Abstract
The utility model discloses a magnetic steel sheet supporting frame, which is simple in structure, convenience to produce and arrange and economic in cost. The main body of the magnetic steel sheet supporting frame is a circular ring body, the length of the circular ring body in an axial direction is more than that of a magnetic steel sheet, and the thickness of the circular ring body in a radial direction is smaller than that of the magnetic steel sheet; the circular ring body of the magnetic steel sheet supporting frame is provided with a plurality of magnetic steel sheet holding slots side by side; and the magnetic steel sheet holding slots extend to the edge of the circular ring body along the axial direction of the circular ring body, and the width of each magnetic steel sheet holding slot is basically identical to that of the single magnetic steel sheet. According to the magnetic steel sheet supporting frame in a structure disclosed by the utility model, the installation of all magnetic steel sheets can be completed by only one magnetic steel sheet supporting frame, so that the operation steps are reduced, the production efficiency is improved, in addition, the supporting frame is convenient to machine, and thus, the cost is saved.
Description
Technical field
The utility model relates to a kind of outer-rotor structure in electric vehicle motor field, especially a kind of magnetic links bracing frame.
Background technology
External rotor is the important component part of electric vehicle motor, and itself and stator combination constitute the main part of motor together jointly.
Shown in Fig. 1 to 4, electric vehicle motor external rotor of the prior art comprises through bearing 101 being installed in the end cap 103 on the axle 102 and being fixed on the iron ring 104 on the end cap 103 that iron ring 104 inwalls are provided with a plurality of magnetic links 105; Be provided with two bracing frames 106 on iron ring 104 inwalls in opposite directions, this bracing frame 106 comprises annular stent base 107, is arranged at intervals with a plurality of support arms 108 on the bracket base 107, and support arm 108 is along the axial convexity of bracket base 107; Magnetic links 105 is installed on the bracing frame 106, and its two ends withstand on respectively on the bracket base 107, and 108 intervals of supported arm between two magnetic links 105.
Above-mentioned electric vehicle motor outer-rotor structure of the prior art; When fixing magnetic links, at first a bracing frame 106 is fixed on iron ring 104 inwalls; Then magnetic links 105 is inserted in the support arm 108; Again another bracing frame 106 symmetries are enclosed within on iron ring 104 inwalls, with glue magnetic links 105 and bracing frame 106 are bonded on the iron ring inwall at last.
In installation process, when a magnetic links was inserted between two adjacent support arms, its active force that receives was the support force straight up that bracket base applies its bottom, and two support arms of these magnetic links both sides are to its chucking power.Because support arm be along the axial convexity of bracket base, its area that contacts with magnetic links is less, and this just makes chucking power deficiency that receives after the magnetic links insertion, on bracing frame, drops easily or tilts, and makes troubles to installation.
In addition; The motor outer rotor of this structure, magnetic links is installed needs two bracing frames, so just must in two steps two bracing frames be installed in respectively on the iron ring inwall in the installation process; Its production and processing operation is loaded down with trivial details; Installation steps are complicated, make that the production efficiency of this external rotor is lower, and its production cost are higher.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure, production and easy for installation, and the magnetic links bracing frame of saving cost.
For addressing the above problem, a kind of magnetic links bracing frame of the utility model, the body of said magnetic links bracing frame is a torus, and the length of this torus on axially is greater than the length of magnetic links, and the thickness that the footpath makes progress is less than the thickness of magnetic links; On the torus body of said magnetic links bracing frame, offer several magnetic links standing grooves side by side; Said magnetic links standing groove extends axially to toric edge along torus, and the width of its width and single magnetic links is basic identical.
Said magnetic links standing groove is all apart from being opened on the torus.
Said magnetic links bracing frame is that non-magnetic conductive material is processed.
Said non-magnetic conductive material is a plastic material.
Adopt the magnetic links bracing frame of the utility model structure;, magnetic links at first this magnetic links bracing frame is fixed on the iron ring inwall when being installed; Then magnetic links is inserted in the magnetic links standing groove, with glue magnetic links and magnetic links bracing frame is bonded on the iron ring inwall again.The magnetic links bracing frame of the utility model structure; Simple in structure; Magnetic links is easy to assembling, because the width and the magnetic links of magnetic links standing groove are basic identical, when therefore being placed on magnetic links in the magnetic links standing groove; Magnetic links receives bigger chucking power, thereby guarantees that it can not drop or tilt before bonding; Adopt the magnetic links bracing frame in the utility model structure simultaneously, only need an installation of just enough accomplishing whole magnetic links, reduced operating procedure, improved production efficiency, and this bracing frame is easy to process, thereby has practiced thrift cost.
