The utility model is described in further detail below in conjunction with drawings and examples, but the present embodiment is not used to limit
The utility model processed.
The utility model is such to what is implemented, as illustrated in fig. 1 and 2, the motor rotating rectifier separation of the utility model
Formula fixing device 1 is metal processing piece, rounded, opens that there are four the threaded holes of fixed rotating rectifier 3 on metallic plate end face
102, while open there are six lightening hole 104；Inner ring is provided with axis hole 101 and keyway 103.
As shown in Figures 3 and 4, in assembling, lightening hole 104 and iron core rivet hole 201, core ventilation hole 202 correspond to, and concede
Be conducive to divulge information while iron core rivet space；The device is individually fixed on by the tight fit of flat key and alternator shaft
It is separable with iron core 2 in shaft.Rotating rectifier 3 is fixed on generator rotary rectifier by fastening bolt 4 and threaded hole 102
In device separate type fixing device.
