Abstract
Provided is a proper alignment mechanism for testing speed of a motor, the alignment mechanism for testing speed of the motor comprises a motor shaft end portion, an inner threaded hole, a small axle construction, a fastener, a protruding platform mechanism is machined on the motor shaft end portion, a plurality of inner threaded holes are formed in the protruding platform, a groove type construction is arranged at the joint of both the small axle construction and the end portion of the motor shaft end portion, the fastener corresponded to the inner threaded holes is arranged on the groove type construction. The proper alignment mechanism for testing speed of the motor takes advantage of the feature of not high manufacturing precision of loop line contact to the shaft end surface, thereby effectively guaranteeing the proper alignment. The proper alignment mechanism for testing speed of the motor further has the advantages of being high in manufacturability, thereby highly improving producing efficiency.
Description
Technical field
The present invention relates to machine field, relate in particular to a kind of motor speed measuring right alignment structure.
Background technology
The measured motor rotating speed is used for the mode of closed-loop speed FEEDBACK CONTROL, usually adopts the shaft extension end face at anti-drive end to reconnect a little axle that rotates simultaneously with motor shaft, and this little axle and speed measuring device are integrated.Because of the right alignment of little axle and motor shaft require very high, so their face that interconnects and mode play very important effect.Traditional way is to adopt high precision machine tool and guarantee than labyrinth, has limited the process conditions means, makes production cost increase Efficiency Decreasing.
Summary of the invention
The purpose of this invention is to provide that a kind of manufacturability is simple, production efficiency is high, cost is low, right alignment easily meets the requirements of motor speed measuring right alignment structure.
The present invention realizes like this, a kind of motor speed measuring right alignment structure, comprise motor shaft end, internal thread hole, little axle construction, securing member, it is characterized in that: motor shaft is processed with boss structure on the end, be provided with several internal thread holes at boss, the junction of little axle construction and motor shaft end is set to the groove type structure, and the securing member corresponding with internal thread hole is set thereon.
Further, the degree of depth of the groove of described little axle construction is greater than land length 1 ~ 3mm; The interior circular diameter of described little axle construction groove and the difference of outside diameter are less than 6mm.
The present invention utilizes the loop wire contact characteristics not high to the axial end requirement on machining accuracy, has effectively guaranteed right alignment, and very strong manufacturability is arranged, and production efficiency has obtained greatly improving.
Description of drawings
Fig. 1 is the structural representation of the motor shaft end among the present invention;
Fig. 2 is the structural representation of the little axle among the present invention.
Among the figure: 1, motor shaft end, 2, boss, 3, internal thread hole, 4, little axle construction,
5, securing member.
Embodiment
Below in conjunction with accompanying drawing this patent is described further
A kind of motor speed measuring right alignment structure, comprise motor shaft end 1, internal thread hole 3, little axle construction 4, securing member 5, it is characterized in that: be processed with boss 2 structures on the motor shaft end 1, can process at one time, efficient is high, being provided with several internal thread holes 3 at boss 2 is used for being connected with little axle construction 4, little axle construction 4 is processed as the groove type structure with the junction of motor shaft end 1, the securing member 5 corresponding with internal thread hole 3 is set, for being connected with motor shaft end 1 thereon; The degree of depth of the groove of described little axle construction 4 is greater than boss 2 length 1 ~ 3mm, not only guarantees the close contact of little axle construction 4 and motor shaft end 1, and reserves the delivery space of fifth wheel to burr, and shop characteristic is strong; The interior circular diameter of described little axle construction 4 grooves and the difference of outside diameter are less than 6mm, and namely Φ D-Φ d≤6mm so that motor shaft end 1 adopts loop wire to contact with little axle construction 4, thereby has reduced the end face requirement on machining accuracy to motor shaft end 1.
