Abstract
The utility model relates to a single-support motor rotor. The single-support motor rotor comprises a main body segment. Only one end of the main body segment is equipped with a supporting segment. The main body segment includes a cylindrical surface segment and a conical surface segment that are arranged in order. The cylindrical surface segment is positioned between the supporting segment and the conical surface segment. One larger end of the conical surface segment is connected with the cylindrical surface segment end-to-end. The conical surface segment, the supporting segment and the cylindrical surface segment are coaxial. The radius of one larger end of the conical surface segment is equal to the radius of the cylindrical surface segment. The single-support motor rotor provided by the utility model prevents a single-rotor motor from being noticeably decreased in performance once a phenomenon that a rotor bumps a stator occurs, helps to overcome a problem that the phenomenon that a rotor bumps a stator is not restricted by a single-support motor usage environment, and helps to solve problems that the conventional technical scheme for solving the bumping phenomenon cannot give consideration to both less decrease of the performance of a motor and no restriction of a single-support motor usage environment.
Description
Technical field
The utility model relates to single support motor, relates in particular to a kind of single supporting motor rotor.
Background technology
Motor is commonly called as " motor ", refers to a kind of calutron of realizing electric energy conversion or transmit according to the law of electromagnetic induction.Be 93231403 in China Patent No., Granted publication day be Mays 11 nineteen ninety-five day, be called in the patent documentation of " motor " and disclose a kind of motor.The structure of motor is as disclosed in this patent, comprise shell, be fixed on the stator in shell and be positioned at the rotor of stator, the endoporus of the installation rotor of stator is cylindrical hole, and the side face of rotor is the face of cylinder.Rotor in motor in this patent is that two ends are all provided with supporting section, is supported in shell by bearing is installed on supporting section.In actual design, in order to improve the reasons such as the compactedness of electric machine structure, the rotor of some motor only one end is provided with supporting section, and when use, rotor only supports by the one end that is provided with supporting section, and the motor that this kind only supports one end of rotor is called single support motor.But single support motor is owing to making the reasons such as error, when use, rotor easily produces radially rocking taking support end as the strong point, this radially rocks and can cause motor generation to sweep a phenomenon (being the phenomenon that rotor collides with stator), and generation is swept a phenomenon and can be caused rotor stator wear damage and produce noise.Sweep a phenomenon in order to solve single support rotor motor generation, existing improving one's methods as increasing the gap (claiming again air gap) between stator and rotor, but it is the smaller the better that motor performance is air gap, therefore solve by the method for single increase air gap a problem of sweeping and can cause motor performance to decline obviously.Another kind method, for by design specialized connector, makes motor solve with carrying out syndeton between driven member a problem of sweeping by special connecting piece when use.Be 2008200997640 in China Patent No., Granted publication day is that the patent document that June 3 in 2009, day, were called " single support motor elastic damping shaft coupling " discloses a kind of for solving the special connecting piece of sweeping a problem.The method of design specialized connector can not be used in when the service condition that support motor directly links together with driven member, also can not solve be used in this environment single support motor sweep a phenomenon, therefore versatility is poor.
Utility model content
The utility model provides a kind of and has overcome single-rotor motor and produce and while sweeping phenomenon, cause motor performance decline little and solve single supporting motor rotor of sweeping a phenomenon and not being subject to single support motor environment for use restriction, has solved the single support motor of existing solution and has swept the problem that hydraulic performance decline that the technical scheme of a phenomenon can not take into account motor is little and not restricted by single support motor environment for use.
Above technical problem solves by following technical proposal: a kind of single supporting motor rotor, comprise main paragraph, described main paragraph only one end is provided with supporting section, described main paragraph comprises the cylinder section and the conical surface section that set gradually, described cylinder section is positioned between described supporting section and conical surface section, the bigger diameter end of described conical surface section is docking together with described cylinder section, and described conical surface section, supporting section and cylinder section three are coaxial, and the radius of described conical surface section bigger diameter end equates with described cylinder section radius.When use, main paragraph is positioned at stator and matches with stator, is rotatably supported in and in stator or motor housing, is realized the fixing of rotor by supporting section.In the time that in rotor operation process, the taper of generation taking supporting section as summit rocked, the amplitude that the part far away apart from supporting section radially rocked is larger, by one end design conical section away from supporting section at rotor, thereby can effectively avoid sweeping a phenomenon, make air gap recruitment few again.Owing to being the structure of non-support end that changes rotor, so be not subject to the restriction of environment for use, provide a kind of technological means with versatility for a phenomenon of sweeping that overcomes single support motor.
As preferably, described conical surface section drift angle
, wherein H is that cylinder segment length, R are that cylinder section radius, L are that cylinder section is with the gap between stator.When rotor rocks one end that cylindrical section connects with conical section while contacting with stator inner wall, now the bus of conical section is just parallel with the axis of stator and be intermittently zero.Can be in the situation that cylindrical section be certain with stator air gap, realize the air gap amount optimization of avoiding most effectively sweeping a phenomenon and conical section.
As preferably, described conical surface segment length is below 1/2nd and more than 1/4th of described cylinder segment length.Can reasonably take into account and overcome the increase of sweeping a phenomenon and reducing air gap amount, ensure the performance of motor.
The utlity model has following advantage: by rotor away from one end design conical section of supporting section and the miner diameter end of conical section away from supporting section, can effectively avoid sweeping a phenomenon, make air gap recruitment few again, the decline that the increase of air gap amount less, can make to overcome the motor performance of sweeping a phenomenon and cause is few; Realize overcoming and sweep a phenomenon by changing the structure of non-support end of rotor, be not subject to the restriction of environment for use, provide a kind of technological means with versatility for a phenomenon of sweeping that overcomes single support motor.
