The hollow ultrasonic motor with the completely fixed stator employs the gland nut and the locknut to realize axial positioning, not only ensures that the stator vibration modal will not be affected, but also enlarges a motor inner hole diameter.
Description
Technical field
The utility model relates to a kind of motor, especially a kind of ultrasound electric machine, specifically the hollow type ultrasound electric machine that is completely fixed of a kind of stator.
Background technology
The stator of existing hollow ultrasound electric machine is to be fixed on the stator seat, as shown in Figure 1 by uniform screw 12.There are two problems in this fixed form.1: stator rim is not to retrain fully, and stator vibration mode is exerted an influence.2: the installation base face is too big, causes center bore to reduce.
Summary of the invention
The purpose of this utility model be at existing hollow type ultrasound electric machine because fixing unstable, influence mode of oscillation and cause the limited problem of center bore, design a kind of simple in structurely, can enlarge the hollow type ultrasound electric machine that the stator of internal diameter is completely fixed.
The technical solution of the utility model is:
The hollow type ultrasound electric machine that a kind of stator is completely fixed, it comprises rotor 1, friction plate 4, stator 5, piezoelectric ceramic 6, stator seat 7, bearing 8, lining 9, precompression nut 10 and locking nut 11, rotor 1 is sleeved in the stator seat 7, stator 5 is sleeved on the stator seat 7, piezoelectric ceramic 6 cards are contained on the end face of stator 4, friction plate 4 is installed between the other end and rotor 1 end face of stator 4, lining 9 is sleeved on stator and inserts on the end in the stator seat, bearing 8 is installed between lining 9 and the stator seat inner hole surface, precompression nut 10 spinnings on the tail end of rotor 1 and by locking nut 11 location, it is characterized in that described stator by stator stop nut 2 and stator clamp nut 3 axial location on stator seat 7.
The beneficial effects of the utility model:
The utility model has been realized axial location by clamp nut and stop nut, is conducive to not only guarantee that stator vibration mode is unaffected, and can enlarges the motor diameter of bore.
The utility model is simple in structure, and is easy for installation, good reliability.
Description of drawings

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 2,3.
The hollow type ultrasound electric machine that a kind of stator is completely fixed, it comprises rotor 1, friction plate 4, stator 5, piezoelectric ceramic 6, stator seat 7, bearing 8, lining 9, precompression nut 10 and locking nut 11, as shown in Figure 2, rotor 1 is sleeved in the stator seat 7, stator 5 is sleeved on the stator seat 7, piezoelectric ceramic 6 cards are contained on the end face of stator 4, friction plate 4 is installed between the other end and rotor 1 end face of stator 4, lining 9 is sleeved on stator and inserts on the end in the stator seat, bearing 8 is installed between lining 9 and the stator seat inner hole surface, precompression nut 10 spinnings on the tail end of rotor 1 and by locking nut 11 location, described stator by stator stop nut 2 and stator clamp nut 3 axial location on stator seat 7.
Shown in Fig. 2,3, the bonding piezoelectric ceramic 6 in stator 5 one side end faces.Stator 5 endoporus and stator seat 7 matched in clearance, stator clamp nut 3 and stator stop nut 2 are screwed in and compress stator 5 on the stator seat 7.Rotor 1 bonding friction plate 4, rotor 1 pass stator seat 7 and lining 9 endoporus.Precompression nut 10 makes the surface of friction plate 4 contact with the flank of tooth of stator 5 by screw thread tension rotor 1.
Rotation precompression nut 10 when regulating the motor precompression, thus precompression nut 10 pulling rotors 1 strain is regulated the precompression that contacts between friction plate 4 and the stator 5.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
