Description
Technical field
The utility model relates to motor and manufactures field and other manufacture fields needing moment of torsion to export, and is the mechanism that a kind of motor shaft moment of torsion exports specifically.
Background technique
Moment of torsion exports general by the external splines on output shaft, flat key, and the external splines on the torque axis coordinated with its internal spline is externally connected and is achieved.It is large that load is stood in joint, easily damages, and external splines and flat key, once damage, are difficult to repair, and need to change.Because the material price of output shaft and torque axis is general higher, so the economic loss caused is also larger.There is the inefficacy of spline, flat key also can delay the manufacture cycle of product again.Need to design a kind of new torque output shaft structure for this reason
Model utility content
The purpose of this utility model is to provide a kind of new torque output shaft structure, and concrete technological scheme is as follows:
A kind of Motor torque output shaft structure, is characterized in that: comprise short torque axis, rotor shaft, torque axis assembling;
Described torque axis assembling comprises semiaxis, axle sleeve, and described axle sleeve is sleeved on also key cooperation on semiaxis;
Described short torque axis coordinates with shaft sleeve key;
Described rotor shaft coordinates with described half axle key;
Described semiaxis and rotor the tip of the axis arrange shaft seal structure; Described shaft seal structure comprises that axle is stifled, adhesive tape, lock washer with tongue at outside, bolt, back-up ring; Described axle blocks up, lock washer with tongue at outside, back-up ring are bolted top at semiaxis successively; Adhesive tape is arranged between the stifled and rotor shaft of axle; In the groove that back-up ring embedding rotor shaft is arranged.
Advantage of the present utility model: be 1. conducive to protection rotor axis of electric internal spline injury-free; 2. torque axis assembling axially locating is safe and reliable; 3. can reduce rotor shaft, torque axis assembling needed for precious materials, cost-saving.
Accompanying drawing explanation
Fig. 1 is the utility model basic block diagram;
Fig. 2 is torque axis package assembly schematic diagram;
Fig. 3 is shaft seal structure schematic diagram;
In figure, 1 short torque axis, 2 rotor shafts, 3 torque axis assemblings, 4 rotor iron cores, 5 axle sleeves, 6 semiaxis, 7 axles are stifled, 8 adhesive tape, 9 lock washer with tongue at outsides, 10 bolts, 11 back-up rings.
Embodiment
Basic structure of the present utility model is shown in Fig. 1-Fig. 3, and its agent structure has short torque axis, rotor shaft, torque axis to assemble, and short torque axis is easily damaged parts.Fig. 2 illustrates that torque axis assembling is made up of axle sleeve, semiaxis two-part, and its Intermediate shaft sleeve is the critical component that moment of torsion exports, and semiaxis is easily damaged parts.This new structure only has the material of critical component axle sleeve to ensure, the short torque axis of easily damaged parts, semiaxis can select suitable material depending on different situations.
In Fig. 3, the internal spline of rotor shaft is coordinated by spline pair with semiaxis, bolt
Block up the rear portion being arranged on torque axis assembling through axle, lock washer with tongue at outside plays locking effect.Back-up ring is fixed on rotor shaft rear portion by stifled for axle, and adhesive tape is obturator.
The effect of lock washer with tongue at outside prevents bolt from rotating, and adhesive tape effect prevents extraneous water and oil from entering.Torque axis assembling front end, rear end is internal spline, by connecting torque axis and extraneous transmitting torque.
