Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as the limit to the present invention It is fixed.
It refer to Fig. 1 to Figure 13, the rotor in the present invention includes rotor core 1, the magnet steel 2 of multiple arcs and peace Catch 3 on the end face of rotor core 1.Wherein, cored location division is formed on rotor core 1, magnet steel 2 is positioned by iron core Portion and catch 3 are fixed in the circumferential exterior surface of rotor core 1.It can be realized to magnet steel 2 using iron core location division and catch 3 Axially, the mechanical positioning of circumference and radial direction.Wherein, magnet steel 2 can be made of the mode that die casting is molded, and catch 3 can use The mode of punching press is made, and its manufacturing procedure is simple and easy.
It can be seen that using above-mentioned technical proposal, magnet steel 2 can be fixed on rotor core 1 in a manner of mechanical structure, from And can solve the fixation problem of magnet steel from the structure design of magnet steel and catch, increase the reliability of rotor, have it is simple in construction, The characteristics of easy for installation, fixed reliable, cost is low.
Because the present invention fixes magnet steel by the way of mechanical structure rather than stickup, therefore can avoid using bonding method When, because compressor electric motor heating makes glue accelerated ageing, so that the problem of magnet steel comes off;In addition it also avoid in compressor The problem of refrigerant and refrigeration oil can produce chemical reaction with glue, and the requirement to glue is higher, and cost is more expensive.In addition, using machine Tool structure is fixed, it is not necessary to and need the regular hour to solidify as being pasted glue, therefore simplify production process, can be more Easily quality is controlled.
Preferably, iron core location division includes being arranged in the circumferential exterior surface of rotor core 1 and along the radial direction of rotor core 1 The first prominent location division 4, direction extension of every first location division 4 along a bus of rotor core 1, its quantity can be 4.Magnet steel mounting groove 5 is formed between two neighboring first location division 4, so, in the illustrated embodiment, each rotor core Formed with four magnet steel mounting grooves 5 on 1 surface, correspondingly, a piece of magnet steel 2 is installed in each magnet steel mounting groove 5.So, First location division 4 is that each magnet steel 2 provides circumferential positioning.
In one embodiment, the present invention can fix magnetic by way of increasing fixing groove on magnet steel using catch Steel.
For example, in two embodiments shown in Fig. 1 to Fig. 9, the present invention is in magnet steel 2 towards shape on the end face of catch 3 Into at least one locating recess 6, catch 3 includes the positioning end 7 that extends radially outwards, and during installation, positioning end 7 is caught in the positioning In depressed part 6, therefore the circumference and radial direction of magnet steel 2 can be positioned.
It is highly preferred that in the embodiment shown in Fig. 1 to Fig. 5, formed with two locating recesses on an end face of catch 3 Portion 6, and the two locating recess 6 are formed in two ends of the end face towards catch 3 of magnet steel 2, so, when catch is pacified After being attached in magnet steel mounting groove 5, the two neighboring locating recess 6 of two neighboring magnet steel 2 is combined into a complete depression, gear One positioning end 7 of piece 3 be caught in simultaneously two neighboring magnet steel 2 two neighboring locating recess 6 it is combined into the depression in, To realize radial and axial positioning.It is highly preferred that the two neighboring locating recess 6 of two neighboring magnet steel 2 combine it is T-shaped Depression, and positioning end 7 is T-shaped.Preferably, in this embodiment, locating recess 6 has a drafting angle α, and 1 °<α < 3 °, so, catch can be more easily put into locating recess 6, if α is excessive, between locating recess 6 and catch Pine was fixed, easily produces and rocks.
It is highly preferred that the circumferential lengths L1 of the fixed groove and integral circumferential length L2 of magnet steel 2 on magnet steel 2 meets 4mm< L1<L2/2, positioning end 7 includes radially connected portion and is connected to the circumferentially positioned portion of radially connected portion end, described circumferentially positioned Portion protrudes from the length L3=L1 in radially connected portion.
In a preferred embodiment, the axial length of the catch 3 in the present invention is more than the axial length of rotor core 1, And locating recess 6 is formed at the part protruded from beyond rotor core 1 of catch 3, that is, form the depression of a similar blind hole Structure.The positioning end 7 of catch 3 abuts with the bottom surface of the sunk structure, so as to form axially position.In the present invention, catch 3 Locating recess 6 can be formed on two end faces, the distance between bottom surface of locating recess 6 on two end faces and rotor iron The axial length of core 1 is equal.
In the second embodiment shown in Fig. 6 to Fig. 9, unlike first embodiment, locating recess 6 is formed in magnetic Centre position between two ends of the end face towards catch 3 of steel 2, so, each catch 3 can be individually fixed by one Position end 7 is positioned, and in the first embodiment, each positioning end 7 is then determined the end of two neighboring catch 3 simultaneously Position.It is highly preferred that in a second embodiment, positioning end 7 and locating recess 6 are T-shaped.
In the 3rd embodiment shown in Figure 10 to Figure 13, unlike the first and second embodiments, the iron during this is bright Core location division also includes the second location division 8, and it is turned by a part edge of two side walls towards magnet steel 2 of the first location division 4 The peripherally and outwardly extension of sub- iron core 1 is formed, and the first location division 4 and the second location division 8 are set in cross.Correspondingly, can be It is caught on the end face of the first location division of direction 4 of magnet steel 2 formed with locating recess 6, the second location division 8 in locating recess 6. So, by the second location division 8 and the cooperation of locating recess 6, the radial direction of magnet steel 2 can be positioned.It is highly preferred that positioning Depressed part 6 forms a groove through the end face of the first location division of direction 4 of magnet steel 2.
In order to realize the axially position to magnet steel 2, in the third embodiment, catch 3 can be with rounded, and circular diameter It is less than the external diameter of magnet steel 2 more than the internal diameter of magnet steel 2, so as to block the end of magnet steel 2, its axial direction is positioned.Example Such as, the external diameter R1 of the cylindrical body of the diameter R of the circular body of catch and rotor core, the maximum outside diameter of the first location division 4 Meet between R2:(R1+2) < R < R2.
In the present invention, in order to fix catch 3, multiple rivet mounting hole A9 can be formed on catch 3, correspondingly, are being turned Multiple rivet mounting hole B10 are formed on the end face of sub- iron core 1.During installation, catch 3 is by being arranged on rivet mounting hole A9 and rivet Rivet 11 in mounting hole B10 is installed on the end face of rotor core 1.
Present invention also offers a kind of motor, particularly a kind of magneto, it includes above-mentioned rotor.
