Abstract
The utility model relates to an encoder support installation structure for a slip ring motor, wherein the structure comprises a motor rotating shaft, an encode, an encoder small shaft and a rotor cable. A steel jacket is sleeved on the end portion of the motor rotating shaft and then a slip ring is sleeved outside the steel jacket. The rotor cable is arranged inside an axial routing hole. One end of a transition support is fixedly installed on the end surface of the steel jacket and the other end of the transition support is fixedly connected with the encoder small shaft. The encoder is installed on the encoder small shaft. The transition support is formed by a front circular plate, a rear circular plate and a plurality of connecting posts; the front circular plate and the rear circular plate form an open frame by the connecting posts; and the front circular plate is a hollow plate body. The rotor cable arranged inside the axial routing hole of the motor rotating shaft passes through the front circular plate of the transition support, comes out of the space between the connecting columns and is fixedly connected with the slip ring. The installation structure is simple, firm and reliable by depending on the front edge fit and bolt fastening; and the encoder and the transition support can be installed and disassembled conveniently and the maintainability is high.
Description
Technical field
The utility model relates to the manufacturing of the slip ring motor of field of motor manufacturing, relates in particular to a kind of slip ring motor and uses the encoder rack mounting structure.
Background technology
Slip ring motor a lot of occasions when operation need test the speed, and the encoder that is used to test the speed is installed on the tail end of machine shaft usually, and slip ring also is installed in roller end.For example in recent years along with the developing rapidly of green energy resource, be exactly a kind of typical slip ring motor as the MW level Wound-rotor type double-fed wind power generator of mainstream model.The Wound-rotor type double-fed wind power generator needs the rate signal of reliable and stable to obtain through encoder.The rotating shaft end of double-fed wind power generator is equipped with slip ring simultaneously, but encoder can not be directly installed in the double-fed wind power generator rotating shaft.Usually there are three reasons to cause encoder can't be directly installed on the machine shaft; The one, the rotor cable of slip ring motor is connected with slip ring through the rotating shaft axis hole, has taken the installing space of the little axle of encoder; The 2nd, machine shaft axially is processed with deep hole in the slip ring section, but the installation dimension of rotating shaft end face is limited; The 3rd, encoder is installed little axle and compared with alternator shaft, and is small-sized, can not directly install and fix, and needs transition dexterously.
Summary of the invention
The utility model is to the deficiency of prior art, provides a kind of simple in structure, easy installation and removal, the reliable slip ring motor of connection to use the encoder rack mounting structure.
The utility model provides following technical scheme for solving the problems of the technologies described above: a kind of slip ring motor is used the encoder rack mounting structure, comprises machine shaft, encoder; The little axle of encoder, rotor cable; Machine shaft end elder generation suit steel bushing, slip ring is sleeved on outside the steel bushing again, and described rotor cable is arranged in the axial cable hole of machine shaft; An end that it is characterized in that transition bracket is fixedly mounted on the steel bushing end face; The other end of transition bracket is fixedly connected the little axle of encoder, and encoder is installed on the little axle of encoder, and described transition bracket is made up of former and later two disks and some joint pins; Preceding disk and rear disk constitute open frame through joint pin; Preceding disk is the hollow disk body, and the rotor cable in the axial cable hole of said machine shaft passes the preceding disk of transition bracket, is fixedly connected from passing between joint pin with slip ring.
Further preferred as the utility model, the preceding disk of transition bracket is through being bolted on the steel bushing end face.
As the further improvement of the utility model, be respectively arranged with the seam that connects on steel bushing end face and the preceding disk end face, make encoder support and slip ring motor install more firm through this kind setting.
As the further improvement of the utility model, the joint pin of transition bracket, preceding disk and rear disk are the integrative-structures of welding, are provided with easy to makely through this kind, and it is stable to be connected firmly.
Further improvement as the utility model; The little axle bolt of encoder is fixed on the rear disk of transition bracket; Through this kind setting the installation site of the little axle of encoder is increased, vacated the line position of walking of rotor cable simultaneously, make the rotor cable simple and convenient with being connected of slip ring.
As the further improvement of the utility model, the end that the little axle of encoder is connected with rear disk is plate-like or support shape, and the other end that encoder is installed is circular shaft shape or multidiameter shape, selects the little shape shaft of encoder arbitrarily according to processing technology.
As the further improvement of the utility model, the little axle of encoder is overall structure or divides attachment structure.
The advantage of the utility model is: 1, rely on seam to cooperate and bolted, the encoder mounting bracket is simple in structure, and is solid and reliable; 2, encoder and transition bracket easy installation and removal, it is maintainable high; 3, the little shaft size of the installation of encoder does not receive the restriction of slip ring motor rotating shaft size basically; 4, the rotor cable can pass through axis hole and encoder transition bracket easily, is connected with slip ring again.
