Abstract
The invention discloses a double-layer round-key assembly structure for a stator. The structure comprises a connecting structure of which the joint between a stator core (2) and a base (1) is provided with a cylindrical pin (3). In the structure, two or more semicircular holes are equally reserved in the circumferential direction of an inner hole in the center of the stator core (2); and two or more semicircular holes are also equally reserved in the outer circumferential direction of a cylinder in the center of the base (1); the cylindrical pin (3) is inserted into a circular hole formed by the base (1) and the stator core (2) correspondingly, so that not only a torsional force transfer effect is achieved, but also the stator core (2) and the base (1) are concentric; in addition, the relative movement between the stator core (2) and the base (1) is prevented so as to ensure a certain gap between the outer circle of the stator core (2) and the base (1) and avoid electric leakage, a short circuit and the like caused by the friction between a stator core coil and a silicon-steel sheet. The double-layer round-key assembly structure for the stator is simple and convenient to operate, along with a compact structure, stable performance, long service life and high manufacturability.
Description
Technical field
The present invention relates to rare-earth triphase synchronous motor, relate in particular to the double-deck round key formula of a kind of stator package assembly bindiny mechanism.
Background technology
Traditional stator core (stator core is to be formed by rivet combination by the multi-disc silicon steel sheet) mainly is that singly-bound connects with the propeller boss connecting mode of support, it is to pull out keyway respectively at the counterpart of power transmission shaft and driving element that singly-bound connects, and insert keyway with two connections with a key, its major defect is to connect the gap can't overcome, in addition in order to make the motor compact overall structure, the structural limitations of support connect the degree of depth of keyway, the integral width of the keyway depth ratio stator core of support is little, all silicon steel sheets can not all come consistent transfer torque power by key in the stator core thereby make, always there is certain clearance between rivet hole in the stator core and the rivet, in working order, in silicon steel sheet on the key and meeting generation relative motion under the effect of the silicon steel sheet on the key at torsional forces, thereby the coil in the friction stator core can often cause electric leakage, short circuit etc.
Summary of the invention
The objective of the invention is: the double-deck round key formula of a kind of stator package assembly is provided, and part manufacturing processing is simple, and propeller boss connects, convenient disassembly, long service life, and transmission is effective.
Technical scheme of the present invention is: the double-deck round key formula of a kind of stator package assembly, comprise support, stator core, the cylindrical excircle direction in described support middle part is provided with two or more semicircle orifices, described stator core middle part endoporus circumferencial direction is provided with two or more semicircle orifices, the semicircle orifice of described support and the semicircle orifice of stator core can corresponding circular holes of forming, described circular hole and the mutually close-fitting connection of straight pin.
Below technique scheme is further explained:
The first-class branch of described stator core middle part endoporus circumferencial direction offers the semicircle orifice of two or more stator core full durations.
But the first-class branch of the described support cylindrical excircle direction in middle part offers the semicircle orifice of two or more covering stators full duration unshakable in one's determination.
The cylindrical excircle direction in described support middle part is provided with three semicircle orifices, and described stator core middle part endoporus circumferencial direction is provided with three semicircle orifices.
The first-class branch of described stator core middle part endoporus circumferencial direction offers the semicircle orifice of three stator core full durations.
But the first-class branch of the described support cylindrical excircle direction in middle part offers the semicircle orifice of three covering stators full duration unshakable in one's determination.
The semicircle orifice of described support and the semicircle orifice of stator core can corresponding circular holes of forming, and wear straight pin in the described circular hole.
Advantage of the present invention is: the double-deck round key formula of stator of the present invention package assembly, its support is connected by straight pin with stator core, makes the silicon steel sheet of stator core stressed evenly, can make stator core and support concentric again.Prevent relative moving between stator core and the support, guaranteeing has certain clearance between the outer ring of stator core and the support, avoids the coil and the silicon steel sheet friction of stator core, causes electric leakage, short circuit etc.Adopt this structure, easy and simple to handle and stable performance, long service life.
