Specific implementation mode
As shown, a kind of low-power machine described in the embodiment of the present invention, including：As shown in Fig. 2, the both ends of upper cover 2
Process through-hole 21 and upper positioning convex shoulder 22；As shown in figure 3, the both ends thread mill drilling 71 of lower cover 7 and lower positioning convex shoulder 72；Such as figure
Shown in 2, the middle part of upper cover 2 and lower cover 7 is machined with spherical surface axle sleeve location hole 23 and counterbore 24, is heavy shoulder 25 in counterbore 24, sinks
Riveting press groove 26 is also machined on the circumference in hole 24, as shown in fig. 7, spherical surface axle sleeve 3 is installed in spherical surface axle sleeve location hole 23 and matches
Flexible catch 5, elastic block piece 5 is limited by heavy shoulder 25 and riveting press groove 26, as shown in figure 4, elastic block piece 5 is thin rounded flakes, circle
Bending section 51 is formed after the middle part punching press star of shape thin slice；As shown in fig. 7, spherical surface axle sleeve 3 is under the elastic reaction of bending section 51
Always it is fitted in spherical surface axle sleeve location hole 23；As shown in Figure 1,4 both ends of rotor pass through spherical surface axle sleeve 3 and are movably arranged on upper cover
Between 2 and lower cover 7；As shown in fig. 6, symmetrical machining bolt hole 11 on holder 1, the upper and lower side of bolt hole 11 is convex shoulder location hole
12, as shown in Figure 1, upper cover 2, lower cover 7 are fixed on holder 1 by bolt 6；The size of upper positioning convex shoulder 22 and lower positioning convex shoulder 72
Unanimously, upper positioning convex shoulder 22 is matched with convex shoulder location hole 12；There is also magnetic fields in holder 1.
Rotor is installed using spherical surface axle sleeve, can be solved due to the location hole of upper and lower covers in actual processing and installation process
