Abstract
The utility model provides a motor main shaft output end structure for direct connection driving, being suitable for equipment with an axial reciprocating motion core shaft while the rotor rotates around the axis and equipment without core shafts. On the basis of common motor main shaft, the inside of the output end is opened with a long inner hole. The front part of the long inner hole is embedded with a sliding inner jacket which leads the core shaft of the rotor to move in the long inner hole; in order to ensure the reliable positioning of the rotor wheel on the output end of the motor main shaft, and external screw threads are designed on the shaft end. a check washer and a round nut can be arranged on the external screw threads to lock the hub of the rotor; a screw hole for pulling screw installation is opened on the shaft end face in consideration of the convenient assembly and disassembly of the rotor. The structure overcomes the defects of the existing motor main shaft structure, the middle shaft is removed, the axial length of the equipment is effectively shortened and the reliability and economical efficiency of the equipment are improved.
Description
Technical field:
The utility model relates to the electromechanics technical field, refers in particular to a kind of structure that is used for the electric machine main shaft output terminal of direct connection transmission.Be used for rotor is directly installed on electric machine main shaft (this kind of drive claims " direct connection transmission "), particularly be applicable to the equipment that self has the axially reciprocating mandrel when rotor rotates around axis, for example movable vane adjustable fan (a kind of in impeller rotation each blade on it can change the ventilation equipment of setting angle); Also be suitable for the not equipment use of belt carcass axle of common rotor.
Background technique:
The output terminal of common electric machine main shaft generally has only dress hub face, keyway and axial end three parts, and some has outside thread or internal thread and is used to the rotor that locks and adorned.And some special rotating machineries such as movable vane adjustable fan at present, owing to have the mandrel that needs axially reciprocating in its rotor, be difficult to rotor directly is installed on the output terminal of electric machine main shaft according to the prior motor main shaft structure, common way is to adopt a jack shaft, the one head links to each other with rotor, and the other end links to each other with motor, and the result causes the axial length of this equipment longer, the boundary dimension of equipment is huge, is not suitable for installing and using in than small space at subway tunnel etc.; The reliability of equipment and Economy also decrease in addition.
Patent content:
The purpose of this patent is to overcome the existing structural deficiency of electric machine main shaft, and the structure of the electric machine main shaft output terminal that is used for the direct connection transmission of a kind of axial length weak point, economic and reliable is provided,
For achieving the above object, the technological scheme that provides of this patent is: include dress hub face, long endoporus, sliding sleeve, axial end, outside thread, locking groove, keyway and screw.Dress hub face at the output terminal of electric machine main shaft can be the cylndrical surface or the conical surface, has keyway on it; Between dress hub face and the axial end is outside thread, has locking groove on the outside thread; Axial end upper edge axis has screw and long endoporus toward the direction of dress hub face, and wherein long endoporus arranges that between two parties screw is positioned at the both sides of long endoporus; Long endoporus is the ladder cylindrical hole, and its position diameter near axial end is bigger, is used to install sliding sleeve; Dress hub face and sliding sleeve have the requirement of coaxality.
After the utility model adopts technique scheme, cancel the jack shaft of prior art, rotor can directly be installed on the output terminal of electric machine main shaft, effectively shortened the axial length of equipment, improved the reliability and the Economy of equipment simultaneously.
Description of drawings:
Fig. 1 is the front view of this structure.
Fig. 2 is the plan view of this structure.
Fig. 3 is the left side view of this structure.
Embodiment:
The utility model is generally finished when electric machine main shaft is made, and the other parts with motor are assembled into complete motor then.See also Fig. 1, Fig. 2, shown in Figure 3.On the basis of the structure of common electric machine main shaft, leave long endoporus in the inside of its output terminal, on axle head, designed outside thread, consider the convenience of rotor mounting or dismounting, on axial end, also have for installing.Dress hub face 1 at the output terminal of electric machine main shaft can be the cylndrical surface or the conical surface, has keyway 7 on it; Between dress hub face 1 and the axial end 4 is outside thread 5, has guaranteed the reliable location of wheel hub on the electric machine main shaft output terminal of rotor.Have locking groove 6 on the outside thread 5, lock washer and round nut can be installed thereon, the wheel hub of rotor is locked; Axial end 4 upper edge axis have screw 8 (being generally 2) and the long endoporus of using for the drawing screw rod 2 toward the direction of dress hub face 1, and screw 8 makes the convenience of rotor mounting or dismounting, and the front portion of long endoporus studs with sliding inner sleeve, and the mandrel of rotor can be moved at this long endoporus; Wherein long endoporus 2 arranges that between two parties screw 8 is positioned at the both sides of long endoporus 2; Long endoporus 2 is the ladder cylindrical hole, and its position diameter near axial end 4 is bigger, is used to install sliding sleeve 3; Dress hub face 1 and sliding sleeve 3 have the requirement of coaxality.
The function that the rotor that this structure can allow this kind equipment of movable vane adjustable fan for example have mandrel directly is installed on the electric machine main shaft realizes as follows:
1. driving key is put into keyway 7;
2. the wheel bore of rotor is inserted on the dress hub face 1, note on the wheel bore of rotor the keyway position should with driving key as far as possible over against, otherwise be difficult to be inserted in.This moment can be by installing screw rod on screw 8, by setting tool such as pressing plate, jack the wheel hub of rotor is pressed onto the shaft shoulder position of dress hub face 1, sheds the setting tool on screw 8 then;
3. put into lock washer at locking groove 6 places, and be screwed on the outside thread 5 round nut with the wheel hub locking of rotor on dress hub face 1, at last the stop tongue on the lock washer is broken off with the fingers and thumb in the draw-in groove of round nut;
4. the alignment axis with rotor passes sliding sleeve 3, and inserts in the long endoporus 2, checks that its reciprocating elasticity along axial direction of affirmation is suitable promptly to finish installation.
When this structure is used to install the rotor of belt carcass axle not, only need to carry out above-mentioned steps 1～step 3, promptly its long endoporus 2 and sliding sleeve 3 are not utilized, but do not influence the use of motor.
