The synchronous motor is rapid and convenient to install, high in accuracy and capable of improving production efficiency greatly and reducing cost simultaneously.

Description

A kind of synchronous machine with quick mounting structure

Technical field

The utility model relates to a kind of synchronous machine, particularly a kind of gear reduction claw-pole permanent magnet synchronous motor with quick mounting structure.

Background technology

Like Fig. 1 and shown in Figure 2, the stator 2 that present gear reduction claw-pole permanent magnet synchronous motor comprises metal shell 1, be made up of positive secondary coil and pawl pole plate, the rotor 4, reduction box 5 and the back-up ring 6 that 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 easy for installation, the permagnetic synchronous motor that positioning stablity and precision are high.

For reaching the purpose of the utility model; The synchronous machine of the utility model changes stator, rotor and the reduction box that original two circlip grooves that on the metal shell of motor, adopt Vehicle Processing to form fix synchronous machine; But utilize mould and punch press on metal shell, to carry out the four sides punching, utilize the precision of mould and punch press to guarantee the height dimension of four location holes.When motor is installed, do not re-use back-up ring, utilize specific purpose tool that electric motor end cap is compressed back four location holes that are screwed on the metal shell that rotate together with reduction box and get final product.

The beneficial effect of the utility model is:

1. raise the efficiency, reduce cost: because the improvement of processing technology, the installation of motor is more simple and efficient, and production efficiency is greatly improved, thereby has reduced labor cost; In addition owing to do not re-use the standard back-up ring, thereby reduced unit cost;

2. motor performance promotes: because the improvement of processing technology, the location hole on the motor housing makes motor shaft controlled to fit dimension, vibration and the noise of having avoided motor to be produced owing to long-time running, the useful life of improving motor;

3. increase the motor Installation Flexibility:, make that the motor output shaft direction can be arbitrarily adjustable at the four direction of motor installed surface, thereby increased the motor installation flexibility because the cooperation location hole is increased to four by original two on end cap and the metal shell;

4. anti-dismounting:, help the after-sale service of product because the change of electric motor mounting structure needs specific purpose tool just can dismantle, thereby increased the confidentiality of motor.

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 synchronous machine of the prior art of Fig. 1;

Shown in Figure 3 is the 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, comprise at least two location holes 30 that on metal shell, carry out punching formation through mould and punch press on the described metal shell 1.Preferably, said location hole 30 is four, is evenly distributed around metal shell 1 co-altitude.When motor is installed, do not re-use back-up ring, utilize specific purpose tool that electric motor end cap is compressed back four location holes 30 that are screwed on the metal shell 1 that rotate together with reduction box and get final product.On metal shell, carry out the four sides punching through mould and punch press, utilize the precision of mould and punch press can guarantee the height dimension of four location holes.

The synchronous machine of the utility model is compared original motor output shaft when mounted can only realize location and installation two lateral location with end cap, can realize location and installation (be separated by 90 ° and distribute) four lateral location, increases its Installation Flexibility; In addition, motor originally adopts standard back-up ring location and installation, just can realize random dismounting with general tool, and the motor of the utility model must use complicated specific purpose tool could realize dismounting increasing its confidentiality, helps after services of product; In addition, adopt the punching pattern, guarantee that with the precision of mould and punch press can avoid the people is the mismachining tolerance that causes, error generally can be controlled in the 0.05mm, helps the lifting of properties of product, the useful life of prolongation motor; Also need increase deburring operation after the tank car processing that fixedly back-up ring is used of original in addition motor, operation is many, and personnel are assorted; And the utility model adopts the punching pattern, can reduce by 90% manpower, and production efficiency can improve 10 times, adds not re-use the hole and use back-up ring, makes unit cost reduce by 2%, thereby has improved the product core competitiveness.

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.

Claims (2)

1. permagnetic synchronous motor; The stator (2) that comprises metal shell (1), forms by positive secondary coil and pawl pole plate, the rotor (4) and the reduction box (5) that constitute by permanent magnetic ring; It is characterized in that, comprise on the described metal shell (1) through mould and punch press and on metal shell, carry out at least two location holes (30) that punching forms.
