Abstract

The utility model discloses a fixing structure for a motor insulating ring. A plurality of bosses are formed on an outer cylindrical surface of the insulating ring. The insulating ring is cooperated with an inner water jacket. An annular groove is formed in an inner cylindrical surface of the inner water jacket and is communicated with a plurality of embedded notches. The number of the embedded notches is the same with the number of the number of the bosses. The bosses of the insulating ring are embedded in the annular groove through the embedded notches of the inner water jacket. The practical installation positions of the bosses and the positions of the embedded notches are distributed in a staggered manner. The bosses on the insulating ring and the annular groove in the inner water jacket cooperate to form the fixing structure. The bosses avoid the notches of the inner water jacket and then enter the annular groove, and the bosses of the insulating ring are pressed by means of the top surface of the annular groove. The fixing structure is simple and reliable, a fixing effect can be achieved easily without requiring external components, and a motor is ensured to operate normally.

Description

The fixed structure of electrical machine insulation ring

Technical field

The utility model is relevant with motor, especially belongs to a kind of fixed structure of electrical machine insulation ring.

Background technology

In mixed power electric car, motor can be subject to larger vibration under the impact of engine, and in motor vital part---dead ring is not taked effective fixation, thereby easily cause with dead ring connecting coil because of vibration generation fracture failure, this will cause very serious impact to motor, finally cause motor normally to work.At present, the dead ring of motor mainly relies on six legs (reference column) of its bottom to position, and this leg does not play fixation, and therefore the safety in utilization of dead ring is poor.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of fixed structure of electrical machine insulation ring, is not increasing on the basis of additional parts, realizes reliable fixing by the dead ring and the inner water sleeve that cooperatively interact, ensures the normal work of motor.

For solving the problems of the technologies described above, the fixed structure of the electrical machine insulation ring that the utility model provides, the external cylindrical surface of described dead ring is formed with some boss, this dead ring matches with the inner water sleeve of motor, some embedding notches that the inner cylinder face of described inner water sleeve is formed with a cannelure and is communicated with this cannelure, the quantity of described embedding notch is identical with the boss quantity of dead ring, the boss of described dead ring is embedded in cannelure by the embedding notch of inner water sleeve respectively, and the actual installation position of boss is in staggered distribution with the position that embeds notch.

In addition, the utility model also provides a kind of fixed structure of electrical machine insulation ring, the external cylindrical surface of described dead ring is formed with some boss, this dead ring matches with the inner water sleeve of motor, the inner cylinder face of described inner water sleeve is formed with some sections of deep-slotted chip breakers, on every section of deep-slotted chip breaker, there is an embedding notch, the quantity of described deep-slotted chip breaker is identical with the boss quantity of dead ring, the boss of described dead ring embeds notch by one respectively and is embedded in corresponding deep-slotted chip breaker, and the actual installation position of boss is in staggered distribution with the position that embeds notch.

In above-mentioned two kinds of technical schemes, further, described boss is in the excircle direction of dead ring and non-uniform Distribution, and described embedding notch is in inner periphery direction the non-uniform Distribution of inner water sleeve.

Wherein preferred, described boss and notch are three.

The utility model coordinates formation fixed structure by the boss on dead ring with cannelure or deep-slotted chip breaker on inner water sleeve, after staggering, the embedding notch position of boss and inner water sleeve enters cannelure inside or deep-slotted chip breaker inside, rely on the end face of cannelure or deep-slotted chip breaker to push down dead ring boss, this is simple and reliable for structure, just can easily fix without increasing additional parts, ensure the normal work of motor.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

In the fixed structure of the described electrical machine insulation ring of the utility model preferred embodiment, the external cylindrical surface of dead ring 2 is formed with some boss 3, as Fig. 3, shown in Fig. 4, this dead ring 2 matches with the inner water sleeve 1 of motor, some embedding notches 5 that the inner cylinder face of described inner water sleeve 1 is formed with a cannelure 4 and is communicated with this cannelure 4, as Fig. 5, shown in Fig. 6, the quantity of described embedding notch 5 is identical with the boss of dead ring 3 quantity, the boss 3 of described dead ring 2 is embedded in cannelure 4 by the embedding notch 5 of inner water sleeve 1 respectively, and the actual installation position of dead ring 2 fixing rear boss 3 is in staggered distribution with the position that embeds notch 5, as Fig. 1, shown in Fig. 2.

Wherein, in preferred embodiment, boss 3 is equally distributed in the excircle direction of dead ring 2, and as shown in Figure 3, similarly, embed notch 5 is also equally distributed in the inner periphery direction of inner water sleeve 1, makes like this structure more reliable and stable.Certainly, boss 3 and embedding notch 5 also can distribute by non-equidistance, as long as the two corresponding distribution.

In the present embodiment, as shown in Figure 3, boss and notch are three, and the quantity of this boss and notch can arrange as required.

In addition, cannelure can also replace with other equivalent structure form, as cannelure being divided into the form of multistage deep-slotted chip breaker, or cannelure is shortened to draw-in groove form and changes boss into buckle or barb form etc., and to be all that those skilled in the art are easy just can expect and realize these structures.

The utility model coordinates formation fixed structure by the boss on dead ring with cannelure or deep-slotted chip breaker on inner water sleeve, boss slips into by the embedding notch of inner water sleeve in the cannelure or deep-slotted chip breaker of inner water sleeve, after again inner water sleeve being rotated to an angle in a circumferential direction, boss leaves and embeds the position of notch and enter cannelure inside or deep-slotted chip breaker inside, rely on the end face of cannelure or deep-slotted chip breaker to push down dead ring boss, this is simple and reliable for structure, without increasing just light fixed effect of additional parts, ensure the normal work of motor.

By specific embodiment, the utility model is had been described in detail above, this embodiment is only preferred embodiment of the present utility model, and it not limits the utility model.In the situation that not departing from the utility model principle; the aspect such as shape/quantity/distribution form and the fit system between the two of those of ordinary skill in the art cross sectional shape/quantity/distribution form to cannelure, boss under the prerequisite of not making creative work by any amendment, be equal to all other embodiment that the modes such as replacement, improvement obtain, in the technology category that all should be considered as protecting at the utility model.
