Abstract
The utility model discloses a motor shaft and belongs to the technical field of motors. The motor shaft comprises a rod-shaped shaft main body; a shaft ring extends radially out from the shaft main body; a plurality of radial balance holes are uniformly distributed circumferentially on the outer circumferential surface of the shaft ring; the balance hole is a tapped bind hole; and the number of the balance holes is 24. According to the motor shaft, calibration operation of dynamic balance is concise and convenient, the accuracy is high and the reliability is high.
Description
Technical field
The utility model relates to technical field of motors, particularly a kind of motor shaft.
Background technology
Motor shaft is when High Rotation Speed, if the quality relative rotation axi line skewness of axle claims, this amount of unbalance can cause the transverse vibration of axle, and makes axle be subject to unnecessary dynamic loading, thereby reduce reliability and the useful life of motor, therefore the dynamic balancing calibration for motor shaft is necessary.
The dynamically balanced calibration steps of motor shaft has weighting procedure and duplicate removal method, existing weighting procedure is generally, on the rotor sheet assembly press-fiting on motor shaft, a plurality of balance columns are set, use dynamic balancing machine to measure after the uneven angle and uneven weight of motor shaft quality, reasonably on the balance columns of relevant position, be inserted in the balance gasket of corresponding weight to reach balance quality, then by added balance gasket riveting jail on balance columns.But one end of general rotor sheet assembly only arranges 8 balance columns, and adjustment, also needs to add balance mud and regulate exactly, complex operation, calibration difficulty is high, and easily occurs error during riveted joint, causes balance gasket loosening, thereby causes calibrating inaccuracy.
Utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and a kind of motor shaft is provided, and makes dynamically balanced calibration more convenient more accurate, improves the reliability of motor shaft.
The technical solution of the utility model is:
A kind of motor shaft, comprise the axle body that is shaft-like, it is characterized in that: on described axle body, extended radially outward an axle collar, the described axle collar is coaxial with axle body, on the outer circumference surface of the axle collar, along being circumferentially evenly equipped with a plurality of balancing holes radially, described balancing hole is tapped blind hole.
Further, the quantity of balancing hole described in the utility model is 24.
The beneficial effects of the utility model are:
While 1, calibrating dynamic balancing, reasonably in the balancing hole of relevant position, screw in bolt, by the depth of adjusting bolt, carry out adjustment, operation is succinctly convenient, and accuracy is high, and reliability is high;
2, the existing balance columns that is arranged on rotor sheet assembly two ends is changed into the balancing hole being set directly on the motor shaft axle collar, make calibration more accurate;
3, from existing 8 balance columns, be increased to 24 balancing holes, without adding in addition balance mud, more convenient more accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the D-D cutaway view in Fig. 1;
Fig. 3 is the enlarged drawing at P place in Fig. 1.
Embodiment
Now in conjunction with the accompanying drawings and embodiments the utility model is further described:
As shown in Figure 1-Figure 3, a kind of motor shaft of the utility model embodiment, comprise the axle body 10 that is shaft-like, on axle body 10, extended radially outward an axle collar 20, this axle collar 20 is coaxial with axle body 10, on the outer circumference surface of the axle collar 20, along being circumferentially evenly equipped with 24 balancing holes 30 radially, balancing hole 30 is tapped blind hole.What deserves to be explained is, the structure of motor shaft need to be designed with the various different structures such as optical axis section, thread segment, keyway, escape according to the needs of variety classes motor and processing installation, and the axial location of the axle collar 20 described in the utility model on axle body 10 also determined according to various needs.
Claims (2)
