Abstract

The utility model brings forward a synchronous motor. The synchronous motor comprises a metal housing, a stator composed of a main coil, a secondary coil and a claw-pole plate, a rotor composed of permanent magnet rings, and a reduction box, wherein a wave type spring is disposed between the stator of the motor and the bottom surface of the metal housing, and the axial assembling dimension inside the motor can be adjusted automatically through elasticity of the wave type spring. The adoption of the wave type spring with an automatic adjusting function eliminates accumulative errors generated by components and raw materials, improves the axial fit precision inside the motor, avoids axial fit clearance caused by heat generated by long-time running of the motor, and reduces vibration and noise of the motor. Therefore, the service life of the motor is prolonged and the adjustability of the motor is improved.

Description

A kind of synchronous machine with automatic mechanism

Technical field

The utility model relates to a kind of synchronous machine, particularly a kind of permagnetic synchronous motor with automatic mechanism.

Background technology

Rotor 4, reduction box 5 and back-up ring 6 as shown in Figure 1 and combine stator 2 that Fig. 2, present gear reduction claw-pole permanent magnet synchronous motor comprise metal shell 1, be made up of positive secondary coil and pawl pole plate, constitute by permanent magnetic ring.Fixedly compressing through standard back-up ring 6 of stator, rotor and reduction box realizes, and the location of back-up ring 6 is to realize the cooperating of groove 3 that is processed to form by getting on the bus with metal shell 1.Axial fit dimension for control motor internal parts; Guarantee the stability of motor long-time running; So the required precision to the groove 3 on the metal shell 1 of fixing back-up ring 6 is quite high, if the position of groove 1 is low, then back-up ring 6 is pressed and is not advanced or press not in place; Back-up ring 6 comes off easily, causes the motor internal parts to fix; If the position of groove 1 is high, then end play is big, and after the electrical power running, it is big to produce vibration and noise, and serious meeting causes motor to damage fast even can't normally use.

Summary of the invention

For solving above-mentioned the problems of the prior art; The utility model proposes a kind of permagnetic synchronous motor with automatic regulating apparatus, to remedy fixedly problem of unstable of motor installation that the possible dimensional accuracy problem owing to the groove on the motor metal shell causes or motor internal element.

For reaching the purpose of the utility model; The synchronous machine of the utility model changes the datum level of the stator installation of original motor; The technology groove of metal shell bottom is widened; Between motor stator and metal shell baseplane, increase a wave mode spring, rely on the elasticity of spring to come to regulate automatically the axial fitted position of motor internal.

Preferably, the thickness of said wave mode spring is 0.3mm.

Preferably, the material of said wave mode spring is the heat treated 65Mn of process.

The beneficial effect of the utility model is:

1. owing to increased wave mode spring with automatic adjustment function; Thereby eliminated the accumulated error that parts and raw material produced; Can error amount be reduced to 0, improve the axial quality of fit of motor internal, avoid motor because the axial fit clearance that long-time running is heated and is produced; Reduced the vibration and the noise of motor, thereby improved the useful life of motor.

2. increase the motor adjustability: because the change of motor stator and reduction box positioning reference plane, it is adjustable to make that motor internal axle square chi cun becomes, and has also increased the flexibility that internal structure of motor is adjusted.

Description of drawings

Through the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the utility model will become obvious.Wherein:

Shown in Figure 1 is the schematic perspective view of synchronous machine of the prior art;

Shown in Figure 2 is the internal structure sketch map of the synchronous machine of the utility model;

Shown in Figure 3 is the exploded perspective view of the synchronous machine of the utility model.

Embodiment

With reference to Fig. 2 and Fig. 3; The stator 2 that the synchronous machine of the utility model comprises metal shell 1, be made up of positive secondary coil and pawl pole plate, the rotor 4 and the reduction box 5 that constitute by permanent magnetic ring; Wherein, Between the baseplane of said motor stator 2 (comprising stator coil 21 and stator coil 22) and metal shell 1, increase a wave mode spring 30, rely on the elasticity of wave mode spring 30 to come to regulate automatically the axial fitted position of motor internal.

Preferably, the thickness of said wave mode spring 30 is 0.3mm.

Preferably, the material of said wave mode spring 30 is the heat treated 65Mn of process.

The datum clamp face that the motor of the utility model has changed original motor stator and reduction box is nonadjustable problem; Between motor stator and metal shell positioning reference plane, increased the wave mode spring; Can eliminate parts and raw-material mismachining tolerance; Can error amount be reduced to 0, make the internal structure of motor adjustment become possibility; In addition, the stack size that has changed the original axial parts of motor internal does not simultaneously possess regulatory function, through between motor stator and metal shell positioning reference plane, increasing the wave mode spring; Can improve the axial quality of fit of motor internal, after motor was switched on running for a long time, internal structure was heated; Through the effect of repeatedly expanding with heat and contract with cold; Inner structure size can change, and at this moment, the wave mode spring relies on its elasticity that has that the motor internal size is automatically adjusted; Can eliminate the vibration and the noise of motor, thereby prolong the useful life of motor.

The utility model is not limited to described embodiment; Those skilled in the art promptly discloses in the scope in the spirit that does not break away from the utility model; Still can do some corrections or change, so the rights protection scope of the utility model is as the criterion with claims restricted portion.
