Abstract
The utility model discloses a kind of yoke of permanent magnet iron coreless motor and the mounting structure of axle, it comprises axle and two the permanent magnetism body discs be arranged on axle, permanent magnetism body disc is attached in yoke by permanent magnet magnet steel and forms, the axle body of described axle is radially extended with the first annular boss, first annular boss is radially extended with the second annular boss, the center superposition of the first annular boss and the second annular boss, the left and right end face that two yokes are close to the second annular boss is respectively arranged on the first annular boss, and the permanent magnet magnet steel in two yokes corresponds to each other.Mounting structure of the present utility model decreases the cutting output of processing yoke, improves raw-material utilization rate, reduces production and processing cost, make assembling more easy simultaneously.
Description
Technical field
The utility model belongs to permanent magnet iron coreless technical field of motors, particularly relates to a kind of yoke of permanent magnet iron coreless motor and the mounting structure of axle.
Background technology
At present, in existing permanent magnet iron coreless motor, the mounting structure of yoke and axle as shown in Figure 1, and permanent magnet magnet steel 3 is attached in yoke 4 and forms permanent magnetism body disc, and two permanent magnetism body discs rotate by flat key or spline band moving axis the rotor forming motor.In above-mentioned existing structure, yoke is provided with the gap that boss B 5 ensures between two yokes, in order to limit the axial motion of yoke, axle is provided with one end that boss A 2 fixes yoke, also need design element 6 to fix the other end of yoke, this existing structure is complicated, assembles loaded down with trivial details simultaneously, and the cutting output of processing yoke is comparatively large, compares expense material.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of yoke of permanent magnet iron coreless motor and the mounting structure of axle.
In order to realize technique scheme, the utility model adopts technical scheme as described below:
A kind of yoke of permanent magnet iron coreless motor and the mounting structure of axle, it comprises axle and two the permanent magnetism body discs be arranged on axle, permanent magnetism body disc is attached in yoke by permanent magnet magnet steel and forms, the axle body of described axle is radially extended with the first annular boss, first annular boss is radially extended with the second annular boss, the center superposition of the first annular boss and the second annular boss, the left and right end face that two yokes are close to the second annular boss is respectively arranged on the first annular boss, and the permanent magnet magnet steel in two yokes corresponds to each other.
Owing to adopting technique scheme, the utility model has following superiority:
The mounting structure of this yoke and axle decreases the cutting output of processing yoke, improves raw-material utilization rate, reduces production and processing cost, makes assembling more easy simultaneously.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram of yoke and axle in prior art;
Fig. 2 is structural representation of the present utility model;
In figure: 1-axle; 2-boss A; 3-permanent magnet magnet steel; 4-yoke; 5-boss B; 6-element; 7-first annular boss; 8-second annular boss.
Embodiment
As shown in Figure 1, a kind of yoke of permanent magnet iron coreless motor and the mounting structure of axle, it comprises axle 1 and two the permanent magnetism body discs be arranged on axle 1, permanent magnetism body disc is attached in yoke 4 by permanent magnet magnet steel 3 and forms, the axle body of described axle 1 is radially extended with the first annular boss 7, first annular boss 7 is radially extended with the second annular boss 8, the center superposition of the first annular boss 7 and the second annular boss 8, the left and right end face that two yokes 4 are close to the second annular boss 8 is respectively arranged on the first annular boss 7, permanent magnet magnet steel 3 in two yokes 4 corresponds to each other.
Described two yokes 4 are connected by key with between the first annular boss 7, and flat key can be adopted to connect, and multiple flat key or spline or alternate manner also can be adopted to connect.
In mounting structure of the present utility model, two yokes are attracted each other by the magnetic force of permanent magnet magnet steel thereon and are fixed on the both sides end face of the second annular boss, can not produce axial motion; In addition, the both sides end face of the first annular boss on axle also may be used for the bearing of location and installation on axle, and without the need to other element, mounting structure is simple, quick.
