Description

The novel rotor of generator

The utility model relates to the rotor arrangement of generator.

The rotor part of the generator that uses is by the pawl utmost point at present, coil, skeleton, metal axle sleeve, axle is formed, axle sleeve coincide with axle and is integral (being that skeleton is fixed on the axle by axle sleeve) because axle sleeve is that metal material is heavier, make the weight of rotor strengthen the startup load greatly, its the pawl utmost point is forged by steel plate and makes, need punch ram in the processing, equipment such as mould cause the card that does not have groove and projection on the high pawl utmost point of production cost and the skeleton, the pawl utmost point and skeleton can not be located, skeleton is rotatable in extremely at pawl, the pawl utmost point and skeleton rock mutually during assembling, bad location easily causes two pawl utmost point space widths unbalanced.So after the assembling, axle when driving the running of the pawl utmost point by axle sleeve rotor takes place easily sweeps faults such as hall, coil connecting line.Make the generator lost of life, assemble coarse and influenced the overall efficiency of generator.Because the pawl utmost point is made by low-carbon steel material, so the permeability height, electrical loss Da Yi produces eddy current and makes that the motor feels hot again.

It is in light weight that the purpose of this utility model is that provide in order to address the above problem a kind of removes axle sleeve, form by parts such as the pawl utmost point of the hot investment casting that has locator card and groove and skeletons, assembling is simple, has good positioning and also can improve the novel rotor of the generator of complete machine generating efficiency.

Below in conjunction with description of drawings technology contents of the present utility model.

From Fig. 1, can clearly find out at the outer side plane 3 of the pawl utmost point 1 setting circle groove 4 is arranged, from figure 2, Fig. 3 finds out on the inner side plane 5 of the pawl utmost point 1 two detents 6, as shown in Figure 5, and skeleton 2 Locator card 9 is arranged, such as Fig. 4, shown in Figure 6, outside having on another circular planes 8 of skeleton 2 on the circular planes 7 The lead-in wire ear 12, locator card 11, include the lead-in wire ditch (15) locator card 13, lead ditch 14 and limiting card 10, during assembling skeleton 2 is placed in the pawl utmost point 1, with card and groove both are tightly located chucking. Such as Fig. 1 institute Show that the circle center line connecting of the center of circle of the setting circle groove 4 on the outer side plane 3 of the pawl utmost point 1 and axis hole 16 is with logical The angle α that crosses the vertical center line in axis hole 16 centers of circle is 30 °, puts down such as the interior of Fig. 2, the pawl utmost point 1 shown in Figure 3 Two central lines of 6, two detents 6 of two rectangle detents are arranged on the face 5 and pass through In the outside, the center of circle of axis hole 16 (namely being symmetrically distributed on the pawl utmost point inner side plane edge) the disk groove 4 The center line angle of two grooves 6 on heart line and the inner side plane is 60 °, as shown in Figure 5 the circle of skeleton 2 Locator card 9 on the plane of a loop 7 is square protrusion, and as can be seen from Figure 5, the center line of locator card 9 passes through The angle β of the center line that passes through the center of circle on the center of circle of skeleton 2 and the outer lead ear 12 is 30 °, as Fig. 4, The annulus that is distributed in skeleton 2 that is shaped as L shaped their symmetry of two outer lead ears 12 shown in Figure 6 is flat Face 8 is along upper, one of them outer lead ear 12 on the edge of locator card 11 anchor rings of living in, 11 shape Be rectangular projection, including the straight of lead-in wire ditch 15 such as Fig. 6, another outer lead ear 12 shown in Figure 7 Angle locator card 13 circular planes of living in along upper, the lead-in wire ditch 15 communicate with lead ditch 14,4 limits are arranged Position card 10 is shaped as T shape projection, their both sides that are distributed in two outer lead ears 12 symmetrically. Rectangle locator card 11 on the skeleton 2 includes the right angle locator card 13 and the pawl utmost point 1 inboard of lead-in wire ditch 15 Two detents 6 on the plane 5 coincide and block the projection of 4 T shape limiting cards 10 on the skeleton 2 Be stuck in the between cog position of the pawl utmost point 1, on the square protrusion locator card 9 and another pawl utmost point 1 on the skeleton 2 A detent 6 coincide. Skeleton and pawl utmost point location is blocked, and two pawl utmost point location are not loosening yet. Turn to When assembling son, forcing press by with the pawl utmost point 1 outer side plane 3 on setting circle groove 4 cooperate pressurization, make pawl The detent 6 of the utmost point 1 locates chucking with the locator card 11,13 of skeleton 2. The pawl utmost point 1 is by little carbon steel Material is made.

The novel rotor of generator, the pawl utmost point adopts little carbon steel material, and the pawl machine takes hot investment casting to form, not only Greatly reduce the processing and manufacturing cost, permeability is low, and the few power generation performance of power consumption improves, and the pawl utmost point 1 He Locating slot and card are arranged on the skeleton 2, thus when assembling skeleton 2 and the pawl utmost point 1 be easy to the location chucking, do not shake Moving, can assemble from start to finish consistent reliably, improved assembly precision, and assembling is simple, improved assembling Quality and quantity. Because axle directly drives the pawl utmost point and rotates, and makes the space width equilibrium of the pawl utmost point, has improved dynamic balancing Stability is difficult for taking place rotor and sweeps the faults such as hall, coil connecting line. On the other hand, owing to cancelled axle sleeve, subtract Light weight has reduced and has started load, and reduced cost. Fault is low, the life-span is long, has improved generator Overall efficiency.
